I guess I should have mentioned why I said that. If your USB power source can handle 400 mA or more, it should work fine with the M100s. It sounds like it depends on whether your USB source can "see" such a low load. Thank you for that info.

400mA is max sustained output.  That does not mean that your computer will draw 
that much current.

I tried using my USB power cable with a 12,000 mAh power bank, but the current 
draw was to low and the power bank would not activate... pity...

Bottom line is that the USB power cable can be used with any USB device on a 
laptop/USB wall wart and the current draw should be within the USB standard 
spec.

My 102 and 200 wall warts say 6V 400 mA output.

The back of my M102 says (6V 1.2W)

Online calculator says that would be 0.2 Amps.

Which is a heck of a lot less then the power source I picked up.

That means we can use our Model T, powered bij a general-purpose USB

That means we can power our model T from our laptop ?

As I work in an IT-dept., I have an un-ending source of broken
USB-equipment (keyboards, mice, ...) I can cut off cables from.

Isn't the spec for a Model T power adapter 6V, 500 mA ? I should
check my original PS...

The adapter comes with an inline extender that swaps polarity.  Just
don't use it on our portable family of devices.

Nice cable!  What kind of adapter do you use to swap the polarity?

I know the computer guys at a hospital computer department so I
asked if they had any broken keyboards.  I got one, cut off the
cable, bought a plug at Radio Shack and soldered it on.  It's not as
nice looking as the Amazon cable but it works.  I'm sure any large
business or computer repair place would be able to give you a
keyboard or mouse cable.  However, for $10, the Amazon cable is a good deal.  I 
might buy one myself.

I'm wondering how long a USB rechargeable battery would power an
M100.  It might be something to check out.  I know a 6 volt lantern
battery will power an M100 for a week with continuous use.

I think it came from the UK and it took a fair bit of time to arrive.



It works fine with the 102/200/8300…
