A long electrical lead (South Reading RG2)

Hello - in the interests of recycling and saving my pocket - l am looking for a long lead that l can convert to a charging lead to be plugged in my garage. Something like a lead from a gardening implement - like a lawn mower…Or maybe a long lead from a hoover - you get my drift… l can help out by taking away the redundant item and taking it to the tip - as l have stuff to take myself…. Even better an unused extension lead lurking around that doesn’t get used would be very helpful! Many thanks for reading and l hope you can help me….
