## Description

desertcart.com: PlusRoc Waterproof 12V/24V to 5V Converter DC-DC Step Down Module Power Adapter Compatible with Raspberry Pi 4, Cellphone, Car (USB Type-C Connector) : Electronics

Review: Reasonable price, small size, easy installation - Functions great. Electronics are submerged in resin to protect from vibration for great durability. After installation voltage is showing correctly. Amperage was not specifically measured, however, no connected devices have experienced slow charging or low power issues. Screw brackets make for easy installation. Large enough to seat under several existing bolts or can fit most screws. Thin body for easy hiding in existing panel spaces. Connections are tinned copper for effective conductivity. Connection lengths are about 10", allowing for plenty of space for ease of installation. Only drawback is the connections being on same side as charging cable, preventing length of unit from being part of overall length. Charging cable stub is about 12" which allows for decent reach when installing. Utilized with dash cam which makes install as clean as factory. Ultimately great value for the cost.
Review: perfect for wiring to solar panel and charging compatible USB -C devices. - Very impressed. The first time I wired it up to a spare solar panel and charged my Ring Camera, it worked perfectly. Highly recommend. Quality construction and works as described.

## Questions & Answers

**Q: Will this work on a pi 3b?**
A: Please select the style as "Micro USB Connector"  for raspberry Pi 3.

**Q: Would this work for a 24v led strip? Would a regular pirtable phone charger power it connected with the phone charger wire?**
A: The Input Voltage of this converter is  DC 8-32V, (12V/24V is recommend);  
The Output Voltage is  DC 5V. So it can't be used as the power source for a 24V load.

**Q: can this be connected to a doorbell transformer? If so, what voltage transformer to use?**
A: Input Voltage: DC 8-32V, (12V/24V is recommend);  Output Voltage: DC 5V; Output Current: Max. 3A.
So you can use it with any load as long as the rated voltage of your load is 5V and rated current is below 3A.

**Q: Can this be used with ring base station gen 2?**
A: Does your "ring base station gen 2" come with literature that states the power requirements and at what voltage it operates?  If at 5 volts and requiring no more than 3 amps, you're okay.  I doubt that it will, however.
