SEVR EV Portable Charger (10A)
Plugs into any standard power point. About 129 km per 10-hour night, and it travels in the boot.
Most BMW i4 charging happens at home, overnight. Here are the real numbers for a standard power point and a dedicated 15 A outlet, for every battery size.
The BMW i4 has a Type 2 inlet, so any Type 2 portable charger fits. On a standard 10 A power point, a 10-hour night adds about 129 km (about 29% of a 70.2 kWh battery); on a dedicated 15 A outlet, about 194 km. A 20→80% top-up of the BMW i4 eDrive35 takes about 20.3 hours on 10 A or 13.6 hours on 15 A.
20→80% is the everyday top-up. 10→100% is the worst case: arriving home nearly empty and filling to the top.
| Variant | Battery (approx.) | 20→80% on 10A | 20→80% on 15A | 20→80% on 7 kW | 10→100% on 10A | Nights on 10A, 10→100% |
|---|---|---|---|---|---|---|
| BMW i4 eDrive35 | 70.2 kWh | 20.3 h | 13.6 h | 6.3 h | 30.5 h | 4 |
| BMW i4 eDrive40 / M50 | 83.9 kWh | 24.3 h | 16.2 h | 7.6 h | 36.5 h | 4 |
| Variant | Battery | 20→80% at 28c | 10→100% at 28c | 10→100% at 18c | 10→100% at 10c |
|---|---|---|---|---|---|
| BMW i4 eDrive35 | 70.2 kWh | $13.10 | $19.66 | $12.64 | $7.02 |

Yes. The BMW i4 uses the Type 2 AC inlet, like every EV sold new in Australia today, so any Type 2 portable charger fits.
About 20.3 hours from 20% to 80%, or 30.5 hours from 10% to 100% (about 70.2 kWh battery). Each hour adds about 13 km of range.
About 16.2 hours from 20% to 80% on a dedicated 15 A outlet (about 83.9 kWh battery). A 10-hour night adds roughly 194 km.
About $13.10 for a 20→80% top-up of the BMW i4 eDrive35 at 28c/kWh, or $4.68 on a 10c/kWh overnight EV plan, including about 10% charging losses.
Not if you drive under about 150 km a day. A 15 A portable charger adds about 194 km overnight, and a 10 A one about 129 km. A 7 kW wall charger suits long daily drives or two EVs. See portable vs wall charger.
No. Powerboards and extension leads aren't built for hours of continuous load. Plug the charger straight into the wall, and stop if the plug or outlet feels hot.
