ZeroKor Portable Power Station 300W, 280Wh (without Solar Panel)

- 280Wh, 300W max, ~5 lbs
- MPPT-enabled, 3 recharge paths
- 12-month customer support
Our take
Three charging methods (home AC outlet, DC5521 13V-23V solar panels sold separately, or 12V car charging cable) work with a built-in MPPT controller, and the listing specifically warns that devices over 300W, especially heat-prone appliances, can damage the unit.
Why it made the shortlist
This 280Wh station delivers 300W max output (AC outlet) through multiple charging ports: dual AC outlets, a DC port, three 5V/3A USB ports, and a QC USB port, with an LED flashlight offering reading and SOS modes. At about 5 lbs with a handle, it's genuinely easy to fit in a car for indoor or outdoor use.
Built-in BMS covers short-circuit, over-current, over-voltage, and overload protection, with a 12-month customer support commitment and a specific recommendation to recharge at least every half-month if idle.
What works
- Built-in MPPT controller optimizes solar charging when a panel is added
- About 5 lbs makes this genuinely easy to fit in a car trunk
- SOS-mode flashlight adds real emergency utility
Watch out for
- No solar panel included, must be purchased separately
