Charging cell phones with two different adaptors

Hello Everyone: I may have posted this in the wrong place, but here goes>>

I have a new cell phone and want to know if it is ok, to use my old adaptor to charge my new phone and vise-versa? Here are the specs on the adaptors>>
Old adaptor equals "Input 120 Volts, 60Hz, 45mA
"Output DC 3.7 Volts, 350mA

New adaptor equals "Input 120 Volts 60Hz, 0.1A
"Output 3.6 Volts, 0.6A

Thanks, Tom

The difference between 3.6 and 3.7 volts is not likely significant. But the difference between 350mA and 0.6A (600mA) is significant. The 600mA charger can probably be used to charge the 350mA phone, but probably not vice versa.

Most but NOT all power packs are rated at the voltage with the required load.

I have checked some power packs labeled 12 volts DC at 500 ma. without a load the voltage was about 17 volts.
Has to do with AC peek voltage converted to DC.
That 500 ma rating was the required load to bring down the voltage to 12 volts.

People replacing power packs may burn up items by getting a higher current rating power pack.
Its best to get the exact rating when replacing a power pack. and that can be iffy.

With DC you need to match the polarity of the plugs.

GWIZ pointed out some problems that did not occur to me. So I would recommend following his advice.
