12 V fridge hours on the R1500
| Case | Watts | On the R1500 |
|---|---|---|
| Dometic CFX3 35 on a hot day (Dometic) | 12 W | 3.4 days |
Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
Dometic lists 0.98 Ah per hour at 12 V with a 90°F room. These hours use our AC math; on the 12 V outlet the fridge skips the inverter, so it can run longer.
Keeping it going with solar
A day with a Dometic CFX3 35 on a hot day uses about 288 Wh, about 339 Wh from the battery. At the R1500’s 650 W solar input and our 75% assumption, that takes about 0.7 hours of strong sun to put back; a full charge from empty takes about 2.4 hours. See solar recharge time.
