I highly recommend using this charger! I'm sure it will fit your needs perfectly!

Short Review: This charger works great. It has 3 charging speeds. It charger 18650 batteries exactly as a charger should. You don't get a wall charger input, so you either have to use your computer's USB slot, or you can use a phone charger brick. It does come with the charging cord. This charger has not decreased the life of my batteries at all. I highly recommend using this charger! I'm sure it will fit your needs perfectly!

Amazing!! Get this!

Honestly, I'm surprised by how great this charger is. I absolutely love it. It works amazingly. It's easy to use. I love that it shows when the batteries are charged and that it fits more than one size/type of battery. Fantastic. I totally recommend it.

Wait... you mean I can charge 4?!?!

I love this charger, I previously used one with two slots and it was always a waiting game until I was able to charge my other set (I know, cliche review; “...love this product, because it does what I need it to do, which is awesome because that’s what I paid for...”). I use it to charge my vape batteries (I quit smoking cigarettes in October but, I was a pack a day so I found I was using my vape kind of a lot.... absolutely chugs 18650 batteries and all too often I drained a set before the others finished charging... I ended up buying multiple sets of batteries because the local “smoke shops” had sketchy looking chargers... That’s expensive so checked on amazon for affordable batteries, one I clicked featured this charger in the “people also bought “ section... as soon as I saw it I was like, “wait, ... 4 at once...? DUH WHAT WAS I THINKING?!? ... *buy it now*” TLDR great product for hobbyists and their quadcopters and for unironic, unpretentious and definitely not douchey hipster “vapers”. ZERO buyer’s remorse

It is worth!

I ordered this 4-slots battery charger and it arrived fast. It fits what saying on website and worked very well! The retracted spring for battery holder provides not only a good view of its display it also allows different size battery to work on the charger. The size is also small to carry to use when sitting in any location. It can charge 4 at the same time or either 1-3 individually, and charge speed is fast. Half hour charging allow to use several days. I love it!

AMAZING!!!!

This charger is amazing for battery’s I like how I can change the charging time and everything over all just buy this. I use it for my vape battery’s and I will be buying another one of thes once I get more battery’s.

Charges great

Charges super fast I use the 1.0A setting to charge my 18650 batterys. In my opinion it charges faster then my nitecore i2. It's nice you also can chose from 0.5A, 1.0A, and 2.0A also nice that it shows the battery charging. Would deffinetly buy again or recommend to a friend. Only down side is it does not come with a power brick just usb cable also I tried using my Samsung charger on it and it did not work might be a different pin count but just throwing that out there.

I was using another charger and found my self purchasing ...

I was using another charger and found my self purchasing batteries. Wondering why I then purchased this one and it brought batteries back to 100%even the ones the last one would not recharge. I charged the same two batteries I have in my pipe a week ago and just now on 92%. Whatever this product is doing it’s been done right. Everyone please purchase this product with out any doubt you won’t loose.

Awesome Portable Charger & Power Bank

I've held off posting a review on this item for a few months because I bought an off-brand charger prior and it started having problems with maintaining a connection with the usb cord. Glad to say this charger hasn't had that problem. It works perfectly for my needs (Charge 18650s for a Vape). I really appreciate it's reverse function (using it as a power bank). An absolute must-have for Vaping Campers or Camping Vapers who have spare batteries.

True 2 amp charge

Unlike some other titles to get you to buy their product, this is actually as stated. Charges in half the time as my other charger. You can trickle charge @ .5a or 2 amps while charging 2 batteries. Batteries don’t get hot either. Should of bought this first instead of paying for one that heats up and takes forever. Highly recommend

Great Charger *Use the Correct AC Adapter*

This charger works well, exactly as described. Optional charging output power is nice to have, although I haven't tested exactly how much faster charging at 2.0A is compared to .5A. This would also depend on the usb port you plug in to. The ports have held up well and connectors fit nice and snug. I'm charging 18650s and they fit very snug, don't have to worry about the batteries falling out at all. An AC outlet adapter would be nice, but most people have a usb wall adapter laying around like myself. Just make sure you're using an adapter or usb port that has high enough output. 2.0A minimum would be ideal if you want to charge at 2.0A.
