    Quality:

    I put this to the test and found it delivered a steady 13.67 volts DC at a continuous 3A draw with no audible "hash" in receiver and a clean wave-form on 'scope. It held voltage at 5 Amp draw as well as at 6A on a SSB transceiver. I will subject it to further abuse since it is on sale now!
