This is one of our favorite Li-ion chargers on the market, and definitely is the best deal around.  This is the version without a cigarette lighter car charger adapter (the LUC4 charger with a car adapter is here)

It's a very high quality charger that can charge up to 4 batteries at a time, at 0.5-2A 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, 26650 etc.  It can also charge 15270 or 14250 batteries if you use spacers.

*Note that this charger should NOT be used with the IJOY 20700. It is not long enough for that battery, which is longer than standard 20700s.*

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.

Very impressed

I ordered this battery charger because i had one before & knew it was already a good one but i was very impressed with this site after i ordered my charger on a friday night it got here monday morning. Shipping was very fast an that's what i like, getting a good deal, good product & not having to wait or be spun around. Highly recommend any order from here if anybody is inbetween & can't decide...go for it you won't regret nothing

Impressive reliable, quality charger

Perfect charger not only for the LG 18650 batteries I ordered from here, but for any size smaller, too. It has 3 amperage settings but of course if you have the time, the slowest (.5A) is always better for your batteries' longevity. The LCD display is great, and it's easy to see where they are at in their charging cycle and how much they have left. Removable AC adapter isn't too short, and the entire product just feels really solid. I don't anticipate having any issues with this charger for a long time based on it's incredibly reliable performance over the past year and a half. I would recommend this to everyone because the price is extremely low for this king of build quality.
