If you're tired of cables cluttering your desk or bedside table and are looking for an elegant and efficient solution to charge your smartphone, wireless charging technology is the ideal alternative. With the proliferation of compatible devices and an ever-increasing variety of brands, models, and formats, choosing the right wireless charger can make a noticeable difference in your daily usage experience.
In this detailed guide, you'll discover all the essential and advanced information about wireless chargers: what they are, how they work, the advantages they offer over conventional chargers, the different standards and models on the market, purchasing advice, and a comprehensive analysis of the best wireless chargers for mobile phones available.
What is a wireless mobile charger and how does it work?
A wireless mobile charger is an accessory that allows you to recharge your smartphone's battery without the need for direct cables. The key to this technology lies in the electromagnetic induction: Both devices, the charger and the mobile phone, integrate induction coils that, when they come into contact or are placed at a very short distance, allow for efficient and safe energy transfer.
The most widely used standard today is Qi (pronounced 'chi'), adopted by most mid-range and high-end phone manufacturers, and guarantees compatibility and charging safety. When you place your compatible phone on a Qi-compatible base, the energy is transmitted through electromagnetic fields without the need to plug any cables into the device.
In practice, wireless charging is "contact" or "proximity" charging, as the phone must be placed on the base or dock for the process to begin. Some experimental chargers, such as WattUp or Cota, allow charging from several meters away, but these systems are not widely used and, in many cases, are quite slow compared to Qi.
Advantages of wireless chargers over traditional chargers
The main advantage of opting for a wireless charger lies in the elimination of visible cables and reducing clutter both at home and in the office. However, the benefits go far beyond:
- Simplification and convenience: Simply place your phone on the charging base to recharge the battery, without having to search for or plug in any connectors.
- Savings on charging port wear: The USB or Lightning connector suffers less wear and tear and is prone to breakdowns.
- Multiple charge: Many models allow you to charge two or more devices at once, such as compatible mobile phones, wireless headphones, or smartwatches.
- Greater safety during charging: Certified wireless chargers typically offer protection against overheating, overcharging, and short circuits.
- Variety of designs: You can choose from flat bases, vertical stands, mats, and 3-in-1 chargers to charge multiple gadgets simultaneously.
These chargers, thanks to induction technology, are especially useful for those who want to keep their desks clear and seek a faster and easier experience when charging their devices, reducing the number of cables in the room.
Why don't all phones include wireless charging?
The presence of wireless charging in mobile phones depends fundamentally on cost issues on the part of manufacturersIncluding Qi technology involves incorporating additional components – primarily the receiving coil and associated circuitry – which increases production costs, especially in budget models.
Furthermore, many mobile phone manufacturers choose to remove the wireless charging pad from the box as a standard accessory to reduce the final price of the device, leaving the purchase of the charger as an optional choice for the user.
The price of a wireless charger It is usually higher than that of a traditional charger: while a conventional charger can be purchased at very low prices, a quality certified Qi charger starts at a higher price, although its cost has been significantly reduced and offers can be found throughout the year.
Standards and compatibility: Qi, PMA and other wireless charging systems
While Qi is the most common and widespread wireless charging standard, there are other systems that coexist on the market:
- Qi: Universal standard adopted by most compatible Android and iPhone phones. It uses electromagnetic induction and requires contact or close proximity between the charger and the phone.
- PMA (Power Matters Alliance, also known as AirFuel): Similar to Qi in operation, it uses magnetic resonance and sometimes allows greater distance, but is less efficient. It's used in some devices and accessories, but its use is declining compared to Qi.
- Fast Wireless Charging: Samsung's Qi-powered technology is typically compatible with the brand's high-end models and other Qi-enabled phones.
- WattUp and Cota: They allow devices to be charged from a distance – up to five or ten meters respectively – although with very low power (1W in some cases) and are not very applicable, for the moment, for home users.
In the vast majority of cases, If your phone has wireless charging, it will be Qi compatible., so you'll just need to look for a Qi-certified charger to ensure compatibility and adequate charging speed.
How Fast Is Wireless Charging: Power Ratings and Key Tips
The charging speed of a wireless charger depends on two main factors: the charger output power and mobile reception capacityThe Qi standard allows for power outputs of up to 15W, although some models and brands, such as Xiaomi and Samsung, offer power outputs of up to 20W or more on their high-end devices.
For most users, the most widespread power on the market is 5 to 10W (enough to charge overnight or on your desk), although the best wireless chargers for mobile phones offer 15W, and some reach 20W or more. It's important to note that your phone must support that power to take advantage of fast charging.
- 5W: Suitable for slow charging throughout the day or night.
- 7,5W: Compatible with recent iPhones and some Androids.
- 10W: Common power in mid-range and high-end Androids.
- 15W/20W or more: For the latest generation of mobile phones and ultra-fast charging.
Designs and types of wireless chargers for mobile phones
Wireless chargers come in a variety of formats, each designed for different needs and spaces:
- Flat bases: Simple, compact, and affordable. They allow you to place your phone in any position, although they don't make it easy to view the screen while charging.
- Vertical Docks: Stands that hold your phone in a vertical or horizontal position, allowing you to view notifications, videos, or make video calls while charging.
- Mats: They offer space to charge multiple devices at once, such as your phone, headphones, and smartwatch.
- Car chargers: Holders that keep your phone secure and charging while traveling, ideal for GPS navigation and hands-free calling.
- 3-in-1 and 2-in-1 chargers: They integrate multiple charging zones specifically for mobile phones, smartwatches, and headphones, optimizing space.
Each type has advantages and disadvantages depending on your priorities: bases and docks offer faster charging speeds, mats allow greater flexibility, and vertical designs make it easier to interact with your phone while it charges.

Key aspects to choose the best wireless charger for your mobile phone
To choose the most suitable wireless charger for your phone and needs, it's a good idea to consider the following factors:
- Compatibility: Make sure the charger is Qi-compatible and supports the maximum power your phone accepts.
- Charging power: Choose 10W, 15W, or higher models if you're looking for fast charging. If you prioritize economy or will be using it overnight, 5W models may be sufficient.
- Design and size: Consider whether you prefer a flat base, vertical dock, mat, or multi-charger, and whether the available space accommodates that format.
- Safety certifications: Look for certified chargers (Qi, CE, FCC), with protections against overheating, short circuits, foreign object detection, and automatic shut-off.
- Case Compatibility: Most Qi chargers will charge through cases up to 5mm thick, but metal or very thick cases can cause issues.
- Accesorios incluidos: Some models only include a base and cable (no power adapter), while others come with everything you need for fast charging.
- LED lighting: Choose chargers with discreet LED indicators if you'll be using them on your nightstand, avoiding bright or distracting lights.
- Value for money: The price difference may be justified by the power, quality of materials, or extra features such as dual or triple charging.
