Power Banks with 2 outputs
Powerbanks with at least two outputs allow you to charge more than one device at a time. This option requires sufficient power bank capacity. Power banks with a capacity of more than 15,000 mAh can be considered optimal for charging two devices at the same time.
However, you can also charge two devices at once with a low battery capacity from a power bank with a capacity of 5,000 mAh, for example, two smartwatches or a watch and wireless headphones.
In the package you will usually find a power bank and a charging cable. An additional cable for charging your device will need to be purchased depending on which connector you need. The two charging outputs on the power bank are most often traditional USB outputs, in some cases it may be a combination of a USB connector with USB-C or Lightning, or even micro USB on some older models. You may therefore find USB/USB-C, USB/Lightning, USB-C/USB-C and other cables useful.
