Necessity if you like warm rooms

There was no mistake with the title. I really mean it. I have designed and made radiator fans so my home warms up super quickly, stays toasty and keeps my heating bills down. I didn't want to replace one bill with another do designed the usb fans to run off power banks and not the mains. 

These power banks are brilliant they last all night and they charged quickly too 

Light weight so can be used to charge your phone on the go or fuck into a space to discreetly run usb lights etc. 

I have 4 from this company each sturdily built and quality. 

Highly recommended
