HFTAC-9kW-S18
HFTAC-9kW-S18 is a Level 2 home EV charger from HFT with up to 40 A (9.6 kW) output and a J1772 connector — 24 ft cable, non-networked operation.
Our take
A certified standby draw of exactly zero watts — a figure only a couple of the 56 models in the 40 A class manage, against a 2.38 W median that compounds to about 21 kWh a year on a typical unit. This one is offline, so there is no radio to keep awake, and the idle math simply disappears. Charging is class-standard: 9.6 kW on a 50 A circuit adds roughly 34 miles of range per hour, and 25 of our 29 tracked EVs accept the full rate. The 24 ft cable sits on the cohort median.
- Best for: Buyers who want the charger drawing literally nothing between sessions.
- Trade-off: No networking — the zero-idle figure comes partly from having no electronics to feed.
