Anker PowerCore+ Mini, 3350mAh Lipstick-Sized Portable Charger (Premium Aluminum Power Bank), One of The Most Compact External Batteries, Compatible with iPhone Xs/XR, Android Smartphones and More

I am relatively new to the whole smartphone thing -- I only got my first smartphone in the summer of 2013 -- so I continue to struggle to adapt to the different landscape that is the smartphone. A "feature phone" (or "dumb phone," as my dad calls it) has a battery that can last for several days of moderate use. A smartphone can last about a day and a half of moderate use, and forget about using it heavily for a day. Your battery will run out, and you are left looking for an outlet (and hoping that you remembered a charger), or you are suddenly without your phone! This happened to me one too many times, and I came to Amazon looking for a device like my friends' iphone second-battery attachment, but for a different type of smartphone.What I found instead was a little "lipstick-style" battery pack that I could attach as needed to my smartphone to have an extra portable charge. I was skeptical -- can a whole charge really fit in something this size? And does it make sense to charge from a device like this? I'm not an electrical engineer, but I remember a whole thing about AC to DC to AC conversion that a friend of mine told me once. Still, it was worth a shot, so I got one. In short, I am extremely pleased with this device. Let me tell you why.1. Portability. They say it's a "lipstick style" battery pack, but you should know it is bigger than a lipstick. It's about the size of a roll of quarters, though, so it's not that much bigger. It's reasonably light, and it comes with a little usb cord and a little cloth baggie to put both the battery pack and the cord into. I wouldn't say that you should carry this around in your jeans pocket -- it would be a little bulky for that -- but it definitely could go in a medium-sized purse or a coat pocket or briefcase. In a standard backpack, you'll forget it's there until you need it. You can even have your phone plugged into it while you carry the phone around, if you don't mind the bulk of the two items in your pockets at the same time.2. Functionality. It charges pretty quickly, or at least no more slowly than my wall/car charger does. I have charged my smartphone (a Samsung Galaxy Stellar) from about 10% to 100% with no problem, and I even used this to charge a digital camera with an internal battery. In fact, I used it to power AND charge that camera, so I was able to use the camera even as it charged. I'm not sure how much charging the battery pack can actually do on a single charge, because I'm not an engineer/physicist, but it certainly fulfills my basic needs for modern usb-powered devices.3. How to use it. Okay, so the one thing that it didn't come with (which I sort of think it should) is an AC-to-USB power converter. That said, maybe Anker is trying to appeal to the international market by not including such a device. Plus, who doesn't have a dozen devices in their homes with USB ports at this point? Anyway, you plug the USB-Micro end of the cord into the Anker, and then the other end goes into a USB port on a computer or charger brick. Then you let it charge until the LED light on the Anker turns from yellow to off. Then, when you want to charge a device, you change the plug so that the USB-Micro end plugs into the device you want to charge, and the other end of the USB cable plugs into the Anker. (Note: this means that you can charge the Anker only with a USB-Micro cable, but you can use any USB cable to charge a device, though I haven't tried anything other than my smartphone). Now, once you have plugged in the device, you have to press the little button on the Anker! I cursed Anker's hearts the first time I tried to use this thing, because I didn't read the instruction manual and thought I had been swindled. Nope, I'm just kind of dumb. I pressed the button and VOILA! It started charging. I keep meaning to see if the Anker will power my usb-powered speakers, because that would be really neat. I haven't tried it yet, though.4. Aesthetics. This seems silly, I know, but I really like the look and feel of this battery pack. No joke, it's just kind of satisfying how it looks and feels. I can't put my finger on it. Sometimes, I just like using electronic devices. This is one of those times. II'd recommend the Anker mini battery packs to anyone who wants to carry around a little extra juice. You'll probably get a charge, maybe a charge and a half (depending on your smartphone make and model) out of it. For this price point, you can probably get two, if you're really worried about it.

This is my first review and it's because I seriously like this product. The quality and functionality of the PowerCore plus mini is only exceeded by its bargain price. I'm not new to Anker products, they always seem to live up to or surpass my expectations. This little guy is no different. I get at least 2 full charges on my iPhone 5s from the charger from 5% or so to 100%. I take it in my bag or in the car and plug in to get me back up to a full charge on the go. I'm not tethered to a wall/car charger and get a charge just as fast as if I was. It intelligently charges your device as fast as your device allows which is great because over charging or rapid charging batteries can seriously shorten their lifespan.The size of the charger is a cylindrical tube 3.75 inches long by 0.8 inches in diameter. It has an aluminum body that feels robust and well-made. It's coated with a matte black powder coat finish. My unit came with a black mesh bag w/drawstring and a USB to micro-USB 24 inch long (23.5 inch of useable length) charging cable. The mini charger has a micro USB input port and a regular USB output port. Just push the LED status button to see Green (50-100%) indicator light, Yellow (25-49%), or Red (below 24%) to see the level of charge of the unit or to activate the unit to send power to the device you want to charge. The indicator light stays on and shows its capacity of charge remaining while charging. It's very easy to understand and use.The mini is small and light weight enough that I've taken it camping/backpacking too. I plug it into wall power before I leave and I'm good for a full charge anywhere in the field when I need it. I've got a rechargeable headlamp that plugs right into the USB of the mini and charges during the day inside my pack when I'm not using it. Same for my GPS, I plug its cable in to the mini charger and it lights right up for use- any power that isn't running the GPS gets funneled back to the NiMH batteries in it and it slowly charges. This is a great feeling to know that I'm not going to run out of battery power on the devices I need and use daily whether in the field or around the city. I recharge my PowerCore plus mini with the dual port Anker PowerPort Solar 21W solar charger at the same time as my phone if I'm out for a couple days or more which lets me recharge at night or on the move. I've begun researching the 800 mile Arizona Trail that spans the North/South distance of my state from Mexico to Utah and will be using a battery powered personal satellite transmitter to let my family and friends track my position via the web and let's me have access to emergency responders if I get into a life and death situation. All these devices would require literally pounds worth of spare batteries where this system mere ounces. The fact that I can keep power to all my stuff when I might be days away from civilization is amazing but even more incredible when I can do it with a lightweight, affordable, and reliable piece of gear like the PowerCore Plus Mini. Maybe power in the field isn't important to you but tell me your phone has never run out when you need it most! I know mine has. This gives that peace of mind that is well worth $10.I'm considering upgrading to the Anker 5000mAh version portable charger to go further between charges but have been more than impressed by the quality/ease of use to price ratio of the Anker PowerCore plus mini. I highly recommend it, you will use it often and I don't want to be caught without it. Thanks Anker for making great, reliable, high quality, and affordable products! Keep it up and I'm a customer for life.

With the way I use my portable devices for personal and business use, I feel like I'm becoming a connoisseur of external battery packs. Since phones these days rarely allow for replaceable batteries, external packs are the best way to give your phone or tablet a much-needed bump in the middle of the day or evening.My main go-to pack is a PowerGen 8400mAh pack, which has worked wonders but is very bulky and heavy. It's great to throw in a bookbag or my wife's purse when I'm with her, but for everyday use when I don't carry a bag with me it just isn't feasible. For that, I originally looked at the Motorola P2000 which is a small, plastic device with a relatively tiny charge. It worked well and had a built-in cable which I thought I'd prefer, but overall I realized I liked having a longer cable and something that wasn't rectangular (so I could fit in the same pocket as a wallet or my phone).Based on the reviews, I ordered the Anker Astro Mini 3200mAh in black. I received the product the next day and it turned out to be a great device. The size is smaller than anticipated, which is a good thing. It easily fits in the back pocket of a pair of jeans without it showing, which is next to my wallet and with a USB cable plugged into it. It's a little heavier than I expected, however I really think that's due to the nice metal that the pack is made of. This really feels durable and sturdy in the hand and much better than my previous Motorola P2000.The Astro Mini came with a charge but I wanted to make sure it was full, so I plugged it in and charged it all the way which seemed to take quite a while (3+ hours). After it was fully charged, I unplugged it and gave it its first test run on my phone. It worked well, charging the phone quickly and gave me no problems. The only slightly worrying thing I noticed was that the battery pack seemed to get pretty warm while charging my phone, but I've read that about other Anker products so it may be nothing to get concerned over.One note is that it only discharges at 1A, so you probably wouldn't be able to use this to charge an iPad or Android tablet. That being said, tablets probably have more juice than this can provide anyway so this is probably designed with phones in mind.Although I really do like this pack, there are some slight changes I would make. One is the LED light - while charging itself, it's yellow until fully charged and then it goes out to signal that it's done. While discharging, it remains green to show there still is charge left - no matter how little there may be. I would have liked to see different colored lights to signal how much charge left - for example, green for 100-75% charge, yellow for 75-50%, orange for 50-25%, and red for 25-1%. That way I could know how much charge is remaining in the pack without it being a guessing game.Also, a little cable management would be nice. I use the standard black USB cable that came with this that looks to be around 3-4ft. Since I throw it in my pocket, I don't want the cable getting tangled or out of control and unfortunately there's nothing on the Astro Mini itself to prevent that. I solved this problem with my standard phone cable management device, my wife's hair-ties - it's not pretty but it works. I would have liked to see a small clip on the side of the Astro Mini that could have served two purposes: 1) to help secure the cable when not in use, and 2) to act as a belt or pocket clip in case you need it. I know the device comes with a mesh bag, but the way I plan to carry this means I won't have enough room to use that.Ultimately though, I really like this pack and I'm going to use it for quite a while. It's a great mix of form and function and it's small enough that you can carry around daily without it overburdening you. Small quibbles aside, I'd recommend this to anyone whose phone needs a quick bump of juice throughout the day.Pros:- Smaller than anticipated- Well constructed- Charges phones quickly- Looks stylish with many different colors availableCons:- Gets warm while charging devices- Charging itself from the wall can take a while- Could use a clip for cable management or to hook it on a belt, pocket, etc- LED light could be tweaked to change colors based on charge level

I thought it about time to finally write a review about an Anker product. I am so impressed with this company and I hope that this may help others choose what I believe are the best products on the market. Over the past 3 years i have purchased multiple products form Anker. I don't remember how I first heard of the company or decided to buy/try the product, but I do remember it was a portable battery charger. If I remember correctly, it was one of the Astro products. I remember being so impressed with the charger that When I needed a specific product, I would look to see if Anker produced and sold it. Over the past 3 years I've purchased the following products. One 24W Dual Port rapid charger, four 40w family chargers, four 3 feet lightning cables, two 2nd generation Astro 3 chargers, 2 slim she'll 6s plus case protectors, 11 tempered glass protectors for various Iphones, 2 power core plus mini's, 10 6' lightning connectors, power line micro usb 5 pack, 2 CD slot car mounts and a premium aux audio cable.You must be thinking " what the heck is this guy doing with 10 of this or 6 of that. Every product I've listed, I bought and was so impressed with every aspect from the packaging to performance of the product that I have started giving them away as birthday and Christmas presents. For example , the CD slot car mount was the best mount I've ever purchased and believe me when I say " I've owned at least 10 mounts over the years" and they are all garbage when compared to the Anker mount. I had to have one for each vehicle. If you do not use you CD tray in your car to play CD's then this is the best phone mount you can buy.I've had a couple of problems with the 40W family chargers. 2 of the original chargers had a couple of the ports stop working. I called the Anker support line and all I can say is the customer service is a 15 on a scale of 1 to 10. They sent me a replacement product and no questions were asked. It was just done. I've had no further problems with the chargers and my children all have a 5 port charger as well as one behind the couch. One plug, one charger, 5 ports, 5 lightning cables and I have no more complaining children!!!I started this review to specifically talk about the PowerCore+ Mini. I received the product yesterday and was satisfied with the packaging. It was not what I am accustomed to with Anker products, but it was ok. If you buy an Apple product you will understand what I mean when I say "the packaging is as beautiful as the item inside" and you know the company has put tremendous effort into the small details. Anker is by no means on par with Apple but they are one of the BEST I've come across. The packaging was ok, but I have to mention that the thought did cross my mind that it could have been done a little better. I unboxed the mini and what I found inside was exactly what I expected. A beautifully crafted product that looks just as good as anything Apple might produce. I was very impressed with the aluminum body and the front layout with the led button. My second thought was " once USB Type- C becomes widely adopted and you have only one small connector on the front for charging and loading, this will be a slam dunk. I thought to myself, " If Anker would adopt the Type-C interface on this product, they could likely increase the battery size another 20 to 30%. Needless to say, I was impressed. I plugged the unit in and let it fully charge overnight.As you see in the list above, I have a couple of the larger Astro 3 chargers and I get multiple charges of my iPhone with those larger units. I'm thinking to myself, " what can this tiny thing do"? I decided that I would carry the charger with me all day and finally plug it into my phone after the battery goes dead. Now this was not as easy as you think it may be. I have the new iPhone 6s Plus with a 2750 mah battery and that thing last all day. I've had the phone 3 weeks now and I've never had the battery go dead on me. I've been close a few times, but never needed to hook it up to my Astro 3 for a boost. Driving out of Manhattan today I had my phone running 3 GPS navigation programs and had you tube playing videos all just to kill the battery. I finally noticed that the phone was dead and at exactly 7:00pm I plugged the Mini into the iPhone . 1 hour later It was at 33% and the light changed to yellow. At 1 hour 35 minutes I checked and it was at 49%. At 2 hours the light started blinking red and my phone was at 78%. I did turn on airplane mode as soon as the phone powered up. I wanted to get an idea of what the battery could do and be able for others to repeat the process under the same conditions. In my opinion, the only way to get close to this is to activate airplane mode for the duration of the loading.I was amazed at how far this tiny lipstick charger performed. I believe this is the perfect charger to carry all day just in case you need a boost. I would never replace my Astro chargers but this is the perfect compliment to my collection. :)Summery: This is the perfect product to grab when heading to the supermarket and realizing your phone is at 3%. With the mini, you have a product that can solve the "going out to dinner" and realizing your phone is almost dead problem. I would not carry this on the all day hiking trip where I know my phone GPS will be gobbling up power and I may not be home till late at night. I would have my trusty Astro 3 in my backpack. I am sure I will be using this charger almost every day!!

I must preface my review of this product by explaining my purpose in purchasing it. After traveling to Asia for over 50 years, I can no longer carry tons of luggage. In celebration of my seniority of 70 years, I am making my next two-month trip with just a small Marmot backpack and an Eagle Creek Load Hauler Expandable duffel. Both packs qualify as carry-ons, which also means no waiting at baggage carousels and no lost bags!Packing weight and compactness is my primary motivation for anything I take on the next trip. I have a three-year-old Anker Astro E7 26,800 mAh charger, which works great but weighs a tenth of an ounce under one pound. One extra pound is too much for this trip, so I chose the Anker PowerCore+ Mini 3350 mAh lipstick charger, which weighs around three ounces.I started charging my iPhone X at 9 AM, which was indicating the handset was down to 14% charge. I used a genuine Apple USB - Lightning cable. Two hours later, the iPhone X was up to 86% charge and the PowerCore+ went from solid red lights to flashing red lights, indicating the PowerCore+ was about dead at 5%. At 11:03 AM the PowerCore+ Mini 3350 indicator lights stopped, indicating that charging had stopped. The PowerCore+ Mini 3350 was depleted and the iPhone X was at 89% charge. By my calculations, the PowerCore+ Mini 3350 was overrated by a considerable amount of power. I only got 2,417 mAh of power from an Anker product rated at 3,350 mAh! Hmmm, 75% charge. This was only the second full charge on the phone X and the first time the PowerCore+ Mini 3350 was used to charge anything.But wait! Perhaps my test was flawed. Is it possible from the time the PowerCore+ Mini 3350 was manufactured, initially charged and shipped, it had lost considerable power before I used it? Did the manufacturer fully charge the PowerCore+ ? I pulled out my iPhone 6S Plus that has a battery rating of 2,915 mAh. After charging my PowerCore+ Mini 3350 back up to 100%, I then connected it to the iPhone 6S Plus at 4:13 PM. Two hours later, at 6:15 PM the handset was at 88% charge, and the indicator light on the PowerCore+ was still yellow. 6:29 PM 91%. 6:46 PM 94%. At 7:01 PM, the red indicator light on the PowerCore+ came on with the charge on the iPhone 6S Plus registering 96%. At 7:45 PM, the handset was fully charged. About the same time, the PowerCore+ red light turned off, indicating its internal battery was depleted. I think I can say that you will get at least one full charge from a handset that has at least 14% charge left.More important, many people on Amazon ​and other sites leave poor reviews based on flawed testing. I was looking for a charger that would provide me with one full charge after my handset’s battery was almost depleted. The PowerCore+ delivered, so it gets full marks. Lessons learned; pack light and fully charge!

UPDATE: I bought 5 more of these little things to give to some of my friends, and recently one of them was going down the freeway on his bullet bike at about 75 MPH and had the charger I gave him fall out of his coat pocket and bounce and roll down the road. He looped back and spent about 10 minutes looking for it, found it in fully functional condition with only a few deep scratches on the paint. I’ve used and abused my chargers here and there, but nothing like this. Bravo to Anker for making some durable products!I have over 10 Anker portable chargers ranging back to some of their first product to their newest. They are all in the range of 15,000 to 27,000 mAh. I wanted something small that would be easy to pack around, so I looked into Anker’s options first.I came across this PowerCore 5,000 and the previous PowerCore 3,350, both for pretty much the same price, so I bought both for a comparison in size and power. I was more looking for something to keep comfortably in my pocket for when I need it the most.The powercore 5,000:This device is about as thick as a United States 50 cent piece and a bit shorter than a soda can. It holds about 2 charges for my iPhone X and charges it pretty quickly in comparison to a standard wall charger. I think the size of this one is a little big for the convenience of putting it in your pocket, but it would be nice for keeping in my car for that extra charge on the go.The powercore 3,350:This charger makes the difference in size with its thickness. It is between the thickness of a nickle and a quarter, but is only half an inch shorter than the powercore 5000. The 3,350 mAh can charge my iPhone X once from completely dead, which is about what I need from something this small. A big note is its 1 amp output, that charges as fast as a standard iPhone wall charger. It fits comfortably in my pocket which is exactly what I’m looking for in this.What to buy:The newer PowerCore 5000 is better in just about every way except size, it can charge more, it can charge faster, it even has 3 charge indicators to tell you how much charger is left. For the same price, you really can’t argue with that.The reason I’d stick with the PowerCore 3350 is just it’s size. You can slip it into your pocket easily and its just all around more convenient.They both have a quality, sturdy feeling build. The PowerCore 3350 has a more white-ish top which for most people isn’t a big problem.

*** Update #2 ***No change in rating but I do want to offer a few points of clarification. Anker reached out to me regarding my review and offered a clarification and a chance to review another of their products. First the clarification: the Anker PowerCore + mini is a 1A device, whereas the RAVPower 3350 is a 2.4A device. Therefore, it makes sense that the RAVPower will offer the benefits discussed below. However, my review was based upon similar sized and priced devices and comparing the two I would still recommend the RAVPower over this Anker device.However, I don't recommend either now. Anker also provided me a free device, the Anker Astro E1 6700mAh ([Upgraded to 6700mAh] Anker Astro E1 Candy-Bar Sized Ultra Compact Portable Charger, External Battery Power Bank, with High-Speed Charging PowerIQ Technology (Black)). It is similarly priced (slightly higher price, but in the same range) and similarly sized (slightly larger, but in the same range) and offers more charge (6700 vs. 3350). The trade-off on price and size charge are worth it. Also, the Anker E1 does not get hot, even during fast charge. I really liked the E1 device and recommend that device over both the RAVPower and Powercore+ mini.*** Updated #1 ***Dropping to 3 star (from 5 star) after using the RAVPower Luster Mini 3350mA (RAVPower Luster Mini 3350mAh Portable Charger External Battery Pack Battery Bank Most Compact Power Bank with iSmart 2.0 Technology (2.4A Output, 2A Input) for Smartphones and More (Black). The RAV has more capacity (effectively) and a much faster power charge (with very similar heat generated). No downside to the RAV as compared to the Anker.*** Original Review ***I purchased the Anker power bank for a recent trip. My aging phone has been overheating and burning through battery life and needed to have back-up power for my trip through various amusement parks. The Anker worked great in providing daily charge to my phone. No overheating (wish I could say that for the phone) and still provided very fast recharging. It was a great, small profile. At times I forgot I had it in my pocket.

Well, hard to know what brought you to this item, but assume it to be a wall charger for your device without the wall :-). It isn't simply like an extra battery or battery pack (although it could do that too), it is designed as a portable battery charger. Right now I use my Android phone for two serious power hungry applications. Both applications require GPS, Bluetooth and WiFi to be enabled all the time. One is a Golf app (GolfPadGPS) that gives you every geo function imaginable from distance to pin to Google Maps of the hole, including location, club and distance of every shot hit to a database recording everything forever. The other app is a Garmin GPS for flying airplanes and it communicates, GPS, Bluetooth and wireless and talks to several connected devices from music, to tower audio to WASS GPS and ADS-B connectivity. They all use a lot of power and my Android note has an 1600 ma battery. That makes this last about 2 hours and it dies. I can do a lot with the gold app by turning off functions, but it's still hard to get 4-5 hours of "on" time. When I get the "Battery low, plug device into a charger" warning, I plug this in, push the on button and everything goes back to full power *AND* it has enough juice left over to recharge my device. I can usually finish my flight or my round of gold and have a 100% recharged phone. It provides twice the power of my phone battery and can discharge at a very high rate, which is why it can charge my phone while running everything on board. It's light, easy to use and appear fairly rugged. I added a Velcro strip to keep it attached to my phone when in use, but it comes with a little carry bag, cable that can be used for charging it and discharging to a phone. As a guess, I'd say I can get eight or nine hours of high energy usage. I have not tried watching high def movies with it, but I am 100% certain you could watch 2 3-hour hi def movies during a flight. If you were going to be downloading them wirelessly while watching, I'm certain you could watch at least 2 2-hour movies and probably three, but that's nine hours at full power with wireless and video and that may use up more than this device offers. The good news is you could have two with you if you were doing overseas flights that required 9-12 hours of video time. Excellent product, excellent service.

I had recently purchased a new Blackberry Z10 after years of having an older Blackberry. I loved the features, big screen and apps. However, with the big bright screen, tonnes of apps, Bluetooth, Wifi etc... I found my phone battery almost depleted by mid afternoon. Then I came across the Anker Astro Mini and it was the solution to my problems.The Astro Mini is a portable power source which can be used to charge a wide variety of different devices. The best thing about it, is the size. It truly is the size of my wife's lipstick. So that makes it extremely portable. The device feels solid, not flimsy like other external power sources. It has an all metal design and feels like it could take a beating. To charge the device is simple - just plug it into any micro USB travel adapter (which is not included, but for $25 who cares). It takes 4-5 hours to fully charge and keeps its charge. It contains 2600 mAh which is enough for one full charge (while the phone is still on) of my smart phone. It comes with a cable that has a variety of adapters which can plug into either an iPhone (sorry no iphone 5 adapter with this model), Blackberry or Android phone. While it is charging the device (which is the same time as a travel charger - for me 5 hours from a completely depleted battery), you can still use your phone. It is very simple to use. After getting this product, I bought a few more for family and friends.Overall this is a great product. Well made, reliable, and best of all... reasonably priced. I must say, someone at Anker was thinking when they came up with this product. Highly recommend this product to all individuals with smartphones and are heavy users!Excellent, excellent, excellent.

Mi madre necesitaba la bateria, así que decidí regalarsela. Carga mi Galaxy S6 hasta el 80% aproximadamente, su galaxy S7+ aproximadamente igual. El unico inconveniente es que tarda mucho en cargarse y que no tiene fastcharge al momento de conectarle el celular. La salida es de 1.0A así que tengan eso en cuenta también.

La batería cumple con creces lo que promete. Los materiales de construcción son durables y bonitos. La mayor parte está construida en aluminio, sólo la entrada de las conexiones es de plástico, pero de excelente calidad.La capacidad de carga es exactamente cómo se describe y en resumen es una excelente compra, la recomiendo ampliamente.

I would recommend this product to anyone with a device with a 3,000 mAh or smaller capacity battery that wants an inexpensive and compact charger. Please keep this capacity in mind. Even as a tech geek/nerd, I didn't understand mAh was a measurement of capacity that in laymans terms could be compared to litres.This will push a MAXIMUM of 3,000 mAh to your device(s), but it will do so 1,000 mAh (note that through use, the overall capacity will slowly degrade) at a time. If you want something where you can just plug it in and have peace of mind knowing it IS running, you may want to look elsewhere.However, if you see the appeal in something that that operates in smaller, user-initiated bursts, this may be for you. While I get smaller individual charges (I can still use the entire charger battery if I want to, just requires I check on it periodically to see if the previous cycle finished), I rarely need to use all three that this product contains, meaning less charge/discharge cycles. In laymans terms: The lessened, but arguably more reasonable use I get through the bursts will likely prolong the lifespan of my purchase. Less cycles = less degradation of the internal power cell.For reference, the Samsung Galaxy S4 uses a 2,600 mAh battery. iPhone batteries have ranged from 1,150 mAh to 1,570 mAh over the years. The Motorola Droid Maxx, a device that has the Maxx added to its name for battery capacity more than anything, has a battery rated at 3,500 mAh.Oh, and the construction is sturdy and solid. It's unnecessary for something like this, but it is appreciated.

Works really well in charging my iPhone 4S! Came right on time as well. So far I haven't had any problems with the product. Comes with a small pouch to put everything in. In the tittle when it says that the apple adapter is not included it means the adapter you plug into the wall and not actually the part that you plug your phone. I got a little worried after I purchased it cause I thought the cable would only have a USB end and a micro USB. Only the iPhone 5 has the micro USB to charge but iPhone 4S is different. I was glad to know that it did come with the tip to charge an iPhone 4S as well. It charges my phone really well and fast however I find that the days it's fully charge but don't even use it the battery still gets drained a little. Other than that it's an amazing product and really useful as you never know when you can find an outlet.
