Product introduction

WISMEC Reuleaux RX300 Mod is the modular evolution of the RX200 and RX200S. Heralding in the new generation of RX devices, it is the first Wismec platform to utilize a four high amperage 18650 battery configuration, providing unprecedented battery life and a whopping 300W of true maximum power. With an atomizer resistance range of 0.1 to 3.5 ohms and a 50A maximum output current rating, the RX300 is capable of easily handling practically any atomizer requirement needed. Full temperature control capability is also on board, with Ni200 Nickel, Titanium, Stainless Steel and TCR modes available with a range of 200 to 600℉. In temperature control mode, it features an adjustable TCR mode that allows for expanded compatibility and output tuning. At last, the 0.96" intuitive OLED screen displays a classic and effective organization, with essential information neatly shown along with separate battery bars evaluation. 2 colors to choose from.

its a really nice mod works great. its heavy with 4 batteries but gives good working times last me about 12 hours but im a heavy user and run it around 120 watts with a t10 coil. and its taken a lot of punishment being dropped a bunch of time but its still working fine.

Overall the mod is pretty nice. It's a bit bulky and has a good amount of weight with 4 batteries.

The only issue I have had is when it first arrived I had to dismantle the device and adjust the wire that is soldiered to the center pin because it was shorting against the wire that connects to the threads.

Side note: any of the Tfv beast tanks tent to have slight connection issues with this mod. After some adjustments my Tfv 8 with the rebuildable deck works great on this mod.

Definitely a solid 4 *'s before firmware upgrade.

It is not recorded in Hangul either.
I wrote it again.
I was surprised because it was lighter than I thought.
It's because it weighs the shell.
It is quite heavy to put the battery in the picture.
The weight felt is similar to the 3 battery device primus koopor.
The user interface should be touched if you do not know the existing devices.
It is recommended that four batteries are used.
When using MTL, battery consumption is low, but it pushes to a huge concentration.
Satisfied with low prices and satisfied with the strong performance.
