RV, Van Life & Marine Power

Add up your daily use. Lights, fans, a water pump and a 12V fridge typically use 1–⁠2 kWh a day, and a microwave, coffee maker or TV adds more. A 200–⁠300Ah 12V lithium bank (about 2.5–⁠4 kWh) covers most weekends without hookups.

Yes, with enough battery and a large enough inverter. A typical 13,500 BTU RV AC draws about 1,200–⁠1,500 watts while running, so 5 kWh of battery runs it for roughly 3–⁠4 hours. A soft starter helps the AC start on battery power.

Yes. An alternator or DC‑to‑DC charger, like the BLUETTI Charger 2 or EcoFlow Alternator Charger, charges your batteries or power station from the engine while you drive.

A power station is an all‑in‑one battery and inverter you plug into. A built‑in system wires lithium batteries, an inverter charger and solar into your rig. Compare them in the table above.

Many do, for electronics, lights and small appliances. Keep it dry and secured, since most power stations aren't waterproof. For permanent systems, use batteries rated for marine use and have them installed to marine wiring standards.

Not always. In sunny weather, 400W or more of solar can keep up with lights, a fridge and devices. A generator helps with rooftop AC, cloudy stretches and other big loads.
