How To Select A Wireless Charger For An IPhone X Or IPhone 8Aug 20, 2018

Technavio’s market research analyst predicts the global wireless charging market to grow at an impressive CAGR of more than 33% by 2020, indicating how important this space is set to become. This year has seen many changes in the wireless charging sector, some of which have been detailed below:


Charge anything, anytime, anywhere.

All electronic devices are united by the necessity to be charged. Currently, wireless charging is mainly used to recharge smartphones, a market that Samsung and Apple have already begun to explore and consolidate. This is validated by industry data that states that 55% of the wireless charging market share was accounted for by consumer applications.

In addition to this, wireless charging products still function as accessories that are subsidiaries to smartphones rather than being separate products by themselves. Research has identified certain major areas where users require their phones to be charged: at home, at their work desk, at restaurants and while travelling. By pinpointing prime charging environments, companies will now be able to streamline wireless charging technology and allow a more user-friendly experience.


There are tons of wireless charging options out there in the world, and finding one that’s actually good for your new iPhone can be confusing. So to help you get ready, we’ve put together a guide of what to look for in a wireless charger for your next iPhone.


1. Qi charging:

Qi is key. Wireless phone charging had been a mess because of multiple standards.Nobody would want to set a phone on a charger in an office, coffee shop, hotel or car and find out that it's incompatible. The industry now has mostly settled on one standard called Qi (pronounced "chee"). For example, the day after Apple announced in September that its new iPhones would use Qi, charging station maker Powermat announced that its wireless charging spots atStarbucks coffee shops would add compatibility with Qi.Samsung supports Qi in its Galaxy S8and Note 8 phones.Furniture giant Ikea sells lamps with Qi wireless charging stations built in,and outside the house, the standard is in some cars from Ford, Audi, BMW, Toyota, Honda, Chrysler, Hyundai and Volkswagen.


2. 7.5W of power

The one adopts the same fixed-frequency voltage regulation architecture of Apple’s 7.5W. With the MP-A11 topology, the operating frequency is fixed at about 127KHz, the duty cycle is constant at 50%, and the transmission power is controlled by adjusting the voltage. It can effectively avoid the frequency band that interferes with the mobile phone, so that the wireless charging can minimize the interference to the mobile phone. There is a Q-value detection circuit that will be more sensitive in terms of FOD detection and meet the requirements of the EPP.

3. Standard connector:

Most wireless charging pads plug in to an adapter of some kind to actually connect to a wall outlet. Some companies use weird proprietary jacks to plug in the pads, and others use standard ones like MicroUSB or USB-C. If you can, it’s probably better to go with a standard connector, just in case you damage or lose the cable. And while there aren’t any yet, it might be worth holding out for someone to make a Lighting-compatible charging pad so that you’ll be able to directly charge your phone with one cable, should you need to.

4. Wall Charger:

By the same vein, check to see if your charging pad actually comes with a wall adapter. If you’re expected to provide your own, make sure that it can provide enough wattage to charge at full speed — a 7.5W pad with a 5W wall jack will only charge at 5W.

5. Size and aesthetics:

There are a bunch of styles of wireless chargers, some big, some small, some flat, and some that charge your phone at an angle. Consider what you’d want on your desk or bedside table before buying.

6. Future proofing:

The iPhone 8 and iPhone X only support up to 7.5W for fast charging, but the latest Qi 1.2 standard actually offers up to 15W for compatible devices (like the Samsung Galaxy S8 and Note 8). So if you’re investing in wireless chargers, it might be worth looking out for a more powerful charger that will support future devices, should you change phones. As a note, getting a more powerful charger won’t hurt your lower rated devices — it’s similar to using an iPad charger to charge an old phone, where if the device can take advantage of the faster speeds, it will.

7. AirPower:

Lastly, you might just want to wait a bit. Apple showed off a new wireless charger, called AirPower, that’s set to launch sometime this year, which is expected to be able to charge an iPhone, Apple Watch Series 3, and AirPods simultaneously — typically, chargers can only power one device at a time. It’ll also use a Lightning cable for connectivity, which as mentioned before is useful for iPhone users. Plus, Apple is working with Qi to integrate AirPower features into the Qi standard.



Now new third-party chargers with similar functionality are launched in the market.
