In this guide we will teach you how to refill a cartridge. While you can do this to disposables, it is recommended you use a fresh cartridge on a battery that can go as low as 1.8v (in our recommended below).

• Cartridges (see below for good quality & cost)
• A battery, we recommend the Yocan UNI Pro 2
• Oil Syringes, you can get these here.
• A dry heater with a thermostat. Oil heaters exist, but we throw everything into a dehydrator. The model we use can be found here.

• Savvy Syringe Pressure Holder, made by us, this goes around the top of the syringe so you don't have to hold it while you wait for it to fill with oil. This helps to fill simultaneously for cheap.
• Savvy Heating Holder, made by us, this holds everything as it heats. This plastic is heat-strong.
• Silicone mat, size doesnt matter as you will cut it into squares.
