Cable test ends in flames

This was a 5A current test on an excruciatingly thin copper coated steel cable supplied with a dangerous product purchased from eBay. The product was notable for putting out full mains voltage on a USB phone charging port, and using non rechargeable batteries with a very basic charging circuit that could make them explode.

Here's the video of the horrific product this was from:-

If you really must buy cheap products from eBay and other equally safety-complacent platforms, then I recommend at the very least disposing of the supplied cables in a safe manner, and replacing them with cables purchased from reputable suppliers that comply with local safety regulations.

On a typical power circuit this cable would have been a huge hazard due to its high resistance and ultra-thin wire. It could literally have set fire to furnishings in the event of a product fault, or even just using it with a higher power appliance. Sadly there are many equally bad cables with some using extra thick plastic to give the impression of having bigger conductors.

The fire extinguisher I used is a Firestop aerosol unit that is a convenient size for little bench incidents.
