is an input 220-240V output 9VDC 300mA safe to use on an input 100-240V 0.3A output DC6V 0.21A device? Answered

I n the manual the devise is 100-240 0.3A and my available adapter is 220-240V output 9VDC 300mA is it safe to use


9V is quite a bit more than 6V, what device do you want to plug it into? It's probably not a good idea, but it depends upon what it is. L

I think I'd say an outright no, 50% more is LOT.

not really. i don't think "50% more" would apply at this low of voltage… not for a consumer product anyway. i know you've seen those all in one adapters at radio shack… have you ever actually tested one with a multimeter? every setting between 3 and 9 volts, tested to be around 9 volts. everything above 9 was actually around 12. 1.5 tested as about 3. i used it on various devices and it worked fine without killing them. of course, your mileage may vary. …tolerances might be tighter these days.

am planning to use it on a philips cordless phone well thanks very much for the outright advice i owe u one

Aye, I should think so, but we don't know what it is yet. L
