Anker Power Bank, 20,000mAh with Built-in USB-C Cable, 87W Max Fast Charging (PowerCore 20K for Laptop) Lenovo, HP, Dell, Microsoft, MacBook, iPad, iPhone, Apple Watches, Samsung and More - Black

Sturdy build and strongly wired. Worked for international use back then. Works perfectly for laptop charging (I am using it for my office HP laptop). Digital indicator is very helpful and appears accurate to me. It's is one of the premium powerbank with Power delivery and deserves the price it commands. This review is after 6 months of use.

Love this powerbank. An absolute beast with quick charging. In built-in cable and overall built quality is fine. Slightly on heavier side but that's fine.

Used it only once. Seems to be a good product. Need multiple usage to give a realistic evaluation. Hence the 4 star rating.

It works as advertised. Build quality is good and it is able to charge both my phone and laptop at 65W. It also charges back at very fast speed.

While the power bank took only 1-1.5 to charge from 0 to 100% which is good. But it's performance is the main concern. It claimed to charge macbook 1.2 times and mobile like s23 ultra 3 times. Which is wrong:- Test1- Laptop Case1:- When i was using my laptop(with battery currently being 22% and laptop was being used simultaneously) it reached 87% and the power Bank completely drained from 100 to 0. Failed 👎👎 Case 2:- when i charged my laptop again when it was in use . It was at 25% , but this time the power bank charged it completely to 100% and the powerbank drained from 100 to 0. Failed 👎👎 Case 3:- when the laptop was closed (sleep mode) it charged my laptop from 6 to 100 within 2 hours but the battery remaining only 7 percent on the power bank. So it can't charge 1.2 times. Failed 👎👎 Case 4:- again i ran this test, and now it drained completly under the same conditions. Failed 👎👎 My laptop is lenovo ideapad 5 which has smaller battery than the macbook advertised by the company. So the powerbank should charge it more than 1 times. But in 1 time only, it is completely drained and leaving only 7% So you can see the inefficiency Note:- same apps ,same brightness levels was being used to test the product. Test 2:- Mobile Case 1:- it took 8.5 hours to charge my moto g54 from 0 to 100 and in this time range the power bank drained 45%. The efficient capacity of any Powerbank is 80 to 85% meaning that the actual capacity of any company's powerbank will be less than advertised. So if i consider 85 percent of efficiency then the power bank has 17000 mah. My phone has 6000mah of battery . So 45 percent of 17000 is 7650 mah. Meaning it took 1650 mah more to charge my mobile and it took 8 hours which is very long. Note:- This mobile supports 33 watt fast charging and it takes only 2 hours to charge it from the stock charger provided by the company. So in this case it is failed 👎👎 Case 2:- Moto edge 50 fusion I charged my mobile from 0 to 100 and it took 50 percent of the power bank's battery. Which is the highest drain i have noticed till now in any power bank. So 50% of 17000 is 8500. It took 3500 mah more than my phones actual capacity which means that something is wrong with the internals of this power bank. Again ran the same test, now it took 45 percent. While in this case it took only 1.5 hours to completely charge my device which is a thumbs up 👍 Note:- My mobile has 68 watt fast charging and it has 5000 mah of battery. It takes only 1.2-1.5 hours to charge my device from the stock charger provided by the company. So the efficiency of this power bank is very poor. In this case also failed 👎👎 While i have used many anker products in the past, some of them like my soundcore life note purchased in 2020 is still working fabulously and it is now also providing me 8 hours of playback time. But i cant recommend this powerbank.👎 Thank you for reading the post. As no one on yt is talking in this detail about this power bank

Amazing power bank, fast charges mobiles. Best part is the tucked in charging cable, (you don't have to hunt for one). A bit heavy but I keep it i my car so not an issue.

Overall good but the inbuilt cable not working properly but power bank speed & power lasting is awesome

A large capacity (20,000 mAh) Power Bank is an excellent (2nd) buy for me. It meets my charging requirement of outdoor/in travel use of my 17" laptop, two cell phones, and a mini fan. 87 W power is more than adequate. Does not heat up at all. I found it to be quite sturdy and handy. It has a long backup after a full charge, a really fast charger at that. A short charging cable with a USB-C connector reduces line losses.
