The Tripplikit USB Charger Tester uses a micro-controller to draw a controlled amount of current from your charger. I gradually ramps up this current while, at the same time, monitoring the charger voltage.

Once the tester is drawing the maximum current that the charger can supply, the charger’s output voltage will start to drop. At this point the USB Charger Tester will reduce the current drawn by 15% and “soak test” the charger for a further 40 seconds.

The You Tube video shows the USB Charger Tester in action.
