Why do some AC cell phone chargers work on 74 volts DC and others do not?

While it is true that some AC cell phone chargers are known to work on 74 volts AC, it is not recommended. We have received reports from many users that "Travel Chargers" work fine to charge their phone. We have also received reports of damaged batteries and cell phones by these chargers plugged directly into 74 volts DC.

The design of these chargers are for use with AC. Chargers that contain a transformer will usually not function with 74 volts DC, and have been known to "smoke" when connected. There is another website at www.fogchart.com that has more extensive information on this subject.

They can give you a good idea if your device will function on 74 volts DC. Click HERE to take a look: http://URL1/74VDC. Htm Jerry also has some other great information available there.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
