The power LED light appears with the push of a button to let you know the power status of your battery pack at a glance.
Even if you're not near a wall or car charger, you can recharge your device's battery with the convenient battery pack. The intelligent battery pack supplies power first, so you can remove the pack after use and still have a full battery on your device.
This portable power source gives you the extra power for more than two full recharges on the go. Take it with you when you travel to have back-up power when you need it.
