One of the fastest growing charging electronics on the market are power banks and the reason for that is because they’re portable chargers. We’re used to using USB wall chargers for charging electronics and it makes sense to do so because USB wall chargers have lots of USB ports, fast charging speeds and most of them are small enough to be taken anywhere and used. With that said, as useful as wall chargers are, they require that our devices stay in a single place for charging.
Since power banks have come into the picture that has all changed because now we can charge our devices no matter where we are. As portable chargers have increased with their popularity, there have been companies that are selling them and that has resulted in there being many different types of power banks on the market.
It can be confusing to know what power banks should feature so that it’s up to your specifications, which is why, in this article, I’ll be going over the main features that you should look out for when buying a power bank.
Power Capacity, Size, and Weight
A power bank can be taken anywhere no matter its power capacity, but it’s also important to realize that the power capacity is into control of the size and weight of the charger. The less the power capacity, then smaller the power bank will be and more the power capacity then larger and heavier the power bank.
Let’s go over the Pros and Cons of both of them.
A power bank that has a low power capacity means that it’s going to be using very few batteries. For example, the ones that have 3,000mAh to 5,000mAh power capacities are ones that only use a single battery for the most part and that results with them having a small size and lightweight. One of the most useful types of form factors is being Slim because a Slim power bank is one that is about the same size as a smartphone and can fit into a pocket seamlessly. As a result of being so easy to carry, a low power capacity power bank is one that is used the most.
As portable as these ones are, they’re not meant for long-term use because the power capacity is able to charge most smartphones about once or twice before needing a recharge.
Ones that have high power capacities are ones that are a lot more reliable to have. The reason for that is because a high power capacity of 20,000mAh or higher is able to charge devices such as smartphones or laptops to their full power multiple times. Another awesome thing that these ones have is the use of multiple USB ports so that you can charge lots of devices at once.
As useful as these types of power banks are, a high power capacity means that they use many batteries and that results in the power bank itself being large and heavy. Some of these large power banks can fit into your pocket and you can hold them; for the most part, though they’re meant to be set down and used as it’s more convenient.
Charging speeds are important no matter what charging electronics you’re using, even when it comes to portable chargers because we want to stop relying on a source of power and be free.
With that said, there are two main charging speeds that you need to be considered about when it comes to a power bank and those are the Output and Input.
What is Output
The Output charging speeds is the charging that your devices receive and it matters because you want your devices to charge up to a good point so you can disconnect from the power bank. Most Mini power banks have slow Output charging speeds, but there are newer ones that are able to feature faster speeds.
What is Input
Then there are the Input speeds and the Input charging speeds are the recharge and Mini power banks also have slow charging here too; as they have low power capacities to recover.
Charging for High Capacity Power Banks
With all that said, charging speeds are a lot more important to know when it comes to power banks that have high power capacities. The reason for that is because they have multiple USB ports, so if you’re charging many devices at once, you want each of them to charge at good speeds.
For the most part, it’s best to get a power bank that has multiple ports to have each of its ports at a charging speed of 2 Amps or higher. As most smartphones and tablets are able to charge faster at 2 Amp speeds. Then you have to consider charging tech such as Quick Charge or USB-C because there are a lot of Android smartphones that are compatible with the charging tech and can charge very quickly if they’re used with the tech. Even new MacBooks are using USB-C charging.
Also, Input charging needs to be great when it comes to power banks that have high power capacities because you want to be able to use it again. One of the best practices of recharging is when a power bank uses two Input ports or if they take advantage of Quick Charge or USB-C when it comes to recharging it.
Brands that you Purchase from
There are lots companies that are now selling power banks and at the beginning of this article, I made it sound like a great thing, which it is; but there’s also a dark side with having so many companies within this portable charging market.
With that said, there are companies that provide value and there are ones that don’t. In order to know the difference, it’s vital to look past the promotion and advertisements and see what the specifications of a power bank are. Some companies may claim that they have the fastest charging speeds, but if you take a close look you’ll realize that it’s not true.
Also, another helpful thing to do is to take a look at the product reviews because that way you’re able to know how you’d experience a power bank if you bought it.
