The Chevy Bolt has quietly gone through three different onboard AC charger specs since 2017, and GM’s 2025-announced revival changed the charging port on top of that. Buying a charger without checking which Bolt is in the driveway means either overpaying for amperage a pre-2022 Bolt EV can’t use, or under-buying for a car that could charge twice as fast. The connector matters too — every Bolt through the 2023 model year used J1772, but the returning 2027 Bolt switched to a native NACS port, GM’s first Chevrolet to do so.
Chevy Bolt onboard charger specs by generation
| Bolt generation | Onboard charger | Connector | Breaker needed |
|---|---|---|---|
| 2017-2021 Bolt EV | 7.2 kW / 32A | J1772 | 40A |
| 2022-2023 Bolt EV / Bolt EUV | 11.5 kW / 48A | J1772 | 60A |
| 2027 Bolt (revived) | 11.5 kW / 48A | NACS (J3400), J1772-to-NACS adapter included | 60A |
A charger rated above what your Bolt’s onboard hardware accepts doesn’t hurt anything — the car simply draws what it can — but it’s money spent on capacity you can’t use. A charger rated below your Bolt’s ceiling caps your charging speed no matter how fast the car itself could go.
1. ChargePoint Home Flex — Best for 2022-2023 Bolt EV/EUV and the 2027 Bolt
ChargePoint Home Flex
- Hits the full 11.5kW/48A ceiling of the 2022-2023 Bolt EV/EUV and the revived 2027 Bolt — either model charges as fast as its onboard hardware allows.
- Sold in both J1772 and NACS versions; take NACS for a 2027 Bolt to skip the included adapter entirely, or J1772 for a 2022-2023 Bolt.
- See our full ChargePoint Home Flex review for the breakdown of all six hardwired-vs-plug-in configurations.

2. Autel MaxiCharger AC Wallbox — Best Budget 48A Pick
Autel MaxiCharger AC Wallbox
- Matches the same 11.5kW ceiling as a 2022-2023 Bolt or 2027 Bolt's onboard charger, usually cheaper than the Home Flex.
- Color touchscreen works standalone without pairing a phone app first.
- Read our full Autel MaxiCharger review for how it stacks up against ChargePoint on price and features.
3. Grizzl-E Classic — Best Value for a 2017-2021 Bolt EV
Grizzl-E Classic
- Comfortably covers a pre-2022 Bolt EV's 7.2kW/32A onboard charger without paying for 48A capacity that car can't use.
- NEMA 4 cast-aluminum enclosure handles an outdoor garage-adjacent mount with no extra weatherproofing.
- Not the right pick if the same household later adds a 2022+ Bolt or another 48A-capable EV — this unit's output is fixed at 40A. See our full Grizzl-E lineup review for the Classic Connect and other tiers that go higher.
Should you buy GM’s own PowerUp 2 charger?
GM sells its own NACS home charger for the 2027 Bolt lineup, the PowerUp 2, at 11.5kW/48A for $899 — or bundled with cables and adapters as the PowerUp Charging Package for $1,155. That’s roughly $350 more than a ChargePoint Home Flex NACS at the identical 48A output, for a Chevy-branded box built by the same class of third-party charger manufacturers this guide already covers. Unless the bundle’s extra adapters genuinely save you a separate purchase, the third-party 48A pick above delivers the same charging speed for less.
A note on the 2017-2022 battery recall
Anyone shopping a used 2017-2022 Bolt EV or EUV should know GM issued a series of recalls starting in 2020 over a battery-cell manufacturing defect that created a fire risk, eventually covering every Bolt through the 2022 model year. GM’s fix was a full battery pack or module replacement, and completed replacements carry their own fresh 8-year/100,000-mile battery warranty — a car that’s already had the recall work done is considered resolved, but it’s worth confirming the recall was completed before buying used. This has nothing to do with which home charger to buy; it’s a car-side check, not a charger-side one.
The bottom line
Check the model year before buying a charger. A ChargePoint Home Flex — NACS for a 2027 Bolt, J1772 for a 2022-2023 Bolt EV/EUV — matches the 11.5kW onboard ceiling both share. A 2017-2021 Bolt EV only needs the Grizzl-E Classic at 40A, since its 7.2kW onboard hardware never asks for more. Whichever charger you pick, our EV charger installation cost guide covers what the electrical work runs, and our NACS vs J1772 guide breaks down the connector switch in more detail if the 2027 Bolt’s new plug is what brought you here.
