The one I have has mini usb for power, so you can use a phone charger or usb battery pack. I guess you could also use a car usb charger for 12v battery feed, but you might need to try a couple of different types because some chargers interfere with the audio. Took ages for delivery so perhaps find a different seller! But this model works perfectly, I've had a couple different types and some are a bit temperamental, Bluetooth drops, noise etc.

Thats a good idea actually using a aux bluetooth adapter. It will stop me accidently pulling the aux out my phone then. And also save some space in my 'amp/cables box' by getting rid of my long aux lead.
I assume your bluetooth aux adapter is battery powered?

Thinking about it booster app probably won't drain the battery much using an aux lead because the input impedance to an amp is much higher than wired headphones etc. but definitely chews the battery using the phone speaker. For home I use a Bluetooth aux adapter, tenner off eBay and sounds perfect.

Phones usually have a software cap on aux volume to stop you from damaging your hearing using headphones too loud. The EQ/volume boost apps just override the level cap in the phone software. Does the trick but it does drain the phone battery quicker too. Edited by Sonic the hedge - 23 May 2020 at 2:05pm |

The only thing that really affects battery life is how loud you have it playing.
All of the other adjustments you are talking about are just ways of getting to that final output.

Cool okay thanks very much again for all your help!
I will be getting it all out soon for a first test in the garden. Its only been tested in my garage so far but it really exceeded my expectations indoors. The true test is outdoors i think though. Thought id best wait for a friday to test it in the garden as neighbours probably wouldnt be too pleased midweek haha ๐
Also last question, i have a 'Equaliser FX Pro' app on my phone which i have to use when i plug my phone in via aux as for some reason the volume goes really low when on aux. Anyway, it has a volume booster which i turn on and then also i adjust all the EQ through there, which seems to work really well. I assume this also wont have any significant effect on the power draw as now it seems like its also kind of similar to the amps gain knob. Or am i very wrong?

No not exactly... as he said itโs just a (passive) voltage divider, not a real gain and even if it was, at that point were talking low voltages with relative high impedances or a very low power difference in whatever the position of the โGainโ would be. Even if it was a true gain (which it is not), it would still be very, very, very marginal in terms of power consumption or battery drain.

Oh right i see, i thought the gain would effect the power drain.
Right im starting to get it now then. Thanks again! So for the battery to last longer then, i would be best off using a low voltage input like a phone. Instead of say decks or something more powerful.

The battery drain will be proportional to the effective power put out by the amp, not the position of the gain/sensitivity/level pot. You can have the gain on the amp all the way down and have a source putting out say 5V or so, than the amp will drain the battery substantially, because it it close to maximum power. With the gain on the amp all the way up, but a source barely touching 0,1V output, youโre not even at half power. Itโs all relative ๐. |
