INVADER 2/3 Dimensions: 50*42*85mm/35*42*85mm Material: Zinc Alloy (Die Cast) Cell Type: two/three hi drain 18650 cell (Discharge current should be above 35A) Thread Type: 510 thread Maximum Output Wattage: Two 18650 -240W / Three 18650-360W Output Voltage Range: 3-8V Maximum Output Current: 60A Resistance Range: 0.1-3.0Ohm Input Voltage Range: 6.4-8.4V/9.6V-12.6V Voltage Adjust: I-V level LED Indicator: Blue The Tesla invader looks nice. It has a powerful look about it, like a tank and, to be fair, the build seems solid. There is no screen just a large plastic fire button with a nice solid press and a small LED light strip. Above the LED on the front is a 1-5 point potentiometer. The device is heavy and very comfortable in the hand. I don’t think I have held a device that is so solidly built as this. The device has two battery covers as standard, capable of housing two 18650 batteries or three. With the adjustable battery housing the maximum wattage differs from 240w-360 depending. The housings have vent holes to prevent over heating and the device also has multiple usage protections such as over puff protection. The device doesn’t have a USB port so battery charging has to be external. The potentiometer is very effective and reacts instantly when increasing the voltage. The only problem with this is the efficiency as its hard to turn and there is no accessory to help this, just your rigid nail. PROS High power output. CONS Potentiometer is hard to turn. Running through the settings with an RBA and a low resistance tank and the limited settings cover all areas and requirements. DESIGN The vape production is perfect when using this device and if its slightly weak then twist the potentiometer on the front to crank it up a bit. This gives an unprecedented experience. USABLILITY I would always start low and build up wattage when using this device to avoid coil burn and other unwanted problems. Potentiometer Personally, the device works best with a RBA as once you find your preferred setting the usability is efficient enough to never change the device until you re-coil your tank. When building coils an alternate device is ideal to be able to check the resistance prior to use. Overall the device is well built and has great wattage ranges. Even with limited functions this is a hard-hitting, powerful device and I advise that it is best used by experienced vapers. The LED light gives you slight guidance and will tell you if something is wrong. The device is fool-proof if the instructions are followed and that being said a usage chart comes within the handbook. But for such a simple design, the device is customisable and reliable. VAPOUROUND MAGAZINE ISSUE 11 163
