The AVP's replacement pod can accommodate a maximum 2ml of e-liquid or salt nicotine. This pod attaches to the device with strong magnetic connections. Filling this pod is simple, locate the silver slot on the bottom and push down with your needle nose button. This allows the recessed metal piece in the coil to open up all in one swift motion. This receding metal piece also acts as a safety precaution and prevents the juice from leaking.
