Review on Waterproof DC-DC 12V to 5V 3A Micro USB Converter: Ideal Power Regulator for Car Smartphones by Matthew Perez

Revainrating 4 out of 5

Works with alarm keypad

Bought this item to connect my alarm keypad. Works great and was great to install everyone. The only thing to know if you buy it for the same reason is that the 90* head on the micro USB side makes it difficult to connect to the ring interface. This is not due to the product and therefore there is no star deduction.

Pros
  • Hands-free operation
Cons
  • No power
