Power Banks: The effect they have on your Battery

Everyone that is always on their phones do one thing or the other sees power banks as a lifesaver. In this century, our cellphones contain our entire lives in it, be it a photographer’s photographs, to an entrepreneur’s documents. When you’re on the go most of the time, locating wall outlets everywhere to charge your phone when the battery drains is basically impossible. When your phone suddenly turns off when you need it most, a power bank prevents you from running into a downturn.

As you keep on reading this article you will understand more about power banks and the effects they have on our batteries.

What is a Power Bank?

Power banks can be described as portable batteries using circuitry to control any power input and power output. When power is available, they can charge up battery-powered products such as mobile phones and a host of other devices that would usually use a USB charger.

Types of Power Banks

Typically most of the power banks in markets are of two types; One consists of Lithium-ions cells, while the other contains Lithium-Polymer cells.

  • Lithium-ions cells: Lithium-ion batteries have a higher energy density, i.e. they can store more electrical charge in a given amount or volume, and they are cheaper to produce, but they may have problems with ageing.
  • Lithium-Polymer cells: Lithium-polymer power banks do not suffer as much from ageing as a better choice. Nonetheless, they are more expensive to manufacture and may not suit all budgets as a result. Sometimes it may be best to spend less, especially if they are likely to be lost or left in places accidentally.

These types of power banks can be further divided into the categories below:

  • Universal power bank: This is the most common, Universal power banks, come in different sizes and variations in production and offer a wide range to the end consumer to choose the best according to their needs.
  • Solar charged Power bank: These power banks are made up of photovoltaic panels charged by sunlight. This is then converted and used for charging electronic devices. Despite being an environmentally friendly device it appears to take a lot of time to load, and that too is limited to getting enough sunlight available.

Battery Phone Case: They are compact and easy to take with you. 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.

Choosing the best Power Bank for your Phone

When you are buying a power bank, here are the factors to put into consideration:

  • Capacity: One of the most important thingss to consider when buying or selecting a power bank is the capacity required. Think about what needs to be charged because a tablet takes more than a smartphone and so forth. Also some smartphones take more charge than others. To find out take a look at your smartphone specification. The battery capacity will be given under the battery area.

The capacity of your power bank must be more than the battery capacity of your phone. 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.

  • Power bank output charge current: When buying a power bank it’s also important to think about the rate at which it can deliver charge. This affects the charge time.

    The power banks will normally say what the current they are able to deliver. The lower it can provide the maximum current, the longer it takes to charge the device. Some bigger power banks have multiple outputs and each output is specified and written on the power bank often. Be mindful, however, that if a system has many inputs, it may not be able to deliver the full current at the same time to all outputs.

    So if you want quick charging times, then buy a high-output power bank. Do not worry if the phone or computer is unable to take the maximum current, it will only take what it can manage.

  • The Number of Output: Most power banks have 1 output; some have 2 output outlets, and so on. Choosing one depends on how many devices at the same time you need to load. Do note that if several devices are charged simultaneously, the power bank may not give each port the maximum current, an average maximum current output may be shared between the outputs, slowing down device charging.
  • How to charge the Power bank: It’s worth remembering that the power bank itself will have to be charged. The more power it takes, the longer it takes. If you only have a 1-amp adapter and the power bank has a capacity of 5000 mAh, it will take five hours to charge-well a little longer because not all the charges entering the power bank are converted into stored charges, there may be an efficiency factor of 80% or more, so it will take longer.

Note: The charge is measured in mAh simply means “milliamps per hour”.

Advantages of power bank

The main advantage of power bank is that they are useful for charging devices on -the-go, or when there is no electricity.

In addition, most power banks come with a large capacity, making them handy to charge your phone multiple times without recharging it. And when the power bank’s battery drains, it can easily be charged via laptops, car chargers, then wall sockets, whichever is more convenient.

Disadvantages of power bank

Power banks also come with their own share of downside. Many of the available power banks are either bulky or costly. Besides that, as their battery drains, they need to be charged, and when their power is smaller, they drain faster.

In some cases, as described below, they also affect a phone’s battery.

Effect of power bank on our phones

Though damaging a phone’s battery is extremely unlikely for a power bank, there are some occasions where this may happen. Here are some circumstances where the battery of your phone with your power bank could be fried and how to fix it:

  • Using a bad quality Power bank: When selecting a power bank, reliability is very critical. A bad quality power bank can damage the battery of your phone as well as the charging port of your phone. It can also create some safety hazards. For instance, overloading a Lithium-ion power bank of bad quality can cause the power bank to explode.
  • Power Banks with wrong Voltage: In your power bank, having the wrong voltage will cause problems. The ideal phone charging voltage is 5V. If any power bank has a 4.2V or less voltage, your battery will be drained instead of charged.
    Any voltage output greater than 5V, by overloading it more than it can handle, will damage the circuits of your phone extensively.
  • Overcharging: 

    Power banks should be used carefully in nature. Use power banks to keep your phone constantly at 100 percent charge will degrade the battery over time, which will result in your phone being unable to maintain its charge for a long time.

    Stop using your power bank to overcharge your smartphone to avoid these problems. Use it for emergencies and stop charging your mobile up to 100% and when you use it.
