TKDY 18V 1A Power Supply Cord DC Plug, 110-240V AC to DC 18Volt US AC Adapter for 18Vdc 300mA 500mA 750mA 100mA~1000mA Equipment (Not 18V Battery Charger).

This is a review of TKDY 18V 1A Power Supply Cord DC Plug. I ordered this product to power an electric ball valve. Once I set up everything, I wondered why the valve would not work, then found the two terminal block adaptor had no power. Every other adaptor worked fine. The transformer puts out the proper voltage when checked with a multimeter. I was able to make this item work by modifying one of the other adaptors. It does output the proper voltage but since the part I needed for my use did not work and required me to modify another adaptor, I am rating it 2 stars.

We lost the power adapter/charger for our percussion massager. It requires 18V and at least 0.8 A. The default barrel connector on the adapter did not fit, but one of the included adapters did and it works great to recharge the battery in our massager.
