Labelling Requirements for USB-Powered Device

Mark Meer

Trusted Information Resource
We are developing a battery-powered medical device, intended to be charged via USB connection.

Does anyone know if there are any labelling requirements that I need to consider?

Previously, our battery-powered devices have been charged via a dedicated supply-mains charger, so we've had to etch the input specifications on the charger.

However, with USB, I'm not sure how this applies, as ultimately the USB connection will be supplied by the user (e.g. via their computer, or existing mains adaptor like from a cell phone). Is it sufficient (or even necessary) just to have the USB symbol next to the input?

Any advice/input much appreciated...

USB = Universal Serial Bus

I bet it is governed by very detailed published standard specifications...

My common sense says that as long as your device is in compliance with those universal (standard) specifications, including labelling (eg USB symbol, if it is actually part of the standard - I wouldn't know), you should be fine. You could also add in your labelling (eg user manual etc.) that the device is compatible with any <published standard>-compliant USB outlet.
