I've become obsessed with the idea of adding a USB port to my bag, in order to have a stable way to connect to my auxiliary battery/power bank when needed. The bank would stay inside the bag, safely tucked in its own internal pocket, and the phone would be out of the bag either in my hands or in stashed its own external pocket.
Just need to find the part with the proper connections! See the second and third photos at this link for an example -- looks like two plates on either side of the bag held together with four screws: https://www.amazon.com/TPRC-Luggage-Durable-Constructed-Millions/dp/B0762R442M/ref=sr_1_11?gclid=CjwKCAjwq5-WBhB7EiwAl-HEkrblxXNEMzxnfZAga-8rN4Cl5mFlsBO9khTS_zyjKHe9u6VtJv0NjBoCFDkQAvD_BwE&hvadid=323322926105&hvdev=c&hvlocphy=9008123&hvnetw=g&hvqmt=b&hvrand=14540748905164423900&hvtargid=kwd-361529555265&hydadcr=4490_9620643&keywords=spinner%2Bunderseat%2Bwith%2Busb%2Bport&qid=1657316888&sr=8-11&th=1
Does anyone know where I could purchase this part? I've googled fruitlessly, but maybe I'm not using the right search terms.
