Need to know voltage and polarity of ZIP external power supply

[InTheSand]

Hi,

Have just taken a look at mine (had to follow a dusty lead through a nice tangle at the back of my computer desk!) and the power supply itself says:

Model: APS57ER-210
Output: 5V 1A

This is the UK version.

I've checked the output with a multimeter and it's a positive tip.

Regards,
