Not 3A, does not power Rasperry Pi

At 3A the voltage drops to 4.75VDC. To save 5 volts, the maximum current is 1.00. Might be ok for some devices but not for those that require accurate voltage.

Pros
  • Rugged construction
Cons
  • No power

Perfect for adding Wyze Cams to an existing 12v camera system

Had an old Lorex camera system with power/video wires throughout the house. Could use these DC adapters to replace 12V cameras with new 5V Wyze V3 cameras. Works perfectly!

Pros
  • Good value for money
Cons
  • Update available

Arrived unsuccessfully - power accessories

Only one of the USB ports provided power. The other one put out 4.8v at light load :( This is the minimum for USB. It was replaced within 1 day of my complaint :) The replacement works fine at 5.1v at half load. If this goes on for a few months I will upgrade to 5 stars. Anyone can send in a broken device.

Pros
  • Lots of positive emotions
Cons
  • Security

Proper nutrition ring keyboard!

Does the job it is supposed to do as a ring power source for keypads from an existing wired security alarm keypad. Acts as a permanent power supply over existing cables, reducing power to the level required by the ring system. Never worry about charging batteries or exposed keyboard cables again. Very easy to wire knit!

Pros
  • Free for educational purposes
Cons
  • Not bad, but...

Ideal for installing RING Keyboard

I bought these to convert my existing 12vdc supply from the alarm panel box to 5v with a USB micro adapter for my ring alarm keypads. Installation was easy: I attached a 12-volt cable, a screw-type connector, plugged the micro-USB into the Ring keyboard, and just hung the converter on the wall. I now have constant power for the ring keyboards. . In the event of a power outage in the home, the internal batteries will take over and work. SUPER EASY!

Pros
  • Absolutely amazing!
Cons
  • Quality
