Transform Your Smartphone with Wireless Charging: Easy Upgrade Guide

Wireless charging is a highly convenient and practical feature, yet not all smartphones come equipped with it. Fortunately, adding this functionality to your favorite device is both simple and cost-effective. Here’s how you can upgrade your smartphone right now.

First, you'll need a wireless charging pad, commonly a small circular platform with a power input. For this example, we use an unbranded model featuring a stylish blue LED light. It operates from a 5V, 2A power adapter (standard USB) and connects via a microUSB port. The charger outputs 5V, 1A current, sufficient to charge most devices even during use.

The second essential component is the wireless charging receiver coil, which enables your smartphone to receive power wirelessly. Although the effective charging distance is minimal, the convenience of cable-free charging is significant. For example, you can integrate the charging pad into your car’s dashboard or place it on your bedside table—just set your phone down and relax without fumbling for cords.

There are numerous universal wireless charging receiver coils available on the market, compatible with various devices. Placement is key: the coil, often housed in a paper-like envelope, includes a microUSB connector (which can be modified to other connectors if needed). Note that the coil must be correctly oriented toward the charging pad for optimal operation. In some cases, you may need to open the envelope and flip the coil to ensure proper alignment, as the coil works only in one position relative to the charger.

Next, simply connect the receiver’s plug to your smartphone’s charging port, hide the coil under the phone’s case or back cover, and enjoy wireless charging.

Important: The charging pad requires a power supply that matches its specifications—typically 5V, 2A. Using a lower current adapter will result in slower charging speeds. To ensure proper performance, you may need to replace the charging cable with a high-quality USB cable capable of handling 2A current. Testing with a reliable power strip and quality cable confirms optimal voltage and current delivery, minimizing power loss through connections.
