Amazon is currently selling one of the best sellers in the wireless charging category, AUKEY's Ultra Slim Qi Wireless Charging Pad for just $8.99. That is good for $4 off of its regular price, but this is only when you use the promo code AUKEYLC3 at checkout. That is a really good price for this charging pad, especially when you consider the fact that many other charging pads are typically priced over $20, regularly.
This wireless charger from AUKEY is a regular wireless charger, so there's no fast wireless charging here unfortunately. You'll be stuck with charging at 5W. Which is the speed that most smartphones support anyways. Samsung, Apple and Google smartphones that use fast wireless charging are still backwards compatible to 5W, and will still charge using this wireless charger. It'll just be a bit slower. Sure 5W is pretty slow, but you really only should be using a wireless charger at night when you are sleeping, so that the speed doesn't matter, as long as it is fully charged by the time you wake up.
AUKEY has done well in designing this wireless charging pad. It's black with a gray ring around it, which makes it look rather elegant. It is also a soft-touch charging pad, and that means that your smartphone will not slide off of the charging pad overnight, resulting in your phone not actually charging. Which can be a pretty big deal. Obviously since this is a Qi-based wireless charger, it'll work with all Qi-enabled smartphones. That includes the Google Pixel 3, Samsung Galaxy Note 9, LG V40 ThinQ and many more. It will also work with cases on the phone, up to about 3mm. In other words, it will work fine for a thin case and even a somewhat thick case, but something like a rugged case from OtterBox, forget about it. You'll have to remove the case to charge your phone. AUKEY does include a micro USB cable with this charger, but no wall charger. So you'll have to either buy one, or use one that's hanging out at your home. AUKEY also includes a two-year warranty with this ultra slim wireless charger, which is also a good look, in case anything goes wrong.
This 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. However, if you are in one of the select areas that has Prime Now, this is also available and you can get it within a couple of hours, if you are in desperate need. 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 $119/year (or $59/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. That includes Amazon Prime Video, Twitch Prime, and even some benefits at Whole Foods.
