Review on 🔌 RV PowerMax PM3-75 110V AC to 12V DC Converter Charger - 75 Amp by Eric Longoria

Unit came via FedX, PSU came in 2 boxes with seal, packaging was fine. power indicator. I measured zero voltage at the terminals and checked all 3 40 amp fuses that are not blown. I noticed a black dot on the red connector on the power supply. (See photo) An indication of a possible short circuit and the use of terminal screws. Most notable was the date code on the 2001 box. (See photo) Getting an item over 19 for this price is not acceptable. (Serial numbers match) My guess is that the unit was returned and nobody bothered to test it before it was shipped as a new product. I am returning the device for a full refund.
