Quick answer: our top pick is Anker MagGo Qi2 15 W Pad (Qi2 · 15 W · pad).
What is a wireless charger?
A wireless charger is a device that enables inductive phone charging without cables. This technology uses the Qi Wireless Charging standard, which allows wireless power transfer via electromagnetic induction. It is a common solution among iPhone users, Samsung Galaxy smartphones, and many other devices.
Fun fact: The name of the Qi standard (pronounced "chee") comes from the Chinese word qì, meaning vital energy, and the first version of this standard appeared in 2010.
How does a wireless charger work?
The charger generates an electromagnetic field that is captured by a receiver coil in the phone. Alternating current is converted into direct current, which charges the device's battery. The main components of this process are:
- A transmitter built into the charger that generates an electromagnetic field,
- A receiver in the phone that receives energy and converts it into direct current.
Types of wireless chargers
Various forms of charging devices are available on the market, tailored to specific applications: a traditional pad lying on a tabletop, a stand allowing you to view the screen, 2-in-1 and 3-in-1 multi-device stations, and car mounts.
1. Stationary chargers
Most commonly used in homes and offices, these pads or stands often come in the form of multi-device stations allowing simultaneous power delivery to a phone, watch, and headphones.

What to look for when choosing a wireless charger?
- Charging standard: regular Qi (limited to 7.5 W on iPhones), Qi2 with magnets offering 15 W, and the latest Qi2.2 providing up to 25 W (for iPhone 16 and newer).
- Device power: a higher charger wattage will not speed up phone charging beyond its factory limit (for example, iPhone 15 wirelessly accepts a maximum of 15 W).
- Wall adapter power: to achieve full power, an induction charger requires a suitable adapter (for example, 25 W charging usually requires a power adapter of 30 W or more).
- Form factor: choices include flat pads, stands, 2-in-1 and 3-in-1 stations, and car mounts.
- Certifications and safety: thermal protection to prevent phone overheating and foreign object detection for metal items.
Fun fact: The modern Qi2 standard was developed directly based on Apple's MagSafe technology, using precise magnetic alignment to increase charging efficiency.
How to use a wireless charger?
- Connect the wireless charger to an appropriate power adapter.
- Place the phone centrally on the charger surface or align the magnets.
- Make sure the phone indicates that charging has started.
- Remove metal plates and payment cards from the case so they do not interfere with the electromagnetic field.
Frequently Asked Questions (FAQ)
1. Which phones are compatible with a wireless charger?
Most modern high-end and mid-range models, including iPhone 15, iPhone 16 Pro, or Samsung Galaxy S24 Ultra, feature a built-in induction coil.
2. How fast does an induction charger work?
Speed depends on the supported standard. Regular Qi chargers offer 7.5 W for iPhones, Qi2 accessories charge at 15 W, and the Qi2.2 standard allows up to 25 W with a compatible phone (e.g., iPhone 16).
3. Does an induction charger consume more energy than a wired one?
Yes, wireless charging involves energy loss generated as heat, making power consumption slightly higher than with a cable.
4. Does an induction charger work through a case?
Yes, as long as the case is not too thick and does not contain metal elements. For magnetic chargers, cases with built-in magnets provide the best results.
5. Will a third-party wireless charger charge an iPhone?
Yes, the Qi and Qi2 standards are universal. A universal charger will charge both an Apple smartphone and an Android phone that supports this standard.
Summary
An induction charger is a convenient solution that eliminates the need to plug a cable into your phone's port every time. When choosing one, matching the right standard (Qi, Qi2, or Qi2.2) to your smartphone's capabilities and connecting a power adapter with the proper wattage is key.
