Released only a few months ago, the iStick 50 Watt is a box mod personal vaporizer (PV) from eLeaf which boasts a 4400mAH battery as well as sub ohm capabilities. I’ve been excited to try the 50 watt iStick, as the 20 watt iStick (combined with an Aspire Nautilus) has been my daily vaping device for a while now. Although this version of the iStick supports sub ohm coil builds, keep in mind that it can only reach resistances as low as 0.5 ohms (resistances lower than this will cause the unit to not fire). Arriving in a box similar to my original 20 watt iStick, the 50 watt version came with:iStick 50 Watt Sub Ohm Box.JPG

Because size does matter when it comes to portability, once I took my unit out of the packaging the first thing I did was examine how large it is. In comparison with the 20 watt iStick, the 50 watt variant is nearly the width and only a little taller. I usually like using the smallest device possible which can still produce a solid experience, and the iStick 50w definitely didn’t feel that much bigger in my hand. In fact, as someone who has big hands I actually found it to be more ergonomic than the 20 watt model! Being slim and fairly short in height, it didn’t take up much pocket space either (especially when you factor in how much power is at your fingertips). Moreover, the buttons felt much firmer than my 20 watt model, and I suspect that Eleaf changed the kind of buttons they used for the 50 watt (and possibly the other models as well). Much like the 20 watt model, the 50 watt iStick uses an OLED screen which displays information including remaining battery life, atomizer resistance, and whether the unit is operating in variable voltage or wattage mode. There’s also a puff counter which measures how long you take each puff for, but I find this information to be fairly useless (plus the reading disappears quickly, making it hard to read it). The 50 watt iStick also includes a number of suggestions that customers had for improving the original 20 Watt model, and these include the addition of a spring loading 510 connector as well as centering the atomizer post so that certain style atomizers hang flush with all edges. iStick 50 Watt.JPG

The unit arrives pre-charged, so after my inspection I attached a new Aspire Atlantis which I had purchased just for the occasion. After filling the Atlantis with some high VG e-liquid, I attached it and took a few puffs at 20 watts. Compared to my previous non sub ohm setups, the vapor was warmer and thicker and the flavor richer. As I increased the wattage, the vapor became warmer and hotter, but I found the sweet spot for me to be about 22 watts while using the Atlantis. Aside from trying out a sub ohm atomizer, I also tried out the Silo Lite (uses Aspire BVCs) and Aspire Nautilus and both of them performed well on with the larger battery capacity. When using these types of atomizers I recommend sticking to lower wattages or you risk burning your juice easier than you would normally.

The iStick 50 watt comes with a 4400mAh non-replaceable lithium battery (nearly double the iTaste MVP 2.0’s 2600mAH!). The large battery translates into very good battery life, and as a heavy vaper I can usually go several days before needing to recharge (which takes a few hours when the battery is fully empty). Furthermore, Eleaf moved the USB charging port from the bottom of the unit (where it was for the 20 watt iStick) to the side, making it possible to charge the 50 watt model while its standing up (which is great for keeping your tanks upright).As a whole, I was very impressed with the 50 watt iStick and have been using it in conjunction with an Aspire Atlantis as my daily workhorse for the past week now, and I can definitely see myself using it for the next while. The long lasting battery, ergonomic form factor, and with sub ohm capability makes for a great hassle-free experience! I recommend the 50 watt iLeaf (with an Atlantis or Kanger Subtank) to anyone who is looking for an affordable set it and forget sub ohm solution. Although the iStick is great for entry level hobbyists, more experienced coil builders may find the 0.5 ohm resistance minimum to be a little high for their builds.


Eleaf iSmoka iStick 50W Sub OHM Box Mod

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.
