Power station vs wired system
| Portable power station | Wired house battery | |
|---|---|---|
| Installation | None | Cables, fuses, mounting |
| Move it between vehicles | Yes | No |
| Charging while driving | Usually slow via 12 V socket, unless you add an alternator charger | DC-DC charger, fast |
| Expandability | Limited to the brand's extras | Almost unlimited |
| Best for | Weekends, rentals, stealth/minimal builds | Full-time living |
What to look for
- Chemistry: LFP (LiFePO4) for cycle life.
- Capacity (Wh): match to your daily need plus a reserve.
- AC output (W): enough for your biggest mains appliance.
- Charging inputs: solar input power, AC charging speed and alternator options.
- Pass-through charging and UPS behaviour if you work from the van.

EcoFlow DELTA 2
Best for: Part-time van users and renters who want power with zero permanent wiring.
- Capacity
- 1,024 Wh
- Chemistry
- LFP
- AC output

Specs: manufacturer page, checked 2026-11-14. Based on manufacturer specs and public reviews – not a hands-on test.
Other common van choices come from Bluetti, Jackery, Anker SOLIX and EcoFlow's larger DELTA models. We only publish specs we can trace to a manufacturer page.
When to graduate to a wired system
If you find yourself buying extra batteries, an alternator charger and roof solar for a power station, price out a wired LiFePO4 battery with a DC-DC charger – it often makes more sense at that point.
Frequently asked questions
Is a power station good for van life?
For weekend trips, rentals, leased vans or anyone who doesn't want to cut holes or run cables, yes. For full-time living with a fridge, heater and remote work, a wired system is usually more capable and easier to expand.
What capacity power station do I need for a van?
Estimate your daily watt-hours with our calculator. A compressor fridge alone can use a large share of a 1 kWh unit per day in warm weather, so many van users look at 1 kWh and above.
Can I charge a power station while driving?
Most can charge from a 12 V socket, but that's slow. Some brands sell dedicated alternator chargers that are much faster – check what's available for your model and market.
