Wireless Power Supply Coil Module Wireless Charger Module Description: Wireless power supply technology(wireless charging) allows the receiver only across the air， paper or plastic housing can achieve the transmission of electrical energy， indeed greatly facilitate the application. Specification: Input voltage: DC 5V - 12V Input current: 100mA - 500mA Output voltage: DC 5V Output current: 500mA - 600mA Output power: 2.5W - 4W Center resonant frequency: 125KHz Feature: Emission coil and receive coil distance for 1mm ~ 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 !#!amp!*!phi;0.6 mm， coil diameter 40 mm， around 20 turns Receiving coil is same Emission coil grafted in 12V power supply: standby working current 300mA， load is 4.2V 800mAH polymer lithium battery Distance Output voltage Charging for 4.2V lipo battery current 1mm 5V 600mA 2mm 5V 450mA 3mm 5V 360mA 4mm 5V 310mA 5mm 5V 240mA 6mm 5V 210mA 7mm 5V 162mA 8mm 5V 150mA 9mm 5V 132mA 10mm 5V 120mA 11mm 5V 110mA 12mm 5V 70mA 13mm 5V 54mA 14mm 5V 41mA 15mm 5V 28mA 16mm 5V 19mA 17mm 5V 17mA 18mm 5V 10mA If receiving distance increase it's need to add the coil turns. In practical application， it can change the turns of coil to adjust the power. Application: 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. 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. 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 ea
