ALLPOWERS VOLIX P300: 256 Wh Portable Power Station Overview

The ALLPOWERS VOLIX P300 is a portable power station with a 256 Wh LiFePO4 battery and an AC socket rated for 300 W of continuous output. It also offers USB and 12 V outputs, solar charging and a UPS function. It is mainly suited to powering smaller electronics while travelling, working outdoors or during a power outage.

Battery capacity and runtime

The 256 Wh battery uses LiFePO4 technology and is rated for more than 4,000 charge cycles. The station can recharge phones or laptops multiple times, or power less demanding devices for several hours. The number of charges depends on the devices’ battery capacities and energy losses during charging.

Not all of the 256 Wh capacity is available at the output: some energy is used to convert voltage and operate the station itself. At a constant 30 W load, the theoretical maximum runtime is approximately 8 hours and 32 minutes. Actual runtime will be shorter because of losses.

Outputs and power

The station has one Schuko AC socket rated at 300 W continuously, with a short-term peak of 600 W. It can power devices such as a laptop, charger or light, provided their power requirements are within the station’s limits. The peak rating does not mean it can run a 600 W appliance continuously. Schuko plugs are common in parts of Europe but are not standard in every English-speaking market, so check plug compatibility before use.

Other outputs include:

• USB-C with Power Delivery: 100 W is listed, but the port is marked 140 W on the device. This discrepancy makes the port’s maximum output uncertain.
• Two USB-A ports: rated at 18 W for charging phones, tablets and other small electronics.
• 12 V car socket: a 12 V/10 A output for compatible automotive accessories and other 12 V devices.

Several devices can be powered at once, but individual output limits and the overall load must be respected. The exact combined output limit is not specified here.

UPS, noise and portability

The UPS function can switch to battery power during a mains outage, with a stated transfer time of up to 10 ms. That transfer may not be seamless for every sensitive device, so check compatibility before relying on the station as a backup power source.

Noise is stated as 30 dB, which is useful for indoor use or camping. The station measures 260 × 210 × 125 mm and weighs 4 kg, making it portable enough to take on trips or to a worksite in the field.

Mains and solar charging

Mains charging is stated at 300 W, with the battery reaching 80% in approximately 40 minutes. The station also has a built-in MPPT controller and supports solar charging at up to 110 W.

Solar charging is stated to take approximately three hours. The actual time depends on available sunlight, panel output and other conditions. Before connecting a panel, check that it is compatible with the station’s input; the permitted voltage range and other input parameters are not specified here.

The VOLIX P300 combines AC, USB and 12 V outputs in a portable unit. Its 256 Wh capacity and 300 W continuous AC output make it better suited to smaller electronics than to running power-hungry appliances for long periods.
