How to Choose the Right Home EV Charger

1. What power supply do you have?

Single-phase power suits a charger of about 7 kW; three-phase allows up to 22 kW. If you're not sure, a licensed electrician can tell you. See single-phase vs three-phase charging.

2. Do you have solar, or plan to?

If you want to charge from excess solar, choose a charger that does it out of the box or with a supported add-on. See solar EV charging.

3. What can your car accept?

Every charger we sell uses the Type 2 connector, so check your car has a Type 2 port. Then check its maximum AC charging rate: there's no speed benefit in a charger more powerful than your car accepts.

4. Tethered cable or socket?

A tethered charger has its cable permanently attached: unhook it and plug in. A socket (untethered) charger needs your own Type 2 cable, which keeps the wall tidy and lets you choose the cable length. The Evnex X22, myenergi zappi and Smappee EV Wall come in both; the Evnex E2 range and myenergi zappi GLO are tethered.

Connection options and cable lengths
Charger	Options	Cable length
Evnex E2 Flex	Tethered	5 m
Evnex E2 Core	Tethered	5 m
Evnex E2 Plus	Tethered	8 m
Evnex X22	Tethered or socket	5 m (socket: your own cable)
myenergi zappi	Tethered or socket	6.5 m (socket: your own cable)
myenergi zappi GLO	Tethered	6.5 m
Smappee EV Wall	Tethered or socket	8 m (socket: your own cable)

5. Where will it be mounted?

Measure from where the charger will go to your car's charging port, allowing for how you park, and choose a cable long enough to reach comfortably. If the charger will be outdoors, check the manufacturer's installation requirements. The Smappee EV Wall is rated IP54 and IK10 for indoor and outdoor use. You can preview any charger on a photo of your wall with See It On Your Wall.

6. How will it connect?

App control, scheduling and solar features rely on a connection. If Wi-Fi is weak where you park, look at chargers with 4G or Ethernet.

Connectivity by charger
Charger	Connectivity	App
Evnex E2 Flex	Wi-Fi	Evnex app: start, stop, track costs
Evnex E2 Core	Wi-Fi	Evnex app: start, stop, schedule, track costs
Evnex E2 Plus	Wi-Fi and 4G	Evnex app: start, stop, schedule, track costs
Evnex X22	Wi-Fi, 4G and Ethernet	Evnex driver app
myenergi zappi	Wi-Fi and Ethernet	myenergi app
myenergi zappi GLO	Wi-Fi and Bluetooth	myenergi app (no screen)
Smappee EV Wall	Ethernet and 4G (2 years included)	Smappee app

7. One EV or more?

If you'll run more than one charger, or your home's supply is tight, load management shares or limits the power so you don't overload it.

Load management by charger
Charger	Load management
Evnex E2 Flex	Home overload protection
Evnex E2 Core	Home overload protection
Evnex E2 Plus	Overload protection, plus load balancing between E2 Plus chargers
Evnex X22	Overload protection, plus load balancing between chargers
myenergi zappi	Optional limit on current drawn from the supply
myenergi zappi GLO	Not specified by myenergi
Smappee EV Wall	Static overload protection; dynamic load balancing
