“A well-constructed power supply - I am a radio amateur, and some power supplies emit inteerference that affects radio, but not this one. In use it doesn't run too warm, and is solidly built, with a decent length of cable. Mine is powering a device with a previous generation board, the 4 series, and charging batteries, and even wit the device powered up, it still charges the batteries at a sensible speed. Don't go for second best, buy one of thse and have peace of mind about reliability and safety.”
