What is the capacity of the power bank and how many device charges does it provide?

The capacity of a power bank is its energy capacity to charge gadgets. A 20,000mAh power bank provides 20,000 milliamperes in an hour. This capacity allows numerous device charges, depending on battery size and efficiency. A 20,000mAh power bank can charge a 3,000mAh smartphone 5–7 times. Larger gadgets like tablets and laptops with higher power needs will charge less. Consider the device’s battery capacity, power bank conversion efficiency, and other aspects that may affect the number of charges. Understanding a power bank’s capacity and determining how many charges it can deliver for your devices helps guarantee you have enough backup power when you need it.

Does the power bank support fast charging technologies?

Power banks must offer fast charging technologies like Power Delivery (PD) or Quick Charge (QC). These technologies speed up compatible device charging. Power Delivery (PD) is a flexible fast-charging technology that charges devices faster with higher power. PD-enabled PCs, tablets, and smartphones benefit most. Qualcomm’s proprietary fast-charging technique for Snapdragon processor devices is called Quick Charge (QC).

A power bank with PD or QC capabilities can charge devices faster and at greater voltages. This charges your gadgets faster and more efficiently, letting you top up your battery on the go. To take advantage of the power bank’s fast-charging capabilities, make sure it supports PD or QC and that your devices are compatible.
