You're probably right, still figuring this stuff out as I go. I figured Tesla was a safe OEM bet over most of the questionable chargers I was looking at on Amazon.
I do remember going through that same thing. I had no way of charging up at home and I was busy getting bids from electricians on wiring my garage. There were two ChargePoint Level 2 chargers in the neighborhood, so I registered with ChargePoint (and my homeowner's assn), but I never yet had to use them. And the car was brand new too. So yeah, I was a bit overwhelmed by all those different Level 2 chargers for sale at widely different prices.
The key is learning what amperage your car can handle for the fastest charging. My car must have 48 amps and can easily handle up to 50 amps. Lower amperage is OK but slower. I'd guess your Ioniq might be the same.
Many of those less expensive Level 2 chargers deliver less juice than that … as low as 24, 32, 40 amps. For me those cheaper chargers were not worth it. The Volvo dealer offered a deal on a ChargePoint charger that could do the job as I needed it. And it was available fast – so I got it. When the electrician did his work on my circuit breaker & in my garage, I asked if he would also install the charger. No problem, he was happy to do it.
Many of those chargers have software to control the charging process. They could also vary the amps delivered to your car, as required. Other models don't seem to have that software or flexibility. I chose the more costly ChargePoint charger because I didn't yet know what my car needed, and because it was "smart", it could vary the amperage up to 48. I didn't really need that extra software. All EVs have that kind of software built into their computers. So, I probably over paid for that charger. At least, it does work well without any problems.
If I only knew then what I know now
