This is the third DROK item I've purchased and they are all useful little circuits and good value too. Well worth the dollars.
General construction is nice, however, the single unit I received has a cold solder joint on the feedback resistor. Thus, the unit is dead on arrival. Having something so broken, especially on the feedback path which can potential cause high voltage to flow to the load, is just unacceptable quality control. Thus, test new unit out carefully before connect to anything important.
It works perfectly, and after running a long USB cable from the fuse box under the carpet, up behind the sidewall on the passenger side, up through the pillar next to the windshield, insider the front edge of the headliner and out right in the center of the windshield just in front of my rear-view mirror, my dash cam now gets perfect power with no visible wiring.
This does require just a little bit of electrical knowlege, and a soldering iron, but the whole process took me 1 evening to complete.
I'll add some pictures of some of the steps - taken with a macro lens that distorts some parts of the images. Don't worry, the board actually does have nice straight edges.
There is a chance my cheap monitor is wrong. When useing a apple 2amp charger I only see 1.5 amps. But at lest that can give you a idea.
Overview pro: it's a good size. Love the read out for source voltage, seems close.
Cons: did not matter what voltage I was useing this thing runs HOT! And it looks very hard to add cooling. During testing I had a little fan standing by that I used for cooling. Not a lot of cfm (15-35?) was still warm but not scary hot like before. Maybe the chip will hold up to it? But I don't like my stuff running hot
I wired this into 12V switched (keyed) and it'll turn on/off my dash cam with my key.
... works great thus far. I'll update if it causes any issues or problems down the road.
Simple step install;
- find 12V keyed, and extend via small gauge wiring to overhead (behind headliner)
- find ground, and also extend to overhead
- solder 12V and ground to appropriate solder spots on USB power supply
- cover entire assembly in heat shrink (I did two coverings for best insulation)
- connect USB to mini USB cord, and plug into dash cam.
- Presto! Ta-Da! Done! Easy-Peasy!
