Hummer EV, Sierra EV
Mobile charging for GMC
Out of charge in a GMC? We bring the charge to you. Because of weight, any tow requires heavy-duty equipment; dispatch confirms capacity first.
Connector
Hummer EV and Sierra EV use CCS1 on current models, with J3400 (NACS) adoption announced for the future.
Charge port
Port location varies by body style and model year. Look for the door marked with the charging symbol or check your owner's manual before calling.
Charging behavior
These are very heavy vehicles with very large packs. Hummer EV can split its pack to accept higher-voltage DC charging on compatible stations; on other equipment speeds vary.
Why GMC drivers call us
- Off-road trips far from charging
- Towing with a heavy trailer
- High-speed highway efficiency much lower than city driving
Connector and port details vary by model year and market. Your owner’s manual is the final word.
