Qtek9090 do not charge

Hey I have old Qtek9090 and after long time of unusing I managaed to charge it. I plug my USB cable, and charging LED blinking in an orange color. When switched battery lock it turns red, bit lights still, not blinks. Battery is new, maybe it was used for a month only and it was working. With LG GT540 charger it don't wake up too. Screen is whole time off, nothing else work, just LED is on.
Any solutions here?

Hi i charge my BA with USB Cable (not charger), led is red and not blinking Just wait

Cześć, ładuję BA za pomocą kabla USB (nie ładowarki), dioda jest czerwona i nie miga. Po prostu poczekaj

I used usb cable too, without ac adapter. Phone was connected for almost whole day and it still remains as is.
Też samym kablem ładowałem, ale anwet jak cały dzień tel jest podłączony mam tak samo i to się nie zmienia :/

Same was happening to me :/

Try connect usb without battery, so connect battery after that.
The battery needs to have some charge on it so the cradle can be used to charge it alone before you put on mobile.
If no cradle is available try with a replacement battery. I bought one and it came with 7% charge on it and it was enough to do the trick
Best of luck!

Voltage question....110V to 220V

I plan to buy ouya on Amazon and then ship it to China(yes,I live in China) Here's my question. Ouya has 110 voltage but Chinese voltage is 220V. Do I need to use adapter? Maybe this is stupid question,but I am not sure if ouya would be blow up when I plug it into slot:banghead:

It runs on 12V dc so you'll probably have to get an adaptor that will take 220V ac down to that. I don't think the one it comes with will do that.

I looked at my adapter and the stock adapter I recieved a AC to DC adapter with
Input: 100-240v` 50/60Hz 0.6A
Output: 12V 1.5A
Looks like my stock power supply supports 220V sources. Don't know if they would vary on power supply models. 12 volt dc power supplies are a dime a dozen, not a serious problem.

I'm in Germany an we also have 220v. Working like a charm.

I looked up the Chinese wall outlet. This may not support the plugs from the standard North American outlet. The voltages will work but the plugs themselves may not fit. So unless you request the region specific adapter, you will not be able to plug it into the wall. Sorry
The good news is 12 volts is very common, all you need to do is find something with the same plug for the back of the Ouya and amperage rating equal to or greater (preferably equal to) 1.5 amps. If you think you have one that may work (fits but you are unsure about the rating) send me a pm.

Really? Ouya will work under 220v without any adapter?

Sure. The only thing you might have to use is any form of world travel adapter to be able to plug it into your country's socket. I'll add a photo of the lable. It clearly says input 100 - 240 V.
Gesendet von meinem HTC One X+ mit Tapatalk-4

I personally use one of these http://ecx.images-amazon.com/images/I/51XjaHgSHtL.jpg
But any generic psu with the right values and plug will work.
I figured out my wd live TV hub and my external hdd also have the same plug, voltage and polarization. Just one of them is able to deliver a bit more amps but that doesn't matter because it's always a question of how much amps the device will demand and not how much the psu will push through the device (you remember ohms law?)
Funny thing to mention:
You can even run your ouya from the power of your PCs USB port. Therefor you have to make an adapter from USB to DC input. But caution: on high load this might pull more amps than your USB port might bee able to deliver.
This is possible because ouya is internally using a step down module regulating the voltage down to 5volts. So anything between 5-12 Volts should be good so long as polarization is right. But if you don't know what you are doing just stick to original DC adapter

Thanks. I have already bought one and I have been waiting for my Ouya.

[Q] Fast charger

Can anyone with a Find7a let me know what the spec of the vooc charger is? They don't seem to sell them separately on the Oppostyle website and I usually like a second charger for work.
Thanks

Have it at home and am in the office (i get your point xD)
But i read in another thread, that it has extra pins for full power charging. Without that extra pins you dont get full speed charging.

4.5 amps instead of the usual 2 you see on the market.

That's annoying. I was hoping it was just a higher amperage. They sell N1 chargers on http://europe.oppostyle.com but not Find 7a ones.

The 4.5 amps are reached by having multiple power lines on hidden extra pins.
So yeah, vooc is proprietary, no way around it.
Gesendet von meinem One mit Tapatalk

But if we are already talking about the charger i have two questions as well.
My overall understand of charging and power tells me, if i plug the vooc charger in another phone it will load with the amperage the other phone accepts. So there should be no damaging - right? I dont feel ready to test it without asking you before that
The other way around, using my old charger with me Find 7 should work fine as well, shouldnt it? Of course with even longer loading time depending on the power of the charger. This night I tried charging my Find with an old charger of my Galaxy Nexus (I think something around 1A which worked well with my Nexus 4). I expected it to load waaay slower. But actually it didnt load at all. I am not absolutely sure at wich perantage i started, but after about 8 hours i got no remarkable change, maybe a few percent. Is there a minimum Amperage needed?
Thanks for your thoughts

You are correct.
The extra voltage is pumped out via additional pins that a normal USB connector doesn't have.
The other way around you can of course charge the find7 using conventional USB chargers, just slower of course.
As for minimum amps... All my other chargers give me 2 amps and that works.
Also charging on my computer via a USB port works great... Those output I think only 500ma...

If you plugged the VOOC supply into another phone it shouldn't cause electrical damage - but the extra pins on the charger COULD get damaged.
It's more than just the extra pins - the VOOC power supply uses two pins (possibly D+ and D-) to communicate with the phone.
You'll get normal (but fairly rapid, I need to check but I think it's at least 1.5A) charging using a standard MicroUSB charger.
Edit: Can't find the exact settings, but the charger chipset supports settings of 3A, 2A, 1.5A, 1.2A, and some lower settings. Stock is probably 1.5A or 1.2A

That's some good info there so thanks guys.
It still begs the question, how do you get hold of spare or replacement vooc chargers?

quick charger

Is there some sort of special quick charger needed? None of my qc2 or qc3 chargers charge this thing at any sort of reasonable speed

Only the Huawei Quick chargers work. I have a Blitzwolf charger that isn't specifically quick charging, but it charges it fast enough. Also my Chromebook Pixel charger charges the P9 very fast too. USB C is amazing - I love having one charger for both the phone and laptop!!

Hi do you know how long the phone do a full charge? It is faster to the Huawei Fast Charging?

The Huawei 9V2A charger is much faster. See the discussions and timings etc here ... http://forum.xda-developers.com/p9/help/charger-huawei-p9-t3373037

I purchased this:
https://www.amazon.com/gp/product/B00QEX83LA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It charged from 52% to 81% in 30 minutes (61.1%/hr), and another instance it charged from 27% to 90% in 70 minutes. (52.4%/hr). This is without touching the phone (screen off). Also I am not using the cable that the phone came with, not sure if this matters.

If I want order from ebay or aliexpress. Which should i get thats legit? EU plug.

Does P9 use Quick Charge 3.0 or 2.0 ?
Confused right now

Neither, it uses Huawei's own Fast Charging protocol. Don't get a Qualcomm QC2.0 or 3.0 charger, they wont fast charge the p9

Waiting for your feedback to purchase or not.
But the one i got from original package seems to charge pretty fast already

I agree, also first 30-40% seems to be charge pretty quick... Mmm placebo effect? Who knows... At least are not burning out like others [emoji10] [emoji10] [emoji10] SGN7

I just order quick charge from china (aliexpress.com). It took 15 days to reach me in saigon-viet nam.
After testing, an interesting is that, when you use adapter quick charge (9v-2a), there are two thunder symbol appear on battery i/o one when you use original charge.
I am not sure the timing charge will com shoter. I will do some test and let you now.
But one thig you need to know, your p9 gonna be lag when use the quick charge. I am not sure this fault come from my quick charge adapter or because by itself function

It does not lag here, but you need to have in mind that real quick charge kicks in when screen is off. I see wattage difference in my wall tester the charger uses when I use the phone and while it is idling.

Alternative Warp Charger

Hello,
i wanted to ask if there is any alternative to the Warp Charger PSU. Can i just take any 30W from Amazon or do i need special Requirements?

The output has to be 5V, 6A for warp charge. The normal chargers have quick charge 3 or usb c pd but those standards use higher voltage and less current, so they won't warp charge the phone.

sad -so there is nothing yet - thanks for the answer

I don't think so. Was searching myself. The phone should still charge pretty fast with the normal pd chargers though.
Gesendet von meinem GM1913 mit Tapatalk

An Oppo SuperVOOC charger could - in theory - charge the OP7Pro with 25W (it works by delivering 5V/5A to two smaller batteries simultaneuosly, resulting in a total output of 50W. As our OP7 has only one battery, the maximum should be 25W). But we won't know for sure until somebody tries

Yes I use a pd at night and it's still fast but the warp is 60% faster so it's significant. I mean while I made a pot of coffee and tidied up the kitchen I went from 9% to 60q. 20 or so minutes
