I received the charger yesterday. The concept is great, the design is great, functions well as a stand, can wirelessly charge in both a horizontal and vertical position as mentioned. However, a significant fault in my experience is it does not fast charge my Samsung Galaxy S10. It claims to have this ability, but in reality I’ve found it charges at a rate that is around 33% what my wired fast charger provides. As a result, especially if being used, the phone charges very slowly, and occasionally decreases in percentage depending on how heavy my usage is. I’ve tried multiple cords (including the original), ports, and fast charging bricks to confirm that it is ineffective as a fast charger, and all tests reinforced the charging speed as 1/3 that of my wired fast chargers. For accuracy and assurance, no cases were used during these tests, and I used two different S10 devices to perform my tests. However, it is possible that the one I received is not representative of all chargers.
