Tips For Buying A Power Bank For Your Smartphone

We live in a society that increasingly needs various electronic devices designed to facilitate everyday life, including the now inevitable smartphones, laptops, tablets … and all of these have one thing in common: they need a battery to to work!

But not only that: to these products we must add some accessories that in the past did not need to be recharged so frequently (because they did not have as many features as they do now) or batteries to work, such as the various smartwatches, smart bands, speakers, earphones. Bluetooth and many more

The problem with this increase in devices that require constant energy to function is that we have to pay attention to the charge levels so as not to allow them to stop working when we least expect it.

What is the solution?

Maybe bring a charger with you, but you don’t always have the possibility to connect it to a wall socket, and it is for this reason that power banks were born, devices that provide that pinch of extra energy that everyone needs. your accessories!

How to choose the right power bank?

With so many models in the market. It is not known whether it is better to focus on price, capacity, charging technologies … don’t be panic.

Fast charging technologies on power banks: Quick Charge 3.0 and Power Delivery
The two aforementioned technologies are the best known in the world of fast charging. Because they are the most “universal” in the sense.

They have a wide compatibility with  various brands of smartphones and computers.

Do you know how these technologies work?

It’s simple, instead of just increasing the amperage in the charging process. They increase the voltage, which allows for a higher energy transfer rate, in other words, much faster and safer charging..

It is precisely for this reason that on the 20000mAh power bank you can appreciate notable improvements, sometimes passing charging times from 6 hours to 3 hours or even less * (depending on the model / brand / power).

* In these cases you will need to use a charger compatible with the above technology (QC or PD).
Thanks to the tests carried out by the staff of the PowerBank20 site, you can compare many models of power banks and see how they behave in the various charging modes, for example, below we see a graph showing the charging times in standard power mode 20000mAh bank:

In this case, as can be seen, the minimum charging time is 6 hours.

Now let’s see how power banks behave with Power Delivery charging technology:

We remind you that in these cases the chargers to be used must be compatible with PD technology.

Charging ports of a power bank: how many and which ones?

As mentioned in the question, it is always important to ask yourself what your needs and how many and which ports your next power bank should have.

For example, if you don’t have devices with a USB C port, then it wouldn’t be necessary to buy one with this technology but in the future it is likely that you will need it (many smartphones app and laptops are starting to include it, now even monitors!).

And remember that there are input ports (usually micro USB, USB C or, in less common cases, Lightning or DC) and output ports (USB-A, USB-C …) and not all power banks have them all. , even if some models try, like this Romoss with three different entrance doors:

Attention: that it has three ports does not mean that it allows multiple charging (like this case), i.e. charging multiple devices at a time through the three ports. The brand must indicate this on the product description.

Capacity, size, weight… and the extras!

The rule to follow is very simple: + capacity = + weight and dimensions. To this rule you must add two questions that are fundamental when choosing a power bank:

Who will use the power bank?

One, two or more people …

How many times will I use the power bank? Every day, once / twice a month …
Based on all this, our advice is to take a 10000mAh or 20000mAh power bank because they are capable of providing one or more full recharges to the various devices.

To be taken into consideration is the type of battery that the chosen power bank has, if it is Lithium-ion 18650 batteries the power bank will be bigger, however, if it is a Li ion battery it will be thinner: attention, let’s not talk of a scientific law!

The extras depend on each brand: presence of LCD / LED screen, protection against dust / water and / or falls, compass, flashlight, solar panels, case included in the package.
