Sigelei 75W Plus Temperature Control

The Sigelei 75W Plus is actually a 90 Watt Variable Wattage device... Featuring Temperature Control with full support for both Ni200 and Titanium wire types. Unlike most other devices the 75W Plus is rather unique in that it takes a single 26650 battery yet despite this still retains a reasonably small form factor.

Sigelei 75W Plus (90W) Temperature Control

The Sigelei 75W Plus is actually a 90 Watt Variable Wattage device... Featuring Temperature Control with full support for both Ni200 and Titanium wire types. Unlike most other devices the 75W Plus is rather unique in that it takes a single 26650 battery yet despite this still retains a reasonably small form factor.

What’s in the box?

  • 1x Sigelei 75W Plus
  • 1x 26650 Battery
  • Silicone Protective Sleeve
  • Micro-USB Cable
  • Sigelei 75W Plus User Manual
  • 1x Ares Sub Ohm Tank
  • 1x 0.5ohm Coil (Pre-Fitted)
  • 1x Spare 0.2ohm Ni200 Coil
  • Ares Tank User Manual
  • Assorted Warranty Cards

The overall packaging and manual still maintain that this is a 75W device but Sigelei have added a card wrapper to the box stating “75W Plus upgraded to 90W Plus. Different Wattage, same operation”. Admittedly this does kind of make things a little confusing but quite a few vendors are listing this device as the 90W Plus which does help matters.

Sigelei 75W Plus Temperature Control styling and build quality

The 75W Plus is very well put together just like you would expect a Sigelei device to be. It is of course slightly larger than typical single 18650 mods but not as bulky as a lot of dual 18650 devices. The form factor is as good as it can be for something that takes a 26650 battery. All of the edges are nicely rounded off and it feels very good in the hand!

Surprisingly enough the device is much lighter than I expected. While it is noticeably heftier than a standard 18650 device I found it far more comfortable to hold for extended periods of time than a RX200 or a dual 18650 device.  

In terms of styling it shares some similarities with the Sigelei 150W TC but unlike that device the 75W Plus does not have a rubberised finish. The buttons are nice and feel suitably “clicky”. The 510 pin is spring-loaded and unlike the Sigelei 150W TC all of the atomizers I tried sat completely flush with no visible gap. The pin itself is made from copper to ensure excellent conductivity.

The battery compartment cover is reasonably easy to remove but I did find I sometimes needed to dig my nails in to get a good grip on it. The magnets are very strong and the cover does not wobble at all. Fitting the battery is straightforward but it is a slightly tight fit. The correct battery orientation is clearly marked and there is a ribbon to assist with battery removal. The battery contacts are also made from copper. The cover has three large slots as well as six holes to provide excellent ventilation. The only downside is you can see the battery though them which may bother people who are extremely OCD about the looks of their device. Another thing to keep in mind is that you will be covering these vents when you hold it in your hand. However additional ventilation is provided for by fifteen holes in the base of the device. The Micro-USB Port is also located on the base. Sadly the device does not allow you to upgrade the firmware which you might see as a potential con. The port allows for USB charging so you will not require an external charger.

The screen is nicely done and will be instantly familiar to anyone who has used a Sigelei device before. It is both bright and clear and displays all of the typical information you might expect: Coil Resistance, Wattage and Voltage. In addition battery life is shown as is Temperature (when using that mode).

Ease of use

Anyone who has used a Sigelei device before or any other device that has a YIHI chip like the iPV’s will have absolutely no problems with the menu system. For anyone else the manual is clearly written and the operation of the device is accomplished in a very straightforward way so you shouldn’t run into problems.

  • Click the fire button five times to power the device on.
  • With the device switched on click the fire button five times to enter the menu.
  • Cycle through the various menu options by pressing the fire button.
  • To adjust menu options use the plus and minus buttons.
  • To switch the device off go into the menu and select “System Off” and confirm with either the plus or minus button.
  • To set the resistance when using Temperature Control hold down the plus and minus buttons simultaneously.


Coming from someone who really likes Sigelei devices and owns quite a few of them I anticipated no problems with the 75W Plus. I am pleased to report the device works well and I encountered no issues at all. To be honest it really felt like I was using a smaller version of my 150W TC and I certainly enjoyed using it.

I tested Variable Wattage Mode by using my GP Heron V2 and my Raptor RDA that both currently have Kanthal builds. The vape quality was exactly the same as it is on my other devices.

To test the Temperature Control functionality I fitted my Freemax Scylla to the device. The Scylla is currently fitted with a Ni200 coil so I set the 75W Plus to 240°C/ 40 Joules. I got exactly the same vape as my Sigelei 150W TC which is consistently decent. The 75W Plus has full support for Titanium coils as well as Ni200 and it has a maximum output of 75 Joules in Temperature Control Mode.

Battery life as you might expect is significantly longer than a typical single battery device. I was vaping between 30-40W for a good twelve hours of vaping and the battery charge is still at 20%. Unlike other devices you might purchase the 75W Plus does come with an included 26650 battery.

Sigelei Ares Tank

Included in the box is the Sigelei Ares and it’s a rather nice tank which makes the overall package very attractive. Two coils are included, a Kanthal one pre-fitted and a spare Ni200 coil.

The overall machining is very good and for the most part everything fits together well. The only exception was the top which was a little stiff to unscrew the first time I wanted to fill the tank but I would expect it to get better the more you use it. The top does have some knurling which certainly helps when you need to unscrew it. Filling is easy and there is plenty of room for your juice bottle nozzles.

The drip tip is of the wide bore variety and is made from Stainless Steel but it does feature an inner Delrin piece to minimise the amount of heat that reaches your lips. The Ares has plenty of airflow options and can be fully opened up for direct lung inhales or heavily closed down to suit mouth to lung users.

I tried this tank using the pre-fitted 0.5ohm Kanthal coil and filled it up with some of Halcyon Haze’s Earth Brother. 35-40W was the sweet spot for me and I thought that the flavour was very good. The Ares puts out plenty of vapour even when the airflow is heavily closed down. I was rather impressed with it and the only negative I could find is that it does tend to drain your juice quite quickly. Sometimes when you get a tank included as part of the overall package they are not always that great but that is not the case here because the Ares is seriously good!


In my opinion the 75W Plus is another superb device from Sigelei.  It has good battery life and an excellent form factor. Another bonus is that you only ever have to charge one battery at a time and not rely on a matched pair. The only slight cons are the lack of upgradeable firmware and the absence of 316 Stainless Steel coil support. Regardless I really liked this device a lot and if my house wasn’t full of dual 18650 devices then the 75W Plus might seriously tempt me.

I think that if you are a recent convert to vaping then the 26650 mod route might be a very worthwhile choice since this is an excellent package that would make a great starter set!

We were sent this mod to try out from the team at Sparks Ecigs. As well as their online shop they also have stores in High Wycombe, Aylesbury and Hemel Hempstead so if you are in the area check them out!
