The OXVA Xlim 4 is the newest member of the best-selling Xlim family, and it keeps things refreshingly simple. Instead of a screen and exact wattage settings, it gives you three preset power levels and a ring light that shows your battery and power setting at a glance. Inside is a 1600mAh battery, bigger than most slim pod kits, with up to 30W of power. It uses the new Xlim Top Fill UniTech 3.0 cartridge, and it still works with your existing Xlim pods.
