I recently bought the Imperial Dabman D20 radio alarm clock - but it won't charge my Samsung S20 FE 5G (keeps breaking after a few seconds). Question: is the Pure Siesta Charge compatible with the Samsung S20? Question: is it possible to dim to zero or 5%? The brightness often bothers me when I'm sleeping... Question: how is the sound? Are you satisfied with it and is it enough? Thank you very much for your experiences!
