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.
Solar spot lights like this one rely on energy from the sun to charge their batteries and provide light throughout the night. This means that there is no need to tap into the electrical grid for these lights to operate. The solar spot lights will work consistently, even if the whole neighborhood is dealing with a power outage.
