Portable charging has been on the rise since power banks came to the market and the main reason for that is because power bank s are portable chargers that can be taken anywhere. All the other types of charging electronics that we use are stationary and require that we keep our devices in single place. Thankfully, that’s not the case anymore because we have portable chargers that allow is to be free while we charge our devices.

With all that said, since power banks have grown in the marketplace exponentially, there are now many companies that sell them. This has caused there to be lots competition that has resulted in quite a lot of innovation and the innovation has brought many types of power banks to come into existence. With so many power banks filling the marketplace, it can be hard to tell what you’re supposed to look for in terms of specifications.

That is why, in this article, I’ll be going over the main parts of a power bank to know so that you’re able to choose the best power bank for yourself

Different Measures of Portability and Use

All power banks are portable, otherwise, they wouldn’t be called power banks or portable chargers in the first place. With that said, the power capacity is in control of three main features that these types of charging electronics have. That would be the size, weight and how you’re able to utilize the power bank. Which brings us to the two main types of power banks on the market.

There are ones that are Very Small

The power banks that are very small are the ones that are used the most, and the reason these types of power banks are able to be so small and lightweight is that they have low power capacities. A low power capacity, in this case, allows these power banks to only use a single battery most of the time. Which allows them to take on forms factors such as being cylindrical and also slim. Slim power banks are among the most useful types as they basically have the same form factor as a smartphone.

There’s really no compromises when it comes to portability with these power banks.

However, the main flaw that these types of power banks have is that they don’t have very much power to use, and the most of the time they’re useful for charging smartphones to full power then needing a recharge. You can’t rely on these Mini power banks for days while you’re out camping.

There are ones that are Quite Large and Heavy

Power banks that are larger and heavier are the more useful types of power banks. The reason for that is because they have higher power capacities and more USB ports. It’s with their power capacity that you’re able to charge smartphones and lots of other types of devices to full power multiple times over. Then there’s the use of many USB ports so you can charge many devices at once.

One of the most notable difference is the use special charging tech such as Quick Charge and USB-C that these types of power banks that can be very useful for those that own compatible devices. However, as I mentioned before, that these power banks are larger and heavier, and the reason for that is because they use multiple batteries. Most of them are not able to fit into a pocket or be held comfortably for long periods of time.

Power Bank Charging Speeds

Power banks might be portable but they’re still charging electronics, and just like any charging electronic, we just want our devices charged so we can stop using the charger.

When it comes to Mini power banks you’re mostly going to be dealing with slow charging speeds, but there are quite a few Mini power banks that are within 5,000mAh power capacity range that have faster speeds that are in the 2 Amp range; but in general Mini power banks have slow recharging speeds as well because they have less power to recover and can be recharged rather quickly.

However, when it comes to power banks that have multiple USB ports and higher power capacities, then that’s when Output and Input charging matter more.

1.0 Amps = Slow Charging

2.0 Amps = Moderate Charging

2.4 Amps = Fastest Standard charging

3.0 Amps = Quick Charge and USB-C

If possible, if you’re getting a power bank that has multiple USB ports, then it’s best to purchase one where all the ports are capable of outputting 2.4 Amps. That way, you’re able to charge all devices that are not compatible with Quick Charge or USB-C at their max charging speeds.

As for devices that are compatible with Quick Charge or USB-C, then it’s best to purchase power banks that feature those type of charging technologies for max charging speeds.


All the above are important criteria to look at when you’re purchasing a power bank, but of the most important that come before all that, is knowing who you’re purchasing the charger from.

The reason for that is because even though there are many companies that are innovative, there are also many companies that sell low-quality power banks too. These companies set themselves up as offering the best of portable chargers with “fast charging speeds” and “Small Portable Sizes” but that could mean anything. A fast charging speed for them could be 1 Amp and a portable size could be something that weighs 1 pound.

So it’s vital to take a look at the specifications of the power bank and also to take a look at the power bank reviews that can be found at ChargerHarbor.com. By looking at past customer reviews that they have left behind, you’re going to be able to get a better idea of what kind of experience you would have.
