Car Hard Wire Charger, 12V to 5V Dual USB Female Port Charging Cable Direct Link Hard Wired Step Down Converter Power Supply for Dash Camera Car DVR GPS

Upon inserting the male end of USB ports (I tried several) two things happened - The two do not completely engage. They easily fall apart. I had planed to put this under my dash and hook up my GPS and dash cam to them. No confidence in it now and O have not even tried to power it up. Whats the point? Could have been a five start if it just would have held the connectors together securely. I may try using shrink tubing around it but that does not excuse poor fit.

Everything as advertised. I simply tapped the hot (and ground) on the map light in my car to add a USB for dash cam power in the headliner. Less than 15 minutes to get everything done. Very happy.

Small size allows for installation almost anywhere you need. However, it would have been better if the incoming power wires were a little longer

Works well. Should include t-tap for this price

No instructions shown which wire is Positive! Shorted out my IPOD.

Easy to install and works great

I wanted to add some extra usbs in my vehicle for electronics I take when I travel. This was very easy to install and hide

I purchased this for my Bluetooth adapter,needed a 5V power source. Also i used if to power the dash cam. Install was easy,you need to tap in to 12v wire or your car,i did it on the cigarette lighter wires. Bluetooth adapter and camera work fine,no issues.

Needed a way to connect 5V light strings to a 12V AGM battery for camping and this is an inexpensive and easy way to accomplish the task without having to build your own converter.

Great
