Charger Failed After Two Days, Support Unhelpful
This Level 2 EV charger was installed on a new dedicated circuit with the help of an electrician. It worked for two days, then began shutting down after each charge and displaying fault indications. The electrician rechecked the installation and contacted the manufacturer's technical support, who reportedly said this happens often and offered to send a replacement unit in hopes it would work. The experience was unsatisfactory.
Cons
- − Stopped working after two days
- − Shuts down after each charge
- − Displays fault indications
- − Manufacturer support acknowledged frequent occurrence
- − Replacement offered without guarantee

Duo Charger Works After Fixing Factory Setting
The Duo charger allows charging two vehicles without moving the cable, which is convenient. However, initial setup for internet connectivity failed despite following all troubleshooting steps, including 2.4 GHz-only instructions. The full manual's web browser login method also did not work because the unit would not reboot to save settings. The issue was traced to the OCPP setting being off by default, preventing any connection. After enabling OCPP and saving, the unit rebooted, connected, and downloaded a firmware update. The factory default setting seems counterintuitive and may affect other units.
Pros
- + charges two vehicles without moving cable
Cons
- − internet connection problems out of the box
- − OCPP disabled by default
- − troubleshooting steps did not work

OCPP Access Now Costs Extra
Running a personal Open Charge Point Protocol server with this charger is no longer free. OCPP access was free until Fall 2025, when a $300 CAD fee was introduced. On 6/15/26, the Premium Service fee doubled to $600 CAD. The charger was returned, and no further Grizzl-E products will be purchased due to what is described as bait-and-switch tactics. Not recommended for those who intend to use their own OCPP server.
Cons
- − OCPP access no longer free
- − $300 CAD fee introduced in Fall 2025
- − Fee doubled to $600 CAD on 6/15/26
- − Described as bait-and-switch
