Besides the external battery charger sticks out there this has to be the smallest I have ever seen so far. This is really nice as it fits right into your wallet if you are a female, or in your pocket if you are a male. I like that is comes with a spot that holds everything nice and neat, including the apple lightning adapter.
This is one I can have in my purse for those just in case times, we try to check on our chargers at least once a week to make sure they are powered up. Great for power outages, vacations, or when you can't get to a electrical socket to charge your device.

- THE POWERCARD - A PERFECT COMBINATION OF POWER, SIZE & WEIGHT. Many products claim to be "the world's thinnest, lightest power bank". Usually that just means they don't have enough juice to actually charge your phone enough to use it. If you compare our ratio of weight (60g/2.1oz), to compact size (3.75 x 2.4 x 1/4 inches) to powerful charge (2500 mAh Real Capacity) you will not find a better external battery charger for emergency situations or those days where you need a little extra power.
NO MORE FUSSING AROUND IN YOUR BAG FOR ANNOYING CHARGING CABLES. A portable battery charger is not really portable if you have to also carry the cables that easily break or tangle. Our smartly designed external power bank has a built-in Micro USB and Apple Lightning Cable meaning you have everything need to charge your phone when you need it the most.
NEVER RUN OUT OF BATTERY POWER AGAIN. External battery packs are a great idea in theory, but we found that we never seemed to have them on hand when we needed them the most. To solve this we designed the PowerCard. Our lightweight design means you can always carry the charger with you whether you are out on business, travel or at a restaurant. Our A+ Li-Polymer battery cell (2500 mAh) means that you can depend on the PowerCard to fully charge almost all smartphones.
