Cost to Charge GMC Hummer EV Pickup on Mercedes-Benz HPC

The Hummer EV Pickup's NACS+CCS port plugs directly into Mercedes-Benz HPC stalls — no adapter needed. Check the Mercedes-Benz HPC app before your first session to confirm which connector your target station uses — mixed-connector deployments are common in 2026.

On a session-by-session basis, the Hummer EV Pickup's 350 kW peak charging speed is well-matched to Mercedes-Benz HPC's DC fast hardware. Expect a 10→80% charge in roughly 20 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.

Cost-wise, one $68.06 full charge on Mercedes-Benz HPC represents $0.21 per mile of driving — about 21.4¢/mile. A gas equivalent at 30 mpg and $3.50/gal is roughly 11.7¢/mile, so this charging session is more expensive than gas at current prices. Over 15,000 miles/year, exclusive reliance on Mercedes-Benz HPC would cost roughly $4,013.21/year in fuel — a meaningful delta compared to mostly-home charging (~$1,655.45/year).

For most Hummer EV Pickup owners, the realistic use-pattern for Mercedes-Benz HPC is road trips and occasional top-ups — not primary fueling. If you live in an apartment or condo and rely on public charging as your main option, factor in the per-session pricing with no membership option.
