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.

  • What device/application do you use this with? Wismec Rx300 V/W LG HB4 18650

Best quad 18650 charger I've used

Efest generally is known for their very poor product quality and customer support. This charger has been the king of the 4x18650 chargers. The new version is perfected. The only thing better would be in-device (or on-board) charging featured in every device powered by 18650s and the numerous other batteries this thing charges. That's my opinion. Don't buy a different charger if you subohm vaporize e-liquids with battery box mods. I'm not a fan of Efest but this is the best charger.

Hi Nino - thanks for your feedback. We don't carry any products (Efest or otherwise) that we don't feel are of sufficient quality. Hope that helps set your mind at ease when ordering in the future.

Solid

This is my first multi-bay charger. It defaults at 2.0A charging rate. I charge my batteries at 0.5A. Takes a while yet the battery's charge lasts longer. Twice it changed to 2.0A for some wierd reason, not sure how. I'd give it a 5-star rating but I'm not experienced with other chargers.

  • What device/application do you use this with? I use it for my Sigelei Kaos and my Smok Nano batteries

No regrets

Absolutely love how quick it charges my batteries regarless if it's just 2 or 4 18650 batteries. Was going to with the Nitecore, but it lacked all the safety features of the EFest. Delivery was a day early definitely would recommend and buy again!

  • What device/application do you use this with? Charging batteries, 18650, 26650 and 20700

Good Charger

Great spare charger to have on hand, nice screens monitoring batteries, simple and clean, convenient USB port for charging other devices on the go, 20700 batteries fit but tightly installing and removing them from charger.
