The need to stay plugged-in is becoming ever more important so the ability to charge electronic devices on the fly is key. The Supercharged 4.5LS comes equipped with a Philips Power Bank 10000 mAh - a lithium battery capable of powering your portable music speaker or recharging your electronic devices. The Power Bank has two USB ports, one standard and one rapid-charging, allowing the recharging of multiple devices at once.
