How to Choose the Best Type of Power Bank

Today, the fastest-growing type of charging electronics on the market are power banks. That’s because power banks are portable chargers that are able to go with us anywhere that we want. Most of the time we use USB wall chargers and the main flaw with them is that we have to stay close to them in order to charge our devices. This is a major problem when it comes to charging because we have things to do and places to be. Charging is something that we need and yet it holds us down at the same time.

Power banks solve the problem with having to stay in a single spot and charging our devices. With that said, as popular as power banks are, there are quite a lot of companies that now sell them. This is a good and bad thing. The good part is that there’s a lot of innovation that happens with power banks because there’s more competition. On the bad side though, there are quite a lot of companies that sell low-quality power banks that have poor traits and stop working after just a few weeks or months.

In this article, I’ll be going over the major points of a power bank that you should look out for when you’re purchasing one and what the best types are on the market.

Power capacity and size

The power capacity is a major part of a power bank because it’s basically the integral part of one since it’s the piece of it that you’ll be using the most. Depending on what the power capacity is, a power bank may be able to charge a smartphone only once or it can charge a smartphone and other devices multiple times over with its power capacity. Which brings us to the two main types of power banks on the market.

Low capacity

Power banks that have low power capacities that are within the 3,000mAh to 5,000mAh range are the most used. The reason being is that they have small sizes and they’re lightweight. The power capacity of a power bank is correlated with the size and weight of the portable charger. In this case, these power banks are so small that they’re able to fit into your pocket or you can hold them while you charge your smartphone.
However, these Mini power banks are not meant for multiple charges and most of them are only able to last for just a single full charge. They also only have a single charging port, so you can only charge a single device at a time and most of them don’t have the fastest charging speeds either. If you’re searching for more power, then it’s best to go for power banks that have higher power capacities.

High capacities

Power banks that have high power capacities are ones that are used a lot less and the reason for that is because they have larger sizes and heavier weights. The reason behind that is because they have higher power capacities, which means there are more batteries being used and larger ones as well. As a result, you won’t be fitting these type of power banks into your pocket and neither are you able to hold them for long periods of time.
However, on the powering side, these power banks are highly useful as you’re able to charge devices like smartphones, tablets, and even laptops to full power. They also use multiple charging ports, which means that you can charge lots of devices at once. What high capacity power banks also excel in is that they have special charging tech like Quick Charge and USB-C to charge compatible devices at their max charging speeds.

Know the amount of charging ports and their speeds

For the most part, a power bank that has numerous charging ports are ones that have high power capacities. The main reason for that is because they have more power that they’re able to split up without being fully depleted. It’s important to know that just because a power bank has many charging ports doesn’t mean that it’s a high-quality one. You must know the charging speed of each of those ports.
A power bank can have 3 USB ports but if all three of those port have a charging speed of 1 Amp, then that’s bad; because charging speed of 1 Amp isn’t going to charge most devices at their max speeds.

Instead, a good charging speed for a 3 port power bank is for each of those USB ports to have a charging speed of 2.4A. That’s because a 2.4A charging speed is a Max Standard charging speed. It’s basically a speed that is able to charge devices that are not compatible with Quick Charge or USB-C at their max charging speed. Most smartphones and tablets like iPads are able to achieve max speed. However, if you have a Quick Charge or USB-C compatible smartphone, then you should get a power bank that has those charging technologies.

Power banks brands are important

Since there are a lot of power banks brands on the market, you have to be careful from whom you’re purchasing your charger from. As I stated at the beginning of this article, there are a lot of companies that sell power banks that are low quality. These low qualities include: having a very large size for its power capacity, slow charging speed, and low build qualities that make the power bank stop working after just a few weeks or months. The worst thing is that these companies don’t have warranties most of the time.
You have to keep a lookout for companies that have a lot of positive reviews with not only their power banks but also with their other products. The brands that hold value with their power banks are the ones that innovate constantly and release new products frequently. They also have long warranties that prove that they’re positive that their products hold value and quality or else you’ll be getting your money back or a replacement.
