the technical specs are:

Plug-In: No, Hardwired

On/Off Switch: Yes
Stop Button: Yes
Cord Length: 18 Feet
Cord Holder: Integrated, and available Wall Mount
J1772 Dock: Yes
J1772 Light: No
Height: 16 inches

Input Current: 30 Amps
Circuit Breaker: 40 Amps
Input/Output Power: 7.2kW

Networking: Capable with Future Expansion
NEMA Rating: 3R
NRTL Listing: UL
Voltage: 208-240 AC Volts
Bosch Part Number: EL-51253

the exact model number is a hardwired version (according the specs above), which can easily be converted to a plug so no biggie concern continues to be that it's a 30 amp charge rate which requires a 40 amp breaker - and the plugs are 30 amp plugs - which are 24 amp rated continuous load - proper install of this would be a NEMA 14-50 plug with a 40 amp breaker (it's allowed in some jurisdictions) but a 50 amp breaker would be more common/acceptable...

a hardwired 30 amp charger with a 40 amp breaker would be just fine - not sure about a 30 amp plug in however, probably fine, but technically the plugs maximum rate is 30 amps and that is probably not rated for continuous load. EV Brochure_0.pdf

price is fair - new is $455 on amazon

Charger has been sold.

(to person with an older Volt with 3.3kW onboard charger)

Some notes .

We used the above charger with the Nema 10-30p plug to charge a Spark EV with an 3.3 kW onboard charger So it charged at less than 30 amps.

We are currently using the same model charger with a Nema 14-50 plug and its max output on a car with a 11.4kW onbard charger is 30amps. It is on a 40amp breaker. Using another evse on that plug we got upto 32 amps out.

I would recommend going with the Nema 14-50 plug and have that installed if you haven't already. Because of the increased amp's it can handle as mentioned by daveo4Bolt and because many new EV's use the that plug.
