AC180
A little more nominal storage than a 1,024 Wh model with the same 1,800 W output class. Measurements show whether that difference matters for your schedule.
- Nominal storage
- 1,152 Wh
- Continuous AC output

Try this battery in your backup planWhere it belongs in your plan
Its 1,152 Wh nominal capacity describes stored energy. The 1,800 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
PCWorld’s load testing found strong AC efficiency, including 970 Wh delivered during its 800 W test. Ung also valued the app’s offline operation, useful when a power cut takes the router down too.
The unit was relatively heavy for its capacity, and DC efficiency was less impressive. A result at one test load does not predict every device’s runtime.
