 3rd, the charger is alleged to provide a relentless voltage. A lousy layout may cause the voltage to sag because the load will increase.

I connect with this charger the Samsung rectangular charger, to tell apart it through the Samsung dice charger. Samsung cube
Thanks for your feedback. LeMadChef: 12V converters can be attention-grabbing to examine; Maybe a potential report.
I would love some clarification about the "Indicated charger form" check. Exactly what is utilised to be a load? An iDevice? A resistor? Different machine based on the charger?
I could not discover any UL security approval on this charger, but I did discover a report of one catching fire. Motorola
