Quality

In combination with having it connected to my house battery i got the green led which indicates everything works fine and it does charge 🙂

Pretty straightforward install and good vehicle charge system protection for a solar/lithium set up.

Fires up & begins charging within 5sec of turning on.

Started the engine and the battery said it was charging at 20 amps.

Price

Don't burn your truck or rv down because you want to save $5.

That is a higher draw/more loss than i was hoping for, but it is cheap so you get what you pay for.

Competitiveness

I bought another brand's dc to dc charger and purchased the renogy one after the other brand did not function correctly.
