Can a Portable Power Station Run a Camera Battery Charger?
Yes — trivially. Camera chargers draw only 10-30W, and a mirrorless battery holds just 10-15Wh, so even a small power station recharges well over a dozen batteries per charge. Use USB-C where possible to skip inverter losses.
How Much Power Does a Camera Battery Charger Use?
| Metric | Range |
|---|---|
| Running watts | 10–30W |
| Startup surge | 10–30W |
| DC power possible? | Yes |
Mirrorless battery chargers draw 10-30W (Sony BC-ZD1: 15W single/30W dual; Canon 15-22.5W; Nikon up to 45W on Z8/Z9 chargers). A single battery holds only 10-15Wh, so each charge consumes 15-30Wh from the station. Most modern bodies also charge in-camera via USB-C at similar wattages.

FAQ
How many camera batteries can a power station charge?
A 300Wh-class station realistically delivers about 15+ mirrorless battery charges after conversion losses (each charge consumes roughly 15-30Wh). A 1000Wh-class station keeps a working photographer supplied for many days of shooting.
Should I charge via USB-C or the AC outlet?
USB-C PD when your charger or camera supports it — it bypasses the inverter and its ~15% loss. AC works fine for dedicated dual chargers; the totals are small either way.
Can I charge two batteries at once?
Yes — dual chargers like Sony's BC-ZD1 draw about 30W with both slots active, still a light load for any power station. Charging speed per battery is unchanged; you're just doubling the modest draw.
