Have you gotten the new iPhone 5s and need a battery pack to go with it but don’t feel like carrying around another product well today I am going to tell you about the TYLT Energi Sliding Power Case for the iPhone 5/5s this sleek protective impact resistant polycarbonate case with TPU bumper has a built-in battery which recharges to 2,350 mAH and will double your standard battery life you have on your phone now You will be able to charge, sync and back up data or even listen to your tunes while you have the TYLT power case on when you get your TYLT power case in the package will come a micro USB cable to charge/sync your case and device , a 3.5 mm cable to connect to your device to listen to your tunes Now this case does come at hefty price of $99 but remember not too many more power cases out there on the market like this very unique case Overall from my time with this case I really like it and I know now the Tylt power case is superior in design, material, quality and construction
