The Samsung Fast Charge Wireless Charging Stand drops from $69.99 to $23.99 with free shipping at TechRabbit. This is the lowest price we could find for a single one by $3. They're compatible with any smartphone with Qi wireless charging built-in, but the Fast Charge feature is only compatible with the Galaxy Note5, Galaxy S6 edge+, Galaxy S7, and Galaxy S7 edge. Other devices will charge at standard wireless charging speeds. There is no sales tax (except NJ).
