Why RV appliances behave differently

Many RV appliances, like fridges, vent fans, and lights, run on modest wattage and cycle on/off. But larger appliances like microwaves or electric kettles demand a lot of power in short bursts. Even though those bursts may only last a few minutes, they require a power station that can handle high surge watts. 

Practical note: A refrigerator typically runs 100 to 150 watt-hours per hour of actual compressor runtime, cycling on about 40% of the time. A 1000Wh power station can run a typical RV refrigerator for roughly 24 hours. Air conditioning uses 1200 to 1500 watts while running. Even a large power station provides only a few hours of AC, so most boondockers use AC sparingly or not at all unless they have a very large system or generator backup.

Recommended bundles: Three Levels of Setup

Level 1: Weekend Trips and Light Use

For overnight stops, short camping trips, and charging devices while keeping lights and fans running. Handles phones, laptops, cameras, LED lights, and small 12V accessories. Not intended for running a refrigerator overnight or powering AC appliances continuously.

Power stations: EcoFlow RIVER 3 (245Wh) or RIVER 3 Plus (286Wh, expandable to 858Wh). Compact and portable enough to move between your vehicle and campsite.

Solar panels: EcoFlow 110W Portable Panel or RICH SOLAR 100W Portable Briefcase for ground deployment at camp.

Level 2: Extended Weekends and Moderate Use

For 2- to 4-day trips running a 12V refrigerator, charging multiple devices, using small AC appliances like a coffee maker or blender, and occasionally powering a laptop workstation. This is the practical minimum for comfortable boondocking with a refrigerator.

Power stations: EcoFlow DELTA 3 (1024Wh) or DELTA 3 Plus (1024Wh, expandable to 5kWh). These provide enough capacity to run a refrigerator overnight plus typical daily use, with output to handle most small appliances.

Solar panels: 200W or more recommended. RICH SOLAR MEGA 200 for roof mounting, or EcoFlow 220W Bifacial Portable Panel for flexible ground deployment. With 200W of solar and good sun, you can approach energy-neutral camping and extend your trips indefinitely.

Level 3: Full-Time and High-Demand Use

For full-time RVers, extended off-grid stays, or anyone who wants to run AC appliances without worry. Supports residential refrigerators,

microwaves, induction cooktops, hair dryers, and short periods of air conditioning. With expansion batteries, these systems can approach whole-RV power independence.

Power stations: EcoFlow DELTA Pro (3600Wh, expandable to 25kWh) or DELTA Pro 3 (4096Wh). Both include a TT-30 RV outlet to plug your camper in directly. The DELTA Pro 3 adds faster charging, higher efficiency, and IP65 dust/water resistance.

Solar panels: 400W or more recommended. Multiple RICH SOLAR MEGA 200 or MEGA 250 panels for permanent roof installation, or EcoFlow 400W Portable Panel for high-output portable use. With 400W+ of solar, you can recover significant capacity during daylight hours even while running loads.

Expansion: Add an Extra Battery to double your capacity. The DELTA Pro supports up to 25kWh of total storage with multiple batteries.
