I have prepared this buying guide to explain to you about some of the critical factors that you need to consider before you go out there and make the investment.
Out of all these factors, find the one that you think is important according to your usage and get yourself the best power bank!
The first and foremost thing that you need to consider is the total capacity of the power bank that you need to buy.
Milliamp-hour, or most commonly written as mAh, is the unit for measuring the capacity of a battery. The bigger the battery, the more juice it can hold. The easiest way to determine how much capacity you need is to take into account your device battery size and how often do you need to recharge it through the day.
For instance, an iPhone X has a 2716mAh battery. This means that with a power bank with 10000mAh, you can recharge an iPhone X just over 3 times. Considering that you do not use the phone excessively, a 10000 mAh bank would be good enough for at least a couple of days (if you charge the phone alone).
Contrastingly, if you need to recharge your smartwatch, your tablet, your headphones, and your phone, you might have to consider going for a bigger battery power bank, with around 20000mAh. That too would be good for a day or two at most. Similarly, there are power banks with AC outlets that are capable of charging a laptop as well. You can consider getting one if you want to charge your laptop too.
Ultimately, you have a variety of different capacities to select according to your needs. All you need to do is consider how much energy you use and it will be much easier to choose one.
Size and Weight
The next most essential thing to take into account is the size and weight of the power bank.
Power banks are supposed to be convenient and portable. They wouldn’t be very comfortable if you are walking around with about a kilogram in your pockets (that too if it fits).
Therefore, you have to consider the weight and the size before you buy one. You must know that a bigger battery with more mAh takes up more space and is considerably heavy too!
To help decide what would be the ideal size and weight for you, here are some situations. Firstly, if you are a tech guy and roam around with a backpack full of gadgets, a more massive power bank would not be a problem. It will have enough juice for all your gadgets, and you can place it safely in the bag with the rest of the devices.
Contrastingly, if you just roam around with mobile and maybe some other device like your headphones or a smartwatch, you should get yourself a lightweight and compact power bank that can fit comfortably in your pocket.
Ports and Voltage
The amount of input and output ports along with the voltage is also worth considering.
The most common port found in power banks is the USB Type-A/USB 2.0 port. It is a universal port for charging most, if not all, devices. However, the world is now transitioning towards USB Type C, which is faster, and it combines both input and output from just one port.
Moreover, there are separate ports for laptops if you want to charge them up as well. Hence, you need to consider what kind of ports does the power bank has and whether they are sufficient to charge up your devices. More compact power banks come with just one or two ports, whereas the bigger ones have four or more to charge up your devices simultaneously.
As far as the voltage is concerned, you need to check whether it is compatible with your device or not. This can help you prevent any sort of damage to your device and safeguard you and your other devices.
Lastly, you need to consider how much you are willing to spend on a power bank. With a price set in mind, it will be much easier for you to decide which power bank meets your needs, as there are multiple options in the same price bracket.
A compact and lightweight power bank would set you back about $30-$40, whereas a bigger power bank would go over $100. In the end, it is a matter of personal preference.
Often times, companies give out their products with generous warranties.
It would be better if you choose a power bank that came with a warranty to protect your interests. Popular brands like Anker, Aukey, etc. ship their products with a year warranty at least.
Having LED indicators to show the remaining battery in the power bank can come really handy.
You would precisely know when to recharge your power bank and never have to worry about running out of juice in the middle of the day.
If your device supports fast charging, it is worth considering whether the power bank supports it too or not. It can significantly help you to recharge your devices at a considerable less time.
Also, you need to see if the power bank itself charges quickly or not. A power bank with 20000mAh can take well over 7-8 hours to recharge. Hence, you need to see how much time does the power bank takes to recharge once it discharges fully.
