What is the power output?

Enough to power the in built led bulb ...but only with a constant 10mph wind... after a couple of months in sun and a decent gust of wind the plastic composition deteriorates ...bent the blades , hitting main structure and disintegrated..... motor is normal dc motor.. played with it and it burnt out after putting 12v through it.. no idea what i could have got out of it as a generator

Can this kit be built, taken apart and re-built?

No this item can only be built once

What wattage does this unit produce? Could the bulb be replaced with a usb port to charge a power bank?

Don’t think so, model shop owner tells me just an led. Went up this road myself.
