I'm hunting forward to a vehicle charger Model of the comparison. many thanks for the great thorough info!

The Motorola charger has the bottom listed electricity output, 850mA. The back of it's a holographic sticker (similar to a bank card), which may push back counterfeiters, Though It is not likely for anybody to counterfeit this charger.

I concur that noisy, spiky output may result in instability and undesirable conduct in sensitive electronics, like the aforementioned contact-screens, when charging... but a battery is not as picky!
