Outside of the credit cards you use to purchase all those “must have” apps, it’s hard to find anything wallet sized that will improve your phone experience… except for this silver rechargeable card speaker. The 3.3″ x 2.2″ stainless silver speaker charges in two hours from any USB port and then outputs five hours of audio through a 3.5mm connection.
