It's important to keep your phone up and running throughout the day, but sometimes your phone can't survive all day on one charge. That's where the Kate Spade Slim Portable Charger comes in. Packed with an 1800 mAh capacity battery, this sleek, lightweight charger provides over eight additional hours of talk, text, and surf time. It's compatible with most devices that charge via USB, and is small enough to fit in any bag or purse. Simply connect your phone's USB cable (not included) to the charger, and your device will be powered up in no time. LED indicator lights let you know how much power the battery bank has and when it's time for a charge.
