Solar Battery Bank Case (To Transform Your Backpack Into a Solar Charger!)

thingiverse

The case includes a cutout for the power LEDs (it shows what percent battery your battery bank has), a cutout for the panels to fold out, and cutouts around the corners to make it easier to take out the power bank. You will need: 1x Solar charger (I have confirmed that the following chargers work: https://www.amazon.com/IXNINE-Portable-Wireless-Waterproof-Nintendo/dp/B07VTNMJV4/ref=sxts_sxwds-bia-wc-p13n2_0?cv_ct_cx=solar+charger&dchild=1&keywords=solar+charger&pd_rd_i=B07VTNMJV4&pd_rd_r=36629263-d5b9-4cf7-8a6d-09a09ff565bd&pd_rd_w=ulcHq&pd_rd_wg=wwBmX&pf_rd_p=13bf9bc7-d68d-44c3-9d2e-647020f56802&pf_rd_r=T02774VA8VPCCSD9V5JF&psc=1&qid=1595092958&sr=1-2-791c2399-d602-4248-afbb-8a79de2d236f https://www.amazon.com/Tranmix-Cargador-resistente-tel%C3%A9fonos-inteligentes/dp/B07T48YYW2/ref=sxts_sxwds-bia-wc-p13n1_0?cv_ct_cx=solar+charger&dchild=1&keywords=solar+charger&pd_rd_i=B07T48YYW2&pd_rd_r=36629263-d5b9-4cf7-8a6d-09a09ff565bd&pd_rd_w=ulcHq&pd_rd_wg=wwBmX&pf_rd_p=13bf9bc7-d68d-44c3-9d2e-647020f56802&pf_rd_r=T02774VA8VPCCSD9V5JF&psc=1&qid=1595092958&sr=1-1-791c2399-d602-4248-afbb-8a79de2d236f) 2x M5 screws of any length between 10mm and 30mm. 2x M5 washers of any diameter between 20mm and 30mm 1x strip of velcro (hook and loop sides) I assembled this onto my backpack by making holes in the nylon with a soldering iron, then screwing the screw with the washer through the backpack into the case. Afterwards, I put the battery bank into the case, folded out the panels, and attached the bottom panel with velcro, which I sewed in on the backpack side but found the glue to be more than enough to stick to the panel side. It has held up for a few months now, despite biking, skating, travelling, and running. I also really enjoy how the panels fold with my backpack when I access the front compartment. It provides a very good angle for the charger - it is constantly charging outdoors.
