100% Brand new
Wireless power supply technology can make the receiving end through the air, paper or plastic shell, etc can achieve power transmission, it greatly convenient application, this technology is the latest to get the breakthrough development and practical application in step by step. Our wireless power supply using "magnetic coupling resonance" the new technology of electric power consumed only traditional electromagnetic induction power supply technology of one over one million, when transmitting terminal power on, it will not outward emit electromagnetic waves, but only in the forms around a non radiation field. The magnetic field is used to and receiving end contact, excitation receiving end resonance, thus to small consumption for price to transfer energy. In this technology, the strength of the magnetic field will but and the earth's magnetic field intensity similarity, people don't have to worry about the technology of the body and other equipment adverse effects. Receiving coil choose emission coil the same size number of turns winding, in determining the distance adjustment of coil turns to receive voltage a little higher than load is preferred. Receiving coil output is high frequency ac voltage, can be directly to small bulb power supply, to other electric power supply is must go through a switching module output dc 5 V working voltage.
Emission coil and receive coil distance for 1 ~ 20 mm, if small current work can be appropriately increase receiving coil turns to increase transmission distance
Test data, for reference:
Emission coil: copper wire diameter φ 0.6 mm, coil diameter 40 mm, around 20 turns. Receiving coil is same.
Emission coil grafted in 12V power supply: standby working current300 ma, load is 4.2V 800mAH polymer lithium battery

If receiving distance increase it's need to add the coil turns.
In ractical application, it can change the turns of coil to adjust the power.
1, mobile phones, MP3 and so on wireless charging
Modern people have more and more without mobile phone and so on electronic small product, but frequent charging is trouble and often drawn connection-peg and easy to damage, use our wireless charging modules, as long as the phone on charging a flat plate can automatic charging, still can take at any time or answer the call, is really convenient.
2, in the aquarium lighting and water circulation system of the power supply
A fully transparent fish bowl forth beautiful colorful light will make the viewer is very curious, its electricity is how to? The secret is to our wireless power supply module, this kind of application is also very market prospects.
3, concealed products provide power supply
Some special occasions will need a functional hidden installation into other products in the shell, usually by batteries, which has? How to charging problem, if eduction charging joint will be easy to notice, use our wireless charging module is the best solution.
4, hydrophilic products supply
Such as electric toothbrush, electric razor this kind of product often and water contact, it is often hard to mouth to charge for waterproof processing, using it we wireless charging, electric parts completely sealed, thoroughly dust waterproof, and improve the product specification increase added value.
5, design waterproof phone or intercom
The market of mobile phone, intercom typically use the plug contact charge, so it is difficult to really waterproof, using the wireless power supply can be full seal design completely waterproof.
6, wireless radio frequency card application development
The traditional wireless radio frequency card technologies to produce energy is very small, therefore can only achieve short identification function, and our module can provide 500 ma current, greatly expand the application function, for example, can join the voice prompt, sound and light show or wireless transmitting, and other functions, many occasions can also use no battery design, not only reduce the cost also can improve the service life of the product.
7, medical field
Some medical equipment must work in the human body, such as timing agent pump, capsule endoscope, etc., using the wireless power supply scheme can greatly prolong the working time of the equipment, highly practical value.
Because the product unceasingly to improve, some module circuit board a few place may and physical map slightly difference, but guarantee function is the same.
