Hand tools and fabrication machines
Hi everybody! Im sick and tired of all these small and ugly powerbanks that doesn´t have capacity enough to even charge your cellphone once. So this is how you make your own that you can customize with diffrent lids with a capacity up to 16000 mAh. There is an assambley-video step-by-step on the youtubechannel.
You will need a bottom, a lid and a powerbutton, you can find everything at thingiverse:http://www.thingiverse.com/thing:2261807
I printed it at 20% honeycomb-infill PLA.
First insert your powerbutton.
Solder your batteryholder to the USB-PCB, red to bta+ and black to bta-. MAKE SURE TO WIRE IT IN PARALELL! like in the picture, else you will burn the PCB due to high voltage!
Assamble the PCB and batteryholder,insert batteries, try if it work before you glue everything in place!
Tight the screws and enjoy. The outputs and inputs schematics is:[ 1amp ] [ Input ] [ 2.1 amp]
You may also use it as a LED-flashlight two fast clicks on the powerbutton and the LED lights up.
