excellent little charger
March 24, 2017
I was pleasantly surprised to receive this single battery charger. Lightweight and works great !.. I did have a BLONDE moment trying to figure out which port to use to charge with, but you plug it into your phone charger.
ProsPrice is great/lightweight/cool read out

Awesome buy!
February 23, 2016
This was an awesome buy it charged my 18650 3.7v li-ion battery to 95% in under 2 hours and it was the best charger I've ever bought. Unfortunately though it fell out of my pocket in my fiancées friends car and went between the seats and he didn't care to bother to find it so I don't have it anymore and I am very sad because it's such a great buy. It charges amazingly fast for a micro usb powered device and it has a cute little stand built in and when you fold the stand back into place you can wrap the charging cable around it. Also this is pretty cool you can actually leave a fully charged battery in the bay and then connect the USB end of the charging cord to the port under the stand and discharge the battery in the bay (like if you needed a charger for your phone or something. It's a very efficient piece of equipment and if I can save some more money up I'm going to get it again because it's so worth it.
ProsCharges fast and safely Has a built in stand Micro USB powered Lighted display screen with percentage Lots of compatible batteries Discharge port below stand
ConsI guess the only thing is that when it gets to about 95% it takes another hour to get to 100%

Used mostly for Vape batteries 18650 3000mAh. When voltage drops below 3.6V, charger flashes EE and will not charge.

The description seems to suggest that an external USB device can be charged BY a fully-charged Li-ion battery in this device: I don't believe the user manual documents that feature, however. Do any users have information about this?
1 Answer
Advanced Functions USB Output Charging 1. As illustrated, lift the rear panel and plug an USB cable to the charging port underneath. 2. Connect the other terminal of the USB cable with an external device that needs to be powered /recharged. A USB icon will start flashing on the LCD to indicate the UM10 is connected with a USB cable. After the device is fully charged, icon stops flashing and remains on constantly.
