Subaru Solterra Charging Time
A 2027 Subaru Solterra takes about 8 hours to charge from empty to full on a 240-volt Level 2 charger, according to its EPA test. On a standard 120-volt outlet it takes about 56 hours. A full charge puts about 80.4 kWh through the plug for 278 miles of range.
Subaru Solterra charging time by charger
Figures for the 2027 Solterra 20 AWD. 20% to 80% is a typical daily top-up; 0% to 100% is a full charge from empty.
| Charger | Power | 20% to 80% | 0% to 100% |
|---|---|---|---|
| Level 1, 120 V outlet (12 A) | 1.4 kW | 33 hr 30 min | 2.3 days |
| Level 2, 240 V, 16 A | 3.8 kW | 12 hr 34 min | 20 hr 56 min |
| Level 2, 240 V, 24 A | 5.8 kW | 8 hr 23 min | 13 hr 58 min |
| Level 2, 240 V, 32 A | 7.7 kW | 6 hr 17 min | 10 hr 28 min |
| Level 2, 240 V, 40 A | 9.6 kW | 5 hr 2 min | 8 hr 23 min |
| Level 2, 240 V, 48 A | 11.5 kW | 4 hr 11 min* | 6 hr 59 min* |
* Only if the car's onboard charger accepts that much power. On its EPA test it charged at about 10.1 kW; if that is its limit, a faster wall charger won't shorten the 8-hour full charge.

Cost to charge a Subaru Solterra
A full charge from empty draws about 80.4 kWh from the wall. At 18 cents per kWh it costs about $14.47, and a 20% to 80% top-up about $8.68. The EPA rates the Solterra 20 AWD at 28.9 kWh per 100 miles, which works out to 5.2 cents a mile. The US average home rate was 18.16 cents per kWh in August 2026 (EIA); the EV charging cost calculator takes your own rate.
Subaru Solterra fast charging
DC fast charging bypasses the car's onboard charger and is far quicker, but the speed depends on each model's charging curve, which slows as the battery fills. That's why fast-charge times are quoted from 10% to 80%. The EPA doesn't test DC charging, so check Subaru's quoted figure for the Solterra. The EV charging curve guide explains why it slows.
