At that time, having a portable charger is critical. For those who spend a lot of time away from home, or for those who travel and spend hours at airports and bus stations, a power bank can also be very useful.
But how to choose the ideal model? Below, we will answer some questions that will help you in this task.
What is a portable charger?
A portable charger, or power bank, is basically an external battery like the common lithium-ion battery in smartphones.The difference with it for a typical internal smartphone battery is that it operates by receiving and supplying power through its USB ports, allowing the battery itself to be charged to charge another device accordingly.
Therefore, it is basically a portable battery for you to carry with you and solve your battery outage problem anytime and anywhere.
Its use is significantly simple: when you run out of battery on your smartphone, tablet or other compatible device, just connect it to the portable charger and press the power button.
Depending on the manufacturer and model, in addition to the box with external battery, support for USB inputs and an on / off button, the chargers may contain features such as an LED display indicating the percentage of charge, an LED flashlight and others.
With the portable charger or power bank you can use your mobile devices like smartphone, tablet, camera, iPod, MP3 and MP4 players, hand held video games anywhere, anytime.
What are the advantages and disadvantages of a power bank?
If you are tired of running out of battery outside your home and suddenly find yourself unable to make calls or send messages, check Google, your email or listen to music, know that you are not alone.The situation gets worse when you rely heavily on your smartphone for work. Being able to stay connected even outside the home or office becomes, in this case, something not only important, but essential.
One way or another, the portable charger ended up becoming a necessity. Nowadays people are increasingly connected and want to spend all day online and on social networks.
Therefore, it is common to fear smartphone and tablet users , especially heavy users . And the magic solution for those who do not have a socket available at that time, is a portable charger or power bank.
In addition, with the power of the devices lasting much less with the abundance of features that they currently bring, what to do in an emergency?
It is not uncommon for people to get lost in the woods on trails or forests, or even in traffic, and are unable to guide themselves with the GPS as they were in hand with the cell phone without a battery.
But if you’re not that radical, you may just be wanting to feel equipped for when you run out of battery on your smartphone during that trip by car, bus or plane. The portable charger is sure to be that extra battery charge when you’re away from any outlet.
Here the device is being increasingly sold, and with the vast majority of them being compact, they take up little space and are very portable for you to carry with you anywhere.
As our smartphones do not come with batteries powerful enough to last the desired time, the portable charger or power bank is already considered a very popular alternative for Android, Windows and iOS devices.
With the portable charger, whenever you need to enjoy a few more hours of use on your device or give a complete recharge wherever you are, just connect your phone to the power bank and that’s it!
Is it worth buying a counterfeit?
Of course not. Some people out there say that some chargers are not what they expected, that they often let them down and that buying a power bank is just throwing money away.If you hear someone complaining, know that they are likely to have made a wrong purchase. Many shopkeepers and places offer counterfeit or poor quality products and for those looking for just price, it can happen.
So stay tuned. Keep in mind the purchase of a portable charger that is reliable, because otherwise, in addition to ending up being on hand when you need it most, your smartphone or power bank may even end up burning.
But do not worry. In this Shopping Guide we will show you how the portable charger works, make comparisons, give all the tips and tell you exactly what you need to observe if you decide to buy yours!
Taking into account factors such as your routine, how many devices you have that need recharging and how important it is for you that they are always on, you can decide whether you need one or not.
Although the current models on the market are very similar to each other, the characteristics of the power bank can vary greatly, so it is necessary to note which is the best option for your smartphone and your needs.
So if you are already decided on yes, follow how the portable charger works and how to choose the ideal model for you.
What is the ideal charging capacity for a portable charger?
Portable chargers, although the vast majority have very similar design and functionality, have relevant characteristics to be taken into account by the future buyer.
The charge capacity of the battery, for example, is one of the first things to note.
It is this number that will indicate how much battery of your smartphone or tablet can be charged and how many times without you having to recharge the portable charger.
For example: if your smartphone has a charging capacity of 2,500mAh (milliamp-hour measure), you need to have a charger with that same measure for minimum recharge.
If the portable charger has 5,000mAh, you will be able to charge your phone in it twice. If you buy a 10,000mAh one, your smartphone can be charged four times. Therefore, considering purchasing a higher capacity one represents more recharges for your smartphone.
The indicated is that you buy one with at least the same capacity of the battery of your smartphone, information that can be verified in the specifications of your cellular. With it you can at least give a full charge when you need it most.
But here is the question: if the idea is already to invest in a portable charger, why not buy one with a few spare loads so you don’t end up having to go through the same problem of being unable to charge?
Another specification to be observed in addition to the battery capacity is the battery power. Your smartphone or tablet will only charge if the battery voltage is the same or higher than the power of your device.
This is measured in Watts (W), and these types of information are usually present in your device’s manual, on the charger or even on the battery itself. The more power it has, the faster it will charge.
The portable charger or power bank can also come in different shapes, sizes and prices.
As we have already pointed out, a disadvantage of this type of market is that there are many poor quality devices and many counterfeits. Therefore, there are chargers in basically any price range.
We recommend that you try to buy models of known and quality brands, avoiding the famous “xing lings”.
You can find good portable chargers with good cost-benefit from R $ 60 to R $ 100 reais. From R $ 100 to R $ 200 reais you will find excellent chargers, with greater loading capacity. Naturally, the price of these types of chargers is higher.
Where to buy?
You can find a variety of portable chargers at physical electronics stores and online. If you prefer to buy yours physically and talk to a seller, look for a reliable one near you.If you want to buy online from the comfort of your home, sites like Amazon from departments like Walmart have models at your disposal.
You can also find a good charger on marketplaces like eBay.
Purchasing criteria: Factors for comparing portable charger models
Here, we will talk point by point about the important criteria that differentiate the models and need to be observed to choose the one that best suits your needs.
- Types of portable charger
- Loading speed
- Weight and size
Types of portable charger
There are three types of portable chargers: external batteries with USB port (which we discuss in this article), those that come attached to cases for smartphones, and those that work with sunlight.
We consider external batteries with more functional USB ports, since they have more battery capacity, they can charge devices simultaneously and for many more times.
Case-shaped chargers are known to be practical, as you won’t need to take another device with you other than your own device (such as a smartphone or tablet).
But the greater the capacity of the battery in the charger case, the heavier the device will be with the extra case. Her battery is also only charged when the device is plugged into a power source.
An external power bank, on the other hand, can be recharged as soon as you have another USB port at your fingertips, which could be the computer’s, for example, and while it charges your smartphone it can be used without any problems.
Solar power banks, on the other hand, are the most independent. They have, in addition to photosensitive recharge cells, USB ports equal to the USB charging power bank.
Because of this, you can use them both indoors and outdoors, but the reality is that charging can take even longer than those that charge via USB.
Despite this, both the portable solar charger and the conventional USB charger charge not only smartphones but other devices, such as tablets, GPS, Kindle and portable speakers.
As we said before, when it comes to battery capacity, the calculation is simple. The average capacity of smartphones ranges from 1,800 to 2,600mAh (milliampere-hours).
So, what you need to do is to know the battery capacity of your smartphone, which is how much minimum charge you will need. If it is 2,000mAh, for example, a 4,000mAh charger will serve for two charges.
Another issue to be observed in the battery question is the number of cycles in the battery. The whole battery has a certain durability, and eventually they all start to lose their load capacity.
Generally, 500-cycle batteries are the ones you will want to buy, as they last up to a year and a half with daily recharges.
A precaution that must be taken so that the number of cycles lasts longer is to avoid incomplete refills, such as those ranging from 10% to 100%, for example. To prevent it from having a drastic drop in battery potential, you should recharge the portable charger only when its battery is completely zero.
Thus, the power bank does not spend unnecessary cycles, and there is also no easy way to check how much battery it still has. The indicated there is to buy a portable charger with LED display.
Portable chargers come with different charging speeds, and today’s devices mostly range from 1 to 2A (amp). The portable 2A speed charger will charge your smartphone or tablet faster than the 1A, as logic suggests.
But there are a few pitfalls: if the charger has two USB ports, for example, only one of them will give you that much charging speed.
If you use a type C USB port, which allows devices to be charged with greater power, the charging speed can be increased. In some cases it even doubles.
The portable charger or power bank can also come in different shapes, sizes and weights.
As previously mentioned, the portable charger with the highest load capacity is likely to be larger and heavier due to the entire structure required for storage.
Today, however, some models already have a high loading capacity in compact and light weight versions, which is something to be observed at the time of purchase.
For a portable device, especially like the charger or power bank that requires you to take it with you whenever you are also with your smartphone, it is more comfortable that it is lighter.
If you usually carry a backpack on your back, it probably won’t make much of a difference, but for women who usually carry a shoulder bag, a very heavy device can end up getting in the bag.
The portable charger or power bank comes with a USB cable for your inputs and it is detachable, so you don’t have to worry about carrying multiple cables wherever you go.
