Andy 4 Just received. Well packed in bubble wrap.Size is very nice. about the size of two small Japanese comic books.Has a green LED to indicate power on.The output voltage can be fine tuned via a small variable resister.The variable resister is a little difficult to reach as it is half hidden by the power connection terminals. The terminals have a fold down & locking plastic cover for safety but you could touch the mains terminals if unlucky.After maximum possible adjustment via variable resister...Results:5v = 5v Great!12v = 12.2v Basically Great.24v = 25.8v A bit high. Can't tune lower than that!Ampage I haven't test yet.
