The Bose Community Forum was launched at a time when robust online support was not available for Bose customers. Over the past several years we have added new online service channels that provide a more interactive and complete digital experience. Additionally, we have enhanced the My Bose Account capabilities to deliver a more personalized and self-service experience. As a result, Bose has made the decision to close Community Forum for Consumer electronics products on September 30th. The Bose Pro portion of the Community will still operate as usual.


Please visit our support homepage to experience one of our many other digital service channels or simply use your Community log-in credentials to sign in to your My Bose Account to view your orders and view support options.


Thank you to all who have contributed and benefited from interacting in our Community. We look forward to continuing to serve you online.

L1 Compact Battery Pack - Email Sent To Bose

Dear Bose,

Here’s a little background on me with regards to Bose audio products.

My name is Nicholas Peper. I'm a professional singer who also plays keyboards and key-bass. I’ve been getting paid to perform since 1965 and I'm now busier than ever. Even at my advanced age of 68 years.

I was an early adopter of the L1 Classic. In fact, I bought 2 PAS + 2 B1 Subs at Guitar Center on Sunset Blvd in Hollywood, CA the night that Bose did the first product launch and demo. I sold one of those systems to my drummer and kept the other for myself. I've loved that system and used it successfully for many years. Alas, it has gotten a little heavy for me to lift and tote so, it’s on eBay as I write this.

On December 17, 2017 I purchased the L1 Compact from Sweetwater and have been very happy with it as well. 

On April 7th, 2018 I bought the new S1 Pro including the battery pack from Sweetwater and have been extremely satisfied with this unique and versatile speaker which I use primarily as a vocal monitor even on loud Rock gigs. Thank you so much for sending me the Carry Bag/Backpack at no charge.

Last week I received a COOLIS 200Wh-54000mAh Portable Purely Sine Wave Lithium Battery Power Inverter Generator Power Station, with Silent 110V AC/12V DC/5V USB Output that I’d purchased from Amazon for $149.99 (Please see the link below).

https://www.amazon.com/gp/prod...00?ie=UTF8&psc=1

PianoManChuck had mentioned this product in one of his YouTube videos. Mostly he reviews various brands of professional portable keyboards and has been a proponent of using battery power when possible while performing at venues with limited access to power outside or when it’s not practical to run long ungainly extension cords. I’ve trusted his recommendations before with good results, so I thought that I would take a chance on this Coolis device. 

My intent was to power a Yamaha mx88 88 note keyboard, Yamaha MG06X mixer and the SingularSound BeatBuddy drum machine for a three to four hour long engagement. Totally off the grid, so to speak. 

On the spur of the moment, I decided to try connecting the L1 Compact instead of relying exclusively on the S1 Pro with battery for amplification. I was astounded to find the Coolis capable of powering the L1 Compact and since it has a Pure Sine Wave output, I felt confident that I wouldn’t be causing any damage.

After a total of six and one half hours powering everything except the S1 Pro, the Coolis showed three bars out of a maximum of 5 on the LED display. In other words, about 60% of battery power was still available!

There was no increase in the noise floor coming out of the L1 Compact . The cooling fan on the Coolis never kicked in nor were there any Battery Management alerts.

Even though there are many potential battery solutions out there for L1 Compact users, I lucked out finding one that does the job safely, quietly and for a reasonable price. Others might not be so lucky. 

I suggest that if Bose created an Official L1 Compact External Battery Pack Option, many of your loyal customers would be thrilled to add portable power capability to their beloved Bose L1 Compact system(s).

Thank You Bose for your wonderful audio products and for listening to your customers.

That’s awesome! I was super excited when i figured out how to power my pedal board with a battery -  done several 5 hour gigs with that and my S1 Pro on battery! I’m putting and L1 Compact and Coolis on my birthday list! (won’t get it, but I can dream, right??)

Re: L1 Compact Battery Pack - Email Sent To Bose

Alas, they won't ship the Coolis to where I live...

I've used a regular inverter and 150 AH deep cycle battery before.

Now I use 2 S1s, a battery powered Behringer mixer (3 rechargeable 9v batteries), battery powered phantom power, and a rechargeable battery for my stomp pedals...very cool...

I also found my Bose L1 Mod 2 with 2 B1 subs only pulls about 40 watts so it could be run for hours on the deep cycle battery and inverter...

Thanks Nick Peper for the info the Coolis.  This is the sort of useful information I've come to expect from the members on this forum.  I've learned a ton of stuff about my Bose gear and how to get the most out of them through this forum -- and info like Nick's about the Coolis keep adding to this insightful database.

PPT Powerpack 400 from Powertech UK  www.portablepowertech.com

Absolutely amazing. I have been searching for a long time for something like this. I operate a Bose Compact amplifier system for busking. The calculations for units power draw were on the Bose forum and Dave at Powertech was exceptionally helpful and guided me through the options. Price dictated that I could not take the lithium option at £500 so I opted for the PPT400. I used it for the first time last Saturday, and after four hours of constant operation....I ran out of singing power first !! In fact the PPT400 hadn't even gone to amber. It has all the power I need, for all the time I need. For the job I wanted it to do... 10 out of 10. I will be writing about this on the Bose forum, as it answers a lot of questions about how to take a brilliant 240v amp out onto the streets and perform with a reliable source of portable power.. Brilliant, thanks Powertech. www.garyocean.net

Re: L1 Compact Battery Pack - Email Sent To Bose

Thanks Nick, I just purchased and received the Coolis. I just charged it.  Can’t wait to try it out. Its a lot smaller than I envisioned. Smaller than a lunchbox. I play as a duo.  Dont know if it can power everything we both have, but even if we both buy one for our own gear, its a good deal.  I’ll report back on what I find.  Thanks again.

Anyone have any experience with the battery powered pedalboards from either Boxking or Outlaw Effects (called Nomad)? They look to be the same board with a different label.

I am very happy that my Post on the Coolis Power Station helped you to discover and decide to purchase the Coolis. I hope that it works as well for you as it has for me.  I look forward to hearing how it performs in your given application. Best of luck.
