No Need to remove the USB Car Charger once you've plugged it in and who isn't always looking for some extra time to charge their devices. This car adapter works with Smart Phones, MP3, and all other smaller devices supporting output power of 1 Amp. Also, an extra big imprint area means your brand is in front, center and plugged in. Use your existing devices' cable or ask us for an optional adapter but always remember: Charge it now and use it later!
