Have you ever tried charging your MacBook Air with an external battery? Yeah, it doesn’t work, because you can’t charge the thing through USB. So that’s why we’re intrigued by the ChargeTech Portable Power Outlet, which features a full AC outlet as well as a USB port for charging. That’s 12,000 mAh in a format that’s technically small enough to carry in your pockets. It’ll charge anything that requires less than 65W, and can power two devices simultaneously. Normally you’d pay $270 for this, but it’s $185 after today’s rebate.
