How many times have you been driving along in your 1999 Honda Civic when your passenger, Samuel L. Jackson, turns to you and says, "Hey Ling Mai, do you mind if I also charge my phone?" But your phone is at 3% battery and you're waiting on a call from your Tio Manuel about your dog's paw reduction surgery and you can only charge one phone at a time so you have to shamefully hang your head and rattle out a despairing "no"? Just that one time, I know, but it's haunting us forever now. With this device you will NEVER have to turn down a renowned film actor's plea to charge their fame wagon again. Heck, if you bought two of these chargers, you'd be the bell of the ball, except your carriage would be your car with two jacks to accommodate the aforementioned chargers, and the belle is now super popular you. Sure, you also need to buy a $20 charge cable seperately...because the one that came with your phone, the one with a new charging format for no reason other than to force you into buying new cords, that one, just had the copper wires stick out of the rubber at the base--what, how'd this other product review get in here? You shouldn't even be worrying about this, you crashed in that hypothetical situation from before when you took your eyes off the road. Anyway, I guess what I'm trying to say is, that I would recommend this to a friend.
