Machine washable. The solar panels enable you to recharge your USB compatible devices on the go, either while wearing the jacket or with the panels removed. You can use the solar panels to charge your devices without attaching it to the jacket so long as the panels are exposed to light, preferably direct sunlight. The solar panels charge a small battery - about the size of a deck of cards. The battery powers your device almost immediately after the solar panels are exposed to sunlight. Once the battery is fully charged, the panels can be removed and your portable electronic device can tap into the stored power. Typical charge times in direct sunlight range from 2-3 hours, but direct sunlight is not required.
*Note: The device must be USB compatible, and be designed to charge using USB connections. Please consult device manufacturer’s information to determine whether it can be charged via USB cables. NOTE: USB cables are not included.
