Since 2017 the Chevy Bolt has carried three different onboard AC charger specs, and GM's 2025-announced revival altered the charging port as well. If you purchase a charger without confirming which Bolt you own, you either overpay for amperage a pre-2022 Bolt EV can't use or under-buy for a car that could charge twice as quickly. Connectors differ too: J1772 was used on every Bolt through the 2023 model year, but the returning 2027 Bolt has a native NACS port, the first on any Chevrolet from GM.

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 |
Nothing is harmed when a charger is rated higher than your Bolt's onboard hardware accepts, since the car just draws what it can, but you have paid for capacity that goes unused. A charger rated under your Bolt's ceiling limits your charging speed, however fast the car could otherwise go.
1. WenStorm Level 2 Portable EV Charger — Best Portable Pick (No Install)
WenStorm Level 2 Portable EV Charger
Best Portable Pick (No Install)
- From an existing NEMA 14-50 outlet it supplies up to 32A / 7.7 kW, which closely fits the 7.2 kW / 32A onboard charger in a 2017-2021 Bolt EV.
- Both versions cost $219.99 and carry a 2-year warranty: J1772 for 2017-2023 Bolts, and NACS for the 2027 Bolt.
- Rather than an inline box, the control electronics are in the connector handle, and a 16/24/32A current setting lets you lower output if the circuit behind the outlet is smaller than expected.
- A 2017-2021 Bolt EV accepts 7.2 kW, so 32A / 7.7 kW meets or exceeds it and no capacity goes to waste, and the price is far below the $299.99 Grizzl-E Classic. When you move it comes along, and if a NEMA 14-50 outlet is already installed you need no electrician.
- It is plug-in only, requires a NEMA 14-50 outlet, stops at 32A / 7.7 kW, and offers no app or Wi-Fi scheduling. It leaves speed on the table for the 11.5 kW 2022-2023 and 2027 models.

ChargePoint Home Flex
Best for 2022-2023 Bolt EV/EUV and the 2027 Bolt
- It reaches the full 11.5kW/48A limit of the 2022-2023 Bolt EV/EUV and the revived 2027 Bolt, so either model charges as quickly as its onboard hardware permits.
- Both J1772 and NACS versions are sold. Choose J1772 for a 2022-2023 Bolt, or NACS for a 2027 Bolt so the included adapter isn't needed at all.
- Our complete ChargePoint Home Flex review walks through all six configurations, hardwired and plug-in.

Autel MaxiCharger AC Wallbox
Best Budget 48A Pick
- Its 11.5kW ceiling matches the onboard charger in a 2022-2023 Bolt or a 2027 Bolt, and it generally costs less than the Home Flex.
- The color touchscreen operates on its own, with no need to pair a phone app first.
- Our complete Autel MaxiCharger review compares it with ChargePoint on price and features.

Grizzl-E Classic
Best Value for a 2017-2021 Bolt EV
- It handles the 7.2kW/32A onboard charger of a pre-2022 Bolt EV easily, without making you pay for 48A capacity that car can't use.
- Its NEMA 4 cast-aluminum enclosure copes with a mount outdoors near the garage and needs no added weatherproofing.
- It's a poor choice if your household may later add a 2022+ Bolt or another 48A-capable EV, because this unit is fixed at 40A output. Our full Grizzl-E lineup review covers the Classic Connect and other tiers with higher output.
- Is GM's own PowerUp 2 charger worth buying?
- For the 2027 Bolt lineup, GM sells a NACS home charger of its own, the PowerUp 2, rated 11.5kW/48A at $899, or $1,155 as the PowerUp Charging Package bundled with cables and adapters. Against a ChargePoint Home Flex NACS with identical 48A output, that is about $350 extra for a Chevy-branded box from the same sort of third-party charger makers covered in this guide. The third-party 48A pick above gives the same charging speed for less, unless the bundle's added adapters would spare you a separate purchase. The WenStorm Level 2 Portable is the lower-priced plug-in alternative at $219.99, though it caps at 32A / 7.7 kW.
Check Price →A note on the 2017-2022 battery recall
Buyers eyeing a used 2017-2022 Bolt EV or EUV should be aware that starting in 2020 GM issued a series of recalls for a battery-cell manufacturing defect that posed a fire risk, and the recalls ultimately reached every Bolt through the 2022 model year. GM resolved it by replacing the whole battery pack or modules, and finished replacements come with a new 8-year/100,000-mile battery warranty. A car with the recall work completed is treated as fixed, but confirm that before buying used. This is a check on the car, not the charger, and has no bearing on which home charger to buy.
The bottom line
Start by checking your model year. For a 2027 Bolt take the NACS ChargePoint Home Flex, and for a 2022-2023 Bolt EV/EUV take the J1772 version; both cars share an 11.5kW onboard ceiling that it matches. A 2017-2021 Bolt EV never requests more than its 7.2kW of onboard hardware, so the Grizzl-E Classic at 40A is all it needs. With any of them, our EV charger installation cost guide covers what the electrical work costs, and if the 2027 Bolt's new plug is why you're here, our NACS vs J1772 guide explains the connector switch in more detail. The WenStorm Level 2 Portable ($219.99) is the alternative worth knowing for a 2017-2021 Bolt EV: its 32A / 7.7 kW matches the 7.2 kW onboard charger, and it comes in J1772 or NACS. It has no app or Wi-Fi scheduling and leaves speed on the table for 11.5 kW Bolts, but WenStorm costs less than the other picks.

Frequently Asked Questions
Which home charger suits a Chevy Bolt best?
The answer turns on which Bolt you have. For a 2022-2023 Bolt EV/EUV or the new 2027 Bolt, each with an 11.5kW onboard charger, the best overall choice is the ChargePoint Home Flex (~$549, 48A/11.5kW, configurable), in the NACS version for the 2027 Bolt or a Tesla and J1772 for the rest. A 2017-2021 Bolt EV tops out at 7.2kW/32A onboard, so its owners can spend less on the Grizzl-E Classic (about $299.99, 40A/9.6kW), as the added amperage of a 48A unit would go to waste. A lower-cost plug-in alternative for older Bolts is the WenStorm Level 2 Portable at $219.99.
Is the onboard charger the same on every Chevy Bolt?
They don't; there are three separate generations. The first, the 2017-2021 Bolt EV, came with a standard 7.2kW (32A) onboard charger. Starting with the 2022 model year GM raised it to 11.5kW (48A), standard on the Bolt EV and the new Bolt EUV alike, and kept that 11.5kW rating through the last 2023 models before production paused. GM announced the revived 2027 Bolt in October 2025, and its onboard charger is also 11.5kW, so the figure held steady while the plug changed.
Will a 2027 Chevy Bolt need a NACS charger, or does J1772 work?
GM's first Chevrolet with a native NACS (J3400) charging port is the 2027 Bolt, which replaces the J1772 port used by all earlier Bolts. A J1772-to-NACS adapter comes standard, so it can use a J1772 home charger at no extra cost, though a charger with a NACS connector, such as the ChargePoint Home Flex NACS or Grizzl-E Classic Connect, charges it with no adapter hanging off the handle. The WenStorm Level 2 Portable is also offered with a NACS connector, at the same $219.99 as J1772.
Which breaker size does a home charger for a Chevy Bolt require?
A 48A charger, which suits a 2022-2023 Bolt or the 11.5kW onboard charger of the 2027 Bolt, requires a 60A breaker, while a 32A charger sized for the 7.2kW onboard charger of a pre-2022 Bolt requires a 40A breaker. The reason is NEC 625.41 and 210.20(A), which require continuous-load EV circuits to be sized at 125% of the charger's rated output and not of the car's. A WenStorm Level 2 Portable at 32A needs a 40A circuit and a NEMA 14-50 outlet.
Is GM's PowerUp 2 charger a good purchase for a Chevy Bolt?
It does the job, but compared with third-party chargers of the same output it costs more. GM's PowerUp 2 is an 11.5kW NACS home charger at $899, while a ChargePoint Home Flex NACS with the same 48A/11.5kW ceiling runs roughly $549. GM also offers a PowerUp Charging Package of cables and adapters for $1,155. Unless those extra adapters justify the premium, a third-party 48A charger gives the same speed for less money.
Is the WenStorm Level 2 Portable good for a Chevy Bolt?
For a 2017-2021 Bolt EV it works well, while newer models run into limits. The WenStorm Level 2 Portable delivers 32A / 7.7 kW from a NEMA 14-50 outlet, matching that car's 7.2 kW onboard charger, in J1772 or NACS at $219.99. It has no app or Wi-Fi scheduling, and it charges a 2022-2023 Bolt or 2027 Bolt slower than their 11.5 kW onboard hardware allows.
