The Poweradd family-sized USB wall charger power adapter is capable of pumping juice into five devices at once. It's a compact way to get as much use out of a single power outlet as you can, and today it's available on Amazon for just $12.99 after a coupon code that shaves an additional $3 off its current $15.99 sale price. To get the discount, enter 5N4O4IUS at checkout.
Of the power adapter's five USB ports, two provide an output of 2.1A, one offers 1.3A, and the remaining two pump 1A each. The package includes the 5-port adapter and a five foot long power cord. That's long enough to get some space between the wall and the massive jumble of cables that will ensue from putting this thing to proper use. Will the time spent untangling those cords undo the time saved charging multiple things at once? I don't know, but here's the link.
