Wye Mod – What is it in Vaping?

What is a Wye Mod?

A Wye Mod is a lightweight, high-wattage box mod manufactured by TeslaCigs, named after the mathematical “Y” shape of its perforated chassis. Designed for sub-ohmvaping, it houses dual 18650 batteries and delivers up to 215 W of adjustable power while remaining one of the lightest dual-battery devices on the market. The skeletal frame reduces weight without sacrificing structural integrity, making it ideal for Australian vapers who want pocket-friendly cloud production and long battery life for all-day use.

Technical Details

The Wye Mod utilises a proprietary HW board that offers five modes: Variable Wattage, Temperature Control (Ni/Ti/SS316), TCR, Taste and Memory. Resistance range is 0.1–3.0 Ω in VW and 0.05–1.0 Ω in TC, firing with a 25 ms ramp-up time. The ultra-light ABS/PC blend shell keeps total weight under 90 g without batteries; dimensions are 82 mm × 52 mm × 26 mm. A spring-loaded 510 pin accommodates 25 mm atomisers flush, while gold-plated battery contacts reduce voltage drop. Firmware is upgradeable via micro-USB, and the 0.96″ OLED screen displays individual cell voltage, puff counter, output wattage, and real-time coil wrap resistance. Ventilation slots double as “Y”-shaped cooling channels, preventing heat build-up during chain-vaping sessions.

Usage & Tips

Install married 18650s positive-first, ensuring wraps are intact to avoid shorts. Prime your wick and set initial wattage 20 % below coil rating, working up to taste. If “Check Atomiser” appears, clean the 510 pin and confirm the wire leads are tightly trapped. Avoid over-tightening; the lightweight threads can strip. Store below 45 °C—Australian car dashboards can warp ABS. When firmware updates, use the supplied cable only; generic leads can brick the chipset. Finally, swap batteries at 3.3 V to maintain balanced cells and extend cycle life.

History & Context

Released mid-2017, the Wye series answered vapers’ demand for powerful yet travel-friendly devices. Its honeycomb “Y” design pioneered ultra-light dual-mods, influencing later models like the Vandy Vape Swell and OBS Bat, and remains popular among Australian cloud-chasers seeking a durable, affordable powerhouse.
