Can a Portable Power Station Run a Drone Battery Charger?
Yes. Drone batteries charge at 30-65W over USB-C — well within any power station's output. A 300Wh-class station refills roughly 8-10 DJI Mini batteries, or a full three-battery Mini set about three times over.
How Much Power Does a Drone Battery Charger Use?
| Metric | Range |
|---|---|
| Running watts | 30–65W |
| Startup surge | 30–65W |
| DC power possible? | Yes |
DJI Mini-class batteries charge at ~30W and hold ~20Wh; Air-class batteries want a 65W charger and hold 40-50Wh. Charging hubs top up batteries sequentially, not simultaneously. Everything in this class charges over USB-C PD.

FAQ
How many drone batteries can a power station charge?
Figure each DJI Mini battery consumes ~25Wh from the station including losses, and Air-class batteries ~50-60Wh. A 300Wh station is good for roughly 8-10 Mini charges or 4-5 Air charges; a 500Wh-class station nearly doubles that.
Do charging hubs charge all batteries at once?
No — DJI's hubs charge sequentially, topping up one battery at a time in priority order. Total draw stays at the single-charger level (30-65W), so the power station load is light; it just takes longer than parallel charging would.
Should I use USB-C or the AC outlet for drone charging?
USB-C PD directly from the station when your charger supports it — it avoids the inverter's ~15% conversion loss. If you use the drone's AC charging brick instead, everything still works; you just get slightly fewer charges per station.
