Brilliant device
This is a truly brilliant device. I bought the higher capacity one and am so pleased I did. It’s a manageable weight and seems to last forever! No loss of charge if not used and will fill an iPhone several times over - useful if you are taking loads of photos and using the battery up more quickly than usual. It’s incredibly quick to charge and the convenience of not needing separate leads is huge (it’s yet to be seen how well the built in leads last). I can walk around using my phone as it charges if needs be. Or sit over a coffee while it slurps up the juice for its battery. My daughter snaffled mine when visiting her far away so on return home I immediately bought myself another. I wouldn’t go anywhere without it now.

Excellent.
Very good power bank. Seems well made. Gets rid of need to carry multiple cables. It’s fairly slow to charge itself but it charges devices plugged into it quickly. Only thing that would make it better is if you could charge the power bank and use it charge devices at the same time but that functionality is not supported.

Cheap, but good quality
Not as good as Anker, seems to lose power over time, but a lot cheaper. Will definitely last a few years

Heavy but absolutely brilliant. Holds power at 100% for weeks - the fitted cables are great - all options covered. The colour is lovely and charging speed is as expected. Reliable and am really happy with this

Good product and well worth the money
Great power bank. Holds plenty of charge and has multiple outputs including USB-C PD and USB-A. Rugged construction but not overly heavy compared to some high capacity power banks. I have 2 of these and have purchased for other family members.

Good little power bank
Good little power bank. Have purchased for myself, and a couple of my family members and have not had any problems so far. Fastest power bank that I have ever had. It has a screen which tells you which percentage of power remaining which is helpful. Easy to use and has multiple different type of charges included, I have had to use 3 of them so far which I didn't think I would have to. I bought on sale, but I think full price at the time of review is also good value for money.

Handy cables attached means your not scrambling for cables
Really handy power bank. Great with cables included. Takes a while to charge itself but charges devices very quickly. A single charge on the power bank charged my phone from dead twice and my tablet.

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

I absolutely love this charger, and keep buying more of them. Having the cables built-in means that you just have everything you need in one unit, with no other cables, or sometimes not even a plug, needed. I even travelled abroad for a week, completely forgetting my laptop and phone charger, and managed to get by with just this. I plugged the USB-A input into the hotel USB-charging socket overnight, with the USB-C output plugged into my iPhone. Both were fully charged by the morning, and then I used it to keep my MacBook Air charged during meetings over the day. I wouldn’t recommend it, but, heck, it worked! It also was enough to keep my iPhone and my MacBook Air running over a full day at a conference, again with no other cables at all required. It just answers every use case you need it to. Plug it into your airplane charging socket to keep your phone charged? Done. Charge your laptop by USB-C? No problem. Charge your USB-C iPhone and kids’ Lightning iPad? Sure. The only thing it can’t do, is charge by plugging the USB-C cable into a charging socket as an *input*. There are more USB-C sockets in Ubers these days, and for these, you’ll need a cable.

Muito bom. Tem grande capacidade e ter os cabos incorporados dá muito jeito.
