Cons: um pouco pesado. Demora para carregar completamente. Saídas para 2a e 1a de alimentação. Possui botão que ... Read more

    I bought this before going for a long (2 week) motorcycle trip; it helped me recharge the phone, GPS, bluetooth headset and helmet camera during the trip whenever the batteries were depleted. Can recharge 2 devices at the same time and the capacity is very good. No cons so far. It comes with many adapters,... Read more

    Compact high capacity rechargeable battery that can be used with a wide range of devices that use 5V input power supply. IT should charge a mobile phone several times. The "20000mAh" in the name is misleading as the real capacity is lower,but this is disclosed in the description. The instructions ... Read more

    Battery lasts for ever, you can charge at least a couple smartphone and still have backup. Very heavy. Not really suitable for daily use. It would be nice if you could charge the battery with a micro usb and not a min usb plug. Would save the hassle of remembering to take the mini cable. All to All, ... Read more

    Nice design, and feels quite sturdy. Both power out ports are well labelled. Power in port is mini USB. Has a check button to check the remaining power in the bank. Very cheap compared to electronic shops over here. On the heavy and large side, but I suppose it is loaded with Li-on batteries. It is nearly ... Read more

    Looks good, easy to use and to charge (doesn't come with power outlet adapter), must connet to previously owned one or at a usb outlet, through a micro-usb cable (provided). Offers several options of device connectors, exception for the lightning apple devices. Actual current/amperage output options ... Read more

    Works great on all my devices, especially with the 2.1A port. Charges anything and everything with no issues. Love the fact that it automatically shuts off when you disconnect the device. And the capacity at least seems to be as high as advertised. Definitely lasts long enough for my needs. Light is ... Read more

    This thing holds a ton of power. I can charge my iPhone multiple times before the device needs charging. And it accepts a trickle charge; I used this in the woods with a GoalZero Nomad solar panel. The indicator lights are not reliable. It will read 4 dots for weeks and then suddenly read nothing. I'...
