Product Information

Charging Speed: Different power banks vary in terms of charging speed. Look for power banks that offer fast charging capabilities to efficiently charge your devices without any delays. The energy storage capacity of power banks is measured in mAh (milliampere / hour). When they first came about, most power banks were capable of storing under 10000mAh, whereas these days most power banks hold closer to 20000mAh.

If you want to do the conversion by hand, here’s the formula behind our Wh calculator: Wh = mAh × V / 1000 We know that the more energy a power bank stores, the more times it can charge a device. How do you know the amount of energy a power bank contains? We measure a battery's electrical capacity by its mAh (milliamp Hours). So if you want to get a device that has a real capacity of 100000mAh, then you should buy one with an advertised capacity of at least 1250000mAh. What does the future hold? Number of Ports: Assess the number and types of charging ports available in the power bank. Multiple USB ports or other connector types ensure you can charge multiple devices simultaneously.

mAh to Wh conversion calculator

mAH does not indicate the power capacity of a battery as two batteries with the same mAh value may deliver a different amount of energy. We must consider another variable, the Volt, for calculating the power capacity denoted by Wh. Volt refers to the difference in the electric potential between the positive and negative terminals of a battery. It is the force required to overcome the resistance and move the electrons to make the battery work. How many volts do power banks have?

However, this product does come at a premium price. It is also far heavier and more bulky than a slimline power bank and therefore is less convenient and easy to carry about. mAh stands for milliamp-hourand it’s the unit of electric charge and commonly used to express the capacity of the small batteries. mAh specify the total amount of charge passing through a point in a certain period of time. A battery with a higher mAh value will power a system for a longer time. It is typically used to specify and describe the total amount of energy retained by a battery. Size and Weight: Consider the size and weight of the power bank, especially if you frequently travel or carry it with you. Opt for a model that is lightweight and compact for hassle-free portability.Additional Features: Some power banks include extra features such as built-in flashlights, wireless charging capabilities, or even the ability to jump-start a car battery. Consider any additional features that may be useful to you.
