Another example: I have an electric razor which takes up to 1A at 5V (DC). Sounds perfect for a USB charger, right? It does not have a USB connector but a proprietary thing. The one with the USB connector is labelled travel razor and costs 20 € more. It's outrageous because most likely the USB connector is even cheaper than the other because it is produced in much higher numbers. If the charger dies before the machine itself, I will modify the cable and see how well that works.
