Supersized power in the palm of your hand.
Compatibility maximized
Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn't limit your charging speed.
Packed with power
From camping trip to disaster zone and everywhere in between, the 2nd Generation Astro E4 multiplies your battery life to keep you powering on for days. With enough charge to feed your smartphone 3-6 times (depending on its battery size), just put this power pack in your pocket and leave your charging troubles behind.
A very handy design
Slimmer, sleeker, smarter - enjoy the world's most powerful portable battery more than ever before. The revamped E4 rests nicely in your palm and sports a single button perfectly positioned for your thumb. Check the power level with one simple press or turn on the flashlight by pressing for 3 seconds.
