can i use the same usb charger for mac and android

Some Android devices will charge just fine from an Apple charger, some will charge slowly (regardless of amperage), and some will not charge at all.

My experience is that it does matter, but it's not so simple, because not all Android devices are the same. Of course if your device can draw 1000mA and you only use a 800mA charger then it won't charge as fast as it could but plugging it into a 1200mA charger won't make it charge any faster. One more thing to point out it is the battery charging circuit in the device being charged that determines how much current it draws, not the charger. I pulled it apart and shorted the D+ and D- pins so to matched the USB spec and it then charged the phone properly. I had a car charger that wouldn't charge the phone very fast but it was iPhone compatible. An anecdotal story I used to work for Nokia so had Nokia phones. ( )Īpple tends to do things its own way and the charger identifies itself to the device by the voltage it applies to the D+ and D- lines. However, a device being charged cannot draw more than 1.5A. Per the USB2.0 spec, a DCP shall short the D+ line to the D- line and supply 0.5 to 5.0A at 4.75V - 5.25V. For the sake of this discussion I'll just talk about wall sockets, what the USB spec refers to as a Dedicated Charging Port (DCP). How charging works depends on whether you are connected to a computer, USB hub or wall socket. You can get a copy of the offical one from usb.org. There are two USB charging standards the official one and the Apple one.
