Try this battery in your backup planWhere it belongs in your plan
Its 768 Wh nominal capacity describes stored energy. The 800 W continuous rating describes how much AC power it can supply at once. A long, low-power load and a brief, high-power load ask different things of this battery.
Before you choose
Start with watt-hours for runtime, then check continuous AC output, startup demand, and the limits of each outlet.
Work through the power-station checklistWhat stood out in testing
OutdoorGearLab liked the RIVER 2 Pro’s compact size, quick charging, and four AC outlets. Those features make it easier to move a modest backup supply between rooms or take it on a trip.
Testing found less usable energy than the nominal capacity, along with noticeable fan noise and limited solar input. Read the full findings before choosing it for a quiet room or long stay.
