With more and more smartphones coming with Qi Wireless charging enabled, Qi wireless chargers are becoming more and more popular. Which is driving down the cost of them. They used to cost at least $50. Now we're seeing many of them around $15 or lower sometimes. Like the Anker PowerPort Qi Wireless Charger here. However, it's currently on sale for $15.99, but its normal price is around $59.99. So that's quite the deal.
This Anker PowerPort Qi supports the Samsung Galaxy S6, Galaxy S6 Edge, and many other smartphones out there. If it supports Qi, then this charger supports it. You can grab it from the link below.
