What is a Power Bank and how to Choose One

Most us simply use USB wall chargers for charging our devices and it makes sense as USB wall chargers have fast charging and they also have many charging ports. However, the problem with using USB wall chargers and charging electronics alike is that the devices that you’re charging must stay in a single place. That can be a problem and normally is because we want to go places and do things and not have to wait for our devices to charge.

What is a Power bank?

That is why power banks are becoming increasingly popular as they’re portable chargers that have their own power capacities and can be taken anywhere. With that said, there are lots of power banks on the market and that is why there are many different types. That is why in this article, I’ll be explaining the major parts that make up power banks and how you should go about choosing one.

Power banks are based on Power Capacities

A power bank can’t be a portable charger without its power capacity and it’s one of the most important parts of ones. That’s because there are two types of power banks that are common among them all.

Mini – Power banks that are “Mini” are ones that have low power capacities. A low power capacity mostly ranges within the 3,000mAh to 5,000mAh range and they’re so small that they can fit into your pocket and they’re also lightweight enough that they can be held for long periods of time. The most useful types of Mini power banks are Slim ones because they’re about the same size and have the same Slimness as your smartphone. With all that said, as popular as Mini power banks are with the masses, the main thing to remember is that they’re meant for just 1 or 2 full charges before they need recharging.

Large – On the opposite side of Mini power banks there are larger high capacity ones. In general, in these ones are a lot larger and heavier and that means not as many people use them. With that said, a high power capacity offers more long lasting power. In addition to long-lasting power, these larger power banks also have multiple USB charging ports which means that you can charge many devices at once with them.

Lots of other types.

In addition to having different power capacities, there are quite a lot of other types on the market.

Such as Solar power banks. Solar power banks have Solar panels on them and that means that they can recharge using light from the Sun. They types of power banks are basically like Rugged power banks as well, which means they have reinforcements that allow them to withstand drops to the ground which makes them shockproof. They’re also able to be waterproof when their USB charging ports are covered. Overall, Solar power banks are the perfect type of portable charger for the outdoorsman.

There are also power banks that have built-in cables and these ones are able to be reliable at all times. Since power banks are portable there are times when people forget to bring their charging cables when they’re on the go. Having built-in charging cables means that your portable power will always be reliable. Another thing is that these types of chargers also have built-in recharging methods such as AC Adapters or USB cables to recharge themselves.

Charging Speeds and Recharging

When it comes to charging speeds, it’s one of the most important parts of a power bank because it’s the part that you’re actually experiencing and you want to detach from the power bank as soon as possible.

Here are the basic criteria when it comes to charging speeds:

1 Amp = Slow Charging

2 Amp = Intermediate Charging

2.4 Amp = Max Standard Charging

3.0 Amps = Quick Charge and USB-C charging

For the most part, many Mini power banks are the ones that use 1 Amp charging; however, with newer Mini power banks there are ones that are going into the 2 amp and beyond range.

With that said, charging speeds are vital for when you’re using a high capacity power bank because they have multiple USB charging ports and so you want each of the devices that you’re charging to charge at max charging speeds.

Most smartphones nowadays are able to charge at the 2 Amp range and beyond. Then you have to consider if your smartphone is compatible with Quick Charge or USB-C if it’s an Android smartphone and if so, then you should get a power bank that features Quick Charge or USB-C. Tablets like iPads have a max charging speed of 2.4A and there are quite a lot of power banks that feature 2.4A Outputs as well.

Recharging

Another important aspect of charging is the recharging process because you want your power bank to be useful again as soon as possible. Most Mini power banks have “Okay” charging speeds because they have less power capacity to recover. Then there are high capacity power banks where recharging is more important.

Great recharging methods for a power bank that has a high power capacity are ones that have 2 Input Micro-USB ports and that results in 4A recharging which is very fast. There are also some power banks that have a single Input port but the Input port is either USB-C or Quick Charge; however, with that type of recharging, you’re going to need a Quick Charge USB wall charger for fast recharging.

Whom you’re purchasing from

The last and one of the most important parts of getting power banks is knowing who you’re purchasing from. There are lots of companies that claim that their power banks are of the highest quality and yet the power banks that they sell feature slow charging, and most of their high capacity power banks have slow charging with their USB ports.

Make sure to take a closer look at the specifications of their products and take a look at their products reviews. As that’s a great way to make sure that you’re purchasing from a trustworthy source.
