Review on 🔌 Insignia NS-AC501 AC Power Adapter - Black by Tim Ross

These are positive polarity ONLY, NO reversible plugs. Unfortunately they only fit in one direction, = + ! I was just lucky that + turned out to be what I needed for an old CD player. Unfortunately I bought 3 of these so if I need polarity I have to cut and swap the connector's wire, solder and then tape the wires. This is the ONLY way to achieve polarity, so BUYER BEWARE (which should be in big red letters in the description). Lay down and study, watch/read before you jump etc lol :-) I hope this helps others with this product (good price and shipping etc).
