Tube boom box, nice sound, easy quick wireless connect.
A bit bigger than I thought it would be, but this thing puts out some nice sound! Bluetooth connects super easy and fast. Battery life is exceptionally long. I love the dual battery port too (m12/m18). Added bonus it has a usb that can charge your phone and an audio input with 3.5mm jack. Also comes with a wall power supply if you don’t want to use the battery.

Describe Yourself:
Milwaukee m18/m12 jobsite speaker
I have only one complaint with the poor Wi-Fi it's so weak even with my phone being on top of the speaker it plays weakly and the volume goes up and down to the point where you can't even hear it, I have to use the pin to pin to keep the sound even. It sucks. Other than that I think it's great and I'm happy with the speaker.

I need this power cord??
eduardo z on Nov 7, 2017
BEST ANSWER: What do u need?
Does it have am/fm radio?
Trey C on May 15, 2018
BEST ANSWER: No. Strictly a Bluetooth speaker. If you wanted to listen to the radio (live sports, etc.) you would need to stream it via your Bluetooth-enabled source device (like a smartphone) or connect a Bluetooth transmitter to a radio and pair it with the Milwaukee speaker. The alternative Milwaukee model # 2792-20 M18 Jobsite Radio & Charger has an built-n Bluetooth receiver.
Does it pair with 2792-20 ?
Wendell D on May 14, 2018
BEST ANSWER: No, both the radio and speaker only receive the bluetooth/wireless signal. You could only use 1 application at a time.
Does it charge the battery when a.c. adaptor is plugged in?
Alex B on Sep 26, 2018
BEST ANSWER: Model 2891-20 will not charge the battery when the adaptor is plugged in.
Is it water proof ?

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
