Sorry?!? Who on here besides YOU mentioned Apple?? Nobody! So why are you bringing them up? All anybody said was any USB charger or more specifically, a micro USB, which Apple doesn't use so....What's your issue?

The Sony T series readers all charge with micro USB and work via a PC, wall or even the car!

You can plug a micro USB cable into an Apple charger and it won't work with a Sony Reader. That's why I mentioned Apple. I have a car charger (I forget the brand) has a micro USB cable and it will not charge a Sony Reader. There are a lot of USB chargers that will not work. You either have to find a compatible USB charger or wire up a cable so it works with any USB charger.

I am afraid the Apple chargers are insanely expensive, so people not having an Apple and looking for an alternate (to Sony!!!) charger will not look at Apple products in the first place. Maybe they'll look at Sony chargers, for instance those for cameras or smartwatches or smartphones or other micro-USB (charging-enabled) appliances. This is what a normal consumer will do - check with the manufacturer. Sony is also expensive.

Whether an Apple charger will work or not is per se however a good info.
Another good info is that ANY charger delivering 5V to 500-1000mA (not more) will charge any micro-USB gear (that supports charging via USB) if the cable is "prepared", by connecting both data lines via a resistor not greater than 200 ohm. A simple short will suffice.

That's the big deal.

Now, a few manufacturers use some tricks to let the charger go beyond the standard 500mA current. But this is not an issue with "older" generation devices.

There are a lot of 3rd party USB chargers that follow the Apple way. And because of that, those charger are not Sony compatible.

The Apple chargers of the new generation use a differential voltage of the data lines if they want to provide 1000mA instead of 500mA.
This is accomplished via internal resistors or resistor arrays.

Shorting the data lines in the bigger plug (USB type A) with a conductive foil of any origin (I think now of cigarettes package seal foil

) will make any stubborn, shrew Apple charger to charge any Android or any other gear that observes the USB-charging guidelines.

But as I said, the first charger one would look for is not the Apple but the Sony. If this is expensive, then a generic one will be probably the next target. Why paying 50€ when the next corner shop sells them for 3€, cable included?
