A 16 A portable charger is the simplest way to charge — but is it fast enough? Charging times for common battery sizes.
A 3.6 kW portable charger plugs into a suitable 16 A socket and needs no permanent installation. It is popular as a first charger, a travel backup, and for plug-in hybrids with smaller batteries.
| Battery | Approx. time at 3.6 kW |
|---|---|
| 20 kWh (typical plug-in hybrid) | ~5.5–6 h |
| 40 kWh | ~11 h |
| 60 kWh | ~17 h |
| 70 kWh | ~19–20 h |
| 82 kWh | ~23 h |
If you drive long distances daily or have a large battery, a 7 kW wallbox roughly doubles the speed. Either way, the socket must be on a dedicated, properly protected circuit — never an extension lead.
