The myenergi zappi (7kW / 22kW) supports three-phase charging at up to 22kW, while the Ohme Home Pro is single-phase only at 7.4kW. On the standard UK single-phase supply (95% of homes), both charge at roughly the same speed. Three-phase is only relevant if your property has a three-phase electrical supply.

Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.
