Cost to Charge Lexus RZ 300e on Tesla Supercharger

The RZ 300e's CCS port may require a CCS-to-NACS or NACS-to-CCS adapter depending on the station. Tesla Superchargers now ship "Magic Dock" CCS support at many sites, and most non-Tesla OEMs are distributing free NACS adapters to owners. Check the Tesla Supercharger 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 Tesla Supercharger'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 $20.97 full charge on Tesla Supercharger represents $0.08 per mile of driving — about 7.9¢/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 Tesla Supercharger would cost roughly $1,477.89/year in fuel — a meaningful delta compared to mostly-home charging (~$677.37/year).

For most RZ 300e owners, the realistic use-pattern for Tesla Supercharger 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.
