nnck Posted May 26, 2015 Share Posted May 26, 2015 Has anyone found an external battery or power supply that can be used with the Klipsch KMC3? There were some reviews on Amazon or some other sites that mentioned that this could be done using a 32000mAh external power pack connected to the DC input. There was no mention of what specifically was used. I’d like to verify that this is true and find out specifically what has been used and how well it works. Whether I buy the KMC3 is probably going to be dependent on this information. Thanks Quote Link to comment Share on other sites More sharing options...
WMcD Posted May 26, 2015 Share Posted May 26, 2015 The manual downloaded from klipsch.com has instructions about using "the" external power supply. So it seems to come with the unit as purchased. This looks like a typical laptop power supply. Are you asking about some sort of external battery? You mention a 32000 mAh power pack. That translates to 32 amp hours. A pretty good sized "Sealed Lead Acid" battery (SLA) can do that. It will be large, and heavy. I wonder if the information you received is correct.

nnck Posted May 27, 2015 Author Share Posted May 27, 2015 Thanks William. I am not referring to the regular external power supply (the one you mention looks like a laptop power supply). I am indeed referring to some sort of power pack or battery supply pack. As I mentioned, someone in the Amazon review section mentioned using one of these with one if these boom boxes. The person who posted did not go into specifics about what they were using (32000mah power supply was all that was said). And they didn't address someone's specific question asking exactly what this was, so I was wondering myself if this was real or not. So I don't know if this can be done. I was imagining some sort of power pack that you plug into the AC to charge up, and then unplug and bring with you to plug into your other devices, giving them power for some time before you need to charge the power pack back up again.

WMcD Posted May 27, 2015 Share Posted May 27, 2015 Okay, I understand now. Here is something I found. It will deliver 12 volts and higher if needed for another application. This is a plus in my book. What I don't know is whether the plugs will work with the Klipsch unit. But it seems it comes with quite a few. http://www.all-battery.com/tenergypower16multi-voltageforlaptop-51097.aspx Generally I find that nothing is cheap in these external power / battery supplies with rechargeable batteries. In my research on other projects I've seen that D alkaline batteries are very respectable as far as energy to weight. Better than rechargeable types.

Thaddeus Smith Posted May 28, 2015 Share Posted May 28, 2015 It runs off D batteries.. So just buy rechargeable batteries. Quote Link to comment Share on other sites More sharing options...
WMcD Posted May 28, 2015 Share Posted May 28, 2015 I looked at that. With 1.2 volts per cell, it might not work in the Klipsch unit.. But D cells are cheap in bulk. It seems to me that you could buy ten sets of eight for less than the external units. WMcD Quote Link to comment Share on other sites More sharing options...

I was seeing things like this on Amazon. But of course, I'm not going to try it unless I knew for sure it would work. http://www.amazon.com/XTPower%C2%AE-MP-32000-Power-Bank-Notebooks/dp/B00VIB8KAW/ref=sr_1_1?ie=UTF8&qid=1432779888&sr=8-1&keywords=32000mah+external+power+pack Quote Link to comment Share on other sites More sharing options...
WMcD Posted May 28, 2015 Share Posted May 28, 2015 The only potential issue I can see is whether one of the variety of tips will fit the Klipsch. You probably will not know that for certain unless you buy it and try. WMcD Quote Link to comment Share on other sites More sharing options...
