July 2018 I have the same problem. I bought the original DK-39 and it literally discharges the Tablet. I had tried the small magnetic charger two years ago. I had the same problem but I think that it was not a sony product. Now that I decide to buy an original sony product I still have the same problem. I have so many sony products at home. I was thinking of buying a new phoneas a Sony Fan but i think is time I start looking at the competition for a new phone where accessoiries will be really compatible. The Tablet is fine. Sony repairs are good and thrustworthy but I am really deceived with the magnetic charger. Still looking for a solution though.
