Wismec Reuleaux RX300 300W

Weight: 0.84 LBS

Wismec Reuleaux RX300

Requires 4 High Amp 18650 Batteries

The next generation flagship from Wismec is ready, but are we? Packing in an unprecedented four 18650 batteries, this mod is capable of firing a true 300 watts of power. Larger than previous RX2/3 and RX200, yet still somehow comfortable in the hand and easy to use. To accommodate for the quad battery configuration, Wismec has revised the battery loading mechanism to be located on the bottom of the device with a locking switch. The RX300 still retains the features of the past generation like TCR and support for Ni200, Titanium, SS316, N80, and of course Kanthal A-1. Wismec has also altered the .96 inch OLED screen to include each individual battery life meter, and now shows your current draw from the batteries. Large and powerful is the name of the game with the RX300.

    This thing has a great chipset in it and upgrading and customizing the logos is super easy. With the most recent firmware upgrade the rx300 actually goes from 1W-400W instead of the original 1W-300W!!! (as if 300W wasn't already Waaaay more than enough) overall a good solid mod
