300W-500W UPS Power Station Series — Pure Sine Wave, ≤5ms Switchover
The Ruihan 300W-500W UPS power station series keeps small businesses and field work running through outages: POS terminals, ticket kiosks, routers, coolers and charging stations. Pure sine wave AC (220V 50Hz / 110V 60Hz with CN/US/EU plug options) switches over in ≤5ms when the grid drops, while DC 12V and four USB ports cover the rest.
Seven grades share one compact yellow/black ABS shell: four 300W units (18, 26, 31, 40Ah) and three 500W units (26, 31, 40Ah — 288, 345, 445Wh). All run ternary-lithium cells rated for about 1000 cycles from -20°C to 45°C, with a digital battery-capacity display and CE, FCC and RoHS markings on the shell.
Recharge from mains, solar or a car socket in 2.5 to 4 hours, and pack five units per export carton (52 x 36 x 42cm). One shell, seven SKUs — a lean line for distributors targeting homes, shops and vehicle use across 110V and 220V markets.

* Ratings per the supplier specification sheet. Capacity is stated in Ah per the sheet (500W grades also carry Wh values: 288/345/445Wh); pack voltage for the ternary chemistry was not stated — confirm when quoting. AC output is dual-voltage 220V 50Hz / 110V 60Hz with CN/US/EU plug options per the sheet; AC socket count/location was not shown on the product photo — confirm with the sales team. CE, FCC and RoHS markings are printed on the shell; certificates to be confirmed for your market before ordering. All versions ship with the charger and manual.
Frequently Asked Questions
What can these units power during an outage?
A 300W unit covers a POS terminal, ticket printer, router or till lighting; a 500W unit adds a small cooler, monitor or CCTV. Pure sine wave AC is safe for sensitive electronics, and DC 12V/USB outputs run lamps, routers and phones directly.
How fast does it switch to battery?
The UPS function switches in ≤5ms — fast enough that computers, POS terminals and routers keep running without rebooting when the grid dips or fails.
Which version should I choose?
Match runtime to the load: 18-26Ah suits short outages and light loads; 31-40Ah (or the 500W grades, up to 445Wh) carries heavier appliances and longer backup. All seven share the same shell and panel, so one listing covers the whole range.
Is this 110V or 220V?
Both. The series supports 220V 50Hz and 110V 60Hz with CN/US/EU plug options — confirm the configuration for your market when ordering. Charging works from mains, solar or a 12V car socket.
Can I order with my own brand?
Yes. The shell is neutral (no brand printed) and OEM-ready; custom silkscreen, colour, packaging and carton marking are available with MOQ. Contact our sales team for OEM terms.
What is the export packing?
Five units per carton, carton size 52 × 36 × 42cm. Full export documentation (commercial invoice, packing list) is provided with every order.
