Hi all,
bought an AC adapter. Asked the (clueless) vendor whether 5V meant 5.00V+-0 or something else. Vendor said, sure it's exactly 5 volts.
Now I got it and my voltmeter says 5.15V. Rumor has it that anything <5.3V is safe but the adapter wasn't too expensive and I'm afraid that loaded it could have voltage peaks. Any hints.
It's rated 2.5A @ 5V ("stabilized"). The product is called "Electronic 2.5".

Sounds grand (Electronics Engineer). I wouldn't hesitate - it's well within 5%.... and better higher than lower, to make sure it charges the battery properly...
BTW, your multimeter probably has a few percent error!

If you're measuring the voltage across a switching power supply with no load, the only voltage you'll never see is the one it's rated for. Usually it's high; I'm surprised that you saw 5.15 volts on the line, rather than 5.5 or 6. In any case, you should be just fine; my Zaurus (collie) is perfectly happy on 5-6 V.

without a load, probably just fine...whats it measure with a load?

My measurement over my previous SL5500 power adapter is 5.18V without load, so it may be Ok.
