If you use both outputs to charge two devices, the required charging time will increase.

Please take into account that charging your Extra Battery and other device simultaneously may result in a reduction of the battery life.


Can I use any USB cable?

Your Extra Battery has a built-in cable to connect microUSB devices. Another option is to use the USB Type A output to connect any other compatible cable that you have already at home.
For devices with special outputs like the ones from Apple, you can use the original cable that belongs to them since you can connect one end of the cable to the USB type A outlet of your Extra Battery.

Which output rating will use my Extra Battery 10000 to charge my devices (smartphone, MP3…)?

The output rating will depend on the battery capacity of the device that you want to charge.
Smartphones, for instance, usually have an approximate charging capacity that goes from 1400 to 2200 mAh depending on the model.

When your Extra Battery is fully charged (100%), it has a capacity of 10000 mAh. Nevertheless, energy is lost in the charging process and there are other factors like the use that you make of your phone and its settings because it can keep consuming energy, especially if the device, Wi-Fi, 4G, etc, are on.

How much time will it take to charge a device?

It will depend on the battery capacity of your device. You can choose between the 1000 mA or the 2100 mA output, the same capacity that most original chargers on the market offer. Therefore, the charging time will be more or less the same. If you use both outputs at the same time, it will take more time to charge.

How much time will it take to charge my Extra Battery?

It will depend on the output power of the source that you use to charge it. If you use a computer, it will take longer than if you use a smartphone or tablet charger since the last mentioned have been conceived to charge devices. The charging process may take between 4 and 10 hours.
