In the last two years, Sigelei has released some interesting mods and tanks. Some of them have been impressive, but some of them have fallen short of what we started to expect from the brand, Of course, many of us who are familiar with Sigelei have probably begun to compare their other devices with the powerhouse Fuchai mods, such as the Sigelei Fuchai R7 230W Box Mod. A recent mod release? The Sigelei GW 257W TC Box Mod, which is aptly named GW after the Great Wall of China. Although there are mixed opinions about the Sigelei GW 257W TC Box Mod, all in all, the mod functions beautifully, minus a few little quirks. Keep reading for 3 pros of the Sigelei GW 257W TC Box Mod that make the “Great Wall” a stand-out mod.

1. A Dual Battery Mod That Uses 18650, 20700, or 21700 Batteries

Most of the mods on the market use the standard 18650 batteries. But it’s always great to see a mod that gives you the option. The Sigelei GW 257W TC Box Mod comes with an 18650 battery adapter, so if you’ve only got 18650s, you don’t need to sweat it. However, the ability to utilize 20700 or 21700s means that you can get more charge out of your mod. You can easily vape with the Sigelei GW 257W mod for a full day with these batteries and the charge lasts! Long battery life equals more power vaping? Yes.

2. The Sigelei GW 257W TC Box Mod Can Reach Up To 257W

Most of us don’t stray farther than the 100W range, but those of you who love cranking up the power will certainly be glad that the GW allows you to reach those higher wattages. Vaping the Sigelei GW 257W TC Box Mod, I have had no issues with firing response time, navigating the menu, or weird shortages and misfires. The chipset is fast and reliable.

3. The 510 Connection and the Broad, 36mm Depth of the Mod

If you’re looking for a smaller, more compact mod then the Sigelei GW 257W TC Box Mod is certainly not for you. However, if you don’t mind your mods bulkier, you’ll be pleased with the 36mm depth on the Sigelei GW. No matter what sort of atomizer you wish to place on the mod, most fit nice and tight with no overhang. That means that even your larger RDAs should fit on the mod seamlessly.

Think the Sigelei GW Mod Might Be For You?

If you’re mainly a power vaper, the Sigelei GW 257W TC Box Mod does really well. No misfiring, no issues to speak of. The TCR and TC modes function very well also, with the exception of an occasional misfire or lag (not a big deal unless you make it one). Keep in mind that this mod is large. Like the Great Wall of China, this thing is sizable. However, it still manages to feel ergonomic despite the size. The placement of the firing button (the button in the top middle section cleverly branded “Sigelei”) may be a bit awkward if you aren’t used to it, but it’s responsive. The screen on the GW is sort of small, especially considering the size of the mod. It’s also a vertical display, which is very strange. If those little design quirks won’t bother you, the Sigelei GW 257W TC Box Mod really is a hard-hitting device.
