There's a deal over at StackSocial you might want to take advantage of, but you'll have to hurry. The ZeroLemon SolarJuice 10000mAh Battery is on sale for $26, down from a regular price of $50. The deal on this solar-powered battery is only good for the rest of the day, though.
When the battery in your phone isn't good enough, there's a plethora of external batteries available to pick up the slack. The ReVIVE ReStore Q10x is a 10,000mAh unit that usually costs about $35, but it's on sale at just $19.99 for the next few days. It's available with Amazon Prime shipping too.
Most portable external batteries make it easy to charge up a phone or tablet when your power runs low, but what about a computer?

Samsung wants your Galaxy phone or tablet to be the backup battery for other stuff, like a Gear watch, via the brand new Power Sharing Cable. It's a little double-sided MicroUSB cable that allows one gadget to charge another, without any AC adapter or portable battery pack. Read More
Technology in general and mobile tech in particular is on a rapid march forward, but there's a bottleneck that's holding it back: batteries. For years lithium-ion batteries have been the best option for storing energy pound-for-pound, but they've hit a wall - now we can only get bigger batteries or make our gadgets more efficient.
