usb wireless charging left and right welding back can charge?

Of course, it can not be picked up casually, it must be in the prescribed order, otherwise it is not universal, and the positive and negative poles will even damage the equipment

And the color of the cable should also be unified, but some do not follow the rules, I have used a uSB plug,

One end plug is connected to 5V power supply (charging treasure), and the other end lead is connected to a booster module. Because it is not measured, the red line is positive and the black line is negative, and the module is burned out.
