In today’s world we’re used to being able to access news and information at our fingertips, interact on social media, perform research, and communicate instantly, from anywhere, through our electronic devices such as cell phones and tablets. Our mobile devices require battery power in order to keep us constantly connected while on-the-go, and since everlasting batteries have yet to be developed, we need a power source to power our devices while out and about.

You may be asking yourself, how do power banks work? Which charger is best? Which one should I buy? Will this work on my iPhone or Samsung device?

Power banks are one of our favorite products, as well as a one of our best sellers! We’ve taken all of our knowledge of power banks and portable charging, and compiled it into this helpful guide to assist you in choosing which power bank is the right one for you!

What is a power bank?

Simply put, a power bank is an external power source which can be used to charge your phone or any portable device with a USB port.

How do I charge the power bank?

Since power banks come uncharged, you’ll need to plug the power bank in before its initial use with your device in order to build up the battery power. You can charge the power bank via a USB wall charger or by connecting it to the USB port on your desktop computer or laptop.

How long do I need to charge my power bank?

The time to a full charge can vary depending on the capacity of the power bank itself, as well as the charging method used. A power bank with a higher charge capacity is going to take longer to reach a complete charge opposed to a model of a lesser capacity. Also, charging with a wall charger and the original USB connector usually results in a quicker charge than plugging into a laptop or using a foreign charging cable.

What is mAH?

mAH stands for milliAmpere-hour. This is the unit of measurement used to determine the capacity of power banks.

Tips For Buying Power Banks

 

How Many Charges Will I Get? 

The primary attribute that differentiates various power banks is their capacity. The capacity is measured in Mah, and while it’s difficult to pinpoint exactly how many charges a specific power bank will give your devices, the standard rule of thumb is the higher the mAH rating, the more capacity the power bank holds.

For example, a cell phone with a battery rated at 1500mAH will be able to receive one full charge from a power bank rated at 1500mAH. It’s important to purchase a power bank that at least matches the mAH of your portable device. If the mAH of the power bank is lower than that of your device, it will not work or provide you with the results you desire. If you want to get multiple charges out of a power bank for your device, you can purchase a power bank with a higher mAh rating than your device battery. So if you’re buying as a promotional item, giveaway, or gift for employees, it makes sense to err on the side of caution and choose a higher mAh to ensure they will work on various devices.

You can find the mAh specs of your device located right on the battery, but we’ve provided the mAh of some of the most popular portable device batteries here:

Samsung Galaxy S7 – 3000 mAh

Samsung Galaxy S7 Edge – 3600 mAh

Samsung Galaxy S6 – 2600 mAh

Samsung Galaxy S6 Edge – 2600 mAh

Apple iPhone 6 Plus – 2915 mAh

Apple iPhone 6 – 1810 mAh

Apple iPhone 5S – 1570 mAh

Apple iPhone 5C – 1507 mAh

Apple iPhone 5 – 1440 mAh

Apple iPad 4 – 11,560 mAh

Amazon Kindle Fire HD 7 – 4400 mAh

Samsung Galaxy Tab S 8.4 inch – 4,900 mAh

Samsung Galaxy Tab S 10.5 inch – 7900 mAh

It’s also important to note that the efficiency rate of power banks is about 50%-60% of the stated capacity. This is due to the conversion of the charge from the power bank batter to your mobile device, and the loss of power that happens through the USB cable.

Match Your Charging Power

Along with exceeding, or at least matching the mAh capacity of your devices battery, you also want to make sure you choose a power bank that suites your devices charging adapter. You’ll want to choose a power bank that is equal to, or more than the output voltage and output current listed on the factory USB charging adapter provided with your device. This will ensure that that the power bank charger can charge your device at a rate similar to that of your factory wall charger.

Other Options To Consider

Size and portability is something to keep in mind when purchasing power banks. While all power banks are designed to be a charging source on-the-go, they come in various shapes and sizes. Whether you want to be able to carry it in your pocket, or throw it in a purse or book bag, this should be taken into consideration when determining which power bank is best for you.

Charging multiple devices is also a selling point when it comes to power banks. Do you want the ability to charge more than one device at the same time? Then a power bank with multiple USB ports may the right option for your technical needs.

Whether you’re constantly on the road making calls and doing business, listening to music and browsing social media, or on a road trip using your phone for navigation, a power bank is a great item to have as both an everyday accessory, and an emergency back-up. With a power bank portable charger, you’ll never have to worry about being unplugged from your device.
