Sobrilli Drive Wired Earbud Adapter Changer - Noise Cancelling Premium Stereo adapters w/Mic, Ergonomic fit for Men & Women, Black

Its worked well so far. I can charge up my phone and tablet at the same time, more than once. It about the size of a pack of cigarettes, maybe a little longer. I just drop it in my purse and I'm good to go. Came in handy when I had jury duty.

I love Iit so much. Keeps me in a state of security that my phone's battery will never die
