m.p (verified owner) –
These were a pleasant surprise… I was looking for a small converter for a project (needed 9V from a 12V power supply) and hoped these would do the job. They are a little finicky to set (go easy on the little potentiometer) but so have have been capable of supplying a steady 2A for an indefinite period of time with only some warmth. Running them at 3A for a long time would probably warrant a small fan or heat sink.
Until they make something smaller and/or more powerful, I think I’m going to always want to have one or two of these on hand.
