Wireless Charging for any Qi Enabled Device

Our latest product at Power4Laptops, is the Wireless USB Charger for Qi enabled devices.

ADP158A

Wirelessly charge any Qi enabled smartphone. With a sleek, ultra slim design the Wireless Charging Plate is a fantastic space saving way to charge your phone at your home, office or on the go. Designed for quick and intuitive charging, this Qi enabled charging power bank allows you to charge any Qi enabled smartphone without the mess of charging cables. Supports drop and go charging anywhere on the pad. The free positioning feature of the Plate allows for greater drop and go convenience, giving you the freedom to charge your device quickly without having to lock your device into an exact position. This provides peace of mind as no matter how your phone is placed on the pad, its battery will be charged successfully. Compatible with Qi charging adapters, the Wireless Charging Plate is manufactured to the Qi standard. Qi is the sign of interoperability between power transmitters and power receivers.

It's important to remember that with Wireless USB Chargers, any charger will charge any phone as long as it's Qi enabled.

What is Wireless Charging?
Qi Wireless Charging with a wireless energy transfer of up to 5 watt.

Qi (the Chinese word for “energy flow“, pronounced like the “chee“ in “cheese“) is the universal standard for wireless charging of battery opererated devices like cell phones, iPods, MP3 players and cameras.

The wireless power transfer occurs through electromagnetic induction. With inductive charging the required power reaches the device not through a traditional cable but rather wirelessly through the use of electromagnetic fields. The principle is very simple: the Qi Sender (Charging Station) transfers the required energy to the Qi receiver (the mobile phone).

What is the point of wireless charging?
The biggest advantage of Qi Wireless Charging technology is that cell phones and chargers from different manufactures are compatible. The only requirement is that both parts – the sender and the receiver – fulfil the Qi specifications.

Therefore, every Qi enabled device is compatible with every Qi charging transmitter, regardless of the manufacturer or make of the device. Numerous cell phones, including from market leaders like Nokia, Samsung, Sony, LG, Motorola and HTC,already comply with the Qi standard and can therefore be charged by any Qi Charging Station. The number of enabled devices is constantly growing as Qi wireless charging technology is integrated by an ever-expanding list of manufacturers. This allows you to charge your various battery operated electronic devices with just a single charging station.

How does Qi Wireless Charging work?
It’s based on the principle of induction

Wireless Charging isn’t really a completely new product. Electric toothbrushes have been using the principles of inductive charging for many years. Qi Wireless Charging uses a resonant inductive coupling between the sender (the charging station) and the reciever (the mobile device). A regular test signal is sent by the sender to check for a capacity or resonance change, telling the Qi enabled charger base that a qi compatible phone is present. The sender modulates the charge and checks for compatibility to the Qi standard.

Once Qi compatibility and the energy requirement have been calculated, the charging through induction begins. During the charging the sender and receiver remain in contact and switch into standby mode as soon as the battery is fully charged. Another advantage of the Qi charger base is that it only activates and transfers energy when an enabled device requiring charging is placed upon it.

With this technology the electromagnetic coils that send and receive the charge are especially shielded to reduce electromagnetic rays.

Is Wireless Charging worth it?
How convenient would it be to have a single charger for all your phones, iPods, MP3 players, cameras and not even need annoying cables?

As endless new smartphones cover the world battery running times have become shorter. Every make, sometimes even every device, has its own special charger. When you get a new device you need a new compatible charger. You quickly find yourself with a confusing pile of different chargers.

No more different chargers, no cable spaghetti, no empty batteries are only some of the advantages of wireless charging.

Qi as the global standard for inductive charging
Qi inductive charging is the global standard to wirelessly charge your phone batteries.

Do you remember the first time you heard of Wi-Fi or Bluetooth?

Just as Wi-Fi has become the global standard for wireless internet connections and Bluetooth; for handsfree, so will Qi become the global standard for inductive charging. Qi Standard is the future for cable free wireless charging for battery-operated devices for all.

How much electromagnetic radiation is emitted by the Qi Wireless Charging System?

Insignificantly little.

The principle of Qi has been used in electronic toothbrushes for years without any known physical effects on human health. Due to the low range of the Qi wireless charging technology, the electromagnetic radiation is severely limited.

Electromagnetic radiation exists only in the immediate area of the Qi wireless charging station and only when a device is placed there. The release of electromagnetic rays is further reduced by additional shielding in the sending and receiving coils of the Qi standard.

Wireless Power Consortium
The aim of introducing an international standard for Wireless Charging

The Wireless Power Consortium (WPC) was established on the 17th December 2008 and in the same year adopted Qi as the single standard for inductive charging. The introduction of Qi as the global standard enables universal inductive charging for all Qi compatible electronic devices.

That means that every Qi compatible device can be charged on every Qi compatible charging station. The Wireless Power Consortium, with 250 members including market leaders Samsung, Nokia, LG, Panasonic, HTC, Sony, Microsoft, Ikea and Motorola, is the biggest union of manufacturers for cable free, inductive charging.

“Due to the increase of Qi products, it is important to ensure that all wireless chargers work correctly with all mobile devices” says WPC Chairman Menno Treffers “the continually updated database created by Testronic makes it easy to determine whether a new product will be compatible with previously certified products.”

“In our view the introduction of the Qi Standard is one of the most important technical developments for users of mobile devices such as phones, tablets and other devices that are now used everyday in our work and private lives“ says Johan Craeyback, Chief Technology Officer at Testronic Labs.
