Sigelei 75W TC
Sigelei seem to have abandoned their cardboard style boxes in favor of an acrylic unit with a paper wrapper around it. It works, likely costs them a bit less to manufacturer and they have apparently passed the savings on to vapers.
There's no room to spare in the box. The even stored the micro USB charging cable inside the empty battery cavity to save on space.
One of the surprising specifications is the coil resistance support: the Sigelei 75W TC supports resistance as low as 0.05 ohms, and as high as 2.5 ohms – that's for Kanthal, Nichrome, AND Nickel 200 wire.
I've been using the Sigelei 75W for over 5 weeks now. I like the size, I like the flexibility, and the range of this device. It's not like the other Sigelei devices though. I expected it to work like the Sigelei 150W TC, but it doesn't. The user interface is different and more akin to other TC lower cost devices. I have always regarded Sigelei as one of the most accurate devices on the market. The Sigelei 150W (both the original and the TC versions) are the most accurate in the market – you could rely on the Sigelei 150W. This Sigelei 75W is nothing like its siblings. The temperature control is nowhere near accurate. I can take the same tank off the Sigelei 150W where I was vaping at 420 degrees F and put it on the Sigelei 75W at 420 degrees F – the vape experience is entirely different. To get the same vape experience as the Sigelei 150W, you have to crank up the Sigelei 75W up to 500 degrees F.
To make sure this wasn't isolated to one tank, I tried a variety of tanks. All had identical results, you have to crank the Sigelei 75W nearly 20% higher in temperature to get the same vape experience as the Sigelei 150W TC. I tried Ni200, as well as Kanthal A1. Same issue.
The Sigelei 75W is terribly inefficient with power. I can barely get through 4.0 ml of juice before needing a battery change. Changing the battery to higher/lower mAh or higher/lower capacity have no effect. This is the most power hungry device I have ever tried.
Once you get the temperature working with the tank combination you have, the vape experience is good. Power transfer from the battery through to the coil is near instantaneous and sustains well.
The Sigelei Mini 75W TC is available in a variety of colors. The unit I received is the black frame with Pearl Chrome battery covers. At the right are the other battery cover colors available: Brushed Nickel, Pearl Chrome, and Antique Copper.
Note that there are two battery covers, and both are magnetic. Remove both and you can insert/remove the battery from either side. It is a unique configuration and convenient.
You can see at the left what I mean about the different user interface compared to the Sigelei 150W (original or TC). This interface looks more like competitive low end devices than the familiar Sigelei look.
The information displayed is useful. The fire button, as you can see, is quite large. The adjustment buttons have a similar style to the other Sigelei products. But, all three buttons have a rattle that is disconcerning. Definitely not suggesting quality build.
So, what’s the verdict? Is it worth it?
I hate to say this, but the Sigelei 75W is at the low end of the mini size temperature control devices. It is not made with the same quality, accuracy, and efficiency that Sigelei is known for. I was also suprised to hear the button rattle from this device – and it just reinforces that the quality just isn't there. it does have the ability to charge through the micro USB port and I keep using it while travelling by car for that reason. It is a competent device.
