|Frequently asked questions|
What is Qi wireless charging ?
Qi is the new universal standard for wireless charging of battery-powered devices such as mobile phones, iPods, MP3 players, cameras, etc.
The wireless energy transmission is based on electromagnetic induction. With inductive energy transmission, the energy required by electronic devices is not transmitted via cable but wirelessly via electromagnetic fields. The principle is very simple: the Qi transmitter (charging station) transfers the required energy to the Qi receiver (the mobile phone).
Why the wireless charging?
The biggest advantage of Qi wireless charging technology is that mobile phones and chargers from different manufacturers are compatible. The only requirement is that both devices, the transmitter and the receiver, comply with Qi specifications.
In this way, any Qi-compatible device can be charged on a Qi-compatible charging station, regardless of the manufacturer or brand of the devices.
Many mobile phones, including those from market-leading brands such as Iphone 8, Iphone X, Nokia, Samsung, Sony, LG, Motorola and HTC, are already Qi-compatible and can therefore be charged on any Qi charging station. More and more manufacturers are integrating Qi into their electronic devices, which allows them to charge different electronic devices with one charging station without having different charging stations.
How Qi wireless charging works ?
Induction charging, wireless charging in the true sense of the word, is not a completely new product. Electric toothbrushes have been working for years with the principle of inductive charging.
Qi wireless charging uses an inductive resonant coupling between the transmitter (charging station) and the receiver (mobile phone).
The transmitter produces a regular check signal, which recognises by the electromagnetic frequency whether a device to be charged is on the Qi wireless charging station. The transmitter modulates the charging process and checks for compatibility with the Qi standard.
Once the Qi compatibility and the required energy have been calculated, the inductive charging starts. During charging, the transmitter and receiver remain in contact and go into standby mode once the battery is fully charged.
Another advantage of the Qi charger is that it only switches on and transfers energy if a compatible device that needs charging is placed on it.
Thanks to this technology and a very good isolation of the transmitting and receiving coil, the electromagnetic radiation is basically reduced.
Is wireless charging useful ?
An infinite number of smartphones are available worldwide and battery life has become shorter. Each brand, and even each device, has its own charger. Every time you buy a new device, you need a new compatible charger. You soon find yourself with an unimaginable number of different chargers.
Wouldn't it be easier to have one charger for all your phones, iPods, MP3 players, cameras and not need those annoying cables?
Too good to be true?
Not with Qinside wireless induction charging stations!
Imagine one Qi wireless charging station for all your Qi enabled phones. Forget all the different chargers and the tangle of cables and share one charger at home, in the office or on the move.
Imagine lounges, waiting rooms, airports, train stations, bars and restaurants with Qi charging stations built into the furniture.
You can charge your devices whenever you want, regardless of the model, brand or manufacturer of your device.
The only requirement is that you have a Qi-compatible device or use the Qi2001 receiver for iPhone 4, iPhone 4s and all phones with micro-USB connection or use our Qi charging case for iPhone 5, iPhone 6 and iPhone 6+.
Fast and easy: charge your devices with up to 10 watts of wireless power transfer.
Empty batteries in mobile phones, iPods, MP3 players and cameras will be a thing of the past!
Qi, the international standard for induction charging?
Do you remember the first time you heard about Wi-FiTMorBluetooth®?
Just as Wi-FiTM became the international standard for wireless internet connections and Bluetooth® for hands-free, Qi will become the international standard for inductive charging. Qi is the future of wireless charging for battery-powered devices for everyone.
What is the extent of electromagnetic radiation from Qi wireless charging systems?
Minimal. The Qi principle has been used in electronic toothbrushes for years, with no known physical effects on human health. Due to the short range of the Qi wireless charging technology, the electromagnetic radiation is very limited. The electromagnetic radiation has a low radiation around the Qi charging station and only when a device is placed on the charging station.
Thanks to the additional isolation of the Qi standard transmission and transmission coil, the emitted electromagnetic radiation is reduced.
Why is there an international standard for wireless charging?
Founded on 17 December 2008, the Wireless Power Consortium (WPC) adopted the Qi standard for inductive charging in the same year. The introduction of the Qi global standard allows universal inductive charging of all Qi-compatible electronic devices.
This means that any Qi-compatible device can be charged at any Qi-compatible charging station. The Wireless Power Consortium currently has 250 members, including market leaders such as Samsung, Nokia, LG, Panasonic, HTC, Sony and Motorola, the largest union for wireless inductive charging.
According to WPC chairman Menno Treffers, with the rise of Qi products, it is essential to ensure that all wireless chargers work properly with all mobile devices. Testronic's regularly updated database of Qi-compliant products makes it easy to check whether a new product works with all previously certified products.
According to Johan Craeybecks, CTO of Testronic Labs, "We believe that the introduction of the Qi standard is one of the most important technical developments for users of mobile devices such as laptops, tablets or other devices, which are nowadays part of our daily business or private lives."
Can you charge several phones on one Qi1001 charger?
No, the charging capacity of a Qi charger is only suitable for one device.
