Guide to Power Bank Battery Capacity

 

Milliampere-Hour Rating

 

Any portable charger's battery capacity is expressed in milliampere-hours, or mAh. It is the unit of measure used by tech manufacturers to define the capacity of the power banks that they make. When a power bank is rated at a specific mAh, it means that it can recharge your devices a particular number of times through this number. For example, a 5,000 mAh battery of a phone can be recharged four times by a 20,000 mAh power bank. This means that a higher battery capacity of the power bank will allow more device recharges on a single power bank charge. A 100,000 mAh power bank can recharge a number of devices without needing to replenish the battery of the charger.

 

Power Bank Weight

 

Technically, a power bank that has a bigger capacity will be heavier compared to a device that has a lower one. This is because of the number of batteries that must be kept inside the power bank so that it can transfer the stored power to the devices that you use every day. A 50,000 mAh power bank will be heavier compared to a 5,000 mAh power bank. This will also help you decide on what capacity you actually need without the added burden of carrying it around because of its weight. What is the actual capacity that can sustain your devices? How long are you out of the house or office before you are able to recharge your phones, tablets, or laptops?

 

Power Bank Dimension

 

The power bank's capacity will also have an impact on its dimensions. When compared to a device with a lower rating, a power bank with a higher milliampere-hour rating ought to be larger. This means that the higher capacity will give you more power but will also need more space in your bag because of its dimensions. Some power banks from reputable manufacturers have continuously innovated their products in order to provide their consumers with a small power bank, yet with a bigger capacity compared to their contemporaries. You can get smaller dimensions on power banks with higher power ratings without any compromise on performance and quality.
