Not all modern gadget supports wireless charging. This solution can benefit the owners of Apple equipment, Samsung, Nokia, LG, HTC, Sony, Blackberry, Yotaphone and Huawei.
The device is charged by such an apparatus by utilizing the magnetic field generated by the coil. The device is activated after the installation of equipment at the surface of the structure.
How to choose a wireless charging
Since the first wireless charging is not passed so many years. Then it only supports mobile phones. Now there is a model for Notebook and tabletsSpecially designed for installation in the line of the car.
There were improved versions - portable and able to be charged via the cover.
When choosing a charging model must take into account the following factors:
- Device Type. Board, in the form of the stand, cover, built for cars. Universal model, suitable for any type of equipment: phone, laptop. Models for specific devices too much.
- Manufacturer technology. Not all companies producing electronics, suitable for wireless charges. Apple and Samsung - the leader in this field.
- Power Standard. Charging, working on «Qi» technology, and those that operate on the principle of «PMA». Not all equipment supports two simultaneous standard.
The market is divided into equipment, which is suitable either single version charging, or other. Their difference in wavelength. Range Qi - 100-205kHz, PMA -277-357.
- The technology works. Simple models of smartphones is charged on the spot. new generation version can be transferred.
important parameters
- Power. 5 W at a distance of 4 cm say moderate embodiment. High power model outputs 30 watts or more. Functional unit charges the technique is not located within 2 cm.
- Working hours. The median of 4 hours. The model works more 5 hours refers to the slow line charging.
- Energy efficiency. In standard zaryadok efficiency rate is 75- 80%.
- Security. Non-ionizing frequencies no harmful effects on human health.
secondary options
- Form design. In a circle, rectangle, with stand - model can be arbitrary. The choice depends on the preferences of the buyer.
- Dimensions. Rectangular solutions are compact. Round take a bag or jacket pocket more space.
- Colors. Classic shades allow the use of charging at home and in the office. On the bright, bold patterns are not as relevant as the plain and clean lines.
The main parameter - the time of charging operation. Model, which requires 100% charge your phone for more than 5 hours is considered to be ineffective.
As for versatility, which allows you to simultaneously connect and smartphones, and laptops, it is better to forget about it. The development of such models is not the priority of the producers, so their market is small, and those that are, are not so powerful.
It is better to buy 2 wireless chargers - one for the laptop, the other - for the phone.
