Sigelei J80

New from Sigelei are the latest “J” series devices and they come in two varieties, an 80W model which we received for review and a 150W version. The 80W device is even more discrete than Eleaf’s iStick Pico, which is no mean feat!

Sigelei J80 styling and build quality

The J80 is in my opinion a very stylish device since the red and black finish looks highly appealing and very modern. In terms of shape the device bears a great deal of similarity to the Sigelei 213 box mod but it is considerably smaller. What is remarkable is that this 80W device is even more discrete than Eleaf’s iStick Pico, which is no mean feat!

Constructed from Zinc Alloy the J80 is of a comfortable weight and, unlike some other Sigelei devices I have reviewed recently, it feels quite robust and durable. The 510 threading is made from Stainless Steel so it should last a considerable amount of time. The pin itself is spring-loaded so your atomizer should sit completely flush with the device.

The display is of a decent size considering the overall compact nature of this device and it is both bright and clear with an easily readable font. A great deal of additional information is shown, much like the Sigelei 213, including all of the typical things such as Voltage, Wattage and Resistance. The Voltage of both batteries are show as is the remaining battery life. Temperature and wire type are also shown when using that mode.

What is rather nice is that the J80 features a sliding on/off switch to the edge of one of its side panels. It takes less than a couple of seconds for the device to power up so it makes for a good safety feature.

The J80 has more than sufficient venting and features fifteen decent sized holes located in its base. The Micro USB port is also located in the base but it is only for the purpose of charging the device and does not allow for firmware upgrades. The internal 2000mAh Li-Po is fitted internally and is not intended to be removed. In my opinion 2000mAh is more than sufficient for most modest vapers and will give you a decent amount of vape time providing you only spend small periods using higher Wattage or Temperature Control.

The overall form factor of this device is excellent since it is reasonably light and very comfortable to hold with the added advantage that it is highly discrete and compact!

Ease of use

  • The device can be locked/unlocked by five clicks of the fire button.
  • To enter the menu press the fire button three times. You can switch between supported wire types by using the plus and minus adjustment buttons and confirm your selection with the fire button.
  • To get the device to read the Resistance of your coil you have to hold down the fire button and the minus button simultaneously. I initially made the mistake of not doing this when I fitted my Freemax Pro to the device and it wouldn’t fire but once I realised it worked fine.
  • When using Temperature Control I advise you to set your desired Wattage first before switching modes and setting your Temperature.

The Sigelei 213 and J150 both let you adjust the Preheat settings but after scouring the manual for the J80 and checking the Internet I don’t believe this device has that particular function unless there is another way of doing it which at present eludes me.

In my opinion this is a straightforward device to use and after a small amount of time you will be completely familiar with it.

Sigelei J80 performance

In Wattage Mode the J80 works extremely well and not once did I run into any issues. I used both my Rose3 and my Achilles II RDA and the J80 performed consistently.

One thing I did notice is that the device initially felt rather underpowered in Temperature Control when set to my typical 240°C, it was an okay vape but not ideal. I then went into the menu and switched the device back to Wattage Mode and set it to 40W before switching back into Ni200 Mode. From that point it was a great vape with plenty of heat and vapour production and it compared really well to my other devices. I assume this is the workaround for the device not featuring the Preheat adjustment like its big brother, the J150. At the end of the day once you get used to it the J80 pefroms extremely well and I can't see any reason why anyone would be disappointed with it.

The 80W limit while a nice option is in my opinion a bit ridiculous since you won't get a massive amount of vape time at that Wattage with a 2000mAh battery. For modest vapers the battery should last all day and for anyone who wants to vape in the 40-60W region they should get a fair few hours out of it before having to recharge it. The battery charges quite fast and takes roughly two hours. 


In terms of build quality, styling and performance the Sigelei J80 is a very well put together product.  When you also factor in that it has a highly desirable form factor (even smaller than the iStick Pico) and does not require external batteries or a charger it makes this a very attractive piece of kit.

The only real downside to this device the fact that you can’t use it for long at its 80W limit since you will probably get about 20 minutes of use and it does seem a little odd for the manufacturer to give you that option. I’m not going to make a big deal about this because most typical users will be vaping this device at a far more realistic Wattage and you do still get a fairly decent amount of vape time when using it at 45-60W.

In some respects I feel the J80 is something of a return to form for Sigelei since the build quality is much better and it feels far more durable. While the J80 bears some similarities in function to the Sigelei 213 device it doesn't seemt to suffer from the 213's issues and I think that if you want a discrete device that looks good then this is definitely well worth considering!
