Read this spec sheet from its step table outwards. Input: 240 V through a NEMA 14-50P plug. Current: six settable steps — 10, 12, 16, 20, 24 and 32 A. Output: up to about 7.7 kW through a NACS connector, with a 1.77-inch display and an IP66 enclosure rating as the sheet’s protection line. Every line is a check against your circuit and your car.
Key Takeaways
- Start from the step table: six steps, each paired with a breaker by the 125% rule, from 10 A on 15 A to 32 A on 40 A.
- The 14-50 plug names the receptacle shape, not the circuit behind it — read the breaker before choosing a step.
- About 7.7 kW is the ceiling at the top step; the car decides what it actually draws.
- IP66 is the sheet’s protection line and covers the enclosure only; the sheet lists no certification marks for this model.
Start With the Step Table
Most charger sheets give one current figure. This one gives six, and the steps are its most useful line, because EV charging is a continuous load: under the National Electrical Code the breaker is sized at 125% of the charging current. Each step therefore belongs on a specific circuit:
| Step you set | Breaker it belongs on (125% rule) | Power at 240 V |
|---|---|---|
| 10 A | 15 A | About 2.4 kW |
| 12 A | 15 A | About 2.9 kW |
| 16 A | 20 A | About 3.8 kW |
| 20 A | 25 A | About 4.8 kW |
| 24 A | 30 A | About 5.8 kW |
| 32 A | 40 A | About 7.7 kW |
A step is a ceiling you choose, not a promise the car will draw that much. Our guide to what size breaker an EV charger needs works through the same 125% rule in full.
Input Lines: 240 V and a 14-50 Plug
The input line pairs a voltage with a plug shape: 240 V, NEMA 14-50P. The plug names the receptacle the charger expects — the four-slot 240 V type described in our guide to what a NEMA 14-50 outlet is. What the plug does not tell you is the size of the circuit behind that receptacle: two identical-looking outlets can sit on different breakers. That is why the step table starts from the breaker, not from the socket.
Output Lines: About 7.7 kW and a NACS Connector
The headline output, about 7.7 kW, is arithmetic: the top step, 32 A, multiplied by the 240 V input. Set a lower step and the ceiling falls with it, as the table shows. That range sits inside the U.S. DOT’s Level 2 band of 7–19 kW. The last output line is the connector: NACS, so cars with a NACS inlet plug straight in. What the sheet cannot state is your session’s actual speed — the car’s onboard charger converts the power, and a car that accepts less than your step will draw less. The session runs at the lowest figure among step, circuit and car.
The Display Line and the Protection Line
The display line — a 1.77-inch screen — is the sheet’s feedback line: where you confirm the step you selected is the session the car is actually running. The protection line is a single rating: IP66, dust-tight and resistant to powerful water jets — our comparison of IP54, IP65 and IP66 ratings decodes the digits. IP66 describes this charger’s enclosure only, not your receptacle or your car. The sheet lists no certification marks for this model, so if a listing matters for a permit or an insurer, confirm it on the product page or with the manufacturer rather than assuming one.
The Charger Behind the Sheet
The EV-ACS3210T is the unit those lines describe: a 32 A NACS portable charger, about 7.7 kW, NEMA 14-50P, 10–32 A in six steps, IP66, made by EVDANCE (Shenzhen, founded 2011) with a three-year standard warranty. Our guide to reading an EV charger datasheet applies the same step-first method to any brand’s sheet.
Frequently Asked Questions
Is 7.7 kW the speed my car will charge at?
It is the ceiling, reached only at the 32 A step on a circuit that supports it. Your car draws what its onboard charger accepts, up to that ceiling — a car with a smaller onboard charger sets a lower pace on every step.
Which step should I use on a 40 A circuit?
The 32 A step: it is the setting the 125% continuous-load rule pairs with a 40 A breaker. Lower steps remain legitimate choices when the circuit is shared or the car is parked for a long stretch.
Does the IP66 line mean the charger can be left anywhere outdoors?
It means the enclosure is sealed against dust and powerful water jets. Placement still follows the manual, and the rating covers the charger itself — the outlet it plugs into needs its own protection from weather.
