The generator can deliver up to 20Vpp. You can get 40Vpp if you combine the two Outs. I have had a gen set to 20 Vpp almost nonstop 24/7 for more than two years without issues. But it is not the same 20Vpp with remote mode than 20Vpp with handheld electrodes, or 20Vpp with huge tens pads, or 20Vpp doing Colloidal silver. Each of them draw a different intensity (milliamps) while at 20Vpp, being the last one the most demanding by far (almost shortcircuit).
