Jumper Card - The Swiss Army Knife of Portable Chargers

Originally posted on VoIP & Gadgets Blog, here:

The Jumper Card is a very unique portable charger that meets just about every portable charger requirement - it's small/portable, it has decent power for its size, and it sports multiple connector types, including MicroUSB, Apple's Lightning, and iPhone 30-pin connectors. Launched on Indiegogo, the founder Eli Regalado sent me a review unit to check out.

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, shift 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:


  • 480mAh battery [iPhone 5 has 1440mAh so 1/3rd the "juice"]
  • 1/4-inch thick
  • Overcharge/discharge protection
  • Charging light indicator
  • About the size of a credit card
  • MicroUSB, Apple's Lightning, and iPhone 30-pin connectors
  • Meets military specs
  • LED flashlight and power on/off
An important question buyers will want to know is how long the Jumper Card will hold its charge. The answer according to their FAQ is one year. The FAQ also states that the Grade A Hi-power Lithium Polymer battery can be charged 300 times plus. Importantly, you can connect the USB connector to your PC/laptop, as well as the device you are charging and the Jumper Card will be charging at the same time you can sync files from your device. So how did the Jumper Card perform in my tests? Well, I got about a 15% boost in my phone's battery charge, which is plenty for an emergency power situation. The Jumper Card is a well-designed and well-executed produc that covers just about every need you would have in a portable charger. At just $25, this "Swiss Army Knife" of portable chargers should be added to every gadget-lover's arsenal!
