Comment on Not buying a shaver from Philips again..

I can tell you for certain, I measured my plug phiips (foil and ‘one’) and they are both 14VDC. So short answer is that the plug charger would blow up the usb trimmer you have (which is 5VDC).
The reason I know this and measured them, was because I wasnt sure the two plug chargers were the same, and I didnt want to blow up my philips one.

Also the charger is required to show its voltage and amperage output ratings.

This is true, but something about being an Electronics Engineer makes you want to check. (I didn’t even trust Philips to get it right, but they did.)
I didn’t go into detail, but simple Dashed/Solid line doesn’t tell you the whole story. Those simple wall warts are not fancy switch mode, or even old school rectified. I measured 14VDC unloaded, which I can probably guestimate in experience, to be a 9VDC loaded reading.
The actual reading on wallwarts are generally untrustworthy, unless its a thing from Samsung or apple, where the circuitry are what you would expect (switched etc).
