Best portable charger for BYD Sealion 7 and Atto 3

The Sealion 7's bigger battery takes longer to fill than the Atto 3's, but overnight top-ups work the same way. Here are the numbers for both, plus the Atto 2.

The short answer

The BYD Sealion 7 uses the Type 2 inlet, so any Type 2 portable charger fits. On a dedicated 15 A outlet a BYD Sealion 7 (about 82.5 kWh) goes from 20% to 80% in about 15.9 hours; on a standard 10 A power point it takes about 23.9 hours. Most owners top up overnight instead.

  • Charging at home: EVSE Australia 15A portable charger, about 194 km over a 10-hour night.
  • No outlet install possible: SEVR 10A portable charger, about 129 km per night.
  • Home plus travel: both chargers, 15A at home and 10A in the boot ($399 as the Home + Travel bundle).
  • Fit: Type 2 inlet. Check your car before ordering; the owner's manual lists the inlet type.
