The Efest LUC V2 is one of our favorite Li-ion chargers on the market.  This is the version that includes a car adapter for charging from a cigarette lighter.  If you're looking for the Efest LUC charger without the car adapter, click here.

It's a very high quality charger that can charge up to 2 batteries at a time, at 500-1000mA charging rates.  It tells you the charge levels via LCD screen.  It's compatible with most 3.7V Lithium Ion or Li-Mn batteries such as 10440, 14500, 14650, 18500, 17670, 18650, 18700, 26500 etc. 

We generally do NOT recommend this charger for 26650/20700/21700.

It also has kind of a cool feature where if you have a charged battery loaded you can use it as a portable power pack and charge USB devices like mobile phones, tablets, and the like using a USB cord.

Comes in a high quality storage box too to complete the high end feel.

Note that no batteries are included with the charger, they're shown in some pictures for display purposes.

Doesn’t work

Ordered this product in hopes of having a car charger for my batteries. Received the charger and the charger didn’t work with either the car charger or the wall charger. Not impressed already threw it in the trash.
