For those of us who liked Jawbone products, you will be disappointed to learn that the company disbanded and no longer supports their old products. Fortunately, there seems to be a decent non-OEM market for replacement parts for their products on Amazon. I have purchased a replacement battery and now a new A/C adapter, which together have completely restored the function of my speaker.This adapter indeed charges the battery, but it's slightly too long, exposing a small amount of metal in the barrel when plugged into the speaker, which I just find irksome. Functionally it doesn't seem to make a difference, but still, how hard can it be to make an appropriately sized plug, particularly when you advertise that this adapter is made specifically for this speaker?Hopefully the charger lasts for awhile, though some reviews indicate otherwise. I will certainly update my review if the charger fails prematurely, but for now I'm satisfied.

Worked for a while then broke without cause after several months. I couldn't get a read with a voltmeter. I bought a different charger (from a different manufacturer) to replace this one and the new one works just fine

Stumbled across an Big Jambox at a Goodwill for a $1.99. Looked to be in good shape but was missing it’s charger and did not power on. Rolled the dice and ordered this replacement power adapter. The Jambox worked flawlessly with this adapter, and it quickly charges a replacement battery I installed as well.

It worked a few times, then slowly stopped, now it doesn't work at all. Could be the Jambox, I don't have another charger for it to test it.

We bought this to replace our jambox cord and it works great.

Bought for my big jawbone as a backup. Charger does not fit all the way in. It’s about 1 cm short of fitting so it does not charge

We used it for our speaker and works perfectly! It’s good value for money, versatile and sheerness.

It fits a little awkwardly but it works. The fit to the Jawbone base is different than the original charger but it seems to work fine.
