I bought one of these after a month it failed, it had not been abused in any way. used from 5 to 20 volts approx 1-2 amps when it was used only about one hour a week. Best Buy replaced it with a new one.The new one has now failed with similar use. With nothing connected to it started showing over current condition and the voltage indication would drop to1or 2 volts. Now Best Buy shows it is too late to return.If you are looking for a power supply buy another brand. This is coming from a retired engineer.
