Buyer's Guide

How to choose the best Qi Wireless Charger

What are Qi Wireless Charger?

Qi wireless charger is a charging pad used for smartphones and other mobile devices. The device works using inductive coupling, so there's no direct connection between the charging mat and the phone. The only thing connecting them is the magnetic field generated by coils inside the two devices.

Advantages of Qi Wireless Chargers

  • Portable: Qi wireless chargers are portable, meaning they don't occupy too much space and can be easily moved from place to place.
  • Wireless: There is no wire involved, making it safe for use around children and pets.
  • Long Lasting: Because there is no direct physical connection between the charging pad and the smartphone, there is less wear and tear on both parts.
  • Recharge Time: Depending on the model, it takes about 30 minutes to charge up to 5% battery capacity.

Disadvantages of Qi Wireless Chargers

  • Power Consumption: When compared to standard wall outlets, Qi wireless chargers tend to consume more power.
  • Price: Compared to conventional wall outlet chargers, Qi wireless chargers cost more.
  • Noise Level: Some models emit noise while charging, but if you're looking for something portable, then you might consider it worth the tradeoff.

The Importance of A Purchasing a Quality Qi Wireless Charger

As wireless charging becomes increasingly popular, so do the number of devices that support it. But while we may all agree that it's great to have a compatible device, there are other factors that come into play.

1. Ease of Use

A quality charger doesn't necessarily mean it has a large screen; sometimes the best chargers don't look very pretty at all. What matters is how easily they can be used. For example, if you're planning to use a Qi wireless charger for multiple devices (such as smartphones), it might make sense to invest in a model that supports fast charge.

2. Safety

If you plan to leave your Qi wireless charger plugged in overnight, you'll want to ensure that it's protected against accidental damage. Also, avoid placing your wireless charger near electrical outlets, since this could lead to overheating issues.

3. Portability

Some Qi wireless chargers are bulky and heavy, making them difficult to carry around. While weight isn't always a concern, portability certainly is. After all, you wouldn't want to lug your smartphone charger around town, would you?

Features To Consider Before Buying Qi Wireless Charger

When shopping for wireless chargers, there are many features to consider. Here's a quick guide to get you started.

Wireless Power Transfer Technology (WPT) vs Magnetic Resonance Force Microscopy (MRFM)

Magnetic resonance force microscopy (MRFM) uses magnetic fields to generate a tiny oscillating current inside a superconducting coil. The generated AC current induces a voltage across the sample placed between the coil and ground. The resulting voltage is amplified and measured using a lock-in amplifier. MRFM allows for imaging samples down to nanoscale resolution, but requires extremely sensitive equipment and a very clean laboratory environment.

Capacitively Coupled WPT vs Inductive WPT

Induction coupling involves two coils. One coil acts as transmitter while the other serves as receiver. The alternating currents flowing in each coil induce voltages at their respective terminals. These induced voltages add up coherently if they are close enough together.

Advantages & Disadvantages of Capacitive vs Inductive Coupling

Advantages of capacitive coupling include lower cost, smaller size, higher efficiency, less heat generation, easier alignment, faster charging speed, longer battery life, and better compatibility with existing devices.

Disadvantages of capacitive coupling include low power transfer rate, limited operating temperature range, and reduced sensitivity compared to inductive coupling.

Considerations When Choosing Between QI/PMA Certified vs Non-Certified Products

QI/PMA certified products use a specific type of antenna design called a planar inverted F antenna (PIFA). They're designed specifically for wireless charging and offer a number of advantages over non-certified antennas such as greater efficiency, improved performance under various conditions, and lower SAR levels.

Non-certified products may also claim to be QI/PMA certified, but do not actually meet the requirements of the standard. Make sure you understand how your device works before purchasing.

Popular Qi Wireless Chargerbrands

A quick overview of Qi wireless charging brands

Qi

Qi has been popular since its inception in 2009. Its wireless charging standard was created in 2007 and first launched in 2010. Qi standards are based on resonance between two coils, one coil is connected to a power source while the other is attached to a device to charge. The advantage of Qi over other standards such as inductive chargers is that it's cheaper and easier to implement than inductive charging. The downside is that there aren't many compatible devices out there at present.

Powermat

Powermat was founded in 2008 and released its first products in 2011. Powermat uses magnetic induction to transfer energy from a transmitter to a receiver without direct physical connection. While the range is short (around 10cm), the convenience factor makes up for it.

Samsung LevelUp

Samsung LevelUp is a brand under Samsung Electronics Co., Ltd. The company first announced the launch of LevelUp back in 2015. LevelUp supports both Qi and PMA wireless charging technologies and offers compatibility with several smartphones and tablets. Samsung also claims that LevelUp can charge a smartphone twice as fast as normal wireless charging speeds.
