Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆
Apr 18, 2016 at 3:12 PM Post #16,261 of 42,856
I'm not concerned about Mojo in summer and here is why:

I don't leave any electonric device out in direct sunlight.  In pocket, it will be warm, as it is when I use it at the same time it is charging.  Also, I have some experience with warm batteries, including 18650 lithium flashlight batteries and my son's pitching machine for baseball, which is also the smart lithium battery.  With it running, it has to be in the sun, and it gets warm, but as other owners have pointed out, no one really knows how to store it and the last few years, owners (me included) have found that plugging it in, or forgetting to, or it falling out during winter...the battery remains terrific year after year.  

I've always had success with lithium batteries, including the hand held drill, and portable vacuum.  

When I listened to Chord's description of the battery and the fact that they do not know how long it will last, "25 years?", I felt then, and now, after testing it, unconcerned and confident.  

I think we have a tendency to over think and fret because of rechargeable batteries have not historically been great products.  Much of this changed with "eneloop" batteries that were taking 500 or 1000 recharges, and on to the lithium batteries that can shine a 4000 lumen flashlight.  

The technology has improved and playing mine straight through came close to 10 hours though less with on and off.  I think that for those of us who may have real need for lots of portability, the recommendation for the portable power bank for the Mojo and phone is a good idea.  I also consider that USB charging is available in so many places today; not just airports, that I cannot anticipate ever turning on Mojo and finding it not up to the task.  

I am not mindful of the time it is plugged in, versus deliberately running it down.  

My sense is that this is not something we need to fret about.  

If you want something to fret about Mojo, consider this:  Mojo's perfection with sound makes my guitar playing sound awful.  How's that for a downside?
well thought out and in your case most likely you dont use EQ, play at low volume and sit near a usb charger all is just darn good. In my situation I walk, I take trains, I jump on buses to get to one school then another school then another. This sort of traveling usually takes a good 3 to 3.5 hours of walking and standing then coaching which is standing. So when on my way home the Mojo suddenly turns off thats an issue hence trying to really see how long the Mojo last on one full charge. I would not use the word "fretting" when this running out of charge happened a couple of times. Connecting the Mojo to a dap with a coax cable drains the battery less than say going with an optical cable ? Using Mojo with a phone drains the batter faster than the Mojo optical route ? The only reason I ask is because something actually happened. Now a pitching machine under the sun and an amplifier in a pocket are two different things. Like a Tennis Ball machine I had I didnt worry about it being under the sun nor did its battery ever ran out so I never tested how long will it run plus I didnt think of the battery getting too hot. It did have air flowing through it. Mojo in my pants pocket has no breeze no air and it gets hot very hot so your pitching machine and Mojo are two completely different.

  Finally got Win 10 today on my Lumia 930 phone, and the bugger doesn't work.
Tried two different cables and no joy
 
I can now finally finish my 6 month long review

I have both the 930 & 950XL. Much to my disappointment I too discovered the Mojo is incompatible with Windows Phone. There is no support for USB Audio Class 2 with W10M and I'm uncertain whether this could be fixed via  a software/firmware update or not. I sent an email to Chord and the response acknowledged the fact that Windows Phone is unsupported.
 
If you or any other WP user is in the Windows Insider program for W10M OS builds then I urge you to visit the Feedback Hub and upvote or add to the requests for USB Audio Class 2 support.

Hey anyone listen to Ed Sheeran via mojo? Im streaming over Tidal in HIFI listening to his first album using my cayin c5 and android sabre dac. I wish I had listened to it using mojo as it sounds fantastic on this set up so I imagine he would sound better again on the mojo

With the pitching machine, flashlight, etc, I mean the temperature of the lithium battery as well as the charge/use cycle is not something to fret over. I don't think the Mojo in the pocket is going to get so warm as to be an issue, but this opinion is based upon the mentioned uses with lithium batteries.  I do understand the products, pitching machine, and mojo are different.  The machine, however, is black and the battery is right out in the sun and it does get hot, but I have not noticed a difference in time used from overcast or from sunny days.  
 
As to your commute, that would cause me to fret because it is so long and complicated and...I would easily get hooked on passing the lengthy commute with music and it would drive me crazy to have it cut out.  
 
I wonder if a portable power bank would be the best help with the commute and Mojo?
 
Also, perhaps Chord can weigh in on if they think the battery's power will be impacted by pocket temperature on warm days.

I think the entire Mojo battery issue needs to be put into perspective.
 
think of Mojo as you would an all electric car say like a Tesla S
 
the car is an absolute beast in acceleration yet has less than a 300 mile range.
 
want some heat.... range decreases
want to drive at night.... range decreases
want to play the stereo on a long drive... range decreases
 
Mojo is the same way.
 
want the volume cranked... lose battery life
hard to drive transducers... lose battery life
want to pocket it and generate extra heat... lose battery life
 
you want an electric device and want it to last... make it a hybrid
alternative power source means longer life means happier Mojo owner
 
Moral of story...
 
Invest in at least 12000 mAh powerbank... nowadays they are small enough and cheap enough to make it worth carrying one
 
this rant is in no means meant to insult anyone or denigrate their feelings, it is meant to draw a comparison between a battery powered hot rod and a battery DAC/ Amp that mimics each other in power consumption metrics
 
rant over let the Flaming Begin!

  I ordered a usb cable from larvicables and honestly i like it very much and looks amazing as well and good quality


Do you intend on using it exclusively, or get the module?
 
I paid $32 for the right angle fake Fiio cable.  I have had to re-start the iPhone to get it to 'recognize' it...
 
twice now.  
 
As to the battery, as long as I have a safe place to have a good cry, process and have my feelings affirmed, I should be okay.

I'm sorry to hear that, although I'm going to, respectfully, stick to what I said, earlier.

LOL - reminds me of something someone else said, quite recently...

If Microsoft haven't seen fit to provide native support for this in the desktop version of Windows 10 it seems a bit of a long-shot that they'd invest the effort to add it to something with a comparatively tiny user-base (even if a lot of the core is the same).  No reason not to ask for it ... but I wouldn't be holding my breath.

I, too, held this opinion, until recently, but I'm now more confident about the 3rd-party cables (Chord still doesn't proactively encourage them, though, as you rightly point out).
 
Broadly-speaking, there seem to be lots of people using them successfully.
 
If the 3rd-party cables were using an MFI emulation chip, then it'd probably be easier for Apple to scupper them, but, since they are (AFAIK) using genuine Apple MFI chips, culled from genuine Apple CCKs, they're probably reasonably safe to take a punt on, as long as one doesn't need to go into debt to afford one

My confidence in the third-party cables has grown also ... particularly as the one I bought (Lavricables) has survived multiple iOS upgrades now (on 9.3.1) without issue - and one of those upgrades made some significant changes to CCK support for iOS, especially on iPhone.

jmills8 I'd say get a power bank bro. In case you haven't thought this out, maybe charge the Mojo at school? :wink:

In all seriousness, with the length and torment of your commute, powerbank would help keep your sanity.
Haha thanks for the suggestion to steal schools juice. Joking, think all I need to do is leave the house fully charged. My plan was not to charge it every day.

Hi everyone, my name is Max.
I'm new to the forums and would just like to say that I am super impressed with the mojo. No audio product has moved me like the mojo. 
 
During the first three days of using the mojo my eyes began to shed tears and I would shake my head in disbelief while listening to tracks I previously heard before.
 
My father is an audiophile himself and he owns a high end stereo that consists of VTL MB 450 Series III mono blocks, VTL 6.5 series II Preamp, an Auralic Vega (now updated to a Lampizator lite 7) and B & W 802D speakers so I'm no stranger to high end audio. I bought myself an HD 700 and Schiit Valhalla 2 and hooked it up to the Vega and used that as my previous reference. He was extremely impressed with mojo as well and when hooked up to the stereo as a line out, the mojo was competing with the Vega. The mojo had a more forward and detailed sound signiture while the Auralic had a wider and still detailed sound signiture. One of the things I picked up was how well the mojo reproduced the timbre of the guitar. 
 
After over two weeks of testing and getting intimate with mojo I am now a fan of Rob Watts's FPGA WTA Algorithim. The amplifier in the mojo is super transparent and in my eyes significantly bests the Valhalla in terms of transparency. Using mojo as a lineout to valhalla only changed up the sound but isn't needed as mojo seems to be powerful enough. A buddy of mine owns a pair of HE 400i's and just for kicks we plugged in both our headphones into the mojo. To my surprised the only difference we could hear was a slight decrease in volume on both headphones (around 1-2%). It drove both headphones well but for some reason I felt it might have lost a bit of kick on the 700's.
 
I showed mojo off to my family and friends some of their jaws dropped when they heard their favorite songs being played. All of them agreed that its well worth it and its an excellent purchase.
