The box mod has a new form factor and is larger than the RX200, RX200S and RX2/3 to allow for the additional battery. There are two versions available: the first is made from the same aluminum alloy as preceding mods and the second features a premium and more expensive carbon fiber finish. Both varieties are available in black or silver and there’s also changeable stickers to alter the mod’s look according to your preference.

The top of the RX300 has a stainless steel threaded 510 connection with a spring-loaded center pin in order to easily accept most atomizers. With the Jaybo logo, the fire button looks the same and so do the adjustment buttons at the bottom of the control face. The device is also built with the familiar 0.96″ OLED, but the vertical oriented menu has been rearranged. On the display, you’ll see the mod’s statistics that include current mode, wattage, temperature, voltage, amperage and more. Unlike preceding mods, current wattage or temperature are displayed within a half-circle, giving the menu an amazing look. At the bottom of the menu, there’s also individual battery level indicator bars that monitor voltage levels for each inserted cell.


The mod utilizes four 18650 high rate batteries to ensure it can effectively provide up to 300 watts for long periods of time. For easy access, the battery bay door mechanism looks to be similar to its predecessors. To remove/insert cells, simply pull off the battery door that is held down by powerful magnets. Or, if you prefer to top off the cells while they’re in the device, you can plug it into any USB wall/computer via the micro USB port on the control face.

While previous RX devices had problems with balanced charging and ensuring cells reached optimum voltage, we are hoping that Wismec has fixed these issues with the Reuleaux RX300. Of course, it is always advisable to charge batteries externally. Best of all, the mod can also be used as a power bank for charging your mobile phone in case of emergencies.

From a technical perspective, the RX300 looks to be identical as other RX mods, but with a higher power output. The mod’s wattage ranges from 1 watt to 300 watts and is capable of low resistance down to 0.05ohm. Temperature mode is possible from 100 to 300 Celsius with all types of coil heads including stainless steel, nickel and titanium. Although it is not listed in the specifications, the RX300 is sure to have a TCR mode, so it can be vaped with any number of coil types with very precise output.

Firmware is also upgradable in case a new operating system comes out that may have new features such as higher power output or a new menu. And, the device seems to have a wide range of safety features including reverse polarity protection, overheat protection, low/high resistance protection, low voltage protection and anti-reverse circuit protection. Overall, the RX300 mod looks like it’s going to as popular as its predecessors because of its design, low cost, high power output and state-of-the-art technology. In addition to the mod, you’ll also get a USB cable, a manual, a warning card, an authenticity card and a warning card.
