Hey vapers! It seems like the era of single-battery mods is making a comeback. Not to be outdone by the R99 or T99, this time San Indonesia, in collaboration with Gerobak Vapor, has also released the S101 Mod, a single-battery mod with a potentiometric YiHi chip.

The S101 Mod first launched at Vape Fair 2025, which was held on August 30-31. It is currently still in the pre-order stage, so it's understandable if you haven't found this device in all your favorite vape stores yet.

Before you rush to buy it, it's better to read this review until the end. We'll discuss everything from specifications, price, design, to its pros and cons so you can get to know this mod better.

Review of the S101 Mod by San Indonesia x Gerobak Vapor

You must be very curious, what new breakthrough does this S101 Mod offer and what makes it different from other single-battery mods that are currently trending?

Well, the most prominent aspects of the S101 Mod are on two sides: panel customization features and the chipset used. Interestingly, this S101 Mod is the first mod in Indonesia to use a YiHi chip with a potentiometer system.
