Customer service agreed that it doesn't make sense, yet here we are 🤷♂️
Makes bundle deals significantly less appealing to me. I have always used bundle deals fairly extensively, but I suspect coins + coupons would generally yield better discounts now.
Hi all, I'm a beginner so this might be a bit simple/obvious.
I decided to try replacing some batteries (2x aaa) with a USB cord. I got a mini-360 buck converter, and successfully adjusted it to step down from 5v to 3v, but when I connect it to the battery terminal, the output is pulled to 0v and the input is pulled to 3.3v.
I tried wiring the 5v USB supply directly to the battery terminals and that also gets pulled to 0v.
I removed the converter and replaced batteries, still works perfectly.
Help please?
