What this does and doesn't tell you
- This is an estimate. Real results vary with the power station, the charger, the temperature and how old the batteries are.
- Check that the power station's AC output (W) is higher than the charger's input watts, shown on the charger label.
- Charge in the shade, on a hard surface, away from anything flammable. Only use the battery maker's charger.
