I bought a plastic storage box with a lid for my son to put all his wires in - they seem to multiply round the house with no help!
Instead of looking properly for a particular wire that he knows he has already, he orders another one - and so it goes on!
I have several rechargeable things - lawnmower, hedge trimmer, strimmer, vacuum cleaner, plus mobile phone, toothbrush, so all those chargers are in one box and labelled after I got fed up wondering why my strimmer wouldn't work after it had been "charging" for hours !
Whoever makes a one size fits all charger at some point, preferably without me having to replace what I already have, will deserve a medal and my everlasting thanks!!!
