Ok so this is a quick review of a desktop usb charger that I've been using for the past week.
The device is the Choetech Multi Port Desktop Charger.
So I figure I would get to point first then going further into details
THE BOTTOM LINE:
This device is not for everyone, but if it is for you, you'll love it with a personal rating of 4.5/5.0
Pros
The device is light weight and easy to travel with.
The device have a total of 6 charging ports 2 of which support Qualcomm Quick Charge 2.0 .
The device have a real nice matte finish.
and my favorite, the device ports are all real nice and snug, so there is no chance of accidental unplugging.
Cons
Unfortunately, the only major con I found with it was the price.
**As an after thought** It would have been nice if the auto detect tech work on all 6 ports not just standard ports. (If my understanding if correct)
Performance?
The device have a total of 6 ports with an output of 5V/9V/12V with the 12V being reserved for only the 2 quick charge port. The 4 standard ports on the device boast Choetech "Auto Detect" Technology meaning that it can automatically detect the max voltage for your device and output accordingly.
But if you're buying this device for it's QC technology you're probably more interested in the how well it perform compared to other quick chargers?
For my testing I used my Nexus 6 with CleanRom, and the stock usb cable that came with the phone, I also compared the Choetech device against the stock adapter that came with my Nexus 6.
To ensure a fair and relatively accurate results I followed the following procedures for both chargers 3 times to ensure no unusual data.
I drained my phone completely until it auto shut off, charged the device for exactly 30 seconds to ensure enough power to turn the device on.
I then place my phone in airplane mode and cleared all recently used apps.
I used the Playstore app Battery Monitor Widget in order to take a min by min reading of the charging process.
Finally I charged the device for exactly 10 mins (I went with 10 mins because the purpose of Qualcomm QC technology is to get as much juice in the least amount of time)
Results?
Unfortunately, the stock charge narrowly beat out the Choetech by an average of 1% for a ten minute charge(Choetecht charged 13% in 10 mins the stock 14% all three times the test was conducted), however Choetech beat the stock charger with an average of 2-3 degree Celsius less battery temp during that 10 min charge times (I think this is a bit more important considering the narrow gap in percentage charge considering the fact that battery temp have a direct effect on the lifespan of batteries.) Also if you care both the Choetech and stock charger took just under 2hrs 15min for a complete charge.
Usefulness?
This is why this device is not for everyone. Choetech market the device as a replacement phone charger, which if you intend to use it solely for that purpose and you only have 1 phone in your possession, there is no justification for purchasing this device.
However, if you're like me and you have several a bunch of peripherals like that doesn't require a data connection then this is perfect for you. Another example where I've personally used it in the past week was when I had guest over instead of everyone trying to find an outlet to plug there phones up I just plug this device in a central location that everyone could easily access... My wife have the S6 Edge and now we both can use QC tech at the same time without her annoying unplugging my phone , and finally I had a FTX with my Army Reserve Unit this week as well, and if you every had to sleep in a tent with 20 other people then you know how scarce an outlet is to charge your phone... but with this 6 people were able to charge up at any giving time.
Conclusion
So there you have my complete review of the Choetech Desktop Charger. Decided for yourself if its something for or not. Also keep in mind that your miles may vary as no 2 device is the same even if they were constructed the same.
If you like a video review to accompany this writing review just let me know
Bought two of these. It's just okay
Once the Nexus 6 reaches ~70% the Quick Charge port refuses to charge my Nexus 6 anymore. If I move it to one of the other 4 ports it will keep charging.

Sorry but can't say I experience the same issue. I was able to fully charge my Nexus 6 with the qc ports. My wife is also able to fully charge her S6E as well, but like i said "your miles may vary"

lol better?
Love this.. I have 2. 1 on my desk and one in my suit case for travel. It saves space and plugs and charged all my. Devices quickly. Was excited to try it again given the 1st time I purchased one, the device short circuited and never worked again. Since I liked the idea of what the product represented, I bought it again.
Fyi....there is a deal currently...http://www.androidpolice.com/2015/0...rt-usb-charger-for-17-after-a-7-off-coupon/#1
Meh.
Hi guys, I've a problem, it's the fifth battery charge I do, and I notice that battery had charged almost 41% in a minute, it seems really strange, I suppose it is a sort of software problem calibration or somewhat else. I've done some screenshot to let you understand.. do someone has the same issue ? it's really strange, I've used an Aukey charger , the standard one with quickcharge 2.0 that I used to use on the xioami mi4c wich I've substitute with the plusx one.
tell me what you guys think about it, could it be a battery problem?
OK guys problem solved it's a software problem evidently
BTW is there someone who has this problem either ?
Steady with the consecutive posts! Yeah I think someone on the Oneplus subreddit had this to, just need to recalibrate the battery: http://android.stackexchange.com/questions/29598/how-do-i-recalibrate-the-battery-of-my-phone
Hello,
I have updated to B330. Now the phone seems to take more time to charge than in the lollipop with fast charging option enabled. Is there anyway to reenable the fast charging option? Should I move for a 18w charger?
I also have doubt regarding the temperature of my phone.
Can anyone please share the temperature readings of their phone during gaming with cpu-z or any method.
Please help
Somebody please helpp
I think you cant disable the fast Charging option , or I cant find the option on MM.
Its not the fastcharging like the one from Qualcomm , you dont need a new charger.
It actually is somewhat similar to Qualcomm QC, and to take full advantage of it, Huawei Quick Charger is required.
More details and link to quick charger here
Any updates on this? I swear they removed the update. And they've gone back instead of forwards with mm. It's freaking ridiculous
All we need a basic feature to be enabled / developed by developers to kernel i.e Charge rate control.
Other features can be focused after this.
The most wanted feature we want from kernel is fast charge support.
Option to enable 2.1 or 2. 4 Amp charge input.
All other features are secondary.
To fully charge redmi 3s takes 3hrs. with input of 1.4 Amp.
Please work specially over this feature.
Whats your opinion?
Great idea..
Sent from my Redmi 3S using XDA-Developers Legacy app
i am fine with the charge speed , i think i can leave my phone for atleast 3hrs once in 2 days . I'd rather prefer slow charging to keep my battery running for longer . My phone takes exactly 2:25 hrs to charge fully
I also make sure to turn off data and wifi and close running apps while charging , dont know if this is making a difference
Hey,
A few days ago I got an update to MIUI10 Beta for my RN3 (snapdragon). After uploading the update, my phone started to charge with a maximum current of 0.4A (screen turned on, 0.6A when turned off). I decided to unlock the phone and flash LineageOS 14.1, unfortunately I still have the same problem.
Searching for topics related to this problem I found a "solution": https://forum.xda-developers.com/redmi-note-3/how-to/fix-slow-charging-t3662571
I tried - it does not work.
I tried also wipe cache/dalvik - it does not work too.
I tested on 3 chargers:
1. Apple 2.1A Out
2. Apple 1.5A Out
3. no-name 1.0A Out
-----
I used 6 cables for the test - on each of them the same.
Summary:
Before the upgrade to MIUI 10 - loading about 3h 0-100%,
After upgrade to MIUI 10 - charging about 8h 0-100%
After changing to LineageOS - charging about 8h 0-100%
Additional info:
I have this RN3 for 3 years. Maybe it's battery problem? After 3 years battery capacity has dropped from 4k to 3.2k-3.3k.
I would ask for help in solving this problem.

Okay, I flashed miui and... nothing. RN3 is still charging 0.41A.
Second anomaly - on Xiaomi Powerbank 10k, RN3 is charging 0.72A
Third anomaly - 11h charging from 18% to 100%.
Fourth anomaly - RN3 is charging only to 75%. I have plug off and plug on charging to continue charging more than 75%.
-------
Any suggestions? Maybe should I change the battery? Maybe this module with usb port?

Take ear bud and apply some spirit alcohol on itand clean ur charging port of ur phone. May be sometimes dirt or carbon or rust affects the current. Spirit alcohol or isopropanol is volatile and helps in cleaning the charging port.
If u dont have spirit alcohol then buy a small bottle from pharmacy.
I have the same problem in miui 9 then I installed lineage os but issue remains . then I tried random kernal problem solved

Okay, I changed ROM to ViperOS and it was still 0.41A, so I decided to flash NitrogenOS. A little bit better. Now it's charging on 0.80A on 13% battery.
Maybe some more suggestions?
Thank you so much for replies. I really appreciate your help!
@edit
Now charging from 13%-100% take "only" 5 hours. It's bad result but it could be worse (11h on 0.4A).
@edit2
Also fifth anomaly - RN3 is randomly turning off after show a 0% battery notification. (On LineageOS 14.1).
Maybe this is problem with overheating battery. When battery is too hot system limits charging current. Did you tried measure real charging currend using eg. multimeter?

Hello there,
I have this small buddy:
https://ae01.alicdn.com/kf/HTB10vcSQVXXXXbRXXXXq6xXFXXXk.jpg
and all values which I wrote here were measured by this.
I will try thermal libs on NitrogenOS.
UPDATE
I tried thermal libs - nothing changed.
I have a notification on lock screen: "Slow charging (5hr to 100%) 715mA - 3.9V - 34*C"
Even I am facing this exact same issue after MIUI 10 update and it persists even when I changed the ROM to DotOs. The extra bit of information I can add is, the only reason for me to flash custom ROM was to get the charging done faster and immediately after flashing the ROM it did show "Charging Rapidly at 2022mA" in the lockscreen(a custom ROM feature) but only for 3 times and after that it keeps showing 0.4mA as the charge current. In my opinion we need to flash an older firmware of MIUI as MIUI might have purposefully done this in its latest update to make charging safe for old batteries (mine too is 3 years old!) and temperatures where climbing up to 45°C when it was fast charging. Any help would be highly appreciated with a thank you.

Why don't you just flash a custom kernel, instead of ROMS
I tried plenty of ROMS - POSP (PIE), Bootleggers (PIE), CM14 (Nougat), LineageOS (Nougat), NitrogenOS (Nougat).
I tried few kernels - Radon (for PIE and Nougat), Shadow (Nougat), AGNi (Nougat) - For all kernels I checked few options - new thermal lib, old thermal lib, QC 2400mA, default options and other variations.
I corrupted my persist.img (all of my sensors were dead) due to flash too many of roms/kernels/stuff - had to flash new through fastboot
On all of roms/kernels/stuff I had 0.41A - Only on Bottleggers I had 0.6A and NitrogenOS 0.8A max.

Can you tell me, which kernel would improve my charging?
update (18.03.19 3:23PM):
I changed stock kernel (ROM: LineageOS<Nougat> - 0.41A) to Badjingan pie. Actually I did it completely by accident. I thought that this is a nougat kernel. Aaaaand... it increase charging to 0.8A. Checked on USB 3.0 in laptop, Lenovo QC charger and no-name charger 2A.
Another update (18.03.19 5:27PM):
I changed the Badjingan kernel to Radon 6.3 for Nougat. Again 0.41A and nothing changed if I choosed new or old thermal but I found an option in Radom Kernel Control which is "Quick charge by USB" and when enabled, the current is changing from 0.41A to 0.80A and that's it.
Update (26.03.2019 12:20PM)
I flashed stock Miui 10.2 Global (Android 6.0.1) and charging issue still remains.
Also tried to flash thermal libs - still nothing.
I will order new battery and usb charging module.
Hello there again.
After this tries above I ordered a USB charging module in my RN3. So few minutes ago I mount it up to phone and check if charging is better. Aaand... Nothing Still 0.41A. Checked on POSP 9.0 (stock kernel). Tomorrow I'll try to change to other kernel (maybe Viper N).
Few days before, I changed ROM to Miui 10.2 Global. The charging current was aprrox 0.06A-0.2A.
The same problem
I have the same problem. As you have described, it has also happened to me after upgrading to the latest version. I have Already tried with different chargers and cables but nothing. I don't think it's a coincidence, I've already been through all the Roms that are here but I have not solved anything and the issue begins to be tired.
Thanks for reply. We will figure something out
Okay so there is an update:
I've changed (again) to MIUI 10 Beta ROM -> 0.41A
I've installed AGNI Kernel with old thermal libraries option (during installation) and... 0.66A from laptop USB 3.0 on 50% battery. The same current on MI Powerbank 20k.
The next and the last thing before throwing RN3 through window is replace the battery.
Stay tuned
I used to charge it while watching videos or playing, but today that is no longer possible. Sometimes, for example, being at 20% battery power and connecting it while I do those activities, it stays at 20% all the time or even low instead of charging.
I don't know in your case or if you've already tried it, but I've seen that the problem is only charging the phone when it's on. If I charge it when it is turned off, the charging time is normal. About 2 hours.
Clean flashed Havoc OS 9.0 Rom and Nano gapps + Thunder Kernal
Everything seems to be working fine.
Only 1 big issue is that The phone is super slow charging now,
Using a blitzwolf 2.4A/QC3.0 charger and the cable can charge at 1A or more on my Oneplus One but on the Redmi Note 3 SE (kate) seems to charge only around 0.2A
I use to be able to Charge at 2A under stock MIUI ROM
but since flashing this rom barley gets past 0.2A
Anyone know why?

Hahha.....lol..
Get ready to go service center. Never use quick charge 2 or 3 on rn3. It will burn ur charging board.
Always use stock charger 5v 2A.
it worked fine for 3yrs, only when I changed the Rom did i encounter the slow charge issue
