Greater energy efficiency thanks to GaN technology

The EcoFlow RIVER 3 UPS utilizes advanced gallium nitride (GaN) semiconductors, enabling higher energy efficiency than standard silicon components. GaN technology, popular in modern 5G networks and electric vehicles, reduces energy loss, ensuring stable and quiet operation. As a result, the RIVER 3 UPS stands out for its compact size, longer runtime on a single charge, and lower noise level, making it exceptionally functional and efficient.

High power for demanding devices

The EcoFlow RIVER 3 UPS delivers up to 300 W of power, which can be expanded to 600 W in X-Boost mode. This enables seamless operation of devices with higher power demands! This means the station is perfect for powering equipment such as electric stoves, portable heaters, or portable refrigerators—ideal for camping. But the possibilities don’t end there. GaN technology extends the runtime of devices with a power rating of up to 100 W by as much as 92% compared to competing models—enjoy their reliable operation for as long as you need!

Multiple Ports Available

The EcoFlow RIVER 3 UPS is equipped with several different ports, allowing you to power multiple devices simultaneously. You have access to a 300 W AC outlet for home appliances and laptops, two 12 W USB-A ports, one 100 W USB-C port, and a 12.6 V 100 W car outlet. This setup allows you to conveniently charge phones, tablets, cameras, fans, and other devices! This makes the station perfect for trips, outdoor events, or emergencies.

Don’t worry about noise

GaN technology not only increases the station’s energy efficiency but also significantly reduces noise levels, which in the RIVER 3 UPS model are as low as 30 dB. This makes the device perfect for any situation where silence is needed—you can use it, for example, to power night lights, chargers, and other small devices without worrying that it will disturb your rest or disturb the peace of other household members!

Be prepared for unexpected power outages. The station supports a UPS function, allowing it to automatically switch to emergency mode in less than 10 ms. It is therefore able to provide effective protection against data loss or equipment damage! Such a short response time is extremely important for devices that require a constant power supply, such as computers or NAS systems. What’s more, the EcoFlow app will keep you up to date—smart notifications will inform you of all power outages.
