AUTEL Maxi US AC W12-H
AUTEL Maxi US AC W12-H is a Level 2 home EV charger from AUTEL with up to 50 A (12 kW) output and a J1772 connector — 25 ft cable, networked smart charging.
Our take
The most efficient of the AUTEL 50 A variants at idle: 3.21 W, a touch under the 3.47 W class median, or about 28 kWh a year. Beyond that it is the familiar 50 A package — 12 kW, 65 A circuit, 25-foot cable, Wi-Fi connectivity shared with 85% of the 20-model cohort. The practical question with any 50 A unit is whether your panel has room for a 65 A breaker; if it does not, a 40 A charger delivers nearly the same real-world charging for a much easier install.
- Best for: Panels with genuine spare capacity for a 65 A circuit.
- Trade-off: Requires a 65 A breaker to deliver an advantage most EVs cannot use.
