Fast shipping!
I thought it would take at least two weeks to get this item given the current state of affairs with the Coronavirus spreading. To my great delight, it showed up just a few days later! Would absolutely order from them again.

DOES NOT fit appropriately for Onyx Studio speaker as advertised
This is a poorly built piece of Made In China garbage, covered in typos and illegible lettering on the label. It looks and feels flimsy, cheap, unreliable, and probably dangerous (that UL label appears dubious to me at best). I was willing to overlook that and just keep it unplugged when not in use, but come to find out it doesn't even work as advertised. It does not charge my Onyx Studio. It will power the speaker while it's on, but will not charge its battery, and any bumps or nudges and the cord just falls right out of the charge port. If you have the Onyx Studio 1, DO NOT BUY THIS. It is not the right size, and even if it were it appears to be poorly made crud. I feel like I've been had. And now I need to get to the copy store to pay to print off a shipping label to return this faulty garbage. Probably not worth the inconvenience for $16.99, but honestly, I don't want this company getting to keep my 17 clams.

Doesn't Fit Proprly
The plug doesn't fit properly in the speaker. It is too loose and keeps falling out. I'm going to return this item for a better quality charger.
