The Heatvape Defender 2 50w is the latest version of the Heatvape Defender, originally released in December 2014 as a small budget range 25w box mod with a built in 2600mah Lipo battery and an interesting dual ego/510 adaptor.
With the demand for more power from the vaping community, and higher powered budget small form factor mods such as the iStick series doing so well, Heatvape have updated the Defender with a few design tweaks as well as increasing the maximum power output to 50w.
Has the Heatvape Defender 50w got what it takes to compete with the latest range of budget box mods? Lets find out…
In The Box
The Heatvape Defender 50w comes packaged in a plastic casing, containing-
- 1x Heatvape Defender 50w box mod
- 1x USB charging cable
- 1x Instruction manual
Defender 2 50W Batter,Build And Looks
One thing I would say is that the Heatvape Defender 50w feels quite cheaply made, the buttons are pretty clicky in use and it has a bit of a budget feel, but that’s just my opinion! The 510 connector is centralised like it was on the original Heatvape Defender, which is pretty cool and looks really good with your tanks. 
The ego/510 connector has been done away with in favour of a spring loaded 510 connector, the ego/510 adaptors are a little outdated these days, and with the spring loaded 510 you get a flush fit with your atomisers, I tested many different ones on the Heatvape Defender 50w and all fit fine.
Form factor wise, the Heatvape Defender 50w feels great. It’s a really small mod that fits perfectly in the palm of your hand. Buttons are easy to reach and operate, and the OLED screen is very clear and visible, even in strong daylight. 
Information such as battery life, atomiser resistance, selected power and voltage is easily readable. There is a micro USB port present on the Heatvape Defender 50w so you can charge on the move, and a battery cap underneath the unit itself for you to insert an 18650 battery. 
The threading on the cap is really smooth and makes changing batteries easy.

How Does The Heatvape Defender 2 Perform?
The Heatvape Defender 50w is able to fire resistances down to 0.2ohm, so pretty much all of the latest and most popular sub ohm tanks will have no problem performing on the Heatvape Defender 50w. 
All of the tanks I used on the Heatvape Defender 50w worked with no issues, the only thing I would say is that tanks such as the Atlantis 2 with the 0.3ohm coil and the Sense Herakles with the 0.2ohm coil struggle a bit at 50w, as these coils are known to need 60W and above for optimum performance.
Not to worry too much, as you won’t have trouble running the Kangertech Subtank and similar tanks such as that, as 50w is more than enough for the coils used with those tanks.
You can switch between Variable Voltage (VV) mode and the more popular Variable Wattage (VW) mode.
A complaint about the original Heatvape Defender was that the power settings cycled through pretty slowly when holding down the plus or minus button, this time around holding down either of those buttons will increase the power in 1w increments very quickly, instead of the 0.1w increments when simply pressing the button. 
5 clicks of the power button is still used to turn on the Heatvape Defender 50w.
This time around there is no built in Lipo battery, the Heatvape Defender 50w is powered by a removable 18650 battery accessed through the battery cap at the bottom of the mod. You will need to supply your own, and make sure you purchase a minimum of a 20a rated battery, a Samsung 25r or Sony VTC4 is ideal for this unit.
Also ensure you purchase your batteries through a reputable seller, battery safety is not to be taken lightly.

With a single 18650 battery I find that I get around a full days use with the Heatvape Defender 50w at 20-30w, using it at 40w and above will decrease battery life pretty quickly and reduce battery life to a few hours.
It’s ideal to use in conjunction with the Kanger Subtank Mini for example for out and about vaping. You can charge on the move with the built in micro USB charging port, and Heatvape say this can also be used as a pass through so you can vape whilst charging.
Final Review Verdict
The Heatvape Defender 50w is a perfect little box mod for those on a budget, packing a 50W punch and sporting a great form factor which means it fits in your hand perfectly.
Retaining the centralised 510 connector means that the Heatvape Defender 50w sports a really unique look, and having your atomiser in the centre of the mod actually looks pretty cool!
It’s not really going to appeal to seasoned vapers, due to the lack of features, but for beginners the Heatvape Defender 50w is ideal, and the price is appealing too. It would make a handy back up mod for those looking for one!
The Good
- Very cheap for a 50w mod
- Very easy to use
- Ideal for beginners
- Great form factor
- Replaceable 18650 battery
- Fires down to 0.2ohm so most sub ohm tanks can be used
- Spring loaded 510 connector means a flush fit for your tanks
The Not So Good
- No longer has a built in battery so you need to supply your own (Maybe a negative for some)
- Build quality feels a little cheap
- Temperature control could have been included like on the Heatvape Invader Mini (Again only really a negative for more advanced vapers)
- Lacking in features so may not appeal to advanced users
