Title: jWIN JA-C52AC Adapter
Review: I have tried two different samples of this AC adapter which has an attractive price particularly with the settable outputs. Both samples failed to work as advertised. I tried using them with a Chamberlain intercom system that can be either battery operated or with an AC adapter with 12V input. These chargers made the intercom malfunction totally. Fortunately, when I disconnected the AC adapter, the intercom works fine on batteries and I will continue to use only batteries on the intercom. I did put a voltmeter on the output of each of these units and it came as no surprise to find that the output was not as rated but much higher. When set at 12V it was giving 22.8 V at the plug. When set at 6V the output was 11. Both samples behaved similarly and would not work with the intercom. This is junk and I will try to get Amazon to give me a refund on both units.
Is the review positive or negative?
