Factors to consider when you are about to buy a portable charger

The offer of portable battery chargers on the market is very wide, but how can you figure out which of the best power banks do you need? What are the factors to consider when you want to buy a power bank?

Continue to follow us because now we will deepen the most important of these factors.

When you consider the various purchase options, ask yourself: am I looking for a portable charger for everyday use? Therefore, it does not require extreme charging power. Or do I need products that you can support, maybe a whole weekend and even more?

Once this is done, also consider the dimensions: if you think you want to carry the portable charger in your pocket you have to orient yourself on slim or small models, so even the power will not be maximum. Finally the price: how much do you want or can you spend?

Put all this information together, narrow the field and then read the reviews of customers who are already using that power bank to get more details on how to use the product. The opinions of other users act as a real test.

But let’s not get lost in small talk! Are you ready? Please take notes!


One of the most important values ​​that you will need to take into consideration when considering a purchase is certainly its capacity. The capacity of a portable charger means the power, the maximum amount of charge that it is able to accumulate and it is measured in mAh. The greater the value, the greater its capacity to recharge a device several times.

To understand how many times a portable charger is able to charge a device you have to compare its capacity with that of the battery to be recharged. If, for example, a battery has a power of around 2 000 mAh, it can be recharged 3/4 times with a 10 000 mAh power bank. This is the best way to start understanding what your real needs are.

If you want to have a portable charger that can recharge your device for many days, surely you have to go on models with greater capacity. Clearly the greater the capacity of a portable charger and the higher its purchase price and also its weight and overall dimensions.

Another point related to the power you need to keep in mind is that the power value quoted, whether 2 000 mAh, 10 000 mAh or 24 000 mAh, are nominal values ​​that often correspond to an effective charging capacity of 15/20% . In this case the reviews (or tests) will be very useful because often users report, by experience, the number of times they have been able to reload their device. The best portable chargers will be those with the best performance.

Actual yield is not always linked to the brand. As we have also seen in our special ranking of the best power banks, you can find very high yields in products with a less known brand.

Ampere in Input

To get a better idea of ​​what the charging times of your portable charger are, you need to check the current input intensity value. You can have an input value of 2A, but power banks with a value of 1 or even 0.5A are still widespread. Once you know the value of the input voltage it is sufficient to divide the maximum nominal charge of the battery and divide it by this value and you will know how long it takes your charger to charge.

Recently, the best power banks have appeared on the market with input as high as 3A.

In all cases the percentage of charge is usually indicated by LEDs in different ways: by varying the number of LEDs lit or by changing their color. Some portable chargers even have a display, which certainly provides a better display of the charge values.

The inputs for the input can be: via USB or micro-USB, therefore with a wall socket, through photovoltaic panels (portable solar battery charger) or with a dynamo (not very common) that are recharged through a knob. The first are those with the highest yield, so the best compromise could be a power bank that includes a double charging mode.

Ampere in Output

In addition to the intensity of the input current it is also important to evaluate the intensity of the current output from the portable charger because it is the one that will give you a better idea of ​​the charging time of your device. Most chargers have one or more 1 or 2 A output ports, although many of the best power banks have outputs of up to 2.4A. The higher the output amperage the faster the charge will be.

To know how much current, in terms of Ampere, is able to deliver a charger, it is not enough to add the maximum power that can be supplied by the outputs. In fact, the one indicated is the maximum output value that can be supplied by each individual output, but often the total that can be delivered as a whole must be indicated by the manufacturer. Often the total payable is 3.4A or 5.4A (based on the total number of exits available).

In all cases, to make the best choice, always remember to also check the features of the devices you want to upload, so you will have a better idea of ​​the output you need.

Number of USB ports

At this point ask yourself a question: for how many devices will you mostly use the portable charger? If you use it especially for your smartphone, the best choice is definitely a power bank with a single USB output.

But if you need to recharge smartphones, electronic cigarettes and / or fit watches, then surely the best choice is a portable charger with 2 or more USB ports (you can easily find chargers with 4 outputs). What you need to pay attention to in this case is both the power of the portable charger, which must certainly be high, and the maximum output supported by each port, in addition to the overall output. Some portable chargers have equivalent ports, others have ports with different maximum capacity.

Output USB ports can be implemented with fast charge technology, which reduces battery recharge times. They can be more recent USB Type-C type ports: higher charging speed, but they are compatible only with Type-C cables: it is present in the best power banks, especially the most recent ones. The best ports are Smart, that is, they adapt the amount of energy delivered to the needs and characteristics of the battery connected to it, thus avoiding overloading and therefore degradation.


The portability of a portable charger is a feature that you must definitely consider, especially if you plan to always carry it in your pocket. If you turn your attention to high-powered power banks, don’t expect small or light products. If you have a strong need to always carry the charger with you but you can’t store it in a bag, the best choice is the portable chargers with around 10 000 mAh, a good compromise between efficiency and portability.

If, instead, for you it is fundamental the efficiency and above all the number of refills that is able to guarantee you, surely portability is not necessary you take it into consideration. Focus more on capacity or other features.


When we talk about evaluating the design of a portable battery charger we do not mean just pure aesthetics, which can still be important to you. We mean everything that makes the portable charger easy and convenient to carry, and maybe store, in complete safety.

On average the battery chargers have a parallelepiped, more or less slim, thin appearance. The dimensions are often related to power. The shell is often made of plastic and must certainly be solid enough and scratch-resistant, so possibly not excessively smooth and delicate. Some products, not necessarily the best ones, have a more or less colorful aluminum shell that is certainly beautiful, but very delicate and easily stained or scratched.

You must also evaluate when it is handy and comfortable to carry in your hand: a particularly slippery portable charger is not useful because it can easily fall from your hands and break. In order to make a better evaluation of the product, the reviews of the various customers will be very useful where often the dimensions and the practicality of the product are reported. For color lovers, some brands produce their own power banks in different colors.

And your phone will never be turned off

At the end of our article you will surely get the clearest ideas about the world of portable chargers. Now you know how to read the main information that characterizes these products and how to choose the best portable charger for you, the one that best suits your needs. Remember, of course, that you can use power banks for mobile phones, tablets, cameras, smartwatches or electronic cigarettes: in short, a precious little treasure.

Put all this information together, compare it with the opinions of other buyers, evaluate your real needs and proceed with the purchase. Just one click and your phone or tablet will always be charged! What are you waiting for?
