Charging Speed

The Siemens VersiCharge Gen 3 wins on raw charging speed with 11.5kW (48A) versus 9.6kW (40A). In practice, this means:

Vehicle BatteryGrizzl-E TimeSiemens Time
60 kWh (e.g., Tesla Model 3)6.3 hrs5.2 hrs
75 kWh (e.g., Tesla Model Y)7.8 hrs6.5 hrs
100 kWh (e.g., Tesla Model S)10.4 hrs8.7 hrs

The 1.9kW difference translates to about 1.3 hours faster on a 75 kWh battery — noticeable but not dramatic for overnight charging.

Important: Most EVs have an onboard charger that caps AC charging speed (typically 11-11.5 kW). If your car maxes out at 11 kW, the Siemens’s extra power won’t help.

Build Quality & Installation

Grizzl-E Classic:

  • Mounting: Plug-in (NEMA 14-50) or hardwired
  • Cord: 24ft — good reach for most setups
  • Outdoor: Rated NEMA 4 — install it in a driveway or carport
  • Warranty: 3 years

Siemens VersiCharge Gen 3:

  • Mounting: Hardwired only — requires an electrician
  • Cord: 20ft — good reach for most setups
  • Outdoor: Rated NEMA 3R — install it in a driveway or carport
  • Warranty: 3 years

Edge: Grizzl-E. The plug-in option means easier DIY installation if you already have a NEMA 14-50 outlet. The Siemens requires an electrician for hardwired installation.

Smart Features

The Siemens VersiCharge Gen 3 has a clear advantage here with WiFi and app control. The Grizzl-E Classic is a straightforward plug-and-charge unit — great if you want simplicity, but no scheduling or monitoring.
