Our answer
On our planning profile the DJI Power 1000 runs a router and modem for about 45 hours, or 36 hours if you keep a reserve back.
The checks behind this answer
Stored energy is the final check, not the first. Voltage, continuous output, and startup demand must clear before runtime means anything. Missing published evidence stays marked unverified instead of being treated as a pass.
| Check | Result | Why |
|---|---|---|
| Voltage | Clears | A router and modem runs on 120V and the DJI Power 1000 supplies 120V AC. |
| Continuous output | Clears | A 18W running load sits inside the 2,200W continuous rating, leaving about 12122% headroom. |
| Startup demand | Clears | The 18W start is covered by continuous output alone, so no surge rating is needed. |
| Inverter self-consumption | Unverified | This is a long, low-power load, so the inverter's own draw materially changes the answer. That figure is not published for this station. |
How the number is built
A battery holds back some of its rated capacity, and converting to household AC costs more on top. Of the 1,024Wh rated here, roughly 811Wh reaches the outlet under a conservative planning model.
That energy meets an average load of 18W, which applies a 100% duty cycle to a 18W running draw. Holding back a 20% reserve for battery age, cold, and a longer outage leaves 36 hours. These are calculations, not measurements from a test.
What we could not verify
These gaps are in the published evidence, not in the arithmetic. Each one is a reason to check before you depend on this pairing.
- Inverter self-consumption is not published, and it matters more than the appliance load on a run this long.
Before you rely on this
These limits decide whether this appliance belongs on a portable battery at all.
- Home internet service usually depends on powered equipment in the street or at the exchange. Powering your own router does not guarantee a working connection during a wide-area outage.
Replace our assumptions with your own
This is a small load that runs for a very long time, so the station's own inverter self-consumption can exceed the router itself. Check that figure before assuming days of runtime.
Add the ratings printed on each power brick, or meter the power strip that feeds your network gear.
