OVERVIEW
The UDPOWER S1200 is a compact but high-performing portable power station designed for both home backup and outdoor use. With a 1190Wh LiFePO4 battery, 1800W rated AC output, ultra-fast charging, and a UPS function (<10ms switchover), it’s a serious contender in the mid-range category.
I’ve tested it extensively off-grid, powering everything from a CPAP and laptop to a 55" TV, air pump, and even a small fridge. Here’s what I found.

PERFORMANCE
Power Output
No problems running multiple devices simultaneously – a laptop, router, and 32" monitor only used ~120W combined. I also tested a 700W coffee maker, and it handled the startup surge like a champ.
Charging
Using both AC and USB-C together (165W + 65W), I got a full recharge in about 4.5–5 hours. With solar input (~150W panel), I topped up ~60% over 6 hours of good sun.
UPS Function
The <10ms switchover worked great. I simulated a power outage with my router and PC connected — absolutely no disconnect or shutdown. Perfect for home office or NAS setups.
Fan & Noise
One of the quietest I’ve used. It rarely spins up unless charging fast. Under 25dB in most cases — basically silent at night.
WHAT I LIKE
- LiFePO4 Battery: Long cycle life and safer chemistry.
- 1800W Peak Output: Enough to run small kitchen appliances or power tools.
UPS Mode: Game-changer for blackout-prone areas or work-from-home setups.- Solar Compatibility: Works well with a 100–150W solar panel.
- Low Noise: Virtually silent operation.
Port Selection: 15 output ports including wireless charging!
WHAT COULD BE BETTER
No display of real-time charge input/output in watts — just battery %.
No expandable battery option (yet).
AC fast charging is solid but not ultra-fast like 1000W wall charging units.
WHAT’S IN THE BOX
- UDPOWER S1200 Power Station
- AC Charging Cable
- Car Charging Cable
- User Manual
- Warranty Card (5 Years)
FINAL VERDICT
The UDPOWER S1200 is an underrated powerhouse that holds its own against bigger brands at a better price point. If you need reliable mid-size backup for your home office, RV, CPAP, or weekend camping — and especially if quiet, clean power and UPS switchover are priorities — the S1200 is an excellent pick.
