Is a 20,000 mAh power bank too big?

In today's connected world, smartphones, tablets, laptop computers, and a variety of other devices have become an essential part of our lives, so you need a reliable way to charge them on the go. A 20,000 mAh power bank is one of the options that are becoming popular. The key question: Is it too bulky, or the perfect balance of portability and endurance? This depends on your individual needs and lifestyle, as well as your usage of your devices.

Comprehending the Capacity of Power Banks

What is mAh?

Milliampere-hours (mAh) is the measure of the total energy of a battery. It is like using them as a gas tank for your charger. The bigger the mAh, the bigger the power bank you will have and the greater the number of times you will be able to charge your gadgets.

But the label number does not represent the exact power you are going to have. There is some energy wastage when charging, due to the variance in voltages and the power bank's internal circuitry. Consequently, the actual capacity ever used is normally less than 60-70 percent of the marked label capacity. An average 20,000 mAh power bank will provide approximately 12,000–14,000 mAh of power.

Watt-Hour Conversion

A measurement of power banks in airlines is watt-hours (Wh). The power bank with 3.7 V at 20,000 Ah is approximately 74 Wh, which is well within the limits of 100 Wh that most airlines impose on carry-on baggage.

What is the duration of a 20,000 mAh power bank?

You can charge several devices with the power bank, and the time that the power bank lasts will depend on how many gadgets and batteries you are charging. Here is what usually happens:

Smartphone Charging

A modern phone has a battery with a capacity between 3,000 and 6,000 mAh. For a typical 4,000 mAh phone battery, expect 3–4 full charges (after efficiency losses)

Tablet Charging

Tablets tend to have increasing battery capacities, approximately 7,000-10,000 mAh. Most of the tablets will benefit from up to two full charges on the power bank.

Other Devices

• Wearables (smartwatches, earbuds): They contain very small batteries, typically 200-500 mAh, which means that the power bank will be able to charge them several times.
• Gaming gadgets: The power bank can handle the charge of several full charges on portable consoles and controllers.
• Small laptops: Small laptops can be charged partially by the power bank, provided they have a USB-C Power Delivery port, although this availability is a matter of compatibility with the power bank.

Charge in standby mode to save power

One should be educated on the difference between charging in an off or standby position of a device and charging a device that's powered on and in use. The charging of an idle gadget conserves energy. However, when you plug in a device when it is on and is working, the power bank will run out more quickly since the device is consuming power at all times.

Which Devices Can a 20,000 mAh Power Bank Charge?

A 20,000 mAh power bank has an incredible range of device compatibility:

The only restriction here is with high-wattage devices that have a draw that is greater than what the power bank can supply via the charge ports.

Advantages and Disadvantages of 20,000 mAh Power Banks

Pros

• Lasting Power Supply: This power bank has the ability to charge a number of devices on numerous occasions. It is suitable for long journeys, camping, and emergencies.
• Peace of Mind! You will not be worried about running out of battery since you have plenty of reserve power when out of a charger.
• Value for Heavy Uses: In case you use your mobile phone or tablet frequently, the 20,000 mAh size gives more value than the smaller ones.
• Multi-Device Charging: You are able to charge multiple devices simultaneously, and this is very useful in cases of families or people who have a lot of gadgets.

Cons

• Size and Weights: They typically have a weight of 350-500 grams (12-18 ounces), and they are larger in size than smaller banks. It has been described by some as being like two phones stacked.
• Recharge Time: They require 6-10 hours to be fully charged due to the power they have. That takes more planning.
• Portability: They have increased portability, but they are not pocket-sized. A bag, backpack, or briefcase will be required to transport them.
• Too Much Capacity: When you only need a top-up now and then, then maybe you need more than you think in the big capacity.

When Is 20000 mAh Too Much—Or Just Right?

Ideal Scenarios for 20,000 mAh

• Travel and Tourism: In the case of trips taking more than a few days, long flights, or going to locations with inaccessible plugs or those with plugs that do not fit. The large storage size will ensure that your phone, tablet, or camera performs to the last bit for you.
• Camping and Outdoor Activities: Camping when you are off the grid. The bank provides sufficient power for GPS, phones, radios, and games.
• Professional Use: It will be handy to people who rely on devices to work, photographers, vloggers, and field technicians.
• Multi-Device Households: Families or friends who travel with them that require the need to charge a high number of devices simultaneously.
• Emergency Preparedness: During storms, earthquakes, or any power failure, having a bank is going to provide radios, phones, and lights.

When It Might Be Excessive

• Daily Commuting: In case you have to drive or walk to work or to school, and you can charge there.
• Light Device Usage: In case you do not use your phone or tablet so frequently, you can plug it in frequently.
• Weight-Sensitive: Hiking, running, or sporting at all, where weight is of concern.

Comparison to other Capacities.

• 10,000 mAh Power Banks: Portable (180-250 g). Good to use on a daily basis and in case of an emergency. Most suitable for those who desire lightweight in the long term.
• 30,000 mAh Power Banks: Voluminous and bulky, can exceed airline restrictions (more than 100 Wh). Better for persons wishing to have a large battery or an extended off-grid journey.
