Seems to deliver stable 5V (approx) power under a wide range of input conditions. However, the efficiency is not particularly high at low currents, as would be expected. Attached is a table of efficiency calculations using my non-calibrated equipment. No load current is 5mA which is a bit high for my liking. John from Ontario, Canada
