Test and Tag USB Chargers

July 2014

Over the last month, there's been a substantial amount of media attention surrounding the death of a woman from a faulty USB charger.

The mother-of-two was wearing headphones at the time and it is believed the $4.95 charger sent a high voltage surge through her phone and up towards her earphones.

Test & Tag Training have discovered that there's quite a bit of confusion surrounding how to test and tag chargers, or if they should be tested at all. With the aim of clearing up the issue, we've created a short video to highlight how to test and tag USB chargers to the AS 3760 standard.

Although they're considered a low voltage appliance, it's important that USB chargers be visually inspected and electrically tested on the AC side of the transformer (the side that plugs into the wall), as this side carries 240V AC current.
