Start with what needs power, how long it runs and how far you have to carry the battery.
Camping and campervans
Plan the energy between charging stops and include panels in the carrying load.
Mobile work and events
Budget the full session, the highest simultaneous load and a late finish.
Standalone home backup
Choose essential plug-in loads and keep household preparation separate from a battery purchase.

A quick way to choose a route
| Your situation | Start with | Then check |
|---|---|---|
| Carry it to a campsite | Energy until the next recharge | Station, panel and cable weight together |
| Finish a work session | All equipment and the full booking length | Simultaneous watts and a delayed finish |
| Keep essentials running at home | A short, explicit list of plug-in loads | Low-load settings, restart behaviour and a longer-outage fallback |
Each use guide combines a worked energy budget with our model recommendations.
