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
-Charges fast, somehow even faster than my original charger even trough its 1A.
-It doesn't get hot.
+Bonus point! They include a "universal" cable and a lot "head" to it -It's not fully 20.000Mah it's around 16.000Mah I think.
-I only used the microUSB head but when ... 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.

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

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'... Read more
