Dumb easy question about MK902ii power plug

[sql.sith]

I know that there's no such thing as a stupid question, but I have one.

For whatever reason, I have decided to put a RikoMagic MK902ii in my car. To do this, I need to get a power inverter or other DC power source. I cannot find, anywhere, a definitive statement on the size of the DC plug required for this box. Does anyone know? Those barrel plugs come in a zillion sizes, so I'm not sure what size to get. I'm guessing the outside diameter is 5mm or 5.5mm and the inside is 2.1mm or 2.5mm? But it's impossible to tell from the pictures online, and the specs never say. Does anyone know the size of the barrel plug for the MK902ii?

Hi,
I think you can also power it using the USB host port if you want to.

Really? That would make my life much simpler. I have the unit now (still don't know how to measure the plug size for sure) but I'll have to check if it takes power via USB. Thanks for suggesting this!

Thanks for the reply! I have the unit now, so all I have to do to test this is find a cable. There's also the suggestion below that the unit may take power from USB, in which case I already have a 3A USB car charger that I can use.

Enter the following into search on **** and it will give you the cable required, if the dimensions provided earlier are correct: 'USB to DC5.5mm 2.1mm Power Charger Cable'
