Outstanding battery life, convenient size, and in full color.

Experience the Eleaf iStick, and you'll see why so many vapers are raving about this battery! This is a new product, built off the success Eleaf has had with their more traditional stick style batteries. With an annodized aluminum coating, it comes in a varity of metallic colors, fits with room to spare in any pocket or purse, and will give you a great set of options to vape the way you want to, all day long (this 2200 mAh battery is a beast!)

The iStick features an OLED screen which displays information like current voltage and wattage settings, puff timer for each puff, battery life and ohm metering. If all that wasn't enough, the iStick features passthrough charging so you can keep vaping while you're charging up.

    Does the job

    Posted by Jay on 21st Apr 2020

    It does what I bought it to do but, I have a feeling it'll break the first time I stand up with it on my lap.

    Bad buy!

    Posted by Steven B on 26th May 2019

    I've ordered 3 of these and the batteries in them never hold a charge like they should. The very 1st ones were great but the last ones bad, bad, bad.

    Eleaf 20 Watt battery

    Posted by Larry White on 23rd Apr 2019

    I have been vaping for about 7 years. I have used the Leaf Eleaf 20 watt variable voltage for the last 5 years. This is the best battery for me, I like the size and the life span these batteries.

    The battery charge lasts great. My GeniTank fits perfectly. The battery itself has a good weight to it and is comfortable to hold.

    Eleaf 20 watt battery

    Posted by Larry White on 24th Mar 2018

    The Eleaf 20 watt variable voltage battery is the only battery I use. It is the perfect size and allows you to adjust the voltage to suit the user. It has a very easy to use and recharge quickly, I enjoy the by-pass feature of the battery. I have tried other batteries the size are awkward and uncomfortable to use. I would highly recommend this battery for anyone. Also I want to say American Eliquid Store is my ONLY on line store, good prices, great products, and amazing customer service.

    Eleaf I stick

    Posted by Elaine on 5th Apr 2017

    Love this thing! I use it constantly and after a full 24 hours it's still going strong. I put it on the charger for awhile every evening and it charges really fast. My husband liked it so much that I immediately ordered 2 more. One feature I thought was pretty neat: I refilled the tank and obviously didn't have the coil exactly right. The message showed on the side "atomizer short". I took it apart, cleaned and replaced the same coil and it worked just fine.

    Get used to the size, weight

    Posted by bob on 21st Oct 2016

    If you're accustomed to the long, narrow "cigarette style" batteries, this one will feel heavy and clunky. It takes a while to find the right way to hold it since it 's unbalanced and heavy at the battery end. However, once you have found that sweet spot, this is a great battery with power and long life. I've never had a battery before that lasts the entire evening. A keeper for sure.

    Eleaf iStick 20W

    Posted by Unknown on 15th Jun 2016

    Not a bad little battery, but I would recommend spending a little more money for a more powerful battery. Also, it would have been nice if it was stated that no charger comes with this battery, not too pleased about that!

    iStick 20 watt variable voltage and wattage

    Posted by Unknown on 3rd Jun 2015

    This is the 2nd battery I have bought the 1st lasted only 2 months and I was disappointed I was having problems with the battery. Having said that I was very pleased with the battery it was very good and it worked great, till it failed. The battery really worked well for me so I had to give it another try so far it is working great. Hopefully this battery will have a longer life span, I feel it is a good product and I happened to get a bad one.
