Detailed overview: Allpowers S300 Plus portable power station
The Allpowers S300 Plus is a compact portable power station that offers a lot for its size and price. With its 288 Wh LiFePO4 battery and a 300 W pure sine wave inverter (up to 600 W peak), it is designed for small and medium everyday portable devices: a smartphone, a tablet, a laptop, lighting, a router, a camera or small camping gear.
Its strength is how well-equipped it is for its size. It combines an AC outlet, a USB-C 100 W port (rare at this format, able to charge a laptop at full speed), two USB-A ports, a 12 V car output, a wireless charging pad on top and even a built-in LED light, handy for camping or during an outage. It is controlled through the ALLPOWERS app (Bluetooth), which lets you monitor charging and turn outputs on or off remotely.
For charging, expect about 1.5 hours for a full charge from the mains, 3 to 4 hours via solar (MPPT input up to 100 W) or from the car's cigarette-lighter socket. Its LiFePO4 battery ensures good longevity and greater safety than older lithium-ion cells.
Its limits are those of its format: 288 Wh and 300 W suit top-up use (charging devices, lighting, small gear), not running large appliances or a heater. But for anyone after a compact, light (3.4 kg), very well-equipped power station at a low price, the S300 Plus is one of the most attractive options in its category.

What is this power station best for?
-
Camping & Tent Ideal
At just 3.4 kg for 288 Wh, the S300 Plus is the ideal companion for the light-travelling camper: it easily handles lighting, charging phones, tablets and watches, a small fan, and even its built-in wireless charger and LED lamp, very handy in the tent. Its 300 W output (500 W peak) covers everyday small devices, and its slim format slips into a bag or a corner of the boot. Rechargeable in 90 minutes from mains and up to 100 W from solar, it lasts a modest camping weekend. For large cooking appliances, a more powerful station is preferable.
-
Remote work Suitable
For occasional work away from the office, the S300 Plus keeps the essentials running: its 300 W output powers a laptop and a router or 4G box for several hours, and its 60 W USB-C recharges a second device in parallel. Its 288 Wh suit a morning or a video meeting in a garden, a workshop or a shared space without an outlet. Very light (3.4 kg), it moves around effortlessly. Its modest capacity and 300 W output reserve it for light work: a dual-monitor setup or a printer will call for a beefier model.
-
Photo & Video Suitable
On a photo or video outing, the S300 Plus is a discreet backup station: its 288 Wh recharge several sets of mirrorless batteries, drone packs and lavalier mics, and its 300 W output runs a small LED panel or a fast charger between takes. Its wireless charger and 60 W USB-C simplify charging phones and audio gear. At 3.4 kg it fits in the camera bag and follows the photographer scouting or wandering, where a large station would be overkill.
-
Road trip & Car Suitable
Compact and rechargeable from the car socket while driving, the S300 Plus is a good road-trip companion: it keeps a small cooler cold at stops, recharges phones, cameras and a laptop, and doubles as a light in the evening thanks to its built-in lamp. Its 288 Wh and 3.4 kg fit anywhere in the cabin. For several successive nights off-grid, its modest capacity will need regular recharging, in the car or via a small solar panel.

Comparison
Under £171, the Allpowers S300 Plus compares with the most sought-after small 250 to 300 Wh power stations, through searches such as "S300 Plus vs EcoFlow River 2" or "S300 Plus vs Jackery 300". Here is how it stacks up against three of its most compared alternatives: the EcoFlow River 2, the fastest to recharge, the Jackery Explorer 300 Plus, a segment benchmark, and the Bluetti EB3A, more powerful.
| Criterion | Allpowers S300 Plus | EcoFlow River 2 | Jackery Explorer 300 Plus | Bluetti EB3A |
|---|---|---|---|---|
| Capacity | 288 Wh | 256 Wh | 288 Wh | 268 Wh |
| Continuous / peak power | 300 W / 600 W | 300 W / 600 W | 300 W / 600 W | 600 W / 1200 W |
| Battery chemistry | LFP (LiFePO4) | LFP (LiFePO4) | LFP (LiFePO4) | LFP (LiFePO4) |
| Mains recharge 0-100% | ≈ 1 h 30 | ≈ 1 h | ≈ 2 h | ≈ 1 h 10 |
| Weight | 3.4 kg | ≈ 3.5 kg | ≈ 3.75 kg | ≈ 4.6 kg |
| Observed price | ≈ £162 | ≈ £170 | ≈ £256 | ≈ £221 |
In short, the Allpowers S300 Plus is the most compelling option on budget and equipment: it is the cheapest of the group, one of the lightest, and the best equipped for its format (USB-C 100 W, wireless charger, LED light and app control). The EcoFlow River 2 recharges faster (1 h) and benefits from a very established brand, while the Bluetti EB3A wins on power (600 W). For top-up portable use on small and medium devices, at the best price, the S300 Plus is hard to beat.

Our tester's review: Christophe Delpuech
We tested the S300 Plus for several weeks, and for a station this size it is surprisingly complete. Compact as a small shoebox and light (3.4 kg), it fits anywhere. What stands out first is the USB-C 100 W port: rare at this format, it charges a laptop at full speed, where many rivals cap at 60 W. The wireless charging pad on top and the built-in LED light are two well-thought-out extras for camping or an outage. We also liked the Bluetooth app, which lets you monitor charging and switch ports off remotely, not that common on such an affordable model. Its 288 Wh and 300 W suit small and medium devices (phones, laptops, lighting, a router, small gear), not running large appliances. Two honest downsides: the 300 W output limits its uses, and a few users report a perfectible finish on the fans. But at under £170, with this level of equipment, it offers formidable value for a first portable station.
