Our verdict: ✓ KEEP

Research supports the standard 268Wh RIVER 3 Plus for buyers who need portable power for modest loads while camping, traveling or backing up a small office setup. It offers a 600W rated AC output and a compact 10.4 lb design, but the battery capacity limits runtime on higher-wattage devices.

What it does well

It provides three AC outlets, USB-A and USB-C charging, a 12V car outlet and pass-through UPS functionality. EcoFlow lists under-10ms switchover and up to 600W rated output for this family; verify the product label and included manual for the exact SKU before connecting sensitive equipment.

Who it is for

Road trippers and campers who need to recharge personal electronics or run modest compatible loads, and home-office users who want short backup power for a router or computer.

Who should skip it

Anyone expecting long runtime from heating appliances, large kitchen equipment, or other loads above 600W should choose a larger station. The standard 268Wh battery is for short-duration portable power, not whole-home backup.

KEEP if

You want portable power for short trips or a small backup load. The specific standard model listed by Best Buy is 268Wh and 600W; Popular Mechanics tested a 268Wh version and reported about 10.4 lb. Check the SKU carefully: the RIVER 3 Plus Wireless is a separate 286Wh variant.

Know before buying

Popular Mechanics’ hands-on review found the 268Wh RIVER 3 Plus compact for its output, and measured a full AC recharge in just under 50 minutes. The review also flags the practical trade-off: a small battery does not run high-wattage appliances for long, and the unit has only one USB-C port. Performance and runtime depend on the connected device and conditions.

Why it earns a KEEP

It combines useful AC output, several charging options and UPS capability in a light, portable package. It earns a KEEP for short-duration modest loads when portability matters. It is not a substitute for a high-capacity backup station.
