EcoFlow RIVER 3 UPS at a Glance
A Closer Look at the EcoFlow RIVER 3 UPS
The EcoFlow RIVER 3 UPS is a compact portable power station for the smaller essentials that matter during a short power cut: Wi-Fi equipment, laptops, lighting, phones and suitable home-office devices. Its 245Wh battery and 300W continuous output make it easy to store and move, while keeping expectations realistic. Use the Power Calculator to check your own device wattage and required duration.
UPS mode automatically switches a connected compatible load from mains power to the battery in under 10ms when the supply fails. That is useful for suitable routers, network equipment and smaller office electronics, but device requirements vary. It is not a medical UPS, does not guarantee that every computer or server will tolerate the transfer, and remains limited by its 300W continuous output and available battery capacity.
For longer refrigeration backup, several appliances or higher loads, compare larger portable power stations or explore Home Backup Power. For compact emergency planning, browse Emergency Power Kits and the wider EcoFlow range.

FAQs
What can the EcoFlow RIVER 3 UPS power?
It is best planned around compatible low-power essentials such as Wi-Fi equipment, laptops, phones, LED lighting and smaller electronics. Keep the combined continuous load within 300W and check start-up demand before connecting any appliance.
Is EcoFlow RIVER 3 UPS suitable for UK power cuts?
Yes, for shorter outages and selected essentials. Its 245Wh battery is useful for compact backup, but it is not intended for whole-home use, several high-load appliances or long-duration heating and cooking loads.
What does the UPS function do?
When connected to mains power with UPS mode operating, it can switch a compatible connected load to battery supply in under 10ms if the mains fails. Suitability still depends on the device power demand and its tolerance for transfer time.
Can EcoFlow RIVER 3 UPS keep Wi-Fi running during a power cut?
Usually, provided the router, modem or fibre equipment stays within the output rating and the external broadband service remains available. A typical router may run for an estimated 9-12 hours, but equipment demand varies.
Can EcoFlow RIVER 3 UPS power a fridge?
Some compact fridges may fit the output rating, but compressor start-up demand and duty cycle vary widely. With only 245Wh of capacity it is not the preferred choice for long refrigeration backup; consider a larger power station.
Can EcoFlow RIVER 3 UPS charge from solar panels?
Yes. It accepts up to 110W solar input within an 11-30V DC range and 8A limit. Use a compatible panel and cable; UK charging performance varies with sunlight, shade, season and panel angle.
How portable is EcoFlow RIVER 3 UPS?
It weighs approximately 3.55kg and measures 25.5 x 21.2 x 11.3cm, making it easy to store or move between home, desk, car and campsite.
How quickly can EcoFlow RIVER 3 UPS recharge?
Maximum AC input is 305W and a full mains recharge takes about 60 minutes under specified conditions. Solar can recharge it in as little as approximately 2.6 hours in ideal conditions.
What warranty does EcoFlow RIVER 3 UPS include?
The EcoFlow RIVER 3 UPS includes a 2-year manufacturer warranty, subject to the warranty terms.
Should I choose RIVER 3 UPS or a larger power station?
Choose RIVER 3 UPS for compact, easy-to-store backup of low-power essentials. Choose a larger station when you need longer refrigeration support, several appliances, higher continuous output or substantially more stored energy.
