Description - San Indonesia X Gerobak S101 Box Mod

Introducing the San Indonesia X Gerobak S101 Box Mod

The San Indonesia X Gerobak S101 is a regulated single-battery box mod built around two things: tactile control and consistent power. A collaboration between Gerobak Vaper and San Indonesia, two well-regarded names from the Indonesian boutique mod scene, the S101 takes a deliberately analogue approach to wattage adjustment. Instead of a screen and button cycling, you get a potentiometer dial that sets output smoothly and continuously up to 101W across a 2.0-8.0V range.

Backing that dial is a YiHi chipset, a premium component that keeps output stable and regulated throughout the battery's charge cycle. The compact aluminium alloy chassis accepts 18650, 20700 and 21700 external cells, giving you real flexibility in battery choice. At 40.5 x 27 x 92.4 mm, it fits comfortably in a pocket. Available in Black and Gunmetal, with swappable side panels for personalisation.

This is a mod built for intermediate to advanced vapers who want tactile, no-menu control in a carry-friendly form factor. Free UK delivery on orders over £50, same-day dispatch available on weekday orders placed before 1:00 PM, and every device is covered by a full 1-year warranty in line with UK consumer law.

Why Choose the San Indonesia X Gerobak S101 Box Mod?

The S101 offers something increasingly rare at this price point: a genuinely premium chipset, a distinctive control format and boutique collaborative hardware in a single package. Here is what that means in practice.

• Device style: Regulated single-battery box mod with potentiometer dial control. No screen, no button cycling. Adjust output by twisting the dial directly for smooth, continuous wattage setting.
• Battery and power: Accepts 1 x 18650, 20700 or 21700 external cell (not included). An 18650 adapter is included in the box. Output reaches up to 101W across a 2.0-8.0V range. A 21700 cell delivers the best session length, typically 4000mAh or above.
• Key features: YiHi chipset for accurate, stable output regulation. Centre RGB LED for at-a-glance battery status. USB-C charging with cable included. Multiple built-in safety protections covering short circuit, over-discharge and overheating.
• Target vape style: Best suited to MTL (mouth-to-lung, a tighter draw similar to a cigarette), RDL (restricted direct lung, a slightly more open draw) and compact DTL (direct lung, drawing vapour straight into the lungs with open airflow) setups depending on your tank and coil choice.
• Ideal for: Intermediate to advanced vapers who prefer tactile wattage control over digital menus. Enthusiasts who value chipset quality and build materials. Daily carry vapers who want a compact, capable mod without unnecessary complexity.
• Build quality: Aluminium alloy chassis with compact dimensions of 40.5 x 27 x 92.4 mm. Customisable side panels for cosmetic personalisation. Standard 510 connection compatible with tanks and atomisers up to 26mm for a flush fit.

The S101's combination of a trusted chipset, a distinctive control format and multi-format battery support gives it a practical edge over similarly priced digital mods that rely on cheaper internal components.

Compatibility & Performance

Getting the most from the S101 starts with matching your battery, atomiser and e-liquid to your intended vape style. Here is everything you need to pair it correctly.

• Battery compatibility: Supports 18650, 20700 and 21700 external cells. The 21700 format is recommended for longer sessions given its higher capacity. An 18650 adapter is included, so you're covered if that's what you already own. Always use high-drain cells with undamaged wraps. A high-drain cell is one rated to handle the continuous current draw that higher-wattage mods demand. Shop 21700 batteries or browse 18650 options.
• Compatible atomisers: The standard 510 connection accepts tanks, RDAs and RTAs up to 26mm in diameter for a flush fit. Anything wider than 26mm will overhang the mod body. Browse sub-ohm tanks, RDAs or RTAs to find a compatible pairing.
• Suitable e-liquid types: High-VG shortfills (70VG/30PG and above) suit cloud-forward DTL setups. 50/50 e-liquids work well for MTL and RDL builds with tighter coils. Explore shortfills or browse high-VG e-liquids.
• Wattage guidance: Sub-ohm coils in the 0.2-0.5 ohm range typically perform well between 40-80W. MTL coils running above 0.5 ohm usually suit a lower range of 10-30W. Start at the lower end of the range for your coil type and adjust the dial in small increments until you reach your preferred balance of flavour and vapour production.
• Output stability: The YiHi chipset maintains regulated output rather than drifting as the cell drains. Budget chipsets often produce inconsistent wattage as battery voltage falls, which can affect flavour and vapour quality. YiHi's regulated delivery addresses this directly.
• Charging: USB-C port with cable included. Charging speed is not specified by the manufacturer. For best results and battery longevity, charging external cells on a dedicated charger is recommended. Browse battery chargers.

Knowing your battery format and coil resistance before you start means you'll get the most from the S101 from the very first session, with no wasted coils or unnecessary trial and error.
