Grizzl-E Classic vs Grizzl-E Smart
A spec-only comparison using ENERGY STAR certification data. We have not tested either charger; price, app quality, warranty and build quality are not covered.
- Power: both are rated 9.6 kW (40 A), so charging speed is the same on paper.
- Standby: the Grizzl-E Classic draws less with no car connected (0.8 vs 2.33 W), at most about $2.45/yr less (estimate).
- Connectivity: only the Grizzl-E Smart is listed as network-capable (Wi-Fi/app, scheduling, utility programs).
ENERGY STAR carries these as separate certifications. We do not assume they are the same hardware; check the model number.
