Calculating Your RV’s Appliance Power Needs
Before you even look at a single product, you have to do your homework. Buying a power station without knowing your energy needs is like buying hiking boots without knowing your shoe size—you’re guaranteed a bad time. The most common mistake I see is underestimating consumption, leaving people with a dead battery just when they need it most.
Start by making a list of every appliance you want to run. Find the label on each one and look for its power draw in watts (W). If it only lists amps (A) and volts (V), a quick calculation (Watts = Volts x Amps) will get you there. Pay close attention to two numbers: running watts (the continuous power it needs) and surge watts (the initial burst of power needed to start motors, like in a fridge or AC unit).
Now, estimate how many hours per day you’ll use each item. A coffee maker might use 1000W, but only for 10 minutes (0.17 hours), so its daily consumption is about 170 watt-hours (Wh). Your fridge, however, might only draw 150W, but its compressor could run for 8 hours a day, totaling 1200Wh. Add up the watt-hours for everything essential. This final number is your target capacity, and you should always add a 20% buffer for safety.
EcoFlow Delta Pro for Whole-RV Backup Power
The EcoFlow DELTA Pro provides 3600Wh of power for home backup, camping, and emergencies. Charge quickly via wall outlets or solar, and expand capacity up to 25kWh with extra batteries.
When your goal is to replicate the shore power experience without being plugged in, the EcoFlow Delta Pro is the undisputed heavyweight champion. This isn’t just for charging phones; this is a serious energy hub designed to power an entire RV. With a base capacity of 3,600 watt-hours and a massive 3,600W continuous output (7,200W surge), it can handle demanding loads like a 13,500 BTU air conditioner, a microwave, and a water heater simultaneously.
The real magic of the Delta Pro is its expandability. You can chain together extra batteries to create a colossal energy bank of over 25,000Wh. It also integrates directly into your RV’s electrical system with a smart home panel, allowing for seamless, automatic backup the moment shore power cuts out. It’s a complete system, not just a box.
Of course, this power comes with tradeoffs. The Delta Pro is big, heavy (nearly 100 lbs), and represents a significant financial investment. It’s complete overkill for a small van or a weekend camper. But for full-timers who refuse to compromise on comfort and want a robust, all-in-one solution for total energy independence, there is simply nothing else on the market that competes at this level.
Bluetti AC200MAX: Expandable Energy Solution

Key Features to Compare in RV Power Stations
Choosing the right power station comes down to matching its capabilities to your specific needs. Don’t get lost in marketing hype; focus on the numbers and features that actually matter for life on the road. When you compare models, here are the non-negotiable factors to consider.
- Capacity (Watt-hours or Wh): This is your fuel tank. A 2000Wh battery can deliver 200 watts for 10 hours. Base this on the power audit you did earlier, and always err on the side of more capacity than you think you need.
- Output (Watts or W): This is your engine’s horsepower. The continuous output rating tells you the maximum wattage it can sustain, while the surge output is what it can handle for a few seconds to start motors. Your power station’s surge rating must be higher than the highest surge appliance you own (likely a fridge or AC).
- Battery Chemistry: The two main types are Lithium Iron Phosphate (LiFePO4) and Lithium-ion (NMC). LiFePO4 is the superior choice for RVs, offering 3-5 times more charge cycles (longevity) and a safer chemical structure. It’s often heavier, but the durability is worth it for a system you’ll use daily.
- Ports & Plugs: Look for a unit that has the connections you use most. Multiple USB-C PD ports are essential for modern electronics. For RV-specific use, a built-in 30-amp TT-30 outlet is a game-changing feature that lets you plug your rig in directly, no adapters needed.
- Weight & Portability: There is a direct and unavoidable tradeoff between power and weight. A massive 4000Wh station is great until you have to lift its 100+ pound bulk. Be realistic about how often you’ll need to move it and choose a size you can comfortably handle.
Ultimately, the "best" battery backup is the one that disappears into your routine, quietly and reliably doing its job. The right unit empowers you to travel further and stay longer, turning the dream of off-grid freedom into a comfortable reality. Start by understanding your own power habits, and you’ll find the perfect match to keep the lights on, wherever the road takes you.
