Today, Amazon has a great deal on the Anker PowerPort Qi 10 wireless charger. It's a Qi wireless charger that is getting $8 knocked off of its price when you use the promo code BEST2539, bringing the price down to just $18.
The Anker PowerPort Qi 10 is a great wireless charging pad to pick up, since you can set it on your desk and have it charging your smartphone while you're at work. It does support fast wireless charging, for Samsung smartphones as well as iPhones. Additionally, this is a single-coil wireless charger, so it's not as large as some of the others out there, but that also means you can't charge more than one at the same time with this one. Additionally, it should still work through the case on your smartphone, as long as it's not an overly thick case.
