Verdict

Common Questions
Do I need WiFi for this charger to work?
The charger will charge your car without WiFi, but you lose the real-time energy data and off-peak scheduling that make this model stand out — a stable home WiFi connection is needed to get the full benefit of the app.
How much faster is 48A than a standard outlet?
At 48A this charger adds up to roughly 46 miles of range per hour, several times faster than the 3–5 miles per hour typical of a standard 120V outlet.
Can I use this charger with a Tesla?
This model uses the standard J1772 connector, so Tesla owners need a separate adapter, or can look at Emporia's Tesla-specific charger model instead.
Does this need to be professionally installed?
Yes — it's a hardwired unit, so professional installation is recommended rather than a DIY plug-in setup.
