ALLPOWERS R3500
A larger portable-backup battery with a different output limit in UPS mode. Check the operating mode as well as the headline wattage.
What changes the decision
The R3500 has 3,168 Wh nominal capacity and 3,200 W rated AC output on the current US listing. It is a larger energy-capacity alternative to the S2000 Pro, with LiFePO4 chemistry.
The manufacturer states a 1,500 W limit in UPS mode, which is lower than the headline inverter output. A transfer-time claim is not a guarantee that every computer, medical device or appliance will operate without interruption.
An expansion battery is optional and is not included in the standalone listing. The manufacturer currently shows its B3000 expansion battery sold out, so do not base an immediate purchase plan on expansion being available. Solar-panel and car-charging cables also need a package check.
Compare supported appliance loads, startup demand and actual runtime. Household wiring and transfer equipment are separate professional installation decisions.
