Overview
The EcoFlow RIVER 2 is the compact power station for RV and portable communications kits. It is not the biggest battery in the catalog, but it is light, fast to recharge, and large enough for the radio, phones, hotspot, and short Starlink Mini sessions that define a mobile kit.
Pros & Cons
Pros
- 0–100% charge in 60 minutes via AC — fastest in class for sub-300Wh stations
- 256Wh LFP battery rated for 3,000+ cycles (~10 years daily use)
- 300W AC output handles most consumer electronics including radio chargers and small appliances
- Lightweight at 7.7 lbs — 30% lighter than comparable stations
- 5 charging inputs: AC, car 12V, solar, USB-C, generator — flexible off-grid recharge
Cons
- 256Wh capacity is modest — Starlink Mini at ~30W idle drains it in ~8 hours continuous
- 300W AC output excludes high-draw appliances (AC units, microwaves)
- No built-in waterproofing — needs protection from rain in open van/truck-bed use
- Currently shows as sold-out on EcoFlow's own shop; Amazon availability varies

The Right Size For Mobile Comms
A 256Wh station is small by home-backup standards, but it makes sense in a rig. It can run a radio charging station, top off phones, power a small router or hotspot, and give a Starlink Mini a measured session without hauling a 25-pound box for every weekend trip.
The RIVER 2 also uses LFP chemistry, which is a better fit for gear that may cycle often. It charges quickly from AC when you get a shore-power window and can take solar or vehicle charging when the rig is moving.
Where Capacity Runs Out
Do not buy this expecting all-night satellite internet plus lights plus fans. A Starlink Mini can drain a small station in a single working day, and high-draw AC loads are out of scope.
The honest use is scheduled power: bring the satellite link up when you need it, charge the handhelds and phones, then shut down high-draw gear. If your kit needs overnight medical-device backup or a household storm hub, move to a 1kWh-class station.
Kit Role
In the RV and van kit, the RIVER 2 is the middle buffer between vehicle power and communications gear. It keeps the comms stack independent from the main house battery and gives you a visible state of charge, which is what prevents silent power drift during a long parked stretch.
Our Verdict
The EcoFlow RIVER 2 hits the sweet spot for RV kit builds — compact, lightweight, LFP chemistry for longevity, and fast enough to top off overnight. At 256Wh it comfortably runs the MXT575 radio plus phones and a hotspot all day; pair with a 110W solar panel for indefinite off-grid operation. Specifically recommended as the power source for running Starlink Mini off-grid.
