## Questions & Answers

**Q: Can this converter handle typical automotive voltages (11 to 16VDC)?**
A: Yes it’s designed to step auto volts down for cell phone usb type chargers.

**Q: Makes radio reception noise how can I eliminate the noise?**
A: Back in the day one could obtain ‘noise’ filters for installation in the output side of the power supply.  Problem is that these usually just reduced the noise level but didn’t eliminate it especially in AM radio reception.  FM is generally less affected.  Try shielded wire with shield grounded to the vehicle frame.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It works (8 Months continuous so far...)
  

*by W***. on Reviewed in the United States on May 11, 2024*

Using this to power a camera with a remote battery. Has been providing continuous power for 8 months now...

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Compact, well made, reliable so far.
  

*by F***G on Reviewed in the United States on August 3, 2020*

I used it for an outdoor automation project. I wanted to control watering both remotely and on timer. I used this to power a WeMo d1 mini, which controls a relay module. The relay module opens or closes a 12V ball valve for the water. I used an outdoor 12V transformer that plugged into an outdoor socket. It powered both the ball valve and this transformer. The ESP controller can be powered by a microusb, so this little guy was perfect. It is compact, easy to wire and works perfectly with the controller module. Can highly recommend. Will likely buy more for other automation projects, typically outdoor ones that require 12V. All open source, nothing in the cloud, cannot go obsolete when a company dies, no spying on my home network, reliable and cheap. What else do you need?

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Left or Right connector...?
  

*by T***E on Reviewed in the United States on July 12, 2020*

I wish the product description or photos would have included Left or Right 90 degree micro USB connector.My dash cam required the connector being the “other” way: I am unable to use it, therefore I cannot issue judgment on it’s function nor reliability.It generally looks well made.
