Getting fed up replacing the AA batteries in my wall clocks. Is there any way I can utalize a mobile phone charger to run them off mains. Need some voltage reducing device obviously, but what ?

How often do you replace your batteries??
We've 2 wall clocks and I reckon they last well over 12 months.
As Tilly suggests, try using rechargeable batteries, but go for one with a high mAh. The higher the mAh, the longer the battery will last, so you won't need to remove them (so you can recharge them) as often as one with a lower mAh.

Strange because my wall clock batteries last for years....and the clocks are radio-controlled (so use a bit more power).
Actually, using rechargeables in a clock isn't a good idea....they are better at medium/high drain devices for a shorter time and not very low drain devices for a very long time. Also, rechargeables in a clock won't last as long as good quality alkalines. Not to mention the economics of rechargeable vs alkaline...a very pricey clock battery!

Can't say I've tried it myself but maybe this would work with a standard power supply, from Maplins or some similar store ?
