Nitecore UM20 USB Battery Charger

The new Nitecore UM series makes charging more versitile and intuitive than ever before.  UM chargers feature a charging bay that will accomodate 18650s and a host of other li-ion and IMR rechargeables,  USB output to and microUSB input for plugging the charger to any USB wall charger or even a laptop, and a smart regulatory system that adjusts based on power input and is able to charge a battery and a device simultaneously!  Naturally, as with all Nitecore chargers, the UM10 and UM20 provide a full spectrum of battery protections, including automatic cutoff on fully charged batteries, reverse polarity protection, and OV battery activation.  A backlit LCD display lets you know the charge level of your battery(ies).

Another great feature of the UM line is it's small form factor.  Both the UM 10 and 20 have wrap storage for their USB cables, and they're both small enough to take and use anywhere.  And when you're on the go and need to get your 18650 battery and device charged but have an insufficient power source for simultaneous charging, you can hook both up to the UM10 and 20 and specify which it should charge first.
