In my big box of cables I have, among other things, a double-ended USB-A cable. I understand that this is absolutely not standards compliant, and I have absolutely no idea of where I got it from. I have never used it. But it is a thing that exists.
Getting rid of almost 10 different proprietary charging cables for pre-smart phones and some old laptops felt great though :P
- MrDOS 6d agoI had one of those to charge a bicycle headlight. I gave it away with the bicycle, but in the span of time I had it, one visiting guest borrowed it to recharge a portable generic USB battery pack. So there you go, two product categories known to use that sort of cable!
- sanj 6d agoThis came with a double-ended USB-A for charging: https://www.rei.com/product/248291/biolite-luci-original-clear-20-inflatable-solar-lantern https://www.rei.com/product/248291/biolite-luci-original-cle...
- jauntywundrkind 6d agoMine came from usb<->sata adapters.
- 1-more 6d agomine had 2 male USB ends on one side and 1 on the other. It was to power a laptop hard disk drive from USB if one port couldn't provide enough power. Feels illegal. I bought it off eBay with a money order in like 2003.
- toast0 6d ago> double-ended USB-A cable. Decades ago, I purchased a usb external hard drive case with a usb-a for the connection to the computer. Returned that pretty quick because eww.
- kps 6d agoThere are also cables that look exactly like a double-ended USB-A cable but aren't. https://ftdichip.com/products/usb-nmc-2-5m/ https://ftdichip.com/products/usb-nmc-2-5m/
- tikhonj 6d agoNeat, I had never heard of those.
- moritzwarhier 6d agoYou and the other responders are probably familiar with it, but you made me look up this decent StackExchange answer again, coming from a search for "the forbidden usb cable" :) https://electronics.stackexchange.com/a/444287 https://electronics.stackexchange.com/a/444287
- majorchord 6d agomine came from a USB charger spycam
- creaturemachine 6d agoI installed some HP slide-out rackmount keyboard/monitor units that used these as the host connection. This was back in the days when PS/2 was still around so they usually weren't used.
- VCFundedGenYer 6d agoDouble-ended USB A cables were popular in the 2000s/early 2010s for powering external hard drives or USB DVD drives.
- jameshart 6d agoPut a USB C to A adapter on each end and you’ve got yourself a perfectly serviceable USBC cable.
- qurren 6d agoI have a few of those too. My laser cutter needs one. I've seen lots of "expensive equipment" use USB A-to-A cables, for some odd reason.
- tom_ 6d agoI've got a 7 port USB 3.0 hub that connects with a double ended USB-A cable.
