When it comes to small portable BT speakers I think it needs to be said that from time to time almost any BT speaker, phone or other BT receiving or broadcasting device will at times act up. Sometimes when they just fail to work you have to delete the entire setup in the device being used and then set it up all over again. I've had to do this both in my car and with my BT mini speaker. I drive a newer Subaru at work and for some reason when I setup the BT connection on the car radio system it suddenly stopped working ( connecting ) for some unknown reason. After I deleted my phone from the car system and setup the whole thing again it now works fine, go figure. The same thing happens with my desk top computer from time to time. Just the other day I was trying to use my mini BT speaker in my house and was having all kinds of problems. It would connect for a second and then the BT speaker would just announce that it was turning off...what the... I'm still not sure what the problem was. Right now I'm not sure if the speaker is charging because when I plug in the USB it just turns red for a moment and then the LED light goes out. Not the first time I've had a BT speaker with electrical / charging issues.. I think sometimes the internal wiring inside connected to the USB port just starts to have problems. Anyway, since the speaker wouldn't connect and stay connected with my desk top I turned the BT off on my Desk top and then tried to use the speaker with my phone. With the phone it worked fine, no problems. It seems the main issue with my little Jam Alloy speaker is with the usb port. I have to set the plug at a particular angle or it doesn't charge. That really sucks but at least it's working for now. All of my charging cords are fine. The speaker does the same thing no matter what usb cords I use ( and I have several ).

I finally ordered a new BT speaker for the road bike. I chose one being sold on Amazon but I'll not post a link to it till I get it and see how it works. The Amazon reviews on the model I ordered were better than most so I'm hoping that the reviews were not fluff. Hoping to get it by the end of next week but depends if they run out of stock. They had four left when I placed the order.
