Currently we all have the same problem: running out of battery , no matter the price, quality, brand, model, device, OS … all the devices we own need energy to work, unfortunately, that energy they have available is limited thanks to the batteries that include each of them.
Many of us have thought then I take the charger with me but it is not so simple, the sockets are not always available or, if they are available, you are not the only one who has thought about this and, therefore, there are few sockets for many people.
For this problem there is a solution: power banks , devices capable of providing that pinch of energy that each of us needs to be able to get to the end of the day without too many problems … and in this article we will give you some fundamental keys to choose the portable charger ideal for you!
Capacity, size and weight: the portability of a power bank is important!
A power bank is a portable device, so it cannot be too heavy or too big: carrying a brick with you is nothing comfortable and, obviously, nothing portable and in that case it would make no sense to buy a power bank .
There are three most common capabilities among power banks:
- 5000mAh: very portable and comfortable, ideal for providing that pinch of energy to a single smartphone deviceto get to the end of the day. They can provide a maximum of 50% battery.
- 10000mAh: these are also portable and comfortable, but they can also work to supply energy to more than a single smartphone deviceor a full charge of a smartphone plus a little more.
- 20000mAh: ideal for supplying power (even full recharges!) To various smartphone devicesor supplying power to devices that need higher power such as laptops .

However, 20000mAh power banks are not always capable of providing full or 0% to 100% charging to laptops .
Greater capacity means greater dimensions and weight.
Therefore you must always choose a power bank that is adequate for your needs and daily use, to help you better understand which is ideal for you you should ask yourself a couple of questions:
- How many people will use the power bank? You? Various people (friends, family…)?
- How often will you use the power bank? Sometimes, during the week, weekends ..?
Having asked these questions you should then take a look at the following graphics, both made by the PowerBank20 team , the first refers to the relationship between portability (intended as volume) and energy , the second instead refers to the relationship between weight and energy (done on 20000mAh power bank):
Portability / Energy Ratio: Which Power Bank Provides More Power in Less Space?

In this case it is the TeckNet IEP12000 power bank that provides more energy in less space, this means that among the 20000mAh power banks this model is capable of transmitting more energy (charge) to your devices without taking up as much space as its rivals. (but that doesn’t mean it’s the smallest!).
Weight / energy ratio: which power bank provides more energy and is less heavy?
It is the PB132 model of the Ugreen brand that provides the most energy without being too heavy (but it does not mean that it is the least heavy among all the models!), That is, more charge to your devices.
If you make a general balance, you protest choosing the Ugreen model because it is in second place in the portability / energy ratio and first in the weight / energy ratio, instead the leader of the first graphic is in the last places of the second graphic.
Models from brands like Aukey or Aideaz are also a solution: neither much nor little, in that case it’s worth a look at the prices ?.
Quick charge: Quick Charge, PD and many others …

The most famous fast charging protocols are Quick Charge and Power Delivery, very useful especially when entering power banks of greater capacity because standard charging also means 7/8 hours of charging.
On the other hand, they are useful for devices that need more power to recharge, such as new laptops with USB C or to take advantage of the various protocols that include smartphones, in order to obtain incredible results in a few minutes (think that the PD protocol it even reaches 100W!).
But… how does fast charging work? In the case of the discharge is simple or standard, the charging is done at 5V / 2A ( iSmart Output ) but when using a quick charge protocol ( Quick Charge Output ) the voltage goes from 5V to 8V , this translates into more speed!
Types of doors and extras!
You can find various types of ports on a power bank, let’s see them:
| Door | Micro-USB | USB-A | USB-C | Lightning | A.D | B.C |
| Entrance | ✔ | ❌ | ✔ | ✔ | ✔ | ❌ |
| Exit | ❌ | ✔ | ✔ | ✔ | ✔ | ✔ |

These are the most common port settings in power banks! And let’s not forget the wireless charging area, which currently works up to 10W.
As for the extras they can be various:
- LED flashlight
- Jump starter
- Hot Pack
- IP certification
