    Очень полезный кейс для резервного питания гаджетов с USB-разъемами. Я использовал АА аккумуляторы, получая на выходе банка 4,8 в, чего вполне достаточно, чтобы в походных условиях зарядить телефон или другое устройство.

    Pros: good connection & charge good price Cons: for charging phones need an adapter for DC (1A Lithium Battery Charging Module - Blue) OtherThoughts: Bottomline: good for emergency charging for anderstanding people

    Pros: the only thing that comes to my mind is on-off switch Cons: expensive for what you get - this is just ordinary 4 AA bank - no power regulation whatsoever - I would expect better product for almost $5 - I can build such box myself for less than $4 from locally sourced materials. I will have... Read more

    This product is simple to handle - put in 4 rechargeable batteries (2500 mah) hooked up to the tablet and ASUS tablet and (i was very pleased) it was charged in 2 hours completely. There is a turn off button and it's very conveniently to turn off the device It is a pity that the price is a little... Read more

    The best solution for this money. Packaging has been opened. The battery cover is not held, it is assumed there is no screw. On the device, there is no indicator of the charging process - just switch. Charge the phone and Samsung b2100 Sony Xperia Acro S. Charging the battery life of mobile comes... Read more

    This piece is cheap. Maybe useful. Quality is good enough for it's price. It charges my Kodak PlaySport Camera and my Mp3 Player also works well with it. Unfortunately it doesn't charge my android smartphone Motorola XT535 via micro-usb. Maybe not enough stream for it to detect source? I don't :(... Read more

    there is an on off switch so that is good and the springs are nice, the usb connector was bent on mine but it was eaisly fixed and now is working and can be used. the cover does not snap securely closed so the lid is prone to sliding open occasionally, just keep a rubber band around it to keep it...

    Very useful in case of emergency when you don't have a nearly source of power. For example, in my case, when going outdoors to the mountain using my mobile device as a GPS and running out of battery. This tool saves me of being out of communications in an emergency. It is not the same power as a... Read more

    Good size for traveling. Cheap product to charge different electronics with connection to USB. Not charging with ordinary alkaline batteries (duracel). I used philips rechargeable batteries 2100 mAh and connect to my HTC Desire smartphone. They just charge it about 40 percent, and then began to 0... Read more

    I have earlier bought this unit for myself and works fine. The unit works as designed with 4 pcs AA batteries which is the best part of this product. AA batteries are readily available in every shops where battery is sold, both local and overseas. There is a on/off switch at the corner. Initially... Read more
