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, some for devices that are really obsolete so ... 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 i pulled out from my pocket the connector falled ... 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 on the package are a terrible version of English.... 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, very happy with this buy. Its great for trips and ... 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 1.5 times the size of my other bank. Not sure ...

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 are lower than reported. Device claims to have 200... 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 too bright, seriously, its bright enough to force ... 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've had it unexpectedly go dead on me from three dots.... Read more
It is build quite well, doesn't feel like it's made up cheap plastic. - Comes with multiple adapters so you can charge various devices - good for phones and also tablets, can charge two devices at the same time, good price too! It's a bit heavy, but can't expect a battery to hold a large charge without having a good amount of weight to it, and it doesn'... Read more
