The way we are using our smartphone in a daily routine; it’s crucial for us to keep our mobile phone battery charged all the time. It’s practically impossible to charge the device very often by staying glued to the wall charging plug. And most importantly, you can’t get the wall outlets everywhere. That’s why power bank is invented to fulfill the purpose of charging the device and now the only option. The power bank is now a secondary battery of your mobile device.
Since power bank has been becoming popular; many people are beginning to get confused that whether power bank can cause mobile phone battery damage or not. Does a power bank damage the smartphone battery? Is it true? How and Why?
As we all know, only the cheap and fake power bank can damage the mobile phone battery.
Power bank comprises of the battery cell, PCB and shell. Among these components, PCB is the most important part. The PCB quality directly affects the charging effect because PCB controls the voltage boost and drop. So, the PCB is fully designed to prevent issues such as overcharge, over-voltage, high temperature, short circuit protection etc. This is essential but this is not designed in the bad PCB.
No Trickle Charge:
Do you know that the whole phone battery charging process consists of 3 stages: rapid, continuous and trickle charging. First two stages do not cause harm to phone battery generally, but trickle charging can. This is a little current to charge even after the battery is full and so, the flow of electro is continuous. While most of the power banks have been disconnected when a battery is charged around 90 to 95% means it will never charge fully so never will enter the trickle charge.
Power Voltage Fluctuation:
Generally, smartphones need a wall charger that provides a voltage output of 5V. However, there are many power banks that don’t deliver 5V output even when it’s written on it. These power banks couldn’t distribute the voltage that is not required to charge the phone sometimes. It’s hard to identify that a power bank is real or fake. There are some mobile applications available in the market that indicates voltage level and AMP value.
So, you should buy power bank online which are genuine means you will not get disappointed in the future. Now, the wireless charger is also available to get your phone charged without connecting with the cable.
Always opt for branded electronics devices to avoid major damages in the future.
