The Extreme has an integrated 4000mAh BATTERY PACK that will keep you going strong for up to 185% of your regular battery life. Simply press the button on the back of the case for 2-3 seconds to activate the lightning charger and when you’re juiced up hold the button for 2-3 seconds to stop charging your phone. The battery indicator tells you how much juice you have left. Talk for an extra 23 hours. Watch videos for 18 hours. Listen to music for 83 hours. The Extreme has an integrated SOLAR PANEL. Yep, an over 20% efficient mono-crystalline solar panel. Activate in sunlight to trickle charge and replenish battery power in the case’s integrated battery when no power source is available. New to the SLX7, we integrated a solar capture indicator - the more lights that are lit up mean the more solar energy you are capturing. 1 Hour Sun exposure = 10 minutes talk time restored to iPhone from case charge. Your SLX7 comes in innovative dry-box packaging: zero waste + crushproof, dustproof and watertight (IP-67) to store your wallet and other non-water friendly items.
