For those of you who are not very familiar with the term “Power bank”, a very active and researched item on the market, you must know that a “Power bank” no longer has the original meaning which referred to the power storage that provided electricity to households. As of now, “Power banks” are regarded as the external battery packs for mobile devices. Power banks come with rechargeable batteries – either lithium polymer batteries or the 18650 type, – and are able to provide emergency battery power to virtually any mobile phone when it shows low battery, or extend the working time of a mobile phone. What`s more, Power banks can juice your mobile phones anywhere, anytime, especially when on the go!
Fiercely competitive on the market – just like mobile phones are, – various types of power banks keep emerging one after another in short periods of time. There is a wide range of power bank suppliers on the market who keep claiming that the power banks they manufacture are the best ones and the most competitive on the market. Whether we are talking about a real store or an online store, we will discover that there are various available brands for our selection. Some are famous and reputed, while some others are barely emerging and striving to make a name for themselves.
However, some of the power bank suppliers that we can find on the Internet are, to a certain extent, unreliable. And, the worst part is that they usually provide some of the worst power banks you could find out there. It may happen for the battery to die after using it only one time; and things can get even worse if there is no guarantee or warranty from them.
Therefore, it is important to keep in mind that sorting out the best power banks available on the market and maintaining our brand might save us a lot of money in the long run. Here are some tips on how to determine the value and reliability of a power bank.
The first thing we should keep in mind is the battery type that is assembled in the power bank.
As already mentioned above, we can choose between several types of batteries: from lithium polymer to 18650. There is no doubt that the most reliable are the lithium polymer ones, which currently enjoy a great reputation on the market. With this type of battery, you will not have to worry about explosions.
Battery transformation ratio
Another important aspect to keep in mind is the battery’s transformation ratio that determines the quality and performance of the power bank.
For example, in the case of 10000mah capacity power banks, their transformation ratio is 80%, meaning that a fully charged power bank has an actual output of 8000mah. The battery of an iPhone has 1500mah, so a 10000mah power bank is able to charge it five or even six times.
Shell material and surface treatment
Another important aspect is the surface treatment and shell material.
When it comes to durability, it is important to make sure that the portable charger you are about to buy is strong enough to resist the abuse of daily use without putting in danger the charging element itself.
Cell Phone Power Banks: Pros and Cons of Using Power Banks
Since we are living in a fast-paced era, it is extremely important to be able to take care of our mobile phones’ needs. Sometimes it is practically impossible for us to feed full charge to our phones before leaving the house. What’s more, we often end up staying out for long hours and, during this time, our phone’s battery keeps shrinking and may end up running out of charge. This problem can be easily solved by simply having a power bank at hand. Power banks serve as the ideal tool that can rescue our phone during urgent moments. Having a backup battery and fitting it into our phones when the original batteries get exhausted may also be an alternative solution.
Below you can find the main pros and cons of using cell phone power banks:
Power banks are portable
In simple terms, power banks can be carried to the office or when on vacation. They do not require electric sockets. That means that you will be able to charge your phone when you are traveling, camping, or holidaying inside a forest. Their portability certainly helps us avoid those dreadful situations when the cell phones run out of life.
Power banks carry very high power
Since most of these devices carry a very high power, they can serve us multiple numbers of times. This basically means that we can get our phones charged on more than a single occasion. For example, if we are going on a trip over the weekend, a decent cell phone power bank will last during the entire trip.
Power banks charge universally
The best thing about power banks is that they act as universal chargers. This basically means that they are compatible with almost all types of mobile devices. We can charge virtually any type of phone that you may have, including Androids, a Blackberry and even iPhones. In addition, they work for all brands: from Samsung to Nokia or Motorola.
Power banks are priced reasonably
Since they usually come at more than reasonable prices, they will not put a lot of pressure on your wallet or bank account.
Power banks come with multiple sockets and allow multiple charging
The vast majority of power banks are endowed with multiple sockets that will allow you to plug in several mobile devices suimultaneously.
Power banks can be bulky
Though there are exceptions, some power banks can be a little bit bulky. They might be thick and have extra weight. That means that, when one is carrying them around, they may feel a little inconvenient, adding load to your purse or handbag.
Power banks come with USB cables
We are undoubtedly living in a wireless age. And, since these devices use a USB cable, it can be perceived as another small setback.
Sometimes, power banks are nothing but a frivolous expenditure
If someone does not travel a lot or if he or she does not regularly use his or her cell phone for official work, purchasing a power bank may be another frivolous expenditure. Though most people find power banks very useful, for some others power banks may simply not be worth their price.
All in all, it is true that cell phone power banks have their share of cons. However, in the current context, it is safe to assume that their advantages easily outweigh and outnumber their disadvantages. Therefore, it is advisable to think seriously about purchasing one.
Can Power banks be used on planes?
It depends on the power bank’s capacity in Wh (watt hours). However, the most commercially available power banks should be OK to use on planes. According to the IATA guidelines, power banks under 100Wh can be brought in cargo and on board if they are installed in the equipment. In the case of loose spare batteries, one can bring as many as he or she wants but only in carry-on, not in the hold. The same rule applies to 100-160Wh power banks, but users are restricted to only two spare loose batteries and not allowed to check in. According to the Dangerous Goods guidelines, power banks over 160Wh must be declared and packed in cargo. Though most airlines are currently following the IATA guidelines, you must keep in mind that these rules must be validated by the rules of each airline and airport.
Most battery manufacturers offer advice documents with their products. So make sure to carefully check them out before a flight.
