Pros: Charged my phone twice while on a camping trip and still has power left. Easy to store as quite a good size, and USB connection makes it compatible with any charging cable.Cons: Nothing I didn't like.

Pros: Kept my Galaxy S8 fully charged at a 5day music festival. (Higher than normal usage, cam, torch, full internet).Just unpacked it- 2/4 lights on power left indicator.Bit of a brick but it's well worth it.Stick a decent AC charger on it for its initial charge and its fully charged in just a few hours.Cons: Only improvement could be some kinda plug/protector to stop damp/grit entering the charger ports, but that's REALLY scratching around!

Pros: The portable charger has a few ports so you could charge multiple phones or iPads at the same time.Cons: The only reason I have not giving it full stars is it is very bulky and heavy and not something you want to carry around with you

Pros: Excellent product and really useful. Helped me a lot as i record videos using my phone.Cons: May be the charger cable length can be increased
Pros: So easy to use. Fast charging better than normal chargersCons: A little bit heavy but must be due to amount of batteries in case
Pros: I bought this the day before I was due to go trekking abroad in the mountains as my old one stopped working. It was very easy to use and kept my phone and watch charged all week. Excellent product and very good value for money.
Pros: Charges quickCons: Have to alternate which USB port to use each time which is annoying
Pros: Excellent capacity, ease of use and overall value.Cons: Quite weighty, but as expected for such a high capacity bank.
Pros: Does what it says & can charge two devices at onceCons: It's a lot heavier than I expected, although it is a higher capacity than I'm used to. It had enough for several charges & kept me in power for the duration of a festival, but didn't have the number of full charges suggested by the blurb
Pros: Light weight. Easy on the eye. Great price. Amazing battery life. Overall I love it!
