Why Watt-Hours (Wh) Are Important When Buying A Power Bank

By Pankaj Mirchandani – Watt-hours, often abbreviated as Wh, are a measure of energy capacity in a power bank. They indicate how much energy a power bank can store and subsequently deliver to charge devices such as smartphones, tablets, and even laptops. The higher the watt-hours, the more energy the power bank can store and the more charges it can provide to your devices.

Significance of Watt-Hours in a Power Bank

When choosing a power bank, it’s essential to consider the watt-hours it offers. A high-capacity power bank with a large watt-hour rating will be able to charge your device multiple times before needing to be recharged. This is especially important for those who travel frequently or spend a lot of time away from a power outlet. A high-watt-hour power bank can be a lifesaver for those who rely on their devices for work or entertainment.

One example of a high-capacity power bank is a 100W powerbank, which typically offers a higher watt-hour rating than a regular power bank. These power banks are designed to provide enough power to charge laptops and other large devices, making them perfect for business travelers or students who need to work on the go. Laptop power banks usually have a capacity of 60-100 watt-hours, which is enough to charge a laptop several times before needing to be recharged. Check out the 94.7Wh & 88.8Wh Juice-Up Powerbanks from UltraProlink.

Another important factor to consider when choosing a power bank is the device’s battery capacity, measured in milliampere-hours (mAh). The device’s battery capacity represents the amount of energy it can store, and it’s important to match it with the capacity of the power bank. For example, if you have a smartphone with a 3,000 mAh battery, you will want to choose a power bank with at least 3,000 mAh capacity to ensure that you can fully charge the device.

When looking for a power bank, you may also come across the term “output.” The output, measured in amperes (A), represents the rate at which the power bank can deliver power to the device. Higher output means the power bank can charge the device faster. However, you should also make sure that your device can accept the output of the power bank, as some devices may not be compatible with high-output charging.

In conclusion, watt-hours are a crucial measure of energy capacity in a power bank. The higher the watt-hours, the more energy the power bank can store and the more charges it can provide to your devices. When choosing a power bank, it’s essential to consider the watt-hours it offers, and match it with the device’s battery capacity in mAh. Laptop power banks offer high watt-hours and are perfect for business travelers or students who need to work on the go. Additionally, consider the output of the power bank, which is measured in amperes, and make sure that your device is compatible with the output.

Buyer’s Guide

Recharging devices has been an issue ever since the first cell phones were invented. Some of the earliest models needed up to 10 hours of charge time for only 30 minutes to an hour of talk time. But many great minds have been working on this issue for decades now, included inventor Wen-Chin Yang, who applied for one of the earliest patents for a mobile phone battery charger in 2000 (4).

Portable chargers are more efficient and lightweight today than ever before. But with technological advancements, there has also been a large increase in competition. To help you make your decision, our Buyer’s Guide will focus on capacity, size and weight, and charge time.

Capacity

The chargers above range from a capacity of just over 5,000-mAh to 24,000-mAh of battery power. What you’ll need will depend on a variety of factors, such as the type of devices you plan to charge, how many devices you’d like to charge at the same time, and the amount of time you anticipate being away from a traditional wall charger and needing to recharge devices.

At a minimum, we recommend a charger that you know can fully charge your device in one go. In order to figure this out, you’ll need to determine the energy capacity for your device. Once you figure this out, you’ll be able to compare with the battery power of several chargers to find one that can fully charge your phone without completely depleting its own battery level.

Size and Weight

Depending on your intended use, size and weight can make a big difference. Portable chargers are designed to be carried all day in a briefcase (for business travelers) or in a secure pocket in a bag or backpack (for outdoor adventurers). This means that a large, heavy battery might prove too cumbersome for some of you.

Generally speaking, batteries with smaller energy capacities are also going to be smaller in size. This can make finding a balance between having enough battery power and not having to lug around a super heavy battery all day a little tricky.

To make your decision easier, consider how much you’ll be moving around and carrying your portable charger. If it’ll primarily be sitting on your desk to recharge your phone throughout the day, size and weight are less of a concern than if you’ll be carrying it in your pack on a multi-day excursion.

Charge Time

It’s important here to make a distinction between the amounts of time it takes to recharge your battery pack and the time your battery pack takes to fully charge a phone or other mobile device. These two statistics can be easily confused when shopping for a new portable charger.

For example, some portable chargers need up to 10 hours to recharge when plugged into a wall outlet. This is fine when you’re at home and can plug it in for the night, but it gets a little tricky when you’re on the move a lot.

While solar chargers sound excellent for backpacking trips, they often require many hours in direct sunlight to achieve a full charge, which can also be difficult if you’re hiking every day. Chargers that can provide multiple charges for your phone or device on one full charge, then, are ideal.

Frequently Asked Questions

The terms ‘power bank’ and ‘portable charger’ are often used synonymously. They are both designed to supply extra power to phones, tablets, and other portable devices without the need for a wall outlet. In this section, we’ll explore some of the most Frequently Asked Questions about portable chargers, or power banks.

What is ‘mAh’?

For starters, ‘mAh’ stands for milliamp hours. It is a unit that is used to measure electric power over time. In general, the more ‘mAh’ a battery has, the longer the battery capacity or battery life. For example, a 5,000-mAh portable charger can power a device that draws 100 milliamps for 50 hours. It would only be able to power a device that draws 200 milliamps for half that time (25 hours).

Can I take a portable charger on a plane?

Back in 2015, some travelers became concerned when the FAA urged flyers not to carry “spare batteries” on flights. This, however, referred to loose lithium-ion batteries (like the ones found in your laptop or smartphone), and not to portable chargers.

How much battery capacity do I need to charge my phone?

This, of course, will depend on the type of phone you’re using. For example, an iPhone 7 has a power capacity of 1,960-mAh while a Samsung S7 has a capacity of 3,000-mAh. If you’re using a 5,000-mAh portable charger, then, you’ll be able to charge the iPhone 2.5 times and the Samsung only 1.5 times.

But if you only buy a charger with a 2,200-mAh capacity, you won’t be able to fully charge the Samsung in one go. So knowing the battery capacity of your phone (which can be found in the manufacturer’s specifications) is essential in picking a portable charger.

How long does it take to charge my portable charger?

This will depend on the total battery capacity of the specific portable charger in question. In general, however, chargers with a larger capacity will require more time to fully charge than chargers with a smaller capacity. Keep in mind that different charging methods (i.e. USB, solar, original charger) may also result in different charging time.

Summary

Many portable chargers also offer a variety of bells and whistles that go beyond the basics of battery capacity, charge time, and size and weight. But we hope that this article has helped you focus on the important aspects of a portable charger so that you can buy the one that’s perfect for you and your needs!

But if you only buy a charger with a 2,200-mAh capacity, you won’t be able to fully charge the Samsung in one go. So knowing the battery capacity of your phone (which can be found in the manufacturer’s specifications) is essential in picking a portable charger.

How long does it take to charge my portable charger?

This will depend on the total battery capacity of the specific portable charger in question. In general, however, chargers with a larger capacity will require more time to fully charge than chargers with a smaller capacity. Keep in mind that different charging methods (i.e. USB, solar, original charger) may also result in different charging time.

Summary

Many portable chargers also offer a variety of bells and whistles that go beyond the basics of battery capacity, charge time, and size and weight. But we hope that this article has helped you focus on the important aspects of a portable charger so that you can buy the one that’s perfect for you and your needs!
