I’m a big fan of both the iStick 20W and the Mini iStick, both do a great job and I’ve found myself using both devices repeatedly over the last few months.

The main reason being is due to the small form factor (+ battery capacity + power) making iSticks easy and ideal for vaping when out and about.iStick 50 W in the handSo onto this review and I am taking a look at the Eleaf iStick 50W which (along with the 30W) is the latest addition to the current iStick e cig lineup.

This electronic cigarette was purchased, by myself, for the purposes of this review.

In the box / Presentation

The Eleaf iStick 50W comes in a tidy cardboard presentation box and includes the following.

  • 1 X 50W iStick (4400 mAh)
  • 1 X EGO Adapter
  • Manual
  • USB Charging Cable


If you have used or seen the 20W iStick then you will be familiar with the shape and look of the 50W version. The only difference is, obviously, that the 50W version is a chunkier, weightier device.

With a huge 4400 mAh battery this is to be expected. Having said that, the size is still compact and the added weight actually makes it feel like a much more robust bit of kit. Eleaf iStick 50W Review

The curves make the iStick fit the palm of the hand perfectly making it a comfortable device to hold.

The power button sits on the same place with the watt/volt selector buttons now sit on the front face of the body with the OLED screen just below. I went for the blue which I think looks great, it is also available in black, silver and pink.

I will say though I’ve just been using the MVP 3 for the last week and the display on that big fella is superb. With that in mind maybe I’m being too fussy but still, with a bigger device the screen could have been larger.iStick 50w nd MVP3 size comparison

iStick 50W OLED screen functions

The display is the same as the 20W with battery capacity indicator, atomiser resistance, volt/watt output and of course your voltage/wattage setting. The functions themselves are also similar apart from one main improvement.

Pressing the two arrow selector buttons together for a couple of seconds will lock the screen without shutting down the device. This just ensures you don’t accidentally change your settings as right handers will have the arrows sat palm inwards when vaping.The 5 button on/off is still there as well.

Changing from volts to watts, or vice versa, is done by simply pressing the power button three times. From here you can use the arrow buttons to select up or down to choose your preferred setting. Due to the variable voltage and wattage settings being larger – 2V-10V and 5W-50W output range – the iStick does allow you to run through the settings pretty quick by simply keeping one of the arrow buttons pressed.

The watts can move in 0.5W increments and the volts in 0.1 increments. The automatic scrolling through the numbers from the 20W has been done away with which wasn’t something I saw as being particularly useful.

So overall usability is super simple.

There are of course additional features.

iStick 50W Features

  • 510 Thread (comes supplied with EGO adapter)
  • 2V-10V
  • 5W – 50W
  • Fire down to 0.2 Ohm
  • Temperature Alarm – If device goes over 70’C output will shut off and display will show ‘Temp Protection’
  • Vape whilst charging. Micro USB position is good for this on the underside of the device, not the bottom.
  • Ability to flip display screen Performance


A great design that is comfortable in the hand is something I have come to expect from the iStick range and the 50W although a touch larger and heavier fits the mould. The functions are easy to use and the button rattle from previous models is no longer present, the only thing I would have liked to see is maybe a larger OLED screen.

How Does The Eleaf iStick 50W Perform?

The 50W iStick can fire from 0.2 Ohms, I tried a number of tanks/clearomisers on the 50W iStick. First off I tried all the Kanger Subtanks to see what looked the best. I decided to stick with the Subtank Mini which at 22mm fits perfectly. With a 0.5 Ohm coil it also performed a treat with the e-liquid I was using.

For my personal tastes the sweet spot was actually around 22W and after 25W the juice I used became too harsh. Of course depending on the e-liquid flavour/type you use and the type of vape you like these settings will be different.

The Aspire Atlantis 2 tank also looks great on the 50W and with the 0.5 Ohm coil also performs well. The box mod handle them all easily. iStick 50W with Nautilus tank close up

For the way I vape 50W is overkill. At the moment 20W is fine for my needs although it has to be said the battery size does come in handy.

That brings us to the length of time the battery lasts…. Well, at a huge 4400mAh I was getting 4 days easily as a moderate vaper switching between 10W to 22W. Even chain vapers should get a respectable run from this battery.


The Eleaf iStick 50W handled the Kanger and Aspire Sub Ohm tanks I tried no problem, the 22mm tanks fit perfectly. Add to this the huge 4400 mAh battery life that saw me into 4 days then I have no complaints at all.

Final Review Verdict

Another great addition to the iStick range for certain vapers. The 50W maximum setting it has to be said is wasted on my current personal vaping habits and will likely be unnecessary for a large percentage of vapers out there. Around the 20-30W mark is plenty for me but this does give me room to grow if need.

Having said that, the huge battery life makes this worth considering even if you don’t vape at the higher wattage and use sub ohm coil heads. The likes of the Aspire Nautilus work just fine with this and if you don’t mind the slight step up in size from the 20/30W iStick then you could get an extra day or two vaping time.

Here are the good and not so good that I found:


  • Battery life is superb at 4400 mAh.
  • Still a fairly compact device despite the capacity.
  • Build quality is decent.
  • Very comfortable in the palm
  • Functions are simple to use.
  • Lock function without the need to turn device off.
  • Handles Kanger Subtank and Aspire Atlantis with ease
  • 510 & EGO compatible, the latter by way of adapter.
  • OLED display is clear.


  • Not suitable for vapers that want to drop south of 0.4 oHms.
  • Would be nice to see a bigger and brighter OLED display.
  • Silver top plate is a fingerprint magnet.

  1. Pretty happy with mine, good pocket size, easy to use, the battery lasts forever.
    Wish I had a second one but it’s discontinued these days.
    Occassionally it’ll turn itself off and won’t turn on even with battery life, but if I plug the charger in then it starts working again.

  2. Excellent device was in its time. Easy to use.
    The sun is difficult to see what is written on the display. His money’s worth, would recommend their friends to beginners.

  3. I tried to quit smoking on & off for around 10 years using various methods. I started vaping around 3 years ago using a small ego pen type thing & other various small vapes.I found this device last year , bought an Atlantis Aspire tank to go with it and haven’t looked back.I love the throat hit you get with a good quality juice,ease of use and design & now I don’t smoke at all.I’d give it a 4 1/2 out of 5.

  4. I still use this mod frequently, even though over the past year I’ve purchased many other mods. This mod consistently provides amazing power! The battery lasts all day with heavy vaping. It’s a great mod, out of all the mods I own this is still in the top 3 favorites! It’s worth it!

  5. This mod is safe, reliable and always performs. I use it alot and can recharge it in the care with the usb charger. The port is becoming a bit loose from use but, I have cut down cigarettes almost to none.

  6. This product is a great introductory unit for new vapers. It never was the greatest thing on the market but it held it’s own quite well. In 2016, it has been surpassed by newer tech; however, the ease of use and for the $ you can score them for you really can’t go wrong. The main downside is it’s power limitations. Because of the 50W cap you’ll find that some of your big name tanks (Crown, TFV4, Herakles Plus) are pretty much unusable on this mod. That said, there are PLENTY of alternatives to get you up and running with a satisfying experience until the time comes where you may opt for “bigger and better.” You’ll get your moneys worth out of this piece.

  7. It’s a great product but there are clones out there. The clones do not match the original Eleaf 50W iStick quality so just because it looks the same an is cheaper . . . can cost you in the long run. The originals have a hidden menu – If you click 10 times to turn on, from off, rather than the normal 5 the display will show the temperature of the battery in deg C. A great check to see how or if it is being over worked. Mine currently says “28” but I think the the iStick will stop working, automatically, at 70 deg.

  8. I bought the I stick 50w two months ago. Within a few weeks the display screen started to fade. This resulted in it a total black out and the battery turning itself on and off. I took the battery back to the shop who refused to refund or replace as the warranty only had 3 days.
    They advised to email Eleaf, which I have done with no response.
    This morning 06/11/2015 the battery exploded in my hand when I was trying to turn it on. Sparks came from the charger point and the battery was smoking. It became so hot it could not be handled and the display screen has melted.
    This is now a clear safety issue for customers. They claim this product has a heat cut out – I can definitely confirm that is not the case. Still no response from eleaf !!!

  9. I really enjoy the mods look, feel and functionality of the unit. With that being said I don’t like the hazard created by poorly designing the rechargeable micro USB port, however I do like that it is a micro USB and is compatible with almost if not all cell phone chargers sold in Canada today.

    The one thing that truly disappoints be has to be the price in which these units retail at. The mods are made in China and that should be reflected within the purchase price of the unit.

  10. The 30W iStick is not better – same problem with recharging failure. I am on my fourth device now in 4 months. Go for the Innokin products.

  11. iStick 50W is a super upgraded version based on iStick series batteries. Powerful vapor can be generated due to the expanded range of output voltage(2V-10V)/ wattage(5W-50W) with 4400 mAh battery capacity. It retains strong spring connector and wear-resistant stainless steel thread. Moreover, the additional temperature alarm function makes it high-safety even in strong vaping. Great feeling when you hold it because of its size and the rounded edges, while side charging port is also a plus.

  12. iSmoka has no US presence; phone number is international exchange. The retailer I purchased from only supports for 30 days after purchase. Display is too dim to read unless in a dark room. Retailer should exchange as long as within iSmoka warranty period, and get credit from them. Purchased from Smokecignals in Baton Rouge, LA.

  13. its a smashing piece of kit to help you disguard the fags, i have in the passed had other vape devices which didnt do a lot and i still had fags when i went to gigs but with this i done need to buy fags. im using a lemo 2 tank with this and its fantastic, easy to use and understand features, which give you a proper lung hit every time. i run mine at 25w which gives me 0.6 ish ohms so good for the sub ohm chasers. have had a problem with the power as once i hit the power button it cut out but soon solved with a short hit with the charger it springs back to life right away. all in all very worth the money and will highly recommend it to friends.

  14. You really get a ”hit” using this with ”witchcraft”, Im using ”frost Candy” I actually know I will never smoke another cig’.
