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.
