hello everyone this is a test of the banggood 20 amp 1200 watt dc-to-dc buck up converter and before I start complaining about it I wanted to just register that it's actually a very good unit I'm very pleased with it the complaints are very minimal given the cost and the first thing that I wanted to say was how it arrived it did arrive in two weeks so relatively quick however banggood shipped it in this bag which was the unit was inside this dusty bag with like had been sitting on the shelf for a while and it was only wrapped in this and so of course it took quite a beating coming here one of the capacitors was nicked and bent over and I gently pushed it back and it appears not to have affected it so the connectors were still intact so that was the one thing that I was surprised at how we shipped banggood please ship these in a box please ok so now into the talking about the unit itself
