Fails after a short time

I bought this item in February but due to Covid I only installed it 2 weeks ago to turn on the dash cam on my car. I drive very little, this power supply lasted just under 2 hours and is already broken. Pretty bad quality. Be careful and spend your money on the best power adapter

Pros
  • Best in its niche
Cons
  • Has flaws

Left or right port.?

I would like product descriptions or photos to include a left or right 90 degree micro USB connector. My DVR required the connection in the "other" direction: I can't use it, so I can't judge its function or reliability. In general he looks good.

Pros
  • High marks for support and durability from testers
Cons
  • I can't remember

Compact, well made and yet reliable.

Used for an outdoor automation project. I wanted to control the irrigation both remotely and by timer. I used it to power a WeMo d1 mini that controls a relay module. The relay module opens or closes the 12V water ball valve. I used an outdoor 12V transformer plugged into an outside outlet. It fed both the ball valve and this transformer. The ESP controller can be powered via micro-USB, so this little one was perfect. It's compact, easy to connect, and works great with the controller module…

Pros
  • Pretty package
Cons
  • There are disadvantages
