One of My Favourites!
This is one of my favourite power banks. I love that all the cables are attached, so I don’t need to worry about fiddling around or carrying extra cords, it’s super convenient and hassle-free. It’s really powerful, and once fully charged it lasts a long time, easily getting me through multiple charges. It’s a bit on the bulky side, but honestly I don’t mind because the performance and convenience more than make up for it. Overall, a great power bank that I’d happily recommend.

Excellent
Excellent power bank. The built-in cables are very convenient and save carrying extras. Fast charging works well, and the 20,000mAh capacity easily gives multiple full charges. Solid build and clear battery display. Highly recommended. So good i bought another !

Great and integrated charging solution
Great battery bank with integrated leads. Was a bit worried about size and weight, but in practice this is just slightly more than my (full size) IPhone in its wallet case. Having all the leads built in was a key feature as having them in place avoids the mess created by having a rats nest to pack. Obviously there is a longer term risk of damage, but the separate sockets should avoid the worst of this. The only real reason to loose a star was that the recharge is very slow ( 6 hours). Given it is a PD connection then it could be a fraction of this. I have not done a load test, but it seems to be able to charge iPhone and iwatch with no problem (at the same time). On my brief tests it also appears to be able to charge at least some devices when being charged itself. Thus becomes important when you consider some of the charging options only claim 18 hour recharge time… So, a good travel option, as a single charger (without leads) would charge the battery, which could then maintain all the other bits and bobs (as long as an Iwatch base is also along for the ride. Much less messy than the alternatives

Impressive & fast charger
Holds a charge for a long time & doesn't take long to charge up my laptop or phone. I use it when I have a full day out & about, & having various charging connector types is a great help. I have found this to be a really good purchase for a very reasonable price.

Smart design, well executed
Really smart design, really well executed. The charge capacity is really good, it kept my phone charged over a weekend camping trip. The individual leads are very durable and it’s neatly tucked away in a compact little box.

Nice powerbank
Not to heavy and can use phone while recharging Six charges from 40% per full powerbank charge and powerbank takes quite a long time to recharge I just do this overnight Very useful having all the wires attached

This power bank is very powerful and chages all you usb devices extremely fast. The built in cables with different usb connectors makes it very handy. The only inconvenience is that it is a little heavy but given the power it carries, I still have it with me everydsy in my bag. FIVE STARS!

Excellent, excellent et encore excellent ! J'adore cette batterie. Pour quelques explications, elle se charge assez lentement, j'en convient mais elle charge environ 3 portables voire un petit peu plus pour d'autres articles telles liseuse.. Les câbles sont certes petits, ce qui est logique, mais hyper pratiques. J'ai acheté 1 autre batterie comme celle-ci tellement j'en suis satisfait
