EcoFlow revealed its latest power generation solutions at CES 2025, with the Delta 3 series power stations leading the pack. The flagship Delta 3 Plus features lithium iron phosphate (LFP) battery cells rated for 4,000+ charge cycles, with a total capacity of 3,024Wh and maximum output of 3,000 W. The unit's X-Stream charging technology enables 0-80% charging in 40 minutes when connected to AC power, while supporting 1,200 W maximum solar input. The base Delta 3 model offers similar specifications but with a 2,048Wh capacity.

For small-scale applications, the River 3 Plus delivers 1,200 W continuous output from its 512Wh battery pack. Operating at 30 decibels under normal load, the unit includes two 120 V AC outlets, three USB-A ports, and one USB-C port capable of 100 W output.

EcoFlow at the 2024 International CES unveiled the Delta Pro Ultra. This battery inverter-generator is roughly the size of a mid-large travel bag, and is lugged around with wheels and a retractable handle; but in order to power a whole home, there is a static component to it in the form of a wall-mount distribution board. The unit itself puts out four standard 110-230 VAC sockets, a large 16/32 A socket, and a single-phase input for recharging the battery. An LED segment display puts out realtime usage/recharging stats. We are working to get its battery and electrical stats, but we're getting to learn that for a mobile home or a camper, this thing has the battery capacity to power things for days, including some high-wattage appliances such as a microwave oven or a washer. We expect its continuous power output to be in the 5-6 kVA range, with three of these adding up to a typical 18 kVA 3-phase household load.

Smart battery generators were a recurring theme this CES. These are devices with large batteries—usually lithium ion—connected to an integrated sine-wave AC inverter, and other goodies such as direct low-voltage DC charging points for all your devices. These come in pretty handy as a replacement for small gas-powered gensets you take along for camping, as the battery drains much slower than the genset burns fuel at its lowest-load state; and many of these batteries include a means to recharge with solar power, using portable, foldable PV panels.
