I have a partial solution. I’ve had a BlackWeb party 18AA014 speaker for a few years. Loved it. Then it stopped taking a charge June 2021. When the speaker’s power switch was flipped on, the speaker would start up and look normal for 5-7 seconds then immediately shut off. I was about to trash it but I noticed that when I would flip the speaker on (for the aforementioned 5-7 secs), the speaker would try to connect to my phone via Bluetooth. So I tried this:
1) Opened the Bluetooth settings on my Iphone
2) hit the Blackweb Bluetooth link on my phone to start the pairing process just before I flipped the speaker power button. The speaker then came on, linked to my phone and stayed on?!!
As a reminder, the speaker was plugged into a wall socket using the power cord the the whole time. The speaker stayed on overnight (again while plugged in). [br]
The next morning I unplugged the speaker. The speaker would now turn off and on using only the battery….hmmmm. But don’t get to excited just yet. The battery meter was full. The speaker ran off the full battery for about 15-20 minutes but then died. At this point, at least I can now use the speaker while plugged into a wall socket but the speaker won’t take a charge. Good luck.
