Is it 6 of one, half dozen of the other or is there one that’s truly better than the other. I’m (now) in the market for a new 4-Bay charger that will charge 20700’s as well as your typical 18650’s.


You’re not drinking water are you? You realize that’s an ingredient in antifreeze!

Had a luc4 that worked well for 20700s. 21700s were a really tight fit. So I went with the golisi s6. Amazon had them a while back for 29 bucks. The nitecores ive had have eventually died out in one of the bays. Never had any issues with the luc. Just wanted a new 6 bay

My 21700s fit into my 4 slot Nitecore. It is not listed as something that fits, but they do. I am just careful not to damage my wraps. I don't know bout 20700s, but I am assuming they are the same size? But I have a Golosi single slot just for my 21700s tho, since I only need one batt at a time.

I ended up having to pick one up quick and the closest shop just had the efest Luc 4, which I just finished charging my 21700’s for my Voopoo x217...it requires 2.

Ohhh, nice! I look at those two Chargers side-by-side and I don't see any difference in the length of the slots which seemed to be something everybody was stressing on the beginning I only see a difference in the width. Not a Bad Thing necessarily because I didn't pay much since I ordered that single slot from FastTech aka Slowwww Tech,

My first charger was an Efest Lush 4 bay. Still works fine, but only half an amp over 2 slots and just simple charging/full indicators. Nothing really wrong with that, but I wanted more.

I got an Opus a year ago and that thing is a toolbox for batteries. Jon said it's the most versatile and feature rich charger/analyzer LION sells and I'm sure he's right. At it's price point there's still nothing like it from looking around the web.

I got a Nitecore D4 in that bin full of stuff from the guy on Craigslist and that also works fine, except 3/4 of an amp at all times no matter how many bays are in use. And yes REALLY snug for 21700s. I had an I2 that I gave away as part of a birthday present.

Myvpro had a sale a little while back and I grabbed a Golisi S2 just because. (I think it was 14 bucks) Great charger. The only thing I wish is that it allowed you to pick it's charging amperage. It forces 2 amps unless you use both slots. (Man that Opus spoils you for versatility. 4 fully independent slots that you can set to 200, 500, 700, 1, 1.5 and 2 amps though only the outer 2 slots allow 1.5 and 2, But you can have all 4 slots doing different operations and or charging at different rates if you want to)

You know what's worth having? Those 4 dollar single bay Enook USB chargers that LION has. He had them on introductory sale for 2:99 and I got 2 with a battery order. They easily fit 21700s and charge at a full amp with all the protections. I use em for singles for mechs.

EDIT: Now that I think of it, I believe it's the Efest that's super tight for 21700s.
