Do you need practical and fast charging? Magnetic power banks are the answer. Using these power banks will enhance your wireless charging experience.
This article will discuss magnetic power banks, from their definition, how they work, their benefits, and usage regulations.
What is a Magnetic Powerbank?
A magnetic power bank is a type of wireless power bank. With this device, you won’t have to deal with messy cables when charging your device.
Simply place your smartphone on the power bank, and charging will begin automatically. Through magnetic induction, the power bank can transfer power to the device you place on it.
How Does it Work?
In principle, magnetic power banks work based on electromagnetic induction. There are two important components in how this device works, namely the transmitter coil in the power bank and the receiver coil in other devices.
- The transmitter coil generates an electromagnetic field: The transmitter coil in the power bank generates an electromagnetic field when electricity flows through it.
- The receiver coil converts electrical current: The receiver coil in the device converts the electromagnetic field into electrical energy to charge the battery.
An important consideration when charging with this device is the position of the coils; if they are misaligned, it can slow down the charging process or even cause it to fail.
The Features
The main function of a magnetic power bank is to provide a wireless audio listening experience. Here are some of the functions:
- Large battery capacity: Capacities range from 5,000 mAh to 10,000 mAh.
- Safety features: Foreign object detection (FOD) and thermal control.
- Dual-device charging: Some models allow simultaneous wireless and wired charging.
- Snap-to-Charge & MagSafe: Strong integrated magnets ensure the power bank adheres precisely to your phone.
- Built-in Kickstand: Equipped with a foldable kickstand, it allows you to prop your phone up vertically or horizontally while charging.
The Benefits
Using a magnetic power bank offers many benefits, especially for wireless charging. Here are some of the main benefits:
1. Wireless charging
The main benefit of a magnetic power bank is wireless charging. With its magnetic feature, the power bank can be charged simply by attaching it to the device.
You don’t need to plug a cable into the power bank or the device. The phone attached to the power bank automatically charges.
2. Compact design
Another benefit of this power bank is its compact design. This is unlike conventional power banks, which are generally larger in size depending on their charging capacity.
The compact design makes this magnetic power bank lighter, making it very easy and convenient to carry when traveling.
3. Enhanced convenience
Convenience is one of the things we look for when using anything. This is also what a magnetic power bank offers. That’s why it’s designed to be cordless.
You won’t be bothered by tangled cables or searching for a power outlet to charge your device.
This certainly increases your convenience when using your smartphone while charging.
4. Reduced port wear
Reduced port wear is another advantage of this power bank. Wireless charging reduces the risk of damage to your smartphone’s physical charging port.
This is because you don’t have to regularly plug and unplug the cable from your smartphone’s port. This means your phone will last longer.
How Safe Is It?
One of the questions often raised when new technological innovations emerge is the safety of their use. This is the case with magnetic power banks, which use electromagnetic fields.
Most people worry about their use impacting their health or other electronics. What you need to know is that every device that uses radio frequency (RF) goes through a testing process.
This is to ensure that the device meets international standards, ensuring it doesn’t harm your health or other electronic devices.
Therefore, it’s important to choose products from trusted brands with clear certifications. You can generally find the certification on the label affixed to the packaging or device.
Usage Regulations
Magnetic power bank technology operates within a specific frequency spectrum. In each country, all Wireless Power Transmission (WPT)-based wireless devices must have a Type Approval Certificate.
Wireless regulations require all radio frequency-based devices to meet specific technical standards before they can be sold in that country. This certification ensures that the product meets safety standards and does not interfere with other communication devices.
The certification process involves technical testing, including frequency tuning, safety checks, and environmental compatibility verification. Ultimately, this results in a Test Report confirming that the product meets technical standards and is safe for use.
For companies wishing to sell magnetic power bank products, Dimulti, as a Type Approval Service, can assist with this process. Our services include preparing technical and legal documents, conducting necessary testing, ensuring compliance with national regulations, and helping companies streamline the certification process.
