EcoFlow RIVER 3

The EcoFlow RIVER 3 is a compact 245Wh LiFePO4 portable power station with 300W continuous AC output and X-Boost support for loads up to 600W. EcoFlow positions it as a small-footprint backup and travel unit with two AC outlets, two USB-A ports, one 100W USB-C port, and a 12.6V car socket so it can run up to six devices at once. AC charging reaches 0-100% in about 60 minutes, while solar input tops out at 110W for as fast as roughly 2.6 hours in ideal conditions. EcoFlow also highlights under-20ms UPS switchover, sub-30dB operation for always-on use, IP54 battery-pack protection, and an LFP pack rated for 3,000 cycles to 80% capacity. At 7.8 lb, it fits compact camping, router backup, and light emergency-power use. Weight: about 7.8 lbs.
