One DigiNow charger will draw 16A when connected to 120V, and 32A when connected to 240V.
The DigiNow Charger isn't an EVSE compatible charger, an EVSE it's just an electrical outlet that can tell to a charger what is the maximum power that can take from it without tripping the breaker, the EVSE compatible charger is the one that it's adjusting to the power available from the EVSE, the DigiNow Chargers are not communicating with the EVSE, relaying on the operator to only plug it in the appropriate ( power wise ) outlet, this is making the system more simple, and you can connect it to a variety of outlets, without having to buy an EVSE box/cord.
