Can Charge Anything And Multiple Devices

Some power banks are exceptionally powerful and have large capacities. This makes them possible to charge multiple devices at once. Some even allow laptops to be charged.

It serves as a decent substitute for your smartphone or laptop charger. Moreover, they are simple to use.

With a push of a button and plugging in a cable, your device starts to charge. Some even have fast charging capabilities.

Easy To Purchase

Power banks are relatively cheap. You don’t need a large amount of cash to purchase one. You can get them for as little as $10.

But, being relatively cheap doesn’t mean they are all of the good quality. Some have questionable quality and can even damage your phone.

You have to do your research well and read reviews. This prevents you from buying a low-quality power bank.

Disadvantages Of Power Bank

Even with their awesome benefits power banks certainly, do have their disadvantages.

Things Can Get Messy With The Wires

Being able to charge multiple devices at once is great. But, it becomes a real pain when there are so many wires connected.

Things become messy and tangled up. This causes an unpleasant sight. You can try it yourself. Just try charging multiple devices at once, put it in your bag and try to bring it out again.

The wires would be tangled up and you would be mildly annoyed. A good rule of the thumb is that, disconnect your device once it reaches 80-90 per cent of battery power.

There is no need to charge it to 100%. Because charging it from 90% to 100% is going to consume more power.

Once it is in that range simply disconnect the device and cable. This leads to fewer wires, devices and mess.

Some Have Questionable Quality

As mentioned above, power banks are relatively cheap to purchase. This also makes a lot of them have questionable quality. Poorly made power banks don’t last long because their build quality is subpar.

In addition, some are not able to charge your device but rather discharge it. Because their output voltage is lower than the recommended voltage to charge your phone.

Some even have high output voltages which can damage your phone battery. The damage is in the form of swelling. Always do your due research and read reviews.

Takes A Long Time To Charge

Because power banks have large capacities charging them takes a long time. Even more so if the power banks do not support fast charge. It will take even longer to charge if it is solar powered.

A typical 40000 mAH power bank with a 2V charger is going to take 20 hours for it to be completely charged.

The larger the capacity the more time it takes to charge. That’s the price paid for the benefits of owning a power bank.

Can Be Uncomfortable To Use

It was said earlier that power banks are easy to carry around. But that doesn’t mean they are comfortable to use.

Majority of the power banks are bulky. And all power banks are over an inch thick.

Some don’t even fit into your palm quite easily. The larger capacity ones are quite large.

Do Power Banks Reduce Battery Life?

No, power banks don’t reduce battery life. High and low temperatures reduce battery life. Battery age reduces battery life.

Lithium-ion batteries have charge and discharge cycles. Once the lithium-ion battery has gone through its number of cycles. The battery becomes weak and eventually useless.

In other words, the more mAh the power Bank has, the larger the energy is. Such as iPhone 6 Plus features a battery capacity of 2915mAh so if you would like to possess it fully charged, you ought to have an influence Bank with more mAh than your phone’s capacity.So if your device has a 5000mAh battery, then you can go for a Power bank with twice or thrice the capacity.

Keep on reading further for more about power banks, and what impact they have on your phone’s battery.


Types Of Power Banks:

Most of the power banks available in the market consist of two types. One consists of Lithium-ions cells, while the other contains Lithium-Polymer cells.

Lithium-ion cell power banks have a higher energy density and are cheaper than the other. However, power banks containing Lithium-ion cells lose their charging capacity over the duration they are used and are bulkier.

On the other hand, power banks with Lithium-Polymer are expensive, but they are safer, and unlike Lithium-ion, they don’t lose their actual charging capacity with time. They also take less time to charge.

Further, they are divided into three broad categories:

  1. Universal Power Bank

The most common ones, universal power banks come in various sizes and output variations and give the end consumer a wide range to choose the best one according to their requirements.

  1. Solar Charged Power Bank

These power banks contain photovoltaic panels which are charged through sunlight. This is then converted and used to charge electronic devices.

Although it’s an environmentally friendly device, it tends to take a lot of time to charge, and that too is limited to availability of enough sunlight.

  1. Battery Phone Case

These are compact and easiest to carry along. However, they have a very low variety available in term of devices.

So the next time you are considering buying a power bank, choose one based on the type which is more suitable for your requirements.

How To Choose The Best Power Bank For Your Phone:

There are some factors to consider before buying a power bank, include:

  • Capacity:

The capacity a power bank should always be more than the capacity your phone requires. For example, a 2200 mAh wouldn’t be able to fully charge a phone with a requirement of 3000 mAh. Likewise, a power bank with 6000 mAh would be able to charge your phone fully two times.

  • The Number Of Outputs:

Some power banks have 1 output outlet; some have 2, and so on. Choosing one depends on how many devices you would need to charge at the same time.

  • Output Specification:

How much output your phone needs should also synchronize with the output the power bank gives out. Ideally, the standard output should be 5V for phones. Any more, and it would damage the phone.

Advantages Of A Power Bank:

The main benefit of power bank is that they are great for charging phones on the go, or when there is no electricity available.

Aside from that, most power banks come with a large capacity, which makes them handy for charging your phone multiple times, without recharging it. And when the battery of the power bank does drain, they can be easily charged through laptops, car chargers, and wall sockets, whichever is more convenient.

Disadvantages Of A Power Bank:

Power banks come with their own share of disadvantages as well. Many of the power banks available are either bulky or expensive. Apart from that, they do require to be charged when their battery drains, and if their capacity is lower, then they drain faster.

They also impact the battery of a phone in some instances, as mentioned below.

Impact On Battery:

While it’s extremely rare for a power bank to damage the battery of a phone, there are some instances where it might happen.  Here are some cases where you might be damaging your phone’s battery with your power bank, and how to fix them:

  1. You Are Using A Bad Quality Power Bank

Quality is very important when choosing a power bank. A bad quality power bank can damage your phone’s battery, as well as your phone’s charging port. It can also create some security risks. For example, overcharging a bad quality Lithium-ion power bank can cause the power bank to explode.

  1. Your Power Bank Has The Wrong Voltage

Having the wrong voltage in your power bank will lead to problems. The ideal voltage to charge a phone is 5V. If any power bank gives a voltage of 4.2V or less, it will drain your battery instead of charging it.

Any voltage output greater than 5V will extensively damage your phone’s circuits by overloading it more than it can handle.

  1. You Are Overcharging:

Power banks should essentially be used sparingly. Using power banks to constantly keep your phone at 100% charge will over time damage the battery, which will lead to your phone not being able to retain its charge for long.

To avoid these problems, avoid using your power bank to overcharge your phone. Use it for emergencies, and even when you do use it avoid charging your phone up to 100%.

Along with that, buy your power banks from authorized retailers, and choose the highest quality of power bank, with the right requirements for your phone. Dealna.com has a wide variety of authentic, high-quality power banks:
