650Wh 300W Portable LiFePO4 Battery Power Station With Pure Sine Wave AC Output

650Wh 300W Portable Power Station with LiFePO4 and Pure Sine Wave AC Output

This compact portable power station combines a 650Wh LiFePO4 battery with a 300W pure sine wave inverter. It provides AC, USB and USB-C power for compatible electronics, communication devices, lighting and selected low-power equipment when fixed utility power is unavailable or inconvenient.

The metal housing measures 250 × 230 × 175mm and weighs 10kg net. Its compact dimensions make it easier to position in a protected work area, temporary service point, vehicle-supported project or indoor backup location without requiring a permanent wall or rack installation.

What the 650Wh and 300W Ratings Mean

The 650Wh value represents nominal stored battery energy, while 300W is the rated continuous AC output. These two values answer different questions: battery energy influences operating time, and inverter power limits how much compatible equipment can run at one time.

Before connecting a device, check its normal operating power and temporary startup demand. Equipment with heating elements, compressors, motors or high-power adapters may exceed the 300W rated output even when it operates only briefly.

AC, USB and USB-C Device Charging

The AC output uses a pure sine wave waveform with a rated voltage of 110Vac ±5Vac and a 60Hz frequency platform. Pure sine wave output provides a stable AC waveform for compatible equipment, but device voltage, frequency and power requirements must still match.

Two USB 2.0 charging ports support compatible USB-powered equipment, while the Type-C interface provides PD 20W fast charging. The charging demand of all connected devices should be included when evaluating the total output load.

Recharge from AC Power or Solar Input

The station supports AC and PV charging. AC input can come from a compatible utility or generator source within the specified voltage and frequency range, with a listed AC charging power of 300W.

Solar charging uses a 12–60V PV input range with up to 250W of charging power. The solar array or portable panel must remain within the voltage limit under all expected operating conditions.

Actual charging time depends on the available input power, battery state, operating temperature and conversion conditions. A solar panel’s nameplate rating does not guarantee the same power throughout the day.

Using the EPS Transfer Function Correctly

The specification lists an EPS or UPS transfer time of less than 50ms. This can support compatible equipment during a change in power source, but it should not be described as completely uninterrupted for every device.

Some sensitive equipment may restart or react to a short transfer. Compatibility should be tested with the actual device when continuous operation is important.

650Wh Portable Power Station FAQ

Can it operate a device rated exactly at 300W?

The device’s continuous and startup demand should both be checked. Operating with additional loads may exceed the rated output.

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 input limits.

Does pure sine wave mean every appliance is compatible?

No. Voltage, frequency, rated power and startup demand must still match the station.

Will the EPS function prevent every device from restarting?

Not necessarily. The listed transfer time is below 50ms, but individual equipment can respond differently.

What load information is needed before selection?

Provide each device’s operating power, startup power, quantity and required operating hours.
