| Battery capacity (Wh) | 512 Wh | How long it lasts. About 7 hours on a 60 W laptop. |
|---|---|---|
| AC output (W out) | 500 W | The most it can power at once. Keep your total below 500 W. |
| Solar input | Up to 220 W | How fast solar panels can refill it. Higher is quicker. |

| Wh per kg | 85 | Battery per kilo. Higher is lighter for the same capacity. |
Remember: the battery (Wh) sets how long it runs, and W out sets what it can run at the same time. You need enough of both. Check your own list in the power sizer.
