Laptop hours on the DELTA 2 Max
| Case | Watts | On the DELTA 2 Max |
|---|---|---|
| Laptop (Virginia Tech) | 50 W | 34.8 h |

Wh × 0.85 ÷ (watts + the station’s own draw, where the maker lists it).
Charging from the station’s USB‑C port skips the inverter, so it runs longer than these AC figures, if the port’s watts cover your charger.
Keeping it going with solar
An 8-hour workday with a laptop uses about 400 Wh, about 471 Wh from the battery. At the DELTA 2 Max’s 1,000 W solar input and our 75% assumption, that takes about 0.6 hours of strong sun to put back; a full charge from empty takes about 2.7 hours. See solar recharge time.
