Practical Notes: RZ 300e on Mercedes-Benz HPC
The RZ 300e's CCS port plugs directly into Mercedes-Benz HPC's CCS stalls without an adapter. 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 RZ 300e's 150 kW peak charging speed is well-matched to Mercedes-Benz HPC's DC fast hardware. Expect a 10→80% charge in roughly 16 min. Real-world times run 10–20% longer due to charging taper and battery preconditioning.
Cost-wise, one $23.30 full charge on Mercedes-Benz HPC represents $0.09 per mile of driving — about 8.8¢/mile. A gas equivalent at 30 mpg and $3.50/gal is roughly 11.7¢/mile, so this charging session is still cheaper than gas. Over 15,000 miles/year, exclusive reliance on Mercedes-Benz HPC would cost roughly $1,642.11/year in fuel — a meaningful delta compared to mostly-home charging (~$677.37/year).
For most RZ 300e 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. For regular home charging in a specific state, check our home vs public analysis and your RZ 300e state-by-state breakdown.
