The camper van battery bank should last 3-4 days without charging but entirely depends on actual usage
Typically you can expect the battery bank to last 3-4 days without charging if only using outlets for devices, lighting, and ceiling fan. However, as long as the van roof has sunshine access and the van engine is running idle or while on the road, the lithium battery bank will be charging automatically. These travel vans have self sustaining systems that make it unlikely you will run into power issues.
If you're using the hot water heater, stovetop, electric kettle, and anything else that gets hot, you can expect to run out of power in a much shorter amount of time.
Pro Tips:
- Try to camp in locations that have a clear view of the sky. This will maximize your solar charging time and prevent power from ever becoming an issue.
- If you're staying at a campground with shore power hook-ups, use them! Plugging in to shore power will charge the electrical system AND any electrical usage during that time will come from your power source giving you unlimited power (for the time being).
- In the event you only have access to a standard 110v outlet, you can find a charging adaptor in the storage nook under the bed.
- The van engine will charge your solar electrical system whenever it is running. This means, while you're on the road driving, it's charging. While you're parked with the engine idling, its charging. We don't recommend keeping your engine running while park (save the trees!) but if you find yourself in a tough situation, it's an effective last resort.
