RV and van life sit between camping and home backup. You're on the road for days or weeks at a time, with a daily load of 1-2 kWh (induction cooktop briefly + lights + fridge + phones), and your only recharge source is the rooftop solar array unless you're parked at a campsite hookup. The right unit is a 1-2 kWh LFP station with 200-400W of solar input headroom, ideally 12V DC out for direct integration with the camper's existing accessory circuits.
Solar input headroom is the spec most people miss. A 1500 Wh station with only 200W solar input takes 7+ hours of full sun to recharge from empty — fine in a Spanish summer, useless in Scottish autumn. A 1500 Wh station with 500W solar input refills in 3 hours, which actually fits within a single camp-stop day. The score below weighs solar input heavily and de-prioritises pure capacity.
12V DC out matters because it lets you power the camper's existing 12V loads (water pump, fans, LED strips) without inverter losses. Stations that only emit 12V via a cigarette-lighter port at 10A max are not suitable for high-draw 12V loads. Look for either Anderson Powerpole connectors or 12V output rated 25A+ — Bluetti AC180 and EcoFlow Delta 2 are the standouts here, the smaller River 3 lineup is borderline.
