DYNESS PPS2400

DYNESS is better known for home and commercial battery systems than for portable stations, and the PPS2400 brings that LiFePO4 experience to a 2kWh portable at a very low price. You get 2,048Wh of capacity rated for 4,000+ cycles, a 2,400W pure sine wave inverter and six AC outlets, enough to run a refrigerator for roughly 12–18 hours or cover a home office through a long outage.

Outputs are generous: six AC outlets, four USB-C (one at 100W, three at 20W), two 12V DC ports and a 12V car port. There's a built-in LED light, a handy storage compartment on top and app control. DYNESS also says it can recharge from a 12–36V LiFePO4 battery through its 12V input, which is useful in vans and RVs.

Charging is where it saves money. AC input is 1,100W, so a full charge takes about 2.3 hours (0–80% in about 1.8), and solar tops out at 500W through an MPPT input. Use both together and DYNESS quotes 0–80% in about 1.2 hours. That's fine for overnight top-ups but slower than EcoFlow's or DJI's 1,800W wall charging.

Some specs are less clear than we'd like. DYNESS's US Amazon listing claims a 4,800W surge while its own EU spec sheet lists 3,000W peak, and the spec sheet doesn't give a UPS switchover time. At 48.5 lb it's heavy for its capacity. If the price is the priority and you can live with slower charging, it's a lot of LiFePO4 for the money.
