Looking at the Jumper Card from the top with the connectors popped out, sporting 3 different connection types, you can see why I call this the "Swiss Army Knife" of portable chargers:
It measures 3.54 x 2.24 x 0.25 inches. By comparison, a credit card is 3.34 x 2.12 x 0.030 inches. So how well would this do in a wallet? That depends. If you use a tri-fold wallet, that obviously won't work. As for bi-fold wallets, it does work if you don't mind having a slight George Costanza wallet. That said, if you don't have many credit, membership, or gift cards stashed in your bi-fold, then the Jumper Card actually fits pretty well. Of course, the device is portable enough for pocketbooks, shirt pockets, pants pockets, laptop case, or any travel bag.
Sporting the three most popular connectors for mobile devices and gadgets: microUSB, Apple's Lightning connector, and the 30-pin iPhone connector all on a single adapter comes in super-handy. But that's the only trick up this device's sleeve. It also sports a bright blue LED that passes through two clear plastic orbs. Here's a profile view with the blue LED light turned on and a Papermate pen for scale:
