Sit back and let’s explore everything related to advanced power banks.
What Are Power Banks?
Nowadays, everyone owns a power bank. Well, not everyone but it is guaranteed that everyone is well aware of this advanced gadget. Besides knowing this advanced gadget, every mobile owner knows its purpose and how to use it. Well, if you are still unaware of power banks, then no worries, we have got you. Let’s briefly discuss what a power bank is.
A portable Charger or Power Bank is a battery-based compacted equipment. that is specifically aimed to recharge numerous electronic equipment including smartphones, tablets, etc when the traditional power is not available. A power bank stores electrical energy in the form of chemical energy which is later converted into electrical energy.
History of Power Banks
Power banks were introduced in this world in the early 2000s. However, various types of modifications are now made in advanced power banks. At first, it was an accessory that was used to charge tablets and mobile phones in the absence of traditional electricity. But now, modern power banks are equipped with advanced features like compact design, indicating lights, etc.
The initial conception of power banks was at the Las Vegas International Consumer Electronics Show in 2001. At first, it was nothing more than a control circuit and AA batteries assembled by some college students. The earlier power banks have a large size and a short life.
The first power bank in the market was launched by Huaqi. The development of management circuits, applicable batteries, integrated circuits, and other technology made the power bank more innovative, and slowly the power bank industry began to develop.
How Power Banks Gained Popularity?
Power banks gained popularity after the introduction of iphones. The earlier iPhone models had a poor battery that could last only 4 hours. This leads to a massive increase in the demand for premium power banks.
How Power Banks Work?
Before discussing how a power bank works, it is important to note down its important parts. A power bank consists of a portable battery, mainly a lithium battery, a connector, a motherboard, and a PCB (PCB stands for Printed Circuit Board). PCB serves as a connection and support between various components that make up a power bank. A battery protector is also employed in premium power banks. Its main function is to protect the battery from degrading or damaging the lifetime due to over-charge, over-discharge, and overcurrent.
A power bank works by storing the electrical energy in the installed batteries. The stored current can later be used to charge electronic equipment including mobile phones, laptops, tablets as well as other portable gadgets. We have divided the working of the power bank into 3 stages.
Input Stage
The input stage is also known as charging the power bank. In order to use a power bank, we have to charge it first. This can be done by connecting the power bank to any external power source including a wall outlet or a computer’s USB port. All power banks contain a circuit that helps regulate the incoming current and voltage to safely charge the internal battery. Also, such installed circuits avoid overcharging.
Storing Energy
Once we connect the power bank to any electricity source, the battery starts storing the charge in chemical form. The chemical energy can be converted back into electrical energy when needed. The storage capacity of the power bank is measured in mAh (mAh stands for milliampere-hours) or Wh (watt-hour). This unit indicates how much charge the power bank can hold.
Output Stage
As suggested by name, after energy is stored and batteries are fully charged, here comes the output stage. You can charge any portable device (for example, mobile phone, tablet, etc.) via a USB port or other compatible output source. A voltage regulator is present in power banks that help in determining whether the output voltage is stable and appropriate for the gadget or device being charged.
After that, the power is transformed from chemical energy into electrical energy. Various types of protection circuits including short-circuit protection, over-discharge protection, as well as temperature control sensors are employed in premium power banks. Such sensors are crucial for protecting both the device and the power bank.
Which Types of Batteries Are Used in Premium Power Banks?
As technology is progressing rapidly towards advancement, various types of batteries are used for various purposes. The most commonly used batteries in premium power banks include the following:
Li-ion Batteries
Li-ion or Lithium-ion batteries are widely used in power banks. They are lightweight and are known for their excellent performance. Besides being highly durable, they have excellent energy density. Li-ion batteries have a nominal voltage of 3.7V per cell.
LiPo Batteries
LiPo or Lithium Polymer are the best batteries that are gaining popularity these days. Why? Because they are highly safe, more flexible in shape and size, and less prone to leakage or damage. Only highly professional companies install LiPo batteries in their high-quality power banks. Just like Li-ion batteries, they have a nominal voltage of 3.7 V per cell.
NiMH Batteries
Besides Li-ion and LiPo batteries, NiMH batteries are also used in power banks. However, their use is limited. And they are not widely used in modern power banks. They have a longer life cycle and are considered environmentally friendly. Their use is limited because they can self-discharge rapidly.
Are Power Banks Safe?
When used appropriately and handled with care, it’s a big YES. But their safety depends on numerous factors including usage, quality, as well as storage. If you are buying a power bank, make sure it is certified. Always choose power banks from reputable companies that comply with safety standards including FCC, CE, etc. Always stick with usage guidelines. Avoid overcharging the power bank and ensure the power bank’s current and output voltage are compatible with your smartphone or other devices.
