Cooking my IPAQ 3870

I recently purchased a sync & charge usb cable and a cigarette lighter adaptor for this usb cale. Also, there is a mains transformer which is rated at output of 12 volts, 400ma, 3.6watts max. I know the Ipaq is only a 5volt unit. I contacted the supplier who said the 12 volt mains charger is ok for this unit. My question is WILL IT COOK MY 3870? Seems logical to me that the charger should be rated at around 5 volts. Any help before I start cooking would be much appreciated. Rolling Eyes

yes, a 12V output will cook your PDA, and pretty quickly. It is very irresponsible of your supplier to state such a crap.

You will need to clarify what the 12v refers to, if its is the Input then 12v for a car charger would be correct but it does need to be 5v output. I suspect these are becoming confused.

Obviously a mains charger will not be 12v Input, it will be 220 - 240v. There should be a label on the charger indicating the input and output voltages.

As Lutz has said though, you need to be 100% sure before using either, if they are outputting 12v you will destroy your iPAQ.

The thing is, if the manufacturer is that slap dash about labelling the voltages, would you really want to trust it long term to power your PDA?
