Ford extended their popular Focus to create a plug-in hybrid vehicle offering supreme economy with the Ford C Max EV Charger. The Ford C Max Energi has a 3.3 kWh battery size, which lends itself well for level 1 or level 2 EV charging. We recommend our level 2 NEMA 14-50 40 amp charger. This provides the fastest charge for your Ford Focus and will also futureproof you for you next EV charger. If you don’t plan on upgrading your EV any time soon, then a level 1 NEMA 5-15 (regular residential plug) will work well. If you plan on upgrading your EV in the future, a level 2 NEMA 40 amp 14-50 or NEMA 6-50 TOTALEV charger will charge this car at its fastest charge rate and will also provide a much faster charger for your next plug-in or pure electric vehicle.
