Wireless phone charging cheap for your car

Concept how to retrofit your #car with wireless charging option cheap – for less than $10. This #DIY project is going to work in all cars, even if there was no wireless charging option. Also all phones are supported, even if wireless charging is not supported by your phone.
You will need: emitter for your car, receiver for your phone, case to hide the receiver, USB charger or 12V-to-5V step down converter and a micro-USB cable.
Basically all you need to do is connect the transmitter to your car and hide it under a flat surface that you’ll place your phone on. As soon as the device is in the right place it will start to charge the battery.
In this video I tested it in BMW X1 (E84) and iPhone 6. I also tested the transmitter with iPhone 8 and iPhone X.
Depending on how much free space you have in your car I would recommend to use transmitters with many coils to make sure that the charging area is wide and it’s easier to put the phone in the most efficient place to charge the battery.
