AAA To AA Qi Battery Holders

Hello World,

 

I have a short post about what COMPACT has made! It was very impressive that he made the AA and AAA holders with the 3D printer. I wanted to share with you a cheap alternative for those of us that do not have access to a 3D printer.

 

I bought a set of these BlueCell simulated battery holders a while back and now I finally have a chance to use them! Now you can get these pretty much everywhere online, just look up AAA to AA Converters. They are used to convert a AAA to a AA size of battery. You can get pretty much any type of Conversion you would like.

 

Starting from the left is a AAA Battery, AA Battery, AAA inside AA Holder, Empty AA Holder, AAA inside AA Holder, Tips of the AA holder.

They are very inexpensive and now whether a 3D model or these holders, everyone will be able to transform anything battery powered to a Qi Powered Device with ease.

 

 

Problem:

I have made a simple way to add a buck boost chip inside one of the batteries. This uses all of the voltages combined and boosts the voltage to a battery voltage. There are different versions of this device, since the Qi Receiver outputs 5.0V, we need to be able to access the different voltages for different devices. Example 1:

     A TV Remote usually has 2 AA or AAA batteries = 1.5V x 2 = 3V

     A TI-89 or other simular calculator has 4 AAA batteries = 1.5V x 4 = 6V

 

Therefore, a battery holder can have a built in step up/step down or buck boost to solve these voltages. A small Qi receiver will be built in between the two AAA batteries and a coil is easily mounted on the door of the TI-89.

 

I will post a solution to this problem later.

 

Thank you,

 

Chad
