I've tried no end of car chargers but all seem to be loose and lose connection in the cigarette lighter.

 

The latest is this one I tried, a quality make - but still loose! Works OK but I have to constantly push it to one side/turn it to maintain its power.

I've even used a screwdriver to (gently) move the metal grips inside the socket out a bit but no joy.

 

Does anyone else have the same problem/solution?

Nope - my accessory socket is a nice tight fit.

I got one from Aldi which fits fine.

I use this one: http://www.kensington.com/en/sa/4472/k38119ww/powerbolt-34-dual-fast-charge-car-charger-with-micro-usb-cable#.VuL56dBvOUk

Small, tight, has two outputs (one rated at 1A and one rated at 2.4A) and performs great.
