Phone charger question
I purchased a 3.1A double USB charger that had an SAE connector with the hopes of using it to charge my phone on rides. Installed nice and clean, connected to the pigtail on the battery that had a 7.5A fuse inline.
Quick checks before heading out and even a 15 minute ride and everything worked well. Left the phone charging with the bike off with no trouble, started back up for the next leg of the trip and noticed it wasn't charging. Pulled the seat and the fuse was blown. No biggie, replaced it with a 10A, due to availability, after I made it home.
Connected the pigtails and immediately popped the fuse and saw smoke...turns out the USB side had smoked and changed color.
Contacted the retailer and they sent a replacement right away.
Connected the new one to the pigtail, new 10A fuse, bike off, starting, running...no issues. Plugged the charge cable in and tried all again, no issues. Plugged in my Galaxy S7 and everything worked great. Let it run and sit with the bike off for a few minutes each with no trouble. I unplugged the pigtail and reconnected it (with the bike off, phone plugged in) and phone no longer charged, even attempted with different charging cables.
Anyone had any similar trouble or have any ideas on why it would work until I reconnected the pigtail with phone connected?
TLDR version: USB charger connected to battery tender pigtail smoking and not working
