Wallets' job description just keeps on growing. What used to be no more than a suitcase for cash and photos of your kids has now been tasked with carrying everything from credit and fro yo frequent patron cards to custom-fitted knives to, as we see here, custom-fitted phone chargers. The TravelCard is a last ditch reserve of Android or Apple phone juice condensed into a 2-ounce plate sized to fit perfectly in your wallet.
TravelCards come with either a built-in micro-USB or lightning cable and a 1500mAh power bank capable of delivering a 30% to 40% charge to phones on their death beds. At 3/16" thick they should add minimal bulk to your wallet.
TravelCards are available at a $10 discount for a limited time from Dude Exclusives.
