The charging time of the Powerstation with a 100 watt solar panel is around 5 to 6 hours under optimum sunlight conditions. This results from the capacity of 512 Wh and the realistic output of a 100 watt panel, which in practice delivers around 100 watt hours per hour in full sunlight.

A field report shows that a full charge is possible in around 2.5 hours with more powerful solar panels (up to 220 watts), which extends the charging time with a 100 watt panel accordingly. The charging time can vary depending on the intensity of the sun and the type of connection, but is typically within the specified range for a 100 watt panel.
