In this project, we'll take a look at building a portable Qi charger. This universal standard works with many devices and can still charge non Qi enabled devices via the USB port on the side.
In a previous project we built a 3d printed stand to hold our charging transmitter but in this project we'll make it portable with a PowerBoost 1000C and a beefy 6600mAh battery!

Maximum output is around 5W which is good for most smart phones, basically 1000mA charge at 5V on the other side of the wireless connection. It has a charging distance of 2-8mm!
We've built smaller portable wireless Qi chargers for wearables like the Apple Watch and have found it useful enough to leave behind one less cable while traveling.
You can also just connect to a 5v power supply - through a micro USB port. If you want to 'share' the microUSB power connection, you can also connect directly to the USB-A port. |
