So Christmas has come and gone, bringing with it the usual influx of new
low-voltage power supplies for assorted gadgets and gizmos.
Unbelievable. When are these things going to get at least half-way
standardised to avoid having to have so many lying around?

Anyway...

One new incoming gadget was an LG mobile phone. As it happens, we
already have an LG charger in the house from another (now stolen) model:
they look physically identical and have the same proprietary jackplugs.

The old wallwart says it puts out 4.8V / 0.9A; but the new one is 5.1V /
0.7A (ie higher volts but lower current).

Can we use the old charger on the new phone without worry, or should I
bin it urgently to avoid an 'accident'?

Thanks
David
