I am looking to purchase one "original" car charger for the Nexus 5, since LG do not have retails around here, thought of going for the Samsungs. Found out that Samsung have two car chargers, one for 5w and another one for 10w, the 10w one is almost twice as expensive.
Is the 5w one enough? Or should I get the 10w one?
Yes, it's enough. The 5W charger = 1A. Since the wall charger that came with your nexus is 1.2A, you'll notice that it will charge slightly slower than it does when you plug it in at home, but still way faster than USB.
9 watts at least.
Less just wont charge,The phone will just discharge slower.

The A/C adapter that comes with the Nexus 5 is only a 6W charger, so that can't be true.
This is from my experience bro.
Do not forget that watt=volt*amp (5 volts * 2.0 amp=10 watts).
Which gives us that 10 watts equal to 2 amp home wall charger or 9w which would be equal to 1.8 amp charger if you'll try a 6w charger It's just too low for the nexus it will charge up to 1.2 amp,and this is honestly not enough.
Also the Nexus 5 chargers really slow if the phone being used while charging (which in this occasion could be GPS,Music,Bluetooth),so yeah,9 watt at least.
This is interesting. So probably the 5W is enough for a slow charger and will charge slower than the Wall Charger.
10W will definitely charge faster than the wall charger.

Well I have ordered a cable to charge my nexus 5 that marked as high speed charger reachs 3A, and a wall charger that reachs the same 5V 3A
This should allow me to charge my nexus 5 with 5V and 3A as noted in the cable and the wall charger.
My question is if it would damage my device to go that high with the amperes
thanks in advance

Bumb, help me please
From a non-expert position, just what I've read over the years and my experience:
First, I highly doubt the Nexus 5 will "absorb" so much power. Usually, there is a chip that limits how much power it can take, let's say 1.5A.
Secondly, if it took all 3A, it would:
Be very damaging for the battery on the mid-term and long-term
The battery would last less hours than charged at a normal, slower pace (less A)
So I don't recommend it. But there is a lot about this on Google.

Nexus 5 can pull around 1.5-1.6 A only at max I guess. Even if you charge the phone via 3 A, it cannot pull that much. A higher rated charger will not damage the battery as long as the voltage is rated which matches with the phone's specs. Amp is pulled and not pushed, hence the N5 can pull only to the extent it can pull irrespective of the output Amp of the charger.
Electric items draw the amps they need. They can not be damaged by a high amp charger. What is dangerous is too many volts. That will ruin the device. All ways stick to the recommended voltage. I'm using 5vts and 2.1amp charger. Get the the # ampere # app from the App Store. It really shows which charger and lead is best. Leads are very important. You can use the best charger but with a rubbish lead it wont be any use. The wire in my leads is 20guage. Tyne best. I got 5 off Amazon UK They are by "Volutz". I noticed a massive difference. A out a third more power was getting through compered with cheap ones
SENT BY ENTANGLEMENT
So my friend borrowed me his charger from his phone, which is a galaxy edge. It said it was charging rapidly and omg it sure did. It was super fast. Does the N5 support any kind of fast charge? Will this break my battert?
Also attaching screenshot
Thx,
Dan
how many output amps was that charger?
I tried charger that came with Galaxy S6, which has output of 5V - 2A, and 9V - 1.7A when recognizes fast charging device. It charges my N5 from 15% to 100% in about one hour, but on lockscreen, it only says "Charging", and charges it really fast, without heating the phone, which then seems to be pretty much safe.
@tampitzel If the phone doesn't get hot to touch on the back while not used when charging (warm is ok), then it probably is safe to use.
If the screen starts to flicker, or doesn't respond well to touches (eg. while typing), that means that charger is giving too much voltage and that's bad for phone. But that mostly happens with cheap non-original chargers.
Cheers!

I will check, I didn't look to be honest, I was just baffled by fast charging
Nexus 5's OEM Charger (by LG) is rated at 1 amp - whereas the Blackberry OEM travel charger (folding plugs) is rated at 1.8 amp - been using it for a year - and, it fast charge the battery typically in 1 to 2 hours (even when it's down to 25% to 40% on heavy use for the day) with its extra long micro-usb cable. http://www.amazon.com/BlackBerry-Pr...1449956341&sr=8-6&keywords=blackberry+charger
No need for custom rom or other "tweaks" - for in-car use, a 2-amp mobile charger with a high quality micro-usb cable is the "key".
Good and beefy cable makes an improvement more than you would ever imagine!
The stock charger is rated for 1.2A not 1A.
The Nexus 5 doesn't have any kind of official fast charging. However it will allow up to a 1.8A charge rate. Plug in a 2.4A charger it won't go any higher than 1.8A. Its what the TI power circuitry is rated for.
I find it a bit strange that through coincidence that the Blackberry folding blade charger is the best (I would say perfect) charger for the N5. It was cheap and plentiful as well as high quality.
Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol
http://www.amazon.com/gp/product/B00WN86VYQ/ref=ox_sc_act_title_8?ie=UTF8&psc=1&smid=A3RPN0HBLXDN8Z
i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Wow. Good info. Thx. Now a ton with a hack to draw more amps lol. Hmmmm lolol
I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?
See how what you have now performs. The best/fully compatible would be Samsung own charger. And any decent quality cables
I use my original charger from my Samsung Galaxy Note 4 on my S22 ultra. It charges it about 90 minutes. I suspect this is the same charger as yours.
1.67amps x 9v is 15.03watts.
5.00apms x 5v is 10.00watts.
15 Watts is a nice steady rate to be charging your battery at.
45w...is really too fast if you want your battery to last more than 2 years.

45W is nothing and won't really degrade your battery much. Also, keep in mind, that batteries degrade regardless if you use them or not, they have a shelf life. So, in 2-3 years you will mostly need to replace your battery anyway if you plan to keep your phone for that long (assuming that you want the battery to be at it's "full" capacity after 2-3 years).

Even still...I'll keep slow charging my phone...knowing that it will last 5 years.
My note 4 battery outlasted the actual phone. The touch screen packed up first. The battery still lasted 6 hours screen on.
I replaced it with a Note 9. Again...the battery was fine...and original. Same story...6 hours of screen on time.
Now I have a Note 22....or S22 Ultra.
I have used the Note 4's charger for all of these phones...with my 10watt Kosee wireless charger. Even on the Note 4...with a wireless adapter.

It's still 10 Amperes into the battery.
I'm often running ~10 Amperes into my dual 224 Ampere-hour 6 Volt "golf cart" batteries.
They also weigh about 130 pounds more than your battery!

It doesn't push 10 Amperes into the battery.
PPS charging is pushing from 3.3V to 20 Volts at 2.25Amps, it's dynamic charging and it depends on the device's state (temperature of the battery, the charger, the capacity of the battery).
I'm not sure where you get this information, and not trying to be rude now but maybe you should check up on both PD and PPS charging protocols that Samsung uses before assuming it's charging at 10 amps.

1. With Galaxy S22 there is an USB-C to USB-C cable not USB-A (maybe a typo on your side). That cable is rated for the full power charge the device supports, that is 45w. It can make a difference if you are using it with a proper charger (that's the actual naming for the "wall wart"...it is called "charger" or "wall charger" btw).
2. Yes, you should get a different one if you wanna charge faster. Your actual charger is a (so called) "fast" charger with the charging power varying from 15W to 10W. Your phone supports from 25W up to 45W, that are the "ultra fast" chargers.
I'd suggest to get at least a 25W charger, also there are some extremely good Anker alternatives (even better that original Samsung chargers), look for Nano II 635 or 615 Anker chargers.
If you wanna keep your phone for an extended period (like 4-5 years or more), you might wanna activate that battery protection charge that only charges it till 85% and will preserve it for a longer period. If you switch phones after 2, even 3 years, don't bother, charge it as you like fast or slow till 100%

If the charger is rated at 45 Watts and sometimes actually delivers that:
45 Watts / (maximum) 4.3 Volt battery > 10 Amperes
Maybe they are PWM-ing it or whatever, but the peak current is > 10 Amperes.
Ok, we can subtract the efficiency of the buck converter, but it's still in that neighborhood.
What would happen if I bought and used a 65-watt charger? Would it automatically drop down to 45 watts to charge my S22 Ultra? Could it damage it, etc.?

1.Q. Yes.
2.Q. It not gonna damage it if not pushed to full 100% or discharged completely before connecting.
Sorry to hijack this thread, but is there a decent wireless charger, that will give me fast wireless charging with a Spigen powerarc arcstation pro 65w charger? I have tried about 3-4 cheap crap ones, and they all give reg wireless charging of about 22% for an hour's charge.
The S22U‘s maximum wireless charging rate is only 15 watts. I use the Spigen PowerArc ArcField 15 watt wireless charger, which is powered by a conventional charger via USB C cable and works very well charging my S22U.
Is there a difference in charging speed between an Anker Nano 3 and the official Pixel 30W charger? I bought the Nano but accubattery tells me it only charges at 17 watts while the P7P should go up to 23 watts. Should I return it and get an official Pixel charger? Or is it normal that it doesn't reach 23 watts? Adapative charging was off while charging.
Since Anker is a well known brand, I would test it another charger. It very well could just the device only pulling 17 watts at that moment. I have multiple Anker chargers, cables and hubs at work and home. I have never had a charger fail or come up short on the rapid charging.
I have Anker cables and I noticed they charge much slower than the cables that came with and are designated for these devices. Still faster than my cordless charger.
Thanks for the replies. I'm using the official Pixel cable. I think I will order a Pixel charger and see if there's a difference.
I am using an Anker Nano Pro (20w) with Anker cables and my P7P charges in just under 2 hours which is only a few minutes slower than the official 30W brick.
This is a good read https://www.androidauthority.com/google-pixel-7-charging-30w-3226058/
Thanks, that's interesting. I will let my battery deplete further and see if the wattage is higher when charging from a lower percentage like that article says.
I am sure i have read in the past the Pixel 6 Pro over the whole charge averages only 13W, if your reading is for the average and not peak wattage then maybe 17W is right
Keep in mind that maximum charge wattage will drop off if the phone is doing things at the same time. Just turning my screen on and looking at the AccuBattery charging screen takes between 1-2W and there are spikes beyond that as apps do things.
It's not worth buying expensive chargers to get the highest wattage possible as it's a negligible benefit since the average is going to be way lower than the peak anyway. Both my OnePlus 9 charger and my Anker charger seem to peak around 19.9 watts with the screen on and they both support USB PD PPS.
