What are the dimensions of the unit?

A little bigger than s cigarette pack.

is there a "continuous mode" (no forced shutdown after 10,15, or 30 minutes)?

If you change the time settings, you can have it running until it run out of charge. So, yes there is

asked if battery can be replaced you said no-how long does the lithium battery last then?

Mine is about 1-1/2 years old and only has 1/2 the power strength it used to.

My unit came with a white usb charger... has anyone else got a white charger too? could it be something wrong with my charger adapter?

I don't think they color-match the unit and the charger.
