Personally level 1 charger didn't cut it for my needs [For a lot it might be sufficient or the only option]. When we bought the car, took almost 36 hours to fully charge the car. Family doctor was 120 miles roundtrip, with shopping near by added another 15 miles, thats 135 miles. I immediately bought Level 2 Charger. Level 1 charger stays as in the car as an emergency backup.
Ioniq 5 supports 48A on a level 2 at home.
My garage has a 100A subpanel,
I installed my own level 2 charger. Had to do bit of electrical work. to support 48A, Installed a 60A circuit breaker on the subpanel, and hardwired the level 2 charger with a 4 AWG/Guage wire.
Self Installation Total Cost: under $850 [Level 2 Charger + Circuit Breaker + 4 feet Wire + Misc, clamps etc]
My Level 2 charging rate is 11.3 kW/h. I consistently charge the car to 80% around 5 hours or 100% under 7 hours if the car is bone dry [pretty rare].
Something to keep in mind. If you live in an urban city/township area or need permits from town (which is common), you are better off hiring a licensed electrician/professional to do the work. I have seen the cost of level 2 installation can widely range from few hundreds to several thousands, as the wiring is NOT cheap and depends on your current electric situation. Charger costs can be offset if your electric company offers discount [always good to check, mine didnt].
If i get a chance to buy a BEV truck in future, i might add a second level 2 and/or upgrade the system as the trucks have bigger battery and support much higher Amperage. I would like to maximize that.
