Owners can test a tethered charger with inspection, indicators and a short supervised charge. Instrument testing belongs to a qualified electrician.

The name comes from how the cable is used: a slow charger kept for visits to homes with no charger, classically granny’s. Here is whether one is any good.

Often not: UK chargers with built-in PEN fault protection usually need no earth rod. Without it, an earth electrode is the other compliant route.

Yes. Smart home chargers can be locked with an app, PIN or RFID card, and cables, connectors and the unit itself can be secured physically too.

An 11kW onboard charger is the converter inside the car. It sets the fastest AC charging the car can accept, and it needs a three-phase supply to reach 11kW.

Yes: a plug-in charger unplugs and travels with you. A hardwired unit needs an electrician at both houses and a new circuit at the new one.

Most Level 1 chargers draw 12 amps continuously from a 15-amp, 120-volt circuit. On a 20-amp circuit, some draw up to 16 amps.

A Level 1 charger is a portable cable with a household plug, an in-cable control box with status lights, and a J1772 or NACS connector for the car.

A mobile connector is the portable charging cable (EVSE) that plugs an EV into a standard outlet. Its parts, speeds, and how it differs from a wallbox.

A 32 amp charger delivers 7.7 kW at 240V (about 7 kW single-phase on Type 2), enough to restore around 60 kWh overnight. Here is the maths.
