If you drive a tiny car like I do, you know the struggle of a long car ride, two passengers, two phones, and only one power port. If you'd like to alleviate that frustration, head on over to Amazon. Today you can grab a Tronsmart car charger that has two ports for just $7.99 with a coupon. The charger is compatible with Quick Charge 2.0, and on both ports to boot. If that's not enough to convince you, they're throwing in two MicroUSB cables for free.

To take advantage of that low price, add the Tronsmart charger to your cart, then check out and apply the coupon code "DUALPORT" to bring the price down from $19.99 to $7.99. That's the lowest price that this particular accessory has had so far - last month it was slightly more expensive during the big Tronsmart sale. Naturally, Amazon Prime customers can get free two-day shipping, which will hopefully get the charger in your hands before you have to leave Grandma's house.

There's nothing particularly fancy about this charger beyond its functionality, but the extra cables and low price make it a good deal. (It doesn't hurt that the design omits those annoying, eye-searing LEDs.) There's no limit on how many chargers you can purchase at the reduced price, but there's no word on how long the coupon code will be valid.
