The power's out. This road trip will never end. Camping, again? Fine.
Whatever the reason, sometimes you just need extra power when there's no outlet in sight. In those instances, you're going to want the biggest, fattest external battery pack you can find. And if you have to share it, or you have multiple devices, then you're going to want something with more than one USB port.
If you head over to StackSocial and happen to live in the US, you can currently get a Limefuel LP200X battery pack with a whopping 20,000mAh of juice. That's enough to recharge your average smartphone at least four or five times, with the number varying depending on just how much junk your handset has in its trunk. The site's only asking for $34.99, significantly cheaper than the usual price of $85.
In addition to the Limefuel LP200X's dual USB ports, the pack has a built-in flashlight and a digital display that shows you how much power you have to work with before needing to recharge. The unit itself is slim, taking up not all that much more space than a Galaxy S5 with a Mophie case.
This sale will end in six days. Shipping is free, but the battery pack could take 3 to 4 weeks to actually arrive at your door.
