I've edited my previous reply to you (which I've reflected, in the quoted text you see below this sentence) , so please refer to that (I was editing it, and updating posts #2 and #3, whilst you were posting your reply, so, sorry, I was unaware)
 
 

 

  So I want to charge and play at the same time without using battery like a desktop dac/amp. I do not want to use the battery and let the mojo draw current only from the power supply. Does it matter if I plug the power source before turning it on or plugging it in after turning it on?

 
 
You cannot completely avoid using Mojos battery. As John Franks has remarked, there is a slight net drain on the battery, even whilst plugged-in.
 
 
Please see the discussion in the section of post #3, entitled  'Battery & Charging'  /  'What happens when you charge & listen at the same time?'
 
 
Also, Rob has been good enough to provide me with additional detail on this matter, today (which I am also adding to the above section in post #3, but will share here):

Thanks for clarifying, Rob.

Thanks, so basically turn the mojo on and then plug in = trickle charge mode = no timer.

 
 
I think that would depend on what charge state Mojo is in to begin with. If Mojo was already fully-charged, then yes, provided I am understanding your meaning correctly.

Lithium batteries are rather contentious, in terms of how people say they should be used, but not all lithium batteries use the same chemistry (other than the lithium component), so not all lithium batteries necessarily behave in the same way, or need to be used in the same way.
 
Personally, I would have no concerns about using Mojo plugged-in, whilst in a fully-charged state, on a regular basis.
 

  Just to clarify. Charging is automatic. If you are playing and charging at the same time, with a fully charged battery, the charger will supply enough current to balance the consumption used by Mojo, so no net current into the battery. If its fully charged and the unit is off, the charger will go off. The charger will re charge automatically when the battery voltage falls to 8.2v (off at 8.4v) so keeping the charger connected will ensure a full charge.

Can anyone tell me what is the frequency response/range of the Mojo? Thanks.

Please look near the top of post #3, in the section entitled 'Device Performance Measurements', and you will find links for independent measurements.

Thanks. I turned my mojo off while in full charge state and the white light disappeared, but I am guessing mojo is still drawing a little bit of current to keep it fully charged. I will turn it on tomorrow and see if it will start charging. If not, I'll just have to replug it everytime I guess.

I am confused by one aspect of the whole Mojo battery charging thing, and I have read all the posts.
 
What confuses me is that there is only one set of wires connecting the battery to the Mojo circuit board. (Or only one set that I have seen.) I think that must mean something no-one has mentioned that when the Mojo is plugged in and playing at the same time. At some points in time the Mojo must be taking power to play music straight from the charger.
 
Meaning when the battery level drops a little and the charger is engaged. The charger is supplying more power than the battery is supplying to the Mojo. To make sure the Mojo keeps playing and tops up the battery.
 
However I keep reading that the Mojo only takes power from the battery. How can that be right? I can't imagine how the charger is supplying power to the battery going up the battery cable. While at the same time power is coming down the charger cable to run the Mojo.
 
I guess I must be seeing this all wrong. I have tried to imagine it with diodes in place but still can't figure it out.
 
Maybe I just don't understand the battery.

Did you see what I posted, earlier (on this same page), from Rob?:

Yes of course @Mython. However it doesn't describe what state the Mojo is in does it? Playing, off, on but not playing.
 
He is talking about when there is no net charge on the battery. I am talking about when the battery level has dropped and when it needs a bit of charge. (While charging and playing, from a full battery.)
 
To be honest though I have probably over looked a simple principle of electronics and should know better.

I can see what you mean.       Rather than speculate, I will let Rob answer your query, when he has time, but that probably won't be today, as he has his hands full, at the moment.

Thank you, Yes as awesome it feels and I might say Stacking doesnt matter, practicality and portability of the same on a daily basis might be a big pain. I wont deny what you said. Just the world of DAP is equally confusing. , dont think I can buy new device every other year, thus want to be future proof.

There are lots of great daps out now. My current favorite is the Cowon P1. You can find then for $699 now and it's my favorite player. Has plenty of power, excellent sound, eq, dsp, etc. I think the sound is comparable with the Mojo.

Now you have us all intrigued as to what he may have in his hands today? 

 
The other speculation however is now over - as I confidently predict that power is consumed when the unit is on whether it is playing or not but it will automatically detects when the battery needs to be charged again, including when it is switched off. (but having said it confidentially, I may be wrong

)

 

[Mython]

  ... you have us all intrigued as to what he may have in his hands today? 

 
Nothing exciting.    Exceedingly mundane, actually.   Think no more of it.
 
 
Anyway, I'm glad you've drawn a conclusion
