UltraFire WF-139 18650/CR123A/14500 Battery Charger Description

How to use?

Insert one or two 3.7V batteries to charge. Since the device has two isolated channels, you can simultaneously charge two batteries with different capacities.

* Note: although CR123A batteries can be charged by this unit, a spacer is required to insert CR2 batteries into the slots and this spacer is not included in this package.

An official ultrafire spacer will become available soon as an add-on. In the meantime, you may bend a paper clip to charge CR2 batteries.


Awesome charger that charges everything (except for RCR123A, which requires spacers). Charging voltage is between 4.16V and 4.17V tested (when charging single 14500 cell). Built quality is awesome with speedy charging 450mA performance. This charger is safe to use with protected or non-protected rechargeable li-ion cell.

Quite a money saver Review by firewarrior1705
This charger is very, very cheap. If you use 18650 batteries in your lights, this will save you a ton of money . (Posted on 6/4/13)
urchased As A Backup To A Similar Looking Trustfire, And Works Just As Well Review by MJNC367
As stated above, I bought this as a backup to a trustfire charger which has been very reliable. This ultrafire is proving just as reliable. They are similar in many ways. The LED's start out red and turn green when the charge is complete. (Posted on 5/24/13)
