TESLA Charging Equipment

Here are some terms used with Tesla charging:

NEMA 14-50R - recommended wall receptacle installed at your home or office to plug in a Tesla UMC / Mobile Connector

J1772 - your Tesla will come with an adaptor to use with public J1772 charge stations. These are sometimes referred to as Level 1 or Level 2.

HPWC - High Power Wall Connector; the Tesla Roadster charge stations, built by Clipper Creek, and called a "TS-90". These units are 70 amp capable at 208-240 VAC with a unique Roadster coupler / plug. Out of production. Can easily be converted to Tesla non-Roadster or J1772 charge stations with a changed of the vehicle plug.

Wall Connector - designed and built exclusively for Tesla in Taiwan for the Tesla Model S, 3, X, Y, Roadster II (the 200kWh one!). These use Legacy J1772 signaling and can be identified by NOT having a place to “hang the plug” in the right side of the unit. Up to 80 amp capable at 208-240-277 VAC, with programmable amperage limit using DIP switches. Commonly referred to as HPWC, even though they are not. These use the Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere.

Wall Connector GEN2 - designed and built exclusively for Tesla in Taiwan for the Tesla Model S, 3, X, Y, Roadster II (the 200kWh one!). These an be identified by having a place to “hang the plug” in the right side of the unit. Up to 80 amp capable at 208-240-277 VAC, with programmable amperage limit using a rotary switch. Commonly referred to as HPWC, even though they are not. These use the Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere.

Destination chargers - these are the public Tesla plug stations using Wall Connectors (original and GEN2) capable of up to 80 amps at 208-240-277 VAC (however, Tesla now discourages 277 volt operation). These are commonly referred to as HPWCs, even though they are not. These use the Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere.

UMC - Universal Mobile Connector, sold with Tesla Roadster with a Roadster compatible plug, as a portable charge cable, 120-208-240 volt capable, at 40 amps. Came with a NEMA 14-50 plug. Uses J1772 signaling. Built in Mentor, Ohio, USA.

Mobile Connector - 40 amp maximum. Commonly referred to as a UMC, uses Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere. Uses J1772 signaling. 120-208-240 volt capable, with automatic selection of 12, 16, 24, 32 or 40 amps with appropriate interchangeable plugs. These use Legacy J1772 signaling. Built in Chihuahua, Mexico by Jabil.

Mobile Connector GEN2 -  32 amp maximum. Uses Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere. Uses J1772 signaling. 120-208-240 volt capable, with automatic selection of 12, 16, 24, 32 amps with appropriate interchangeable plugs. The interchangeable plugs are different than the original Mobile Connector plugs. Built in Chihuahua, Mexico by Jabil.

Supercharger - Tesla DC fast charge equipment, capable of charging vehicle at 120kW (max 365 amps at max 403 volts). These use the Tesla S,3,X plug in North America and Japan, and Type 2 plug elsewhere. Built by Tesla in USA.

Megacharger - Tesla truck “Semi” charge starions with unique plug, capable of up to about 1.5MW DC. Probably 1000 to 1500 volts at up to 1000 to 1500 amps.
