This VVPS can control more than one vape at a time, with each channel controlled independently with its own knob. This VVPS requires a separate power supply to feed it power, sold separately, and can only lower the voltage, not raise it higher than the power supply can provide. You will need a 12 or 15 volt power supply with sufficient amperage to power your vapes, a center-positive 2.1mm barrel plug and DC (not AC) voltage. A good rule of thumb is at least 1 amp for each vape. ie: Running two vapes at once would require a 2A power supply. Using a power supply that puts out more than 15v will immediately damage your VVPS. If you have any doubts about your set up, please contact us first.
Each VVPS unit comes with (2) three-foot extension cords per channel. So a 2-channel VVPS will include 4 extension cords, so that you have spares.
Please read our voltage guide as fire, or damage to your vape, can occur when using more than 12v.
