The Eleaf iStick range now pretty much covers all bases in terms of power and so far has done a great job of it. 
I suppose it’s a case of ‘If it aint broken..” and rightly so, I’m a big fan of their current box mod range. For those that want to see the other reviews carried out then they can be found at the following pages;
Now back to the iStick 30W, probably the most popular device in the iStick range.
In the box / Presentation
The Eleaf iStick 30W has the usual clean and tidy packaging with:
- 1 X 30W iStick (2200 mAh)
- 1 X EGO Adapter
- Manual
- USB Charging Cable
Battery/Body/Build
For those familiar with the 20W device then looks wise there are only slight changes. The good news is that the changes are an improvement. The most noticeable is the top plate plinth that has been added to accommodate tanks upto 23 mm without any overhang.
This is a subtle but great addition. The iStick now looks the business with the Subtank Mini and even lets the Atlantis 2 sit flush on top even though the latter still kind of dwarfs the device itself. 
The other additions are behind the scenes starting with an improved spring loaded pin and button lock functionality the same as the 50W. Of course the main internal change is of the course the improved power to 30W/ 8V and the compatibility with sub ohm tanks with resistances down to 0.4Ohms.
The size of the body is still tiny for the amount of power and the features it packs in and is also extremely light weight.
So far I am impressed yet again.
Functions
The power and function buttons are seated either end of the OLED screen. They are also super simple to use. If you are a new user you should have no issues getting to grips with this easily.
Here are the functions:
- 5 Click on/Off
- 3 Click to change from Volts to Watts or vice-versa
- Press and hold both arrow buttons to lock screen
- Use arrow button to go through Watts (5W-30W) and Volts (2V-8V)
The Screen Displays the following info
- Remaining Battery
- Current Resistance
- Current Volts and Watts
All the options for an easy to use box mod. It also has all the safety features you would expect from a device of this kind as well:
- 10 Second protection
- Short circuit protection
- Low Voltage protection
There isn’t a whole lot of things I can add from my other iStick reviews, this is everything that the 20W device was plus more. So far so good!
Overall
The plinth is a great deign feature and addition helping to keep the look clean when tanks upto 23mm are used. The additional features mentioned, while they may seem like little things, add even more to the product.
Performance
The 30W iStick can be used with 0.4 Ohms upto 5 Ohms, the latter of which I can’t see being used anytime soon. This simply means that we can now use sub ohm tanks with the box mod which opens up a new way of vaping for many.
As touched upon before the Subtank Mini and Atlantis 2 from Aspire sit flush on top of the 30W iStick and look just fine. A lot of my testing was however with the Eleaf Melo sub ohm tank. This (obviously) is from the same brand has most likely been designed with the iStick 30W in mind.
What a job they have done as well. It’s a great looking tank that looks fantastic on top. Not only that but it performs flawlessly. As did all of the other tanks that I tried. 
For those that are not interested in sub Ohm vaping then the Aspire Nautilus Mini comes highly recommended.
The battery is the same 2200 mAh capacity as the original and I was running this over two days before needing a re-charge.
Overall – The Eleaf iStick 30W performs flawlessly with both the sub ohm tanks and ‘standard’ clearomisers.
Overall – Final Review Verdict
I’m a big fan of all of the iStick range and the 30W is no different, for such a small device it packs a lot of power.
This would suit vapers stepping up from pen style e cigs as well as more advanced vapers looking for an ‘out and about’ e cig that is compatible with sub ohm tanks, albeit just down to 0.4 Ohms.
Here are the good and not so good that I found:
The Good:
- Small build sits perfectly in the palm of the hand making it easy to take out and about.
- Very respectable 2200 mAh battery life.
- Simple to use.
- Lock function.
- Can seat tanks up-to 23mm without overhang
- EGO adapter included.
The Not So Good:
- Nothing that comes to mind.

Final Eleaf iStick 30W Review Verdict:
Excellent: Highly Recommended
Not a bad looking battery, and easy to use. Teamed it up with an Aspire K2 tank.
Battery life has never been great, but worse still, build quality has proven to be abysmal. First one went back to the shop after 1 week, as the USB connector had pushed back into the housing.
The replacement started to fall apart after 2 weeks. The metal plates on the top and bottom becoming loose as the screws fell out. And once again, the USB connector retreating further inside the battery housing, making charging problematic.
Battled on with the battery for 3 months. It’s a shame really as it would have been good if not for poor quality build and internals. Score 2/5.
the product is easy to start with, though it uses small size tanks. i have many friends who have this product and its a very nice product in terms of use and design.
I like the iSticks, I’ve had three so far, 20, 30, and 100w, they are pretty durable and I haven’t had any major issues with my mods
es un producto muy bueno, lamentablemente se me ha dañado!! deje de fumar con él
Me and my girlfriend both bought this product along with Kanger Genitank mega tanks, both ileafs were broken within one month, exchanged for replacements and the same problems! Loose top plates, arrow buttons get stuck in, no atomiser messages, and for some reason after a while the power seems to drop, the voltage is still the same, even with new atomisers it just doesn’t produce a good throat hit without taking a huge 6 second drag. Hate being a whiner but I don’t think these things are very complex and I can’t see why 4 out of 4 would fail within 3 months other than cheap lazy manufacturing, not good when there is so much competition around.
I got my 30W iStick battery less than 6 months ago. Everything was going great until when I tried to hit it I wasn’t getting anything and then when I released the button it started going off and I had to take my tank off so it would stop. On top of that my top felt lose. I only put my ecig in my purse while I’m not using it which has nothing to harm it. So I took a tiny screw driver to tighten the top of my battery, one of the screws broke, which was my fault. Although it kept going off after I pressed the button and then recently it would start going off as if I was hitting it without me touching the button or even holding it in my hand. I don’t recommend getting this brand with all of the problems I’ve had with it.
This device fires anything and does it well I own 2 battery mods this istick 30w and the ijust 2.
It looks the tits with anything on It including my aspire k1 glassomiser.
Teamed up with the one of the subtanks this becomes a cloud machine and with a dripper to.
Brilliant device as a upgrade from a pen battery lasts ages well worth a try
In May I bought the’ iStick 30W’ to complement my MVP3 as I am vapouring more than I was smoking (but often with 0 mg nicotine).
It worked for about 2 months until recharging took at first 48 hours and then soon stopped charging altogether. My local shop replaced it – just like that! – with a new one. This new one worked for one week! It was more than half charged (indicating 3 notches out of 5) when I plugged it in and have been recharging now for two days without seeing any progress. I only hope my ‘iStick 50W’ won’t show the same temper. (Had it only for 7 days) Watch this space.
