Stock Charger or 2.1 Amp Charger

My question is would using a 2.1 amp wall charger over the stock charger pose any danger of damaging my Flo?
Sent from my Nexus 7 using xda app-developers app

My stock charger is still unwrapped.
I'm using a 2A charger for all my tabs (Nook HD+, Nook Touch, old & new N7s).

The charger spec just lists the max output. The tablet is the one that decides how much current to pull. So it is safe to use the 2 amp charger.

How fast will it charge with an 2,1 amp charger ?

At this point, I don't think it has been determined. Install a battery monitor to see if it draws more current with a 2a supply over the stock 1.3a.

I am living in Germany so I don't have a Nexus 7 yet. But the charger of my mobile phone is broken and I would buy the 2amp charger, if it charges faster because I can use it with my Nexus 7, too.

There is something to be aware of when buying a 2a supply. The original Nexus 7 required the data pins (2 and 3) of the charger to be shorted in order to draw full current (don't know if the new one behaves similarly).
The majority of usb chargers out there are designed with Apple products in mind, which shunt a resistive load across these pins to tell the device how much current is available. The result of using the original Nexus 7 with these chargers is that the device only draws about an amp.
My experience has been that HTC chargers have the correct pins shorted, while Monoprice's do not. Your on your own with any other brands. You'd need to measure those pins with an Ohm meter to be sure.

Best wired charger for nexus 5

Hi. Can you guys please tell me which charger you are saying. And which is the best charger for nexus 5 which takes less time to charge up the battery. I recently lost my stock charger and the other chargers I have are taking much longer time to charge the phone they are like 500mAh chargers so its taking long time. Can you guys pleas suggest me the charger.

Check another post in this sub forum. It has links to the BlackBerry playbook chargers, which are awesome and cheap.

The HP 2.1 amp charger is the best charger

I second this - bought a bunch of these chargers to use everywhere.

I'd go with the blackberry folding blade chargers.
There's a review thread someone did. Lots of people here have it. http://forum.xda-developers.com/google-nexus-5/accessories/hands-best-fastest-cheapest-nexus-5-t2729066
It's also so much cheaper than the HP touchpad charger. On amazon you can get anywhere from 4 - 8 chargers for the price of 1 HP.

Just use a USB cable with a MicroUSB port at one end. You always have a computer next to you.

OP was looking for something that can charge faster than 500mA which USB charging is limited to. At that speed it can take 4+ hours to charge the phone vs 2.5 hours with stock, and 2 hours with a 2.1A unit.

My GF got an LG G2 at roughly the same time I got my phone.
I've tried charging my phone with a wide variety of chargers, including the ipad 4 charger, as well as other 2.4A heavy duty chargers from other companies. I dont know why, but NOTHING is as fast as that stock G2 charger. It beats the "heavy duty" voltage stuff by a noticeable margin.
It does a proper quick charge on her G2, and while I've read that the nexus 5 doesnt really support that quick charge, it DEFINITELY does something.
It looks like this: http://www.lg.com/us/images/cell-phone-accessories/wcp-300/gallery/medium05.jpg

I am not sure if you will get the folding blade charger in India. You can buy the CP AD2 charger. One of my friend bought it and the Nexus 5 is charging at around 1300-1400 mAh. You will get it in Amazon for 550 rupees.

Old Nexus 6 Charger?

This is probably a dumb question, but if I buy some USB-C -> USB cables, can I use my old Nexus 6 charging bricks and still get fast charge on my Pixel? I have a couple of them from my Nexus 6, and I'd hate for them to be useless now.

Don't take my word for gospel but the OEM Nexus 6 charging block has the same output voltage as the pixels block.
Sent from my Pixel XL using XDA-Developers mobile app

I used the USB cable that came with the XL with my N6 charger last night. Seems to work just fine.

You absolutely can. Just make sure you have a Benson approved cable.
Also, it won't charge as fast as the OEM charger.
The N6 Charger Specs:
Nexus 6 battery is 3220mAh Turbo charger rates:
[email protected]=14.4W (Turbo 2)
[email protected]=14.4W (Turbo 1)
[email protected] =9W (Standard output)
You will only get standard output since the Type-C standard is 5v only. So you will charge at approximately 1.6A rather than the approximate 3A from the Pixel Charger

Did you guys ( gals too . . . ) see the www.fixit.com tear down ?

wtf ! there were the qualcom qc 3.0 chips soldered onto the main board . . .

Below is a quote from a Google engineer from another forum.
"Will it be safe to use my nexus 6p USB-C charger with the pixel/XL?
I would advise against it. Please use the charger that comes in the Pixel box with it.?* The Nexus 6P charger will technically work with the cord it comes with, but if you use a USB-IF certified USB3.1 cord, the Nexus 6P charger behaves badly.
You do not want to risk a $800 phone on a $10 charger. If you use the OEM 18W Pixel charger, warranty will cover any problems you encounter.
Also, will it be safe to use any qualcomm Quickcharge charger?
Is the Qualcomm QuickCharge charger USB Type-A (square plug) or Type-C (round plug)?
Type-A (square plug) QC chargers: it depend on the manufacturer. Some make good chargers, others make bad. It depends on the maker.
Type-C (round plug) QC chargers: these are bad and go against the spec. I do not recommend using any Type-C Qualcomm QuickCharge chargers.
also, according to the processor spec, it does support quickcharge 3.0
No. The Pixel does not support QC at all. It uses USB-PD (PowerDelivery) at [email protected] and [email protected] levels. You need a USB-PD power supply with those levels or greater.
will there be any harm or advantage if i use a quick-charge 3.0 certified charger?
You need to speak to QualComm. I have personally tested "QualComm Certified" chargers that are bad. I have data to prove this. However there are many "good" QC3.0 chargers as well.
There will be no harm (if the charger is good). There is no advantage (if the charger is good). A QC Type-A charger will work like any other USB-A port and charge at 1.5A maximum. (It remains to be seen if the Pixel will recognize Apple 2.4A charging.)."

Awesome, thanks for the reply! So from what I am understanding, the cable is more important than the charging brick? I charge my phone every night, and I want to avoid fast charging in that scenario since I've heard that Fast Charges create more wear and tear on the battery than a standard charge. That being the case I'd like to use an old standard charging brick (like a samsung one) and then use a certified USB - USB-C cable to charge the phone.

My Nexus 6 block and pixel USB cable does not say charging quickly. It just says charging.

Sometimes those estimations vary quite a bit. Reinserting the plug resets this, and can sometimes change the estimation by a few hours.

USB-C chargers with QC3 work fine with the Pixel2XL?

Hi,
I have 2 chargers that I used with my older phone, both are QC3 compatible, USB-C port and 1 of them can deliver 5/9/12 volts.
no matter if I use 1 of them or the charger that came with the pixel2xl I see (in Ampere app) it always charging at around 5V and 1A.
does it mean that any of them is good? is it possible to charge it even faster?
the charging speed is pretty much ok I think.

QC3 will not do anything but charge at standard speeds. This device is power delivery. QC4 will be compatible with power delivery, but good luck finding a QC4 charger.

No. It comes with a Power Delivery charger, the phone is a Power Delivery device.
QC3 and below will charge at a standard (slower) speed. QC4 is compatible with QC and Power Delivery - but, at this time there is no QC4 chargers, oddly.

The OP said that using the charger that came with the Pixel 2xl still charged no faster than the older ones (5v 1A) or did I misread the post?

He said many other things, too.
I think constantly charging with the screen off helps with the charging speed. It shouldn't, but reading other threads has me thinking this. I also, think his phone is faulty.
He also said he thinks the speed is ok.

For the heck of it, I tried the OEM charger with the Ampere app, and it was showing basically 5v at 1 amp. Tried the usb A port on my power strip that does 5v at 2.4 amps, and it read the same 5V at 1 amp. The 1 amp port on the power strip gave a reading closer to 4v at 1 amp.
Not sure what the data source is for the app because the OEM charger definitely charges quickly. I have no doubt the OEM is doing 9 volts at 2 amps. Or something definitely higher than 5v at 2.4 amps. I am assuming it is a net figure being measured somewhere not in the line from the port, since it'll also show the discharge when unplugged. So this is not the power coming into the phone.

So as far as I checked, everything is charging well.
The problem is that if you will install few other Ampere measuring programs, some will reveal that they don't have access to the sensor of the phone so the data isn't accurate.
so, we can hope it's ok. sadly I can't find anywhere a physical USB-C Ampere meter to buy for now.

Nathan k over on Google+ has done some tests with the new pixel 2xl. You can see his results there, and yes, the charge rate absolutely slows down with screen on.

Yeah, I would assume slower rate with screen on, but would it reduce from 9 volts at 2 amps from the OEM charger, to showing only 5 volts at 1 amp? Mine does seem to slow noticeably, but that'd be a big change. Unless it specifically drops the incoming power down when the screen goes on.
I think someone needs to throw down the $25 to get an in line USB C meter to just measure. I almost did yesterday, but got too busy to read the reviews of the ones available.

does anyone know if using QC3 or say an older Nexus 6p charger really hurts the Pixel 2 XL? I keep hearing X and Y chargers shouldnt be used on the Pixel 2 XL..but does it really matter? is the only downside slower charging? or can you really hurt the battery?

What is your average charging time with stock charger?

The title says all. Mention if you are using other chargers too like qc 4 or wireless charger please.

Originál cestovní nabíječka doma 2-2.5h v práci 3h a v garáži hodně pod 2h spíš lehce přes hodinu.
