      should do. They are adjustable via a potentiometer. Iam using the latter one for a Pi Zero but the 3A are enough to power a Pi3 easily. You should check aliexpress.com since most of the low priced parts already come from China. They will be even cheaper and are the very same product.

              Sure it works. I just proposed the other one because it’s very compact and I thought that was important. Use the once you already have to save costs as long as it suits you. It’s powerful enough if those values are correct.

              Especially those black power bricks can be of very bad quality. Run your mirror setup for a few hours and check that the power supply isn’t getting too hot.

                My problem with it was that I didn’t want to have the brick of it out side the case. Or 3 foot of wire looped inside but I’ll have to cut it to add the step down anyway. So I may as well try it that way first. But I also didn’t know if it was big enough for both To run off of.

                    @The-Bean Whats the buck down converter? I guess the pi is just a to big load for it

                    Never expect those china buck down converters to achieve more than 50% of what they say they will do (especially without additional cooler)

                      @The-Bean you might want to try with a additional cooler on the converter since the pi is not constantly pulling 2A, so it might work
