The Yihi SXMini MX Class is a groundbreaking device for Yihi. Unparalleled performance, surgical precision, and energy efficiency are just a few key features making this mod on top of your single-18650 box list.

The Yihi SXMini MX Class is powered by the SX480J-BT chipset. The mod is so smart, you can even use your phone to make adjustments.

Fit and finish is superb, seamless and well-built. Furthermore, the MX Class is designed for years of repetitive use. Yihi poured their heart and soul into making a single 18650 work overtime. Additionally, you will find that although there’s only one battery, somehow that single cell pumps out more energy than some dual 18650 boxes. That’s due to Yihi’s prowess in engineering. Making the most out of the one battery and giving you extra juice when you need it most.

A magnetic battery door, on-screen full curve adjustment, 5-way memory for SXi-Q output curves, and a quadrant-based display will make you fall in love all over again. Experiment to your heart’s content with TCR, use nickel or titanium, or even 304, 316, and 317 stainless steel wire. You have one of the best TC controls in the industry with the MX class, with both joule and degree-based output.

The Yihi SXMini MX Class also has a multi-way analog adjustment key that’s shaped like a tiny control stick. This is your control center, with two adjustment keys for a simple yet reliable input method. A solid stainless steel 510 that’s one of the most durable ever construction is mated to a robust zinc allow that will serve your vape needs for years to come.
