S2 2500W Portable Power Station 2048Wh LiFePO4 UPS Backup 5500W Surge 1600W Fast Charge

S2 is a 2048Wh lithium iron phosphate power station built around one job: keeping a home alive while the grid is down. A 2500W pure sine wave inverter feeds four universal sockets at 110V, 120V, 220V or 240V, and the integrated UPS module transfers the connected load automatically when mains power disappears, so routers, medical equipment, security systems and work-from-home desks never reboot. The 460 x 270 x 313mm cabinet weighs 21kg, rolls into a hallway or utility room, and refills from a normal wall socket at up to 1600W.

Why households pick the S2

1. No reboot when the power drops. The UPS circuit senses the loss of mains power and switches the load over without interrupting sensitive electronics, which matters for desktop computers, NAS drives, routers and home medical devices.

2. 2048Wh of usable storage. A 51.2V, 40Ah LiFePO4 pack stores enough energy to run a 150W fridge for most of a day, or keep lights, WiFi and phones charged for several days of outages.

3. 2500W continuous, 5500W surge. Four universal AC outlets cover 110V to 240V appliances, and the surge rating absorbs the start-up current of compressors, pumps and kitchen equipment.

4. Refill fast, from sun or socket. 1600W AC charging brings the pack back quickly after an outage, while up to 2100W of PV input through the MPPT controller keeps it topped up during longer blackouts.

5. Visibility from your phone. The app and WiFi module report state of charge, input wattage and outlet status, so a household knows the reserve before the next storm arrives.

S2 is delivered with a colour box and export carton, a two year warranty and OEM logo support for distributors running their own brand of home backup power.

Factory and quality behind every S2

SOUOP has manufactured portable energy storage since 2008 from its base in Shenzhen, Guangdong. The plant runs its own BMS development, pack assembly and inverter lines, employs between 101 and 500 people, and ships 80 to 90 percent of output to Europe and North America. Every unit passes a full charge and discharge test, an aging cycle and a high voltage insulation check before it is packed.

Quality is audited rather than claimed. The factory holds ISO 9001 quality management, BSCI social compliance and CE, RoHS certification for the S2 series, with incoming cell sorting, in-process inspection and a traceable serial number on every battery pack. Distributors receive the test record for their production batch on request.

Because we control the pack, the inverter and the enclosure in one place, changes move quickly: different outlet standards, cabinet colours, logo printing and app branding can all be handled on OEM and ODM orders, with typical lead time of 7 to 15 working days after payment.
