10 - English Setup Connecting to AC power Before using your Bose Â® SoundLink Â® Mini speaker the first time, connect it to AC (mains) power and charge the battery. You can connect the power supply cord into the charging cradle, or directly into the speaker. While the battery is charging, you can begin using the speaker.
Ann is completely right. Given the alternative energy aspect of solar lights it seems a bit funny to have them charged by electrical lighting. Given enough direct and reflected sunlight in a room, they could be charged indoors. The stored charge wouldn't be as efficient as if they were in full sunlight though.
If the solar panel receives direct sunlight for the entire day, the light has enough power to illuminate your landscape all or most of the night. Solar landscape lights typically use light-emitting diodes (LEDs) as the light source, which are energy efficient and make for a longer-lasting light than regular bulbs. The brightness of your solar light depends primarily on the number of LEDs within the unit.
