Most “best charger for X EV” roundups on this site split by trim — different amperage, sometimes a different connector generation to generation. The BMW i4 is the simplest case yet: every trim built so far shares one onboard charger and one connector, full stop.
BMW i4 onboard charger and connector, by trim
| Trim | Onboard charger | Home AC connector | Breaker needed |
|---|---|---|---|
| i4 eDrive35 | 11 kW / 48A | J1772 (CCS1 port) | 60A |
| i4 eDrive40 | 11 kW / 48A | J1772 (CCS1 port) | 60A |
| i4 M50 | 11 kW / 48A | J1772 (CCS1 port) | 60A |
Per BMW USA’s own home-charging and NACS FAQ pages, every 2022-2026 i4 ships with a “Flexible Fast Charger” and a NEMA 14-50 adapter standard, and the car’s CCS1 port physically accepts J1772-pin AC charging with no adapter. BMW confirms native NACS ports are coming with the 2027 model year — not the current i4 — and that the 2026 i5 M60 is the first BMW with a native NACS port, limited to that one trim. In other words: don’t buy a NACS charger for a current i4 expecting to skip an adapter later; if you want Tesla Supercharger access on a 2022-2026 i4, that runs through a separate Remote Software Upgrade plus a DC adapter, unrelated to which Level 2 home charger you buy.
1. ChargePoint Home Flex — Best All-Around Pick
ChargePoint Home Flex
- Matches the 11kW/48A onboard charger every current i4 trim shares — no wasted capacity, no bottleneck.
- One connector to buy, since every i4 through 2026 uses J1772 — no version mix-up risk like on brands mid-NACS transition.
- See our full ChargePoint Home Flex review for the breakdown of all three hardwired-vs-plug-in configurations.

2. Autel MaxiCharger AC Wallbox — Best Budget Pick
Autel MaxiCharger AC Wallbox
- Same 48A ceiling as the Home Flex at a lower price — no compromise on charging speed for an i4's 11kW charger.
- Read our full Autel MaxiCharger lineup review for how this tier compares to the step-up AC Pro.
3. Grizzl-E Classic 40A — Cheapest Option
Grizzl-E Classic 40A
- Cast-aluminum, NEMA 4 outdoor-rated build at the lowest price of the three — no smart features, no app, just a plug and a cable.
- Caps at 40A rather than the full 48A an i4's onboard charger can use, so it's a small step down in overnight charging speed — worth it only if the price gap matters more than the last stretch of range recovery.
- See our full Grizzl-E lineup review for the tiers that go all the way to 48A and beyond.
The bottom line
Every current BMW i4 trim shares the same 11kW/48A onboard charger and the same J1772/CCS1 port, so this is one of the rare brand-capture picks on this site with no connector decision to make — the ChargePoint Home Flex matches that 48A ceiling exactly and is the safest all-around buy. Save for the Autel MaxiCharger if budget matters more than the extra configurability, or the Grizzl-E Classic if you just want the cheapest box that gets the job done.
