Three EVDANCE portable chargers let you choose the charging current in steps: the EV-ACS3210T (six steps from 10 to 32 A), the EV-ACS4005T (four steps from 16 to 40 A) and the EV-ACS3210E (six steps from 10 to 32 A, including a 13 A step). The steps exist because the circuit in front of you is the real ceiling: you set the charger to what the supply can carry continuously, instead of asking the breaker to make that decision for you.
Key Takeaways
- Three EVDANCE portables set current in steps — and each model’s list is its own; never assume one model’s steps on another.
- Why adjust: the circuit is the ceiling, circuits get shared, unfamiliar supplies reward a low start, and cars accept less than chargers offer.
- The ACS3210E’s 13 A step and app monitoring, the ACS4005T’s 40 A top step, and the ACS3210T’s fine low end are the real differences.
- The EV-AC04001U is fixed-rate by design — the contrast that shows what adjustability is for.
The Three Step Sets, Side by Side
Each model’s step list is its own — they are close, but not interchangeable, and assuming one model’s steps on another is how a breaker gets tripped:
| Model | Connector and supply | Steps (A) | Top output |
|---|---|---|---|
| EV-ACS3210T | NACS portable, NEMA 14-50P (240 V) | 10, 12, 16, 20, 24, 32 | About 7.7 kW |
| EV-ACS4005T | NACS portable, NEMA 14-50P (240 V) | 16, 24, 32, 40 | 9.6 kW |
| EV-ACS3210E | Type 2 portable, single-phase (about 230 V) | 10, 13, 16, 20, 24, 32 | About 7 kW |
The differences are the selection logic. The 13 A step exists only on the ACS3210E. The ACS4005T starts at 16 A, and it is the only one of the three that reaches 40 A. The ACS3210T has the finest low end of the two NACS units, with 10 A and 12 A steps. How many amps a given job needs is covered in our guide to how many amps an EV charger needs.
Why Set Less Than the Maximum
- The circuit is the ceiling. EV charging is a continuous load, and under the NEC rule the breaker is sized at 125% of the charger’s current — so the setting must stay within what the circuit in front of you carries continuously. On a circuit you do not know, an electrician’s word outranks the charger’s top step.
- The circuit is shared. Other loads run for hours alongside the car; a lower step leaves them room.
- The supply is unfamiliar. Away from home, on a socket whose history you do not know, start low — you can step up once the setup proves itself.
- The car accepts less. Above the car’s own acceptance, a higher step buys nothing at all; the session runs at the car’s rate either way.
Beyond the Steps
The three are not distinguished by current alone. The ACS3210E adds an app with energy monitoring, and its listing describes it as OCPP-ready — that wording, exactly as listed. The two NACS units put the session on the unit itself: a screen on the ACS3210T, a display on the ACS4005T. The wider landscape is in our explainer on portable EV charger types.
The Fixed-Rate Contrast
One EVDANCE portable is deliberately not on the table above: the EV-AC04001U is not adjustable.
It is a fixed-rate 40 A (9.6 kW) J1772 portable, and a fixed unit gives you no way down when a supply cannot carry 40 A continuously. That gap — a real circuit, adequate overnight, but not a 40 A circuit — is what the step sets exist to close.
The Three Adjustable Models
The EV-ACS3210T is the low-step NACS portable: six settings to 32 A (about 7.7 kW), a screen, IP66, on a NEMA 14-50P plug. The EV-ACS4005T is the high-power portable: four settings to 40 A (9.6 kW), a display, a 25 or 28 ft cable, IP66. The EV-ACS3210E is the Type 2 portable for single-phase markets: six settings including 13 A, about 7 kW, a 7.5 m cable, app monitoring and OCPP-ready connectivity, IP66.
Frequently Asked Questions
Does a lower setting use less electricity?
No. The car takes about the same energy for the same driving; a lower step spreads that energy over more hours. What the setting changes is the load on the circuit, not the size of the bill for a full charge.
Can I dial any current I want between the steps?
No — only the listed steps on each model, and the lists differ: there is no 13 A on the NACS units and no setting below 16 A on the ACS4005T. Check the table against your circuit.
Which adjustable model fits a European home?
The EV-ACS3210E — it is the Type 2, single-phase unit. The other two are North American chargers with NACS connectors on NEMA 14-50 plugs, and their step lists are written for 240 V circuits.
