ALLPOWERS VOLIX P300 Portable Power Station, 256Wh 300W

- 256Wh, 300W (600W surge), 7.87 lbs
- 2hr 0-100% AC fast charge
- 6-year warranty, 4000+ cycles
Our take
Five devices connect at once across a pure sine wave AC outlet, 100W USB-C PD, dual USB-A fast charging, and a 12V car socket.
Why it made the shortlist
300W pure sine wave AC output (600W surge) from a 256Wh LiFePO4 battery covers laptops, CPAP machines, mini refrigerators, and drones without noise, fumes, or fuel. A genuine 2-hour 0-100% AC fast charge pairs with up to 110W MPPT solar charging and car charging support for flexible recharging on the road.
What works
- 6-year warranty is genuinely long for this compact capacity class
- 2-hour full charge is genuinely fast for a 300W-class station
- Under-20ms UPS specifically protects NAS systems, not just basics
Watch out for
- 300W output limits higher-draw appliance use
- 110W solar input is modest next to higher-wattage rivals
