Extremely useful device. I ordered three more such batteries for me and friends. 2.1 A output through the phone often charges more quickly than in the original charger. If you often have trouble with this phone / tablet (for example Samsung Galaxy S III/S IV ;) ) you left without the battery it is your ... Read more
I'm using this charger over the year and can say: battery is very good. Mostly chineese goods with rechargeble batteries are weak, cannot work for many charging cycles. This one is long-life battery, capacity didn't fall after the long use. I noticed that this battery cannot charge Samsung Galaxy Tab.... Read more

Can charge my iPhone 2-3 times. Haven't measured or calculated the actual capacity but it's probably not that far from the promised. The device is relatively lightweight for its capacity, I always keep it in my backpack. Despite being plastic, it looks kind of stylish as well, unlike some rivals. Once ... Read more
Looks nice, many types of connectors, it works. Not so heavy, I can easily carry it in pocket with me. Stays charged for a very long time. Capacity is lower than 6600mAh. I hardly charge two times my 2000mAh cell phone. So i think it is somewhere about 4000mAh. Overall useful battery. Both outputs 1A ... Read more
Light, good design, solid (well built), works! It is sold as 6600mAh. IT IS NOT!!!! Not even close to it. Indeed, I order to test I first fully charged the PowerBank (left 24 hrs charging). Then I charged my Galaxy Note (3.2 mAh battery) with the PorwerBank. First charge, OK (100%), Second charge, 10... Read more
- Good prce.
- it's has 2 inputs (one is supposedly stronger 2.1A and 1A).
- quite solid. - It charges extremely slow, slower than a regular charger, slower than charging via USB.

Simple and lightweight, it is easy to use and gives no problems when the battery recharges Some cables and connectors are very weak, the connection to the device is sometimes not as good as it should and the cable connection to the head is also weak. To recharge batteries on a table is fine, but moving ... Read more

Who knows in what condition battery really is. USB cable is almost useless. It is to short. The included adapters feels ... Read more
