  5V/2A is the best solution than 5V/1A.
And yes it does shorten the charging time.

Really bro? the 5V 2A is better then 5V 1A? why so? whats the difference on the (A) between time, charge or something?
I have 2 charges here over 5V 1A, and i was considering to buy the iphone 6 charger that's 5V 1A

I charge my Mojo with my Nexus(2015) charger which is 1.5A.
The thing is there is a term called as "Conversion Factor", so what's mentioned on the charger, that's the output @ 100% efficiency, but we know nothing in this world is 100% efficient.
Also with time the efficiency of the charger & cable decrease, so it's better to use 5V/2A charger :)

I charge my Mojo and AK100mk2 with the GS4 charger which is a fast charger.

Hey bro... do you GS4 using with Mojo? i have some questions...
if  NOTE 4 is better then GS4 quality with Mojo. I dont wanna buy new NOTE4 if i already have the GS4,
so.. i will just upgrade the SD CARD to 128GB.
 
What can you tell me about the GS4 with Mojo and have you test anothers Samsung with Mojo?

Is 3A is the maximum the Mojo can take?


I don't know for sure as I haven't used a 3A charger, but like I said, the Mojo should only take what it needs.

  Does anybody know the battery capacity on the Mojo? sometimes i use a 5000mah external battery, which the Mojo completely drains, and it barely goes to green level(i get about 4--5 hours of use after this charge). Also, i read that Chord recommends charging from a 1A/5V source. Is there any problem if i charge with a 2A/5V iPad charger? Honestly i didn't check to see if it shortens the charging time. 
The thing is i travel a lot, and i prefer to have with me a single 2A charger, which i can use for my iPhone, iPad, and hopefully for the Mojo.

Mojo's battery is actually about 14Wh - Watt hours - is a better measure of battery capacity, as Mojo has two cells with a max total voltage of 8.4v. Your 5000mAh external battery is maybe only 18.5 Wh (assuming it is a single cell), and when you figure in inefficiencies in power delivery, you will need more than 18.5 Wh from a portable battery to fully recharge Mojo. 10000mAh single cell should be fine.
 
As other posters have said, 1A is min, 2A is fine but Mojo will not charge any faster. I have controlled the charge time for thermal reasons.

That's a lot of power for the size of battery. Well done!!

Fairly new Mojo user here, maybe a week or so.  At first I had been using it purely with my iP6+ or with the Carbon.  I liked it, but still waiting for that Mojo moment that I've been reading about.  Today, hooked up my old school Pioneer DVD-V7400 transport to Mojo via coaxial connection.  Now we're cooking.  Definitely not going into any technical details about the sound as it is just first impressions, but here the source is making a difference in my perception of the music.  Just sounds more live and dynamics are excellent.  Next up will be my computer as a source.  In the meantime, I'll be re-discovering my CDs.  Like most of you, I've owned cheaper and more expensive DACs.  The Mojo just sounds excellent.  Doesn't really need to be compared to anything else.  This is a good time for DAC buyers.  I feel the iFi DSD Micro and Mojo are really giving us amazing bangs for the buck.  Micro was another favorite of mine, but it's been a while since I owned one so I'm not going to draw comparisons, but myself would be happy with either one, each having its own disadvantages/advantages.

Right now I have paired the Mojo with AK100mk2 and sometimes with iPhone 6 Plus and not tried yet with GS4 since I do not have OTG micro cable. However, I believe the SQ of GS4 is good enough to pair with Mojo.

Well I'm about to order this Anker Charger for my Mojo

Hopefully it won't break the Mojo

Does n't matter whether you use Note5/Note1/GS1/GS4.
You will feel difference only when you will play some DSD file, because to play DSD you need more power(Ram, Processing speed).
 
For other FLAC/ALAC files, IMHO there will be zero difference no matter which source you use.

Thanks so much!
