Ultrafire wf-139 Lithium Ion battery charger 14500, 17500, 17670, 18500, 18650, 18670 (as low as) $13.95!

Lithium Ion battery charger with two independent charging channels and adjustable compartments. You can now safely charge two batteries of unequal discharge state or capacity at the same time as this independently monitors and controls the charge for each battery compartment. Note that spacers can be used to charge RCR123 cells, the terminals in the sides of the unit are not connected internally.

Specifications:

• Input: 100/240 VAC;
• Optional 12vdc car adapter (cigarette lighter adapter)
• Output: 4.2v with variable current up to 550mA per channel

NOTE: The power output of this charger is incorrect for the protected 3V 750 & 900mah RCR123A cells that we carry. We specifically do not recommend using this charger for those cells. Only use this charger with 3.6 & 3.7V cells.
