Wireless charging devices are ubiquitous in modern daily life. Devices supporting wireless charging, such as smartphones, tablets, smartwatches, and Bluetooth earbuds, can all achieve "wireless" charging through wireless charging pads or power banks that support wireless charging. This article will introduce three common wireless charging standards: Qi, Qi2, and MagSafe.
&nbsp;
Qi is a standard established by the Wireless Power Consortium (WPC). However, Qi's drawback is that the device being charged needs precise alignment with the charging pad to achieve optimal charging efficiency.
&nbsp;
To solve the alignment problem, Apple introduced MagSafe, a magnetic wireless charging standard designed for the iPhone. Through its magnetic design, iPhones can easily align precisely for the best wireless charging experience. Apple also defined the MFM (Made For MagSafe) certification standard, allowing consumers to get up to 15W wireless charging for their iPhones using MFM-certified products.
&nbsp;
MFM-certified products are relatively expensive, while non-MFM certified wireless charging products can only provide 7.5W charging power. With the iPhone 15 announcing support for the Qi2 magnetic wireless charging standard launched by the WPC in 2023, consumers' choices are no longer limited to MFM-certified products. Qi2-supported products are also more affordable compared to MFM-certified ones and are compatible with both Apple and Android devices.

*Requires MFM certification to support up to 15W.
&nbsp;

Pros：
<ul>
<li>No charging cable needed, clean and aesthetic: Eliminates the need for a cable during charging, offering a clean, aesthetic, and convenient experience.</li>
<li>Magnetic design, stable and convenient: Attaches directly to the back of the phone, making it super convenient to use while charging.</li>
<li>Portable: Usually designed to be compact and fit snugly against the phone.</li>
</ul>
&nbsp;
Cons：
<ul>
<li>Charging speed still slower than wired fast charging: Maximum charging power is 15W, which is still slower than fast charging cables.</li>
<li>Limited compatibility: Primarily designed for devices with magnetic capabilities; non-compatible phones require an additional magnetic ring.</li>
<li>Heating issues: Can still generate heat during charging.</li>
<li>Higher price: Generally more expensive than standard wireless or wired power banks.</li>
</ul>

Requires MFM certification to support up to 15W

Currently, magnetic wireless charging devices on the market mainly fall into two types:
&nbsp;
Wireless Charging Pads (Suitable for indoor use)
Wireless charging pads need to be connected to a power outlet, making them suitable for use on desks or nightstands. However, they still require a charger and cable to connect to the power source, only reducing the cable requirement for the phone itself, and typically can only charge a single device.
&nbsp;
Power Bank + Magnetic Charging (Suitable for carrying around)
<a href="https://www.adata.com/en/consumer/category/power-banks/power-bank-r050-magnetic/" target="_blank" rel="noopener">The ADATA R050</a> and <a href="https://www.adata.com/en/consumer/category/power-banks/power-bank-r100-magnetic/" target="_blank" rel="noopener">R100</a> Magnetic Power Bank combine power bank and wireless charging functions, freeing you from outlet constraints and truly achieving "wireless charging freedom." These two products are designed for devices supporting wireless charging, offering magnetic wireless charging with a maximum output power of 15W. Additionally, to enhance usability, they feature a specially designed foldable kickstand, allowing them to serve not only as a power bank but also as a phone stand, meeting diverse usage needs. The <a href="https://www.adata.com/en/consumer/category/power-banks/power-bank-r100-magnetic/" target="_blank" rel="noopener">R100</a> is further equipped with USB-C and USB-A interfaces to charge multiple devices simultaneously, perfectly fitting the multiple digital life needs of modern consumers.
