Amazon currently has AUKEY's very popular wall power strip which has two AC outlets and two USB outlets available for just $6.99, that's good for $7 or 50% off of the regular price. However, you do need to use the promo code 2XFITO5N at checkout to get that discount.
This wall power strip from AUKEY is a great one because it allows you to add two USB ports onto your wall outlet, while also keeping your two AC outlets there for other things to be plugged in. The USB ports do not sport Quick Charge 3.0, but there is support here for AiPower, which is AUKEY's proprietary technology. AiPower will charge your smartphone (or tablet) as quickly as it can without damaging the device. This is great for those that want to charge their smartphone quickly, but might be afraid of it overcharging or getting too hot and blowing up. That's not an issue with AiPower, and it is capped at 2.4A, which is not fast enough to really overcharge. There is also a shelf above the wall outlet, allowing you to place your smartphone there while it's charging, and keep it from just hanging down from the outlet, and give it a place to sit. That means this wall power strip is a bit thicker, but definitely worth picking up.
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.
