Phones these days can use up a lot of power, especially when using GPS and playing music simultaneously. That's why it's important to have a car charger you trust. Aukey is one of the most popular choices for third-party chargers, and now Amazon has a killer deal on the company's 30W fast charger that has USB-C and USB-A plugins. The Dual PD charger retails for $14.99 usually, but right now there's a coupon you can use to get it for just $7.49 — 50% off.
