Sạc xe điện Chargepoint home flex EV.

ChargePoint started in the EV business building public charge stations. The Home Flex represents its expansion into residential, Level 2 chargers.

Home Flex has nearly everything you’ll find in our Best Overall JuiceBox 40, with even a bit more to like. Its box is compact and stylish, and its connector locks into its holster or a charge port with a smooth, authoritative click. The holster is ringed with a softly glowing halo of an LED. More significantly, Home Flex can raise the peak charging rate to 50 amps if it’s hardwired. While that’s almost overkill in a Level 2 charger, given that 40 amps should still charge any EV overnight for years to come, Home Flex will charge a few more current EVs (a couple Teslas and the Ford Mustang Mach E) at their fastest possible rate on residential Alternating Current.

Wired for 50 amps, Home Flex is likely to add some installation cost. Its connector cable is a couple feet shorter than JuiceBox 40’s, and its box-to-outlet cord is shorter, too. Those things can matter, but they’re not what relegate Home Flex to runner-up status, in our estimation. It’s just simple, rational arithmetic. ChargePoint’s Home Flex costs at least $100 more than JuiceBox 40, and that cash would make a significant contribution to whatever installation costs there might be
