Great way to add power where you want it in your vehicle
I bought this to provide power for my phone in my car. I use a magnetic phone holder and wanted to power it, without using a power adapter that would keep the compartment open all the time. I wired this in using an 'add-a-circuit' (http://amzn.to/1YYPzts) and hid it under the dash. Then I can use a standard cable for charging the phone, regardless of make/model, as long as it can charge via normal USB port. The 12V to 5V converter is built into the connector end, and it not very large and nicely built. Very pleased with the results.

I used this to hard-wire a dashcam into my car. Works well, it's quite small and has a long cable so that you can position the power unit in the best place. The USB output means I can change dashcams without having to resolder or rewire -- just plug in the new one. The unit itself feels well built, and puts out enough power for the dashcam. Unlike some other 12V-5V USB converters, it doesn't present itself as a PC, so there are no issues with the dashcam going into "PC connected" mode.

Tried to use this wit a camera that uses close to 15W to work and the unit shuts off. I bought three of them and all behaved the same. I believe that this unit is overrated like other ones I've bought that promise more than 2A and don't deliver.

1.0 out of 5 stars Wires are way too small. Added report - It quit working at the 6 month mark!
Reviewed in the United States on March 14, 2018

Works well. However, connecting its spindly wires to a typical gauge 12V wire is a challenge. Supplied wires are way too small for crimp connectors, so you
will likely resort to soldering. And a solder joint between wires which will be subject to movement is likely to eventually fail. Come on seller - raise the price a few cents and use decent wire.

Added at 6 months - It worked almost exactly 6 months, and suddenly died. I removed it for testing, and it was DOA in my workbench. Ther is absolutely no measurable output voltage.

Reviewed in the United States on July 24, 2018

Works properly, ample wire length.
Biggest complaint is the power wire. First the red & black power wires are tiny and extremely delicate and they are encased in a thick black outer shell. This proves difficult when striping back trying not to damage the tiny red & black wires. In addition if you are the wires are so small that crimping connectors on is a challenge.

4.0 out of 5 stars better than others as with this
Reviewed in the United States on September 2, 2016

Used with an Add a Circuit fuse tap, to create another USB power port in the car; better than others as with this, you can then plug in your own USB cord if you need a micro or mini usb output. It is running my GoSafe dash cam perfectly. Only downgraded one star as the wires could be thicker or higher amperage, but overall this is very useful.

Ordered this product so I can tap it into my cars fuse box for a hidden power supply so no cables are show. Awesome product and I got it quick. The build quality is really good too. I used a fuse tap to hook it up and it works perfect. People have complained that they are getting the right amount of amps from it but I think they might have just wired it wrong because I use it with my qi charger in the car. When I plug it to my iPhone with a lightning cable it shows the same as if I'm using an iPad charger. So yea its perfect. High speed charging.

5.0 out of 5 stars Highly recommend.
Reviewed in the United States on March 19, 2015

Product works perfectly. I wrapped the ground wire around a bolt securing the fuse box and attached the power wire to the 5V seat heater fuse. I then tucked the unit under the carpet and ran the iPhone lightning cable to it to charge my phone in the car holster. It has been in for about 6 months and I have had no issues whatsoever. Just be sure to power it to a fuse that does not have power when the car is off. This will prevent you from draining your battery if you leave something plugged in. Highly recommend.

Reviewed in Canada on August 19, 2016

This is a decent buck converter. I tested this product with a programmeable DC load at 1 A, constant-current for over an hour. It provided this current at approximately 5.02V and was drawing 0.45A on the 12V side. The unit was only warm to the touch. I pushed it to 2A for a few minutes and the voltage dropped to 4.99. The specs don't indicate if the max current is peak or continuous, so thats as far as I went. Voltage input was 12.8V for the tests.
