Charging at 208 volts

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.

The verdict: if the building gives you 208 volts, buy the charger you would otherwise have bought, size the circuit exactly as you would at 240 volts, and expect roughly 13% less power than the number on the box. There is no 208-volt version of a home charger to go looking for, and nothing is wrong with your installation. What matters far more in a shared building is the amperage you are allocated, which is why an adjustable charger is the right choice here.

Where 208 volts comes from

A single-family house is normally fed single-phase at 120/240 volts: two legs 240 volts apart, which is where a dryer outlet and an EV circuit get their 240. Larger buildings are fed three-phase, and the common American three-phase service is 208/120 volts. Any single leg to neutral is 120 volts, exactly as at home -- but any two legs are 208 volts, not 240, because of the geometry of a three-phase system. That is the whole explanation. Your charger is connected across two legs of someone else's bigger service.

This is why the subject comes up in apartment garages, condo buildings, offices, and the ground floor of mixed-use blocks, and almost never in a detached house. Charging in an apartment and best EV charger for a condo cover the other problems those buildings bring.

What it costs you, in kilowatts and miles

Thirteen percent sounds worse than it feels. At 48 amps on 208 volts a car still gains about 27 miles an hour, so a nine-hour night is roughly 240 miles. The Department of Energy's general figure for Level 2 -- about 25 miles of range per hour -- is comfortably met at 208 volts. Charging speed calculator lets you put your own voltage, amps and efficiency in.

What does not change: the circuit

This is the part that surprises people. Breakers and conductors are sized on current, and the current does not change with voltage -- a 48-amp charger draws 48 amps at 208 volts just as it does at 240. So the continuous-load rule gives the same answer either way: the circuit is sized at 125% of the charger's rated current.

A charger draws its rated current continuously, so the breaker is 125% of it: 16 A needs 20 A, 32 A needs 40 A, 40 A needs 50 A, 48 A needs 60 A, 64 A needs 80 A, 80 A needs 100 A. Breaker and wire size.

Which chargers publish a 208-volt rating

Most makers print only 240 volts on the specification sheet, which is not the same as the charger refusing to work at 208 -- Level 2 equipment as a class is built for both, per the Department of Energy. But two chargers on this site state it explicitly, and when a building is involved an explicit rating is worth having in writing:

• Leviton EV480: Leviton publishes 48 A at 208/240 V and quotes 11.6 kW, on a 60 A breaker, with a NEMA Type 3R enclosure and optional RFID access control -- which is a genuinely useful feature in a shared garage. Leviton EV Series review.
• Autel MaxiCharger AC 80A: Autel publishes 208/240 V AC, 60 Hz, single phase, with output adjustable from 6 A to 80 A in the app, plus a card reader and ANSI C12.20 metering. Autel MaxiCharger 80A review.
• ChargePoint Home Flex does not publish a 208 V figure in the datasheet we hold, but it publishes six amperage settings from 16 A to 50 A -- and in a building, being able to match whatever circuit you are given matters more than the voltage does.

If you want access control as well, which is the usual requirement in a shared garage, best EV charger with access control ranks the category.

Chargers for a 208-volt building

Two units whose makers publish a 208/240 V rating, and one chosen for the setting range a building install actually needs. Live Amazon prices with the date they were read.

1. RFID access control

Leviton EV Series 48 A charger (EV480)

Leviton · J1772 · 48 A / 11.5 kW · 18 ft cable

Leviton's hardwired 48-amp EV Series unit: an 18 ft J1772 cord, a NEMA Type 3R enclosure rated -22 F to 122 F, optional RFID access control and ENERGY STAR certification. The EV48W version adds Wi-Fi and the My Leviton app.

What is good

• +Optional RFID access control for a shared or open driveway
• +NEMA Type 3R enclosure rated -22 F to 122 F
• +ENERGY STAR certified, with a long list of published UL standards
• +Pre-attached input cable and mounting hardware included

What is not

• −18 ft cord, shorter than most 48 A units on this site
• −Hardwired only
• −The app is on the Wi-Fi EV48W, not the EV480

Published specifications for the Leviton EV Series 48 A charger (EV480)

Output	48 A, 208/240 V; Leviton quotes 11.6 kW

2. 80 A with an app and access control

Autel MaxiCharger AC 80A

Autel Energy · J1772 · 80 A / 19.2 kW · 25 ft cable

The connected 80-amp charger: 19.2 kW, adjustable all the way down to 6 A from the app, an RFID card reader and a -40 F to 131 F rating. It asks for a 100 A circuit at full output.

What is good

• +19.2 kW, the ceiling of AC Level 2 charging
• +Adjustable from 6 A to 80 A in the app, so one unit fits almost any circuit
• +Built-in RFID card reader, which is rare outside access-control models
• +Published -40 F to 131 F range, the widest of the 80 A units here
• +Long list of published safety standards plus ENERGY STAR certification

What is not

• −80 A continuous needs a 100 A circuit, which most homes cannot spare
• −Derates above 113 F, so a hot garage will not see the full figure
• −Hardwired only, with no plug-in version
• −4G connectivity is an optional extra, not standard
• −Costs far more than the 48 A chargers most households can actually use

Published specifications for the Autel MaxiCharger AC 80A

3. Homes with an uncertain panel

ChargePoint Home Flex

ChargePoint · J1772 · 50 A / 12 kW · 23 ft cable

The most adjustable unit here. It can be set anywhere from 16 A to 50 A, which makes it the one to buy when you do not yet know what your panel will allow.

What is good

• +Six selectable amperage settings from 16 A to 50 A
• +Sold in both hardwired and NEMA 14-50 versions
• +Rated for indoor or outdoor installation
• +The app is mature and does not require a subscription

What is not

• −23 ft is a foot shorter than the longest cables in this group
• −The 50 A setting needs a bigger circuit than most panels have spare

Published specifications for the ChargePoint Home Flex

Maximum output	50 A / 12 kW at 240 V
