High-capacity home backup with 3,200W output, 2,000W solar input, and a 30A RV outlet. Here's what we found.
3,200W LiFePO4 Home Backup & Solar Generator
The ALLPOWERS R3500 is a serious home-backup power station that competes directly with units twice its price. With 3,168Wh of LiFePO4 capacity, 3,200W continuous output, and a dedicated 30A RV plug, it handles everything from keeping your fridge and lights running during a blackout to powering a full RV setup off-grid.
The standout feature is the 2,000W solar input ceiling. Most competitors in this price range cap at 1,200W. That means you can fully recharge from solar panels in roughly 2.5 hours with the right panel array—a game-changer for extended outages or off-grid living.
The tradeoff? At 93 lbs, this is not a grab-and-go unit. It's a plant-it-and-use-it machine. If you need something portable for weekend camping, look at the lighter units in our reviews. But if you want deep capacity, fast solar charging, and LiFePO4 longevity at an aggressive price point, the R3500 delivers.

The 3,200W continuous output handles virtually any single household appliance. Full-size refrigerators, window AC units, microwave ovens, power tools — all within its operating range. The 6,000W surge rating gives it headroom for motor-driven appliances with high startup draws.
With 3,168Wh of capacity, here's what real-world runtime looks like:
This is where the R3500 separates itself. A 2,000W solar input ceiling is rare at this price point. Most competitors (EcoFlow Delta 2 Max, Jackery 2000 Plus) top out at 1,000-1,200W. More solar input means faster recharge, which matters most during multi-day outages when you're cycling the battery daily.
With a 2,000W panel array and good sun, you'll go from empty to full in about 2.5 hours. Even a modest 400W panel setup will refill it in roughly 8-10 hours of daylight — enough to cycle through overnight use and be ready again by the next evening.
The built-in 30A RV outlet is a genuine differentiator. Most power stations in this range require a clunky adapter to connect to an RV shore power inlet. The R3500 plugs straight in. For RV owners who boondock or dry camp, this eliminates an adapter, reduces connection points, and simplifies the setup.
LiFePO4 chemistry with 3,500+ rated cycles means this battery will outlast cheaper lithium-ion alternatives by a wide margin. At one full cycle per day, that's nearly 10 years before the battery degrades to 80% capacity. Even then, it doesn't stop working — it just holds less charge. This is a buy-it-once investment, not a unit you'll replace in 3-4 years.
Keep essentials running during multi-day outages. Sub-15ms UPS protects electronics instantly.
30A outlet plugs directly into RV shore power. No adapters, no hassle.
3,200W runs circular saws, drills, and compressors without a gas generator.
3,168Wh keeps your fridge cold and phones charged for 24-48 hours.
