Grizzl-E Ultimate 80A vs Emporia 48A: Almost Nobody Needs 80
Short answer
The Ultimate can deliver 19.2 kW, and almost no electric car sold has an onboard AC charger that will accept it. Most top out at 11.5 kW, which a 48 amp unit already provides, and many stop at 7.7 kW. On top of that, an 80 amp charger needs a 100 amp dedicated circuit, which very few residential services can spare without an upgrade.

Choose the Grizzl-E Ultimate, 80 A, 19.2 kW if…
Choose the 80 amp unit only if you have confirmed two things: that your vehicle's onboard charger accepts more than 11.5 kW of AC, which is rare and worth checking in the manual rather than assuming, and that a licensed electrician has confirmed your service can support a 100 amp continuous load. Both conditions have to be true, and for most households neither is.

Choose the Emporia Level 2 EV Charger, 48 A, J1772 if…
Choose the 48 amp unit for almost every home installation. It delivers the maximum most cars will take, it needs a 60 amp circuit rather than a 100 amp one, and the installation is far cheaper and far more likely to be possible without a service upgrade. Buying charger capacity your car cannot use is money spent twice, once on the unit and again on the wiring.

Common questions
Which cars can actually take more than 11.5 kW on AC?
A small number, and it changes by model and year. Some larger trucks and a few premium models have accepted higher AC rates. Check the onboard charger specification in your owner's manual for the exact model and year rather than a general figure, because the same nameplate model can differ between years and between markets.
What does an 80 amp circuit involve?
A 100 amp dedicated circuit with correspondingly heavy conductors, and in most homes that means a service upgrade, which is licensed electrician work and often utility coordination as well. The installation cost calculator on this site gives an idea of the range, and the real number comes from quotes on your specific property.
Does faster charging harm the battery?
Level 2 AC charging at any of these rates is gentle compared with DC fast charging, and manufacturers design for it. What affects battery life more is sitting at very high states of charge and repeated DC fast charging. Setting a daily charge limit below 100 percent is the more useful habit, and your manufacturer's guidance is the one to follow.
How fast is fast enough?
Work backwards from your daily mileage rather than from the charger specification. A 40 amp unit adds roughly 30 miles of range an hour, so an overnight session covers far more than most people drive in a day. The charge time calculator on this site works it out for your car and your commute.
