New moms and dads take lots of pictures. Just check your Facebook or Instagram for anyone you know with a baby if you need proof. With all the snaps of baby and selfies that moms and dads take, it can be hard to keep your phone charged while out for a walk with your little. This is where the 4moms Moxie stroller comes in. It looks like one of those old-fashioned prams, but it has some cool power-generating tech inside.
