iPhone 5s Case with a Built in Outlet Lets You Charge Cord Free Josh Smith01/06/2014 The Prong PocketPlug is an iPhone 5 and iPhone 5s case with a built-in charger that allows you to charge anywhere there is an outlet, even if you don’t have a cable with you. This iPhone case launched first on KickStarter, but is now available at retail outlets and online direct from Prong, so there is no waiting for this nice case option to arrive on the market.Advertisement While there are many battery cases and a lot of users will put the Lightning cable in their pocket, purse or backpack the Prong PocketPlug is a handy way to stay charged while on the go. This iPhone 5s case has a built-in plug to charge at any outlet, without a cord. When in your pocket the prongs fold flat to fit the hand friendly design of the case though they are still visible which is an interesting look that users will love or hate.Advertisement If you need to charge up, flip the prongs out and plug into any outlet for a fast top off. The Prong PocketPlug sports Worldwide compatibility of 100-240V and 50-60Hz so travelers are good to go without a cord in hand.Advertisement Even with the ability to plug the iPhone right into an outlet, this may not be the best way to charge the iPhone at night in a hotel, so there is also a Micro USB port that allows users to charge up the iPhone in the PocketPlug case with a cord. This is a better fit for charging at night if you plan to also use the iPhone while it is charging. The Prong PocketPlug is an iPhone case that includes a plug to charge fast. The case itself is made of polycarbonate and looks like it will hold up well to wear and tear of daily use. The bottom of the case is designed very similar to the iPhone 5s battery cases, which cover the speaker and microphone to make room for the built-in lightning connection. This design focuses the sound forward towards the user which generally delivers a better experience. The iPhone 5s and iPhone 5 version is $69.95 and an iPhone 4 and 4s version is $59.95 and a Samsung Galaxy S3 version is in the works.
