Aferiy P310 Review: A 3600W Power Station Priced Like a Mid-Range Unit

Introduction

Large-capacity portable power stations have historically come with large-capacity price tags. Comparable boxes in the 3,600W class from other brands typically sell around $3,500, and even during aggressive sales they tend to hover closer to $2,500. The Aferiy P310, on sale for $1,099 as a limited-time Halloween deal, disrupts that expectation entirely.

If you have been waiting to buy a power station, this is arguably the one to look at. Let’s go through what it offers, how it performed under load, and who it makes sense for.

What the P310 Actually Offers

Aferiy’s earlier 2K-class box was well received, and the P310 is a clear step up. It is a 3,600W power station with a 3,840Wh battery capacity, and the port selection is genuinely extensive:

• Four 120V AC outlets plus a 30-amp RV outlet
• Two 12V outputs (10-amp and 25-amp) and two 12V 3-amp barrel plugs
• Two QC 3.0 USB-A ports
• Four USB-C ports: three at 20W and one at 100W
• An XT60 input for solar charging
• Support for an expandable battery with USB output, also rated at 3,600W

Both the main unit and the expansion battery share a luggage-style handle, which matters because these are heavy units. Aferiy does not shy away from the weight here; this is a serious piece of hardware, not a lightweight grab-and-go box.

Real-World Performance

Under load, the P310 is in a different class from 1K or 2K boxes. Running a DeWalt tool and a space heater set to high simultaneously barely registered. The heater, which has killed other power stations in past testing, ran without the capacity draining meaningfully, and that was on the main unit alone with the expansion battery switched off.

This is whole-home kind of power. In an ongoing studio setup, the P310 now runs an entire print farm: eight 3D printers can all fire up at the same time without tripping a breaker, in a building that is notoriously twitchy about electrical load.

One honest caveat: these are not the quietest boxes. You can definitely hear it running. It is not a turbojet fan by any means, but it is audible during operation.

Expandability and Charging

The back of the unit is well laid out. There is a stopper on the rear so the unit can be stood upright on its end while carrying, plus ports for extra batteries, battery charging, and solar input. It even has a built-in light.

Charging flexibility is strong: solar, wall charging, or both at the same time. Combined with the expansion battery port, the system scales well beyond the 3,840Wh base capacity if your needs grow.

Why This Price Stands Out

This style of box from competing brands runs about $3,500, and even at their best sales those units come in around $2,500. The P310 sits at $1,099. The speculation is that Aferiy is clearing stock ahead of a new model, but whatever the reason, the value is difficult to argue with.

The full package includes LiFePO4 battery chemistry, a smart BMS, a companion smart app, comprehensive input and output protection, and the expandability already covered above. Finding all of that in a system of this size at anywhere near this price is genuinely hard to do.

Buying Advice

The P310 makes sense if you want serious backup or off-grid capacity without paying the traditional 3K-class premium. It suits homeowners who want whole-home-style coverage, RV owners thanks to the 30-amp outlet, workshop users running multiple devices, and anyone building an expandable solar setup.

If portability is your top priority and you only need to charge phones and laptops, a smaller and lighter box is the better choice. But if capacity, output, and expandability matter most, this is an easy recommendation at this price.

Conclusion

The Aferiy P310 combines 3,600W of output, a 3,840Wh expandable LiFePO4 battery, an unusually rich port selection, and a sale price of $1,099 that undercuts comparable systems by thousands of dollars. Add in the audible fan as the only real drawback, and this is arguably the power station deal of the year. If a new model is coming, this clearance price is the time to buy.
