AUKEY's popular USB-C car charger is currently on sale, coming in at just $7. That's good for 65% off of its regular price of $19.99, making this a pretty incredible deal. You will need to use the promo code 7F87GCAW at checkout, to get this price, however.
This car charger from AUKEY is a 3-port car charger, with two USB-A ports and then a USB-C port. This is great if you have a USB-C to USB-C cable available for charging your smartphone and such, but there are also two other USB ports for charging different gadgets. Now unfortunately, this does not support Qualcomm's Quick Charge 3.0 or earlier versions in the USB-A ports, but it does have AiPower included, which is basically adaptive fast charging. This means that it can charge your phone at up to 2.4A speeds, depending on the phone. What it'll do is talk to your phone to see if it can handle the extra speed without causing damage. Which is definitely a good thing on both fronts. On the USB-C port, you do get Quick Charge 3.0 support, which works on a number of smartphones like the HTC U11, Moto G5 Plus, Moto Z2 Force, Moto Z2 Play, LG G6, LG V30 and many other smartphones - in fact most smartphones with a Qualcomm chipset do support Quick Charge 3.0.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year (or $49/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
