I study your complete post but nevertheless am confused.....will these chargers hurt or problems my IPhone5s.
In India, I just plug US chargers into 220V (immediately after diligently reading the label to be sure it'll go ahead and take voltage). I make use of a Kensington travel adapter, which converts the plug structure, not the voltage.
I just bought a $two counterfeit that appears accurately identical to the authentic iPhone charger proven in the posting...
This counterfeit charger has much sounds during the output which i had to double the size over the remaining to receive it to fit. Observe the incredibly substantial spikes inside the output (yellow).

You feel extremely worried about the voltage of the Apple adapters. The USB spec allows the availability voltage to change in between four.4V and 5.25V, so a USB system has in order to use these voltages. Hence the iPad electric power offer drooping right down to four.4V is not a dilemma.
The higher remaining issue on the curve demonstrates the voltage made by the charger when there is not any load on the charger. Since the load boosts, the charger is alleged to hold a constant voltage and raise the existing (i.
I could not locate any UL safety acceptance on this charger, but I did discover a report of one catching fireplace. Motorola
