Sigelei 100W Plus

Vaporizers have come a long way over the last five years. In fact, they’ve seen a vast improvement over the last few months alone. A year ago, most power-regulated devices topped out at 11 watts or so, and they wouldn’t fire atomizers with a resistance of less than 1Ω.

The alternative were so-called mechanical mods, which used no circuitry and drew power directly from the battery. I could build lower-resistance coils to cheat more output, but the quality (and quantity) of vapor tapered off as the battery wore down over the day.

Better chips have since been developed over the last few months. Several manufacturers began using the Evolv DNA30 and DNA40 chips early last year, and now companies like Sigelei are using the newer Yihi sx330 chip to generate higher output.

Yes, this thing can go up to 100 watts. No, I haven’t run it that high. In fact, anything over 40 watts gets pretty overwhelming. But that’s not the point.

I usually build coils around 1.1Ω. On a mechanical mod, that gives me a maximum output of 14.5 watts on a fresh battery. That’s not bad when the batteries are fresh, but it tapers down to a wizened 8 watts or so after a few hours.

On the Sigelei, I can run at a higher wattage, and the chip ensures that quality remains the same. I ran it at 25 watts over a 13-hour workday and well into the evening, and the batteries were still at 75%.

Yes, I said “batteries,” plural. This thing uses two 18650 batteries. It’s not small, and it’s not light. That said, it’s not as bad as some folks say. Here it is with an MVP for comparison:

It’s a bit taller and wider, but it only weighs a couple of ounces more. As ergonomics go, it’s a big block of aluminum. The corners are nicely rounded, the edges are beveled, and the silver swooshes on the front are a nice touch. Still, it’s not winning any beauty contests.

It only has three buttons: one to fire and two for adjusting wattage. The display is likewise spartan:

I’ve really got all I need there. It reads wattage, voltage, battery state, and resistance. There are no superfluous puff counters or blinky distractions.

This device was obviously designed to do certain things right, and that’s it. The display turns on when I hit the fire button, and it turns off after sixty seconds. There’s no sleep mode, so unlike the DNA chips, there’s no delay while the device “wakes up.” Pressing and holding both wattage adjustment buttons locks the device, and the same process unlocks it.

The batteries are accessed by removing the back panel, which is secured by magnets. This is a nice touch, as screws can be stripped by daily removal. It’s got a spring-loaded firing pin, which solves one of my biggest gripes with many regulated devices (especially the damnable MVP).

This bridges the gap between mechanical mods and older regulated mods, and it really outperforms both.
