USB Battery Charger

USB Battery Charger

USB devices that need more power than this are called high power devices (instead of low power).  The maximum load that is requested for USB2.0 is 500mA and USB3.0 is 900mA.

The USB Battery Charger Specification gives optional new power modes. A host or hub port that supports charging can only supply up to 1.5 A when communicating at low speed or full speed, or a maximum of 900 mA when communicating at high speed, and as much current as the connector will safely handle when no communication is taking place.

Most people use USB charger for multiple devices not knowing if it is good or bad this will show the required answer. While you are thinking that all mini USB cables are of equal size, just because a charger fits your device doesn’t really means you should use it.

As there are different types of smartphones and tablets, these also have different voltage required for successful charging; when there are too many volts from the charger the gadget fries which may cause a fault to the phones charging port which will be too few and the device will take forever to charge. With this point, it is noted that it is not right to share USB chargers.

Most of us out of lack of information charge our phone with USB connected to laptops well it is not safe because it exposes battery chemicals to unsafe, secure and fast charges, lowing the batteries voltage and damaging the phone’s cell.
