What is mAh In A Power Bank?

Similar to the diversity of cellphones available, these devices come in a wide range of sizes, forms, and power capacities.

When investigating these units, the phrase you encounter the most frequently is mAh. The term “milliampere hour” is an acronym that represents the electrical capacity of tiny batteries. Because “ampere” is always denoted with a capital A in accordance with the International System of Units, the A is capitalized. The mAh rating merely indicates the capability for power flow over time.

In Other Words:

The unit used to describe how long (per hour) a power bank can deliver a specific quantity of current is known as milliamps per hour (mAh) (mA). The output of a typical adaptor for a smartphone is 1000 mA. Your smartphone carries 1000 mAh when you charge it for one hour. You may then charge your smartphone 10 times with a power bank that has a 10,000 mAh capacity.

What Does mAh Mean In Batteries (Battery Capacity)

A Typical Misunderstanding About mAh

The capacity of a battery is often expressed in milliampere-hours (mAh). One widespread fallacy is that we can calculate how many times we can use this power bank to charge the smartphone or tablet by simply dividing the capacity of the battery by the capacity of the device. However, that algorithm is incorrect.

Energy And Capacity Are Two Distinct Ideas.

Simply explained, Watt Hour (Wh) is a measure of electric energy, whereas Ampere-Hour (mAh) is a measure of electric charge, which indicates the capacity of a battery.

Ampere-Hour x Voltage = Watt-Hour

A charger with a size of 10400mAh may deliver a total charge of 10400mAh at a particular voltage. A lithium-ion battery exchanges the majority of its charge at a voltage of about 3.7V. 

In theory, a 10400mAh battery has a total energy of 10400mAh x 3.7V = 38480mWh, or about 38Wh.

Significant Variations In Power Banks.

The capacity of each power bank determines how frequently it may be used to recharge your electrical devices. Therefore, a power bank with a higher capacity (mAh) can recharge your gadgets more frequently than one with a lower capacity. Some electrical gadgets require a greater capacity charger because they use more electricity. In contrast to other power banks, a 40,000 mAh power bank can be used to charge your Macbook or laptop.

How Frequently Can I Use A Power Bank To Charge My Phone?

The capacity of the battery in a power bank determines how many times you can recharge your smartphone, tablet, or laptop using it. By dividing the capacity of the power bank by the capacity of your electrical device, you can quickly determine how frequently you can charge your gadgets with a power bank. For instance: A smartphone has a 4000 mAh capacity, and a 12000 mAh power bank. Afterward, you can divide 12000 mAh by 4000 mAh, and the result is 3.

Marking Capacity Versus Real Capacity

Between a power bank’s actual capacity and its stated capacity, there is a noticeable discrepancy. A power bank with a capacity of 10,000mAh won’t actually transmit 10,000mAh to another device, but significantly less. About 80–85 percent of the marking capability will be transferred.

The majority of power banks include lithium batteries, which typically have a voltage of 3.7V. A device is charged by a power bank using a USB-C port, which has a 5.1V voltage. Instead of using the 5.1V that we utilize, manufacturers base their calculations on the 3.7V amount. The actual capacity is thus substantially lower.

You must first convert from mAh to mWh and then back to mAh in order to determine the actual capacity (with the 5V). Thus, 10000mAh times 3.7V (the lithium voltage) is 37,000mWh, and 5.1V (the USB-C voltage) equals 7,555mAh. The power bank loses 10% of its power when converting these numbers. Therefore, a 10000mAh power bank has just 6,528mAh.

How To Measure The Capacity of A Power Bank

But Which Type of Portable Charger Suits You The Best?

We advise you to make an early decision on the power bank’s intended use and power user type. Will you sometimes top off your phone with the extra energy (low use), or will you need a power source to set up a remote office so you can get ahead on some work while on vacation (heavy use)? You can evaluate your possibilities after you are aware of your use cases.

Heavy

The best option if you require a greater power source with a longer runtime is a portable power bank with a large mAh, like 40,000 mAh. You do run the risk of losing portability with this choice, so consider how you will keep it for easy access.

There are several different types of portable battery banks available today that are small enough to fit in a backpack and provide multiple power sources, including AC outlets and USB charging connectors.

Light

A smaller, more portable power supply would be ideal for you if you only sometimes boost power. You’ll get the most use out of power banks with capacities between 5000 and 2000 mAh, but keep in mind that smaller devices are likely to have fewer power options.

Ways To Estimate How Many mAh You Require

There are 4 ways to estimate how many mAh you require:

• 1. Consider the intended audience. How much are you prepared to shell out for them? What kind of mAh would they require?

• 2. Consider the sell, exchange, or giveaway’s intended use to decide the size and price that will best accomplish the task.

• 3. Determine the mAh values of the devices you intend to charge with your power bank (the table below provides this data on some of the most popular gadgets in use today).

• 4. Calculate how many charging cycles you want your power bank to provide using the information from step 1. You will have a total of nine charging cycles, for instance, if your power bank has a mAh value of 9,000 and the device you need to charge has a mAh capacity of 1,000.
