650Wh 300W Compact Portable Power Station With 220V Pure Sine Wave AC Output

650Wh 300W Portable Power Station with 220V Pure Sine Wave AC Output

This compact portable power station combines a 650Wh LiFePO4 battery with a 300W pure sine wave inverter. It provides a convenient power source for compatible laptops, routers, lighting, communication devices and selected low-power AC equipment when a fixed socket is unavailable.

The metal enclosure measures 250 × 230 × 175mm and weighs 8.45kg net. Its relatively compact size supports movement between indoor backup points, temporary work areas, service locations and covered mobile applications.

A Compact Power Station Built Around Priority Devices

The 650Wh battery capacity and 300W inverter output represent two different selection factors. Battery energy influences possible operating time, while inverter output limits the combined AC power that can be supplied at one moment.

For practical use, begin with the equipment that must remain available. Routers, communication devices, LED lighting and laptop chargers usually create a different load profile from heating appliances, pumps or motor-driven equipment.

220V AC and Direct USB Charging

The AC output range is listed as 220–240V, with a rated output of 220Vac ±5Vac. Pure sine wave output provides a stable waveform for compatible equipment, but voltage, frequency and power requirements must still be checked.

The station also provides USB 2.0 charging and PD 20W Type-C fast charging. Compatible mobile electronics can therefore charge directly without occupying the AC outlet.

The supplied specification lists an output frequency of 60Hz ±0.5%. Equipment that specifically requires 50Hz should not be assumed compatible without confirmation.

AC and Solar Recharge Options

AC charging accepts an input range of 90–280V and is rated at 300W. A compatible utility or generator source may be used when its voltage and frequency remain within the documented limits.

The PV charging input supports 12–60V and up to 250W. Solar-panel open-circuit voltage must remain below the input maximum under the coldest expected conditions, not only during normal daytime operation.

Actual solar charging power varies with sunlight, panel temperature, shading, orientation and conversion losses. A 250W panel does not continuously deliver 250W throughout the day.

EPS Transfer and Placement

The station includes an EPS or UPS function with a listed transfer time below 50ms. Compatible devices may continue operating during a source change, but completely uninterrupted operation should not be promised for every connected product.

No water-protection rating is stated in the source specification. Keep the unit in a dry, ventilated and protected location away from rain, condensation, excessive heat and blocked airflow.

650Wh Portable Power Station FAQ

Can it run any appliance rated below 300W?

Not automatically. Startup demand, frequency, voltage and other connected devices must also be considered.

Is the output frequency 50Hz?

The supplied specification lists 60Hz ±0.5%. Frequency-sensitive equipment should be checked before ordering.

Can a solar panel connect directly to the station?

A compatible panel may be used when its complete voltage and power characteristics remain within the 12–60V and 250W limits.

Does the EPS function prevent every device from restarting?

No. The transfer time is listed below 50ms, but equipment response can vary.

What information is needed for device matching?

Provide operating wattage, startup demand, voltage, frequency and required operating time.
