Choose the setting by what feeds the charger, not by what the car can take. On the EV-ACS3210E, the 10 A and 13 A steps are for ordinary household sockets, 16 A to 24 A suit commando sockets and stronger household circuits, and 32 A belongs only where the circuit was built for it. The supply, not the car, sets your ceiling.
Key Takeaways
- Six settings, three supply classes: 10/13 A for sockets, 16–24 A for commando sockets and stronger circuits, 32 A for a dedicated circuit.
- The supply sets the ceiling; the car takes what it is offered. Start low whenever the circuit is unknown.
- The 13 A step exists for socket-limited homes — about 30 kWh across a ten-hour night, before losses.
- App monitoring shows what a session really delivered — how you learn your home’s honest step.
The Six Settings at a Glance
Power below is plain arithmetic at 230 V:
| Setting | Power at 230 V | The job it fits |
|---|---|---|
| 10 A | About 2.3 kW | An ordinary household socket; visiting, emergencies, gentle top-ups |
| 13 A | About 3.0 kW | The top of the socket class — socket-limited charging that finishes overnight |
| 16 A | About 3.7 kW | A commando socket or a household circuit with real headroom |
| 20 A | About 4.6 kW | The middle step, for stronger circuits not built for 32 A |
| 24 A | About 5.5 kW | A near-full session on a substantial circuit |
| 32 A | About 7.4 kW | The unit’s ceiling — a dedicated circuit built for continuous charging |
Read the table as a ladder of supplies, not a ladder of ambition. Every step is a legitimate way to charge; the only wrong choice is a step the supply cannot carry for hours.
Start From the Supply, Not the Car
EV charging is a continuous load — one level, for hours. Three habits keep the choice simple:
- Identify what you are plugged into first. A household socket, a commando socket and a dedicated circuit are three different ceilings. If you do not know which you have — a rental, a holiday home — start at the lowest step and treat anything more as an electrician’s question.
- Leave headroom below the ceiling. A supply run at its face rating for hours has nothing in reserve; the step below is the working choice.
- Do not chase the car’s maximum. The car’s onboard charger accepts what it is offered, up to its own limit. A lower setting costs time, not energy — the battery takes roughly the same total either way.
The unit carries a Type 2 connector for Type 2 markets, as our comparison of Type 2, J1772 and NACS explains.
Why a 13 A Step Exists
Most adjustable chargers jump from 10 A to 16 A. The 13 A step fills the gap socket charging actually lives in: homes where 10 A is slower than the night allows, but the supply is still an ordinary socket — an older house, a shared household circuit, a guest stay. At about 3.0 kW it adds roughly 30 kWh across a ten-hour night before losses, against about 23 kWh at 10 A — often the difference between “topped up” and “ready for the trip home”. It is still socket-class charging, not a substitute for a proper circuit if you charge every day.
Setting It, and Seeing What It Did
The current is set in the unit’s app, and the app’s energy monitoring shows what each session delivered — the quickest way to learn which step your home supports, because a setting the supply cannot hold shows up as interrupted sessions, not faster ones. The unit is also OCPP-ready, for owners who later want managed sessions; our explainer on what OCPP means for charger hardware covers that layer. The EV-ACS3210E is a single-phase Type 2 portable of about 7 kW with a 7.5 m cable and IP66 sealing.
Frequently Asked Questions
Which setting should I use overnight at home?
The highest step your supply honestly supports — and if your charging point is a household socket, that is the 10 A or 13 A step, not 32 A. Even 10 A adds about 23 kWh across ten hours before losses, covering most drivers’ daily use.
Does a lower setting waste electricity or harm the battery?
No. The battery takes roughly the same total energy either way; a lower setting spreads it over more hours. The setting only decides how much the supply is asked for.
Can I use the 32 A setting on a normal household socket?
No. A household socket is socket-class supply; 32 A needs a circuit installed for continuous charging. If you want the top step at home, have a qualified electrician assess the supply and install the appropriate circuit.
