The best 32-amp charger is an adjustable one, and the ChargePoint Home Flex is the cleanest of them: it sets to 16, 24, 32, 40, 48 or 50 amps, so you dial in exactly 32 amps for a 40-amp circuit and can turn it up later if your panel and car allow. If value is your filter, the Emporia Level 2 does the same job for less - its app sets the current in single-amp steps from 6 to 48 amps - and it is our overall pick for most homes.
32 amps is the amperage that fits a lot of homes without touching the panel. On a 240-volt circuit a 32-amp charger delivers 7.7 kW - roughly 20 to 25 miles of range per hour, comfortably more than enough overnight - and it runs on a 40-amp circuit, which many panels can spare where a 50- or 60-amp circuit would need an upgrade. It is also the exact rate a large number of EVs accept: plenty of cars cap their onboard AC charger at 7.7 kW, which is 32 amps, so a bigger charger would not charge them any faster. The catch is that almost no charger is sold as a fixed "32-amp" unit. The right way to get 32 amps is an adjustable charger set to 32 - and this page ranks the ones that do it well. We compile published manufacturer specifications and the wiring math; we do not run a test lab.
The short version
Every pick here is a charger whose amperage you set, and every one can be set to 32 amps. Here is how they split:
- ChargePoint Home Flex - best 32-amp pick overall. Selectable at 16, 24, 32, 40, 48 or 50 amps, so 32 is a clean, documented setting, tied into the biggest public-charging app in North America. Full ChargePoint review.
- Emporia Level 2 - best value, and best for most. The app sets the charge rate in single-amp steps from 6 to 48 amps, so you can land exactly on 32 - plus real energy monitoring, at the lowest price here. Full Emporia review.
- Grizzl-E Ultimate - best rugged pick. Adjustable 16 to 48 amps in a cast-aluminum IP67 shell, UL certified - the toughest box here, and the one to hardwire on a 40-amp circuit and forget. It is the big brother of the Grizzl-E Classic.
- Autel MaxiCharger - best features. Its output is app-adjustable down from 40 amps, with Wi-Fi and Bluetooth both and a holster in the box. It leads our best smart chargers roundup.
- EVDANCE 40A Portable - best portable set to 32A. A 40-amp portable whose current limit steps through 10, 16, 20, 24, 32 and 40 amps, so you can run it at 32 on a 40-amp outlet and take it with you. It also appears in our portable chargers roundup.
Why 32 amps, and when it is the right choice
32 amps earns its place for a specific, common situation: you want fast overnight charging but do not want - or cannot get - a bigger circuit. Two numbers explain why it works so well.
- It runs on a 40-amp circuit. EV charging is a continuous load, so the circuit is sized to 125 percent of the charger's current: 32 x 1.25 = 40. A 40-amp circuit on typically 8 AWG copper is a smaller, cheaper job than the 50-amp circuit a 40-amp charger needs or the 60-amp circuit a 48-amp charger demands - and far more panels can carry it without an upgrade.
- It matches a lot of cars.A great many EVs cap their onboard AC charger at 7.7 kW - which is exactly 32 amps. For those cars a 40- or 48-amp charger delivers no extra speed at all, because the car will not accept more. Check your car's onboard AC rate in the manual; if it is 7.7 kW, 32 amps is your real ceiling and paying for more buys nothing.
The practical takeaway: 32 amps is the answer when a panel upgrade is expensive or impossible, or when your car tops out at 7.7 kW. Buy an adjustable charger, set it to 32 amps to match a 40-amp circuit, and you lose almost nothing in real-world overnight speed. If your panel and car can both do more, the same adjustable units turn up to 40 or 48 - see our best 40-amp and best 48-amp rankings. Confirm the circuit with a licensed electrician.
Set it right: the app number and the breaker have to agree
An adjustable charger is only safe if the amperage you set never exceeds what the circuit behind it can carry. The rule is the continuous-load one in reverse: on a 40-amp breaker you set the charger to 32 amps (80 percent), on a 50-amp breaker to 40, on a 60-amp breaker to 48. Set it higher than the breaker allows and it will trip - or worse. On the ChargePoint, Emporia and Autel that number lives in the app; on the Grizzl-E Ultimate it is a physical setting inside the unit. Whichever it is, the person who sizes the circuit should set the amperage, and the two must match. Our amperage and breaker guide has the full table.
The picks, in order
Below the summary table each charger gets a full card with its score breakdown, pros and cons, and a "don't buy this if" note. In short: the ChargePoint wins on clean, app-set amperage and brand support, the Emporia on value and single-amp precision, the Grizzl-E Ultimate on a rugged hardwired build, the Autel on features, and the EVDANCE on being a portable you can dial to 32 and pack in the trunk. Every one genuinely runs at 32 amps; the choice is what you want wrapped around that setting.
How to choose a 32-amp charger
Because "32 amps" really means "an adjustable charger set to 32," the buying decision is a little different from a fixed-amperage roundup. Here is the order we used.
1. Confirm the circuit - and that 32 is your number
Settle two things first: that your panel can carry at least a 40-amp circuit, and what your car's onboard AC charger accepts. If the car tops out at 7.7 kW, 32 amps is your ceiling and the decision is easy. If the car accepts more but your panel can only spare a 40-amp circuit, 32 amps is still the right call - and an adjustable charger means you can turn it up later if you ever upgrade the panel. Our amperage guide walks the sizing.
2. How the amperage is set
This is the spec that matters most on a 32-amp page. The Emporia sets the current in single-amp steps in the app, which is the most precise; the ChargePoint offers clean fixed steps (16 / 24 / 32 / 40 / 48 / 50); the Autel adjusts in the app down from 40; and the Grizzl-E Ultimate uses a physical setting from 16 to 48. All hit 32 amps - pick the interface you would rather live with, and remember the setting has to match the breaker.
3. Build, and whether it plugs in or hardwires
A 32-amp install can be plug-in or hardwired. The EVDANCE portable and a plug-in ChargePoint or Emporia keep things movable; the Grizzl-E Ultimate is hardwired-only and built like a tank - cast aluminum, IP67 - which is the pick if it lives outside or you want the least to go wrong. Our best outdoor chargers ranking covers enclosure ratings if that is your situation.
4. Smart features and cable
Scheduling and energy monitoring pay off on a time-of-use electricity plan - the Emporia, ChargePoint and Autel all give you that, and it is the feature set that actually saves money by shifting charging to cheaper off-peak hours. The Grizzl-E is built around the hardware instead. On cable, longer is almost always safer; measure from the mount to your charge port and add slack.
So, which one?
Buy the ChargePoint Home Flex if you want clean, app-set amperage and one account for home and public charging. Buy the Emporia if you want the same 32 amps with single-amp precision and real monitoring for less - the value pick, and the right one for most. Buy the Grizzl-E Ultimate if it is going on a wall for good and you want the toughest box. Buy the Autel for the fullest feature set, and the EVDANCE if you want a portable you can set to 32 and take with you.
