When you need power for your gadgets and you need it fast, skip the USB port on your computer and switch to a wall charger for a boost; read on to see why.
Specifications for USB ports have changed over the years and the port on your computer likely doesn’t put out enough juice to charge your portable electronics as fast as a wall charger could. Extreme Tech explains:
There is a huge variance, then, between normal USB 2.0 ports rated at 500mA and dedicated charging ports which range all the way up to 2100mA. This leads to a rather important question: If you take a smartphone which came with a 900mA wall charger, and plug it into a 2100mA iPad charger, will it blow up?
In short, no: You can plug any USB device into any USB cable and into any USB port, and nothing will blow up — and in fact, using a more powerful charger should speed up battery charging.
