Faster Wall Charger (Updated with results)

Hello Everyone,
I wanted a faster and better charger for my Nexus 5. After doing some research I came up with the following possibilities:
From Amazon:
http://www.amazon.com/Tech-Armor-Charger-Watts-Black/dp/B00CD0HGDE
http://www.amazon.com/iXCC-Charger-Charging-Samsung-Package/dp/B00FCISG6K
http://www.amazon.com/EZOPower-Charger-Adapter-Smartphone-Cellphone/dp/B00EDU5X6Y
All these chargers have 2 USB ports, which they are great if you need to charge two devices at once. They will charge 2.1A from one port and 1A from the other. My problem with all these is that they are bulky and two of them have ports that come out of the back. It can be difficult to use if you want to plug your charger lets say behind your bed or similar tight places. That is one of the reasons why I don't like the stock Nexus 5 charger as the USB cable comes out of the back and its only 1.2A
From eBay:
http://www.ebay.com/itm/OEM-BlackBe...o-USB-Compatible-Phones-Tablets-/200976069483
This charger is exactly what I'm looking for because its small, the cable comes out of the side, and the output is 1.8A which is greater than the stock Nexus 5 charger. Plus at $3.99 & free shipping for a new charger is not a bad deal. Since this is an OEM Blackberry product the quality is excellent. Cable is around 7ft long.
Bought me two of them, one for the office and one for home.
Will post my results as soon as I receive the charger. Will test how much current the Nexus 5 can pull.

Won't phones and batteries only pull the number of amps they are designed to pull? I didn't think it mattered how many amps a charger could proveide as long as it has enough?

I had tablets chargers that I would use on my Nexus 4 and the phone would charge a lot faster than the stock charger that came with it. I'll do some testing and will report my conclusion once I receive it.

The Galaxy S4 charger works great and really fast.

Meh, the stock charger is 1.2A so that's what I figure the fastest it will charge.
I had an SGS3 and using my dad's Note 2's 2A charger, I was still only drawing out 1A, which is what the SGS3's charger came with.

The Nexus 5 comes with a 1.2 amp charger. I HIGHLY doubt it's actually capable of charging any faster than that (it'd be a lot of heat for such a small device).

Charging amperage is specified by the device not the charger. Value on a charger is the maximum amperage it is able to produce. This means that Nexus 4 or 5 will not get more than 1.2A even from a 2A charger.

If the phone is designed to charge at 1.2A, it will charge at 1.2A max. HOWEVER, not all chargers are 100% efficient. That means your phone may not charge at a constant 1.2A through the stock charger if it is not 100% efficient. That is why you notice faster charging speeds using a 2A charger.
If you don't believe me, get an app like battery monitor widget and look at the power input when you are charging.
This is what I use: http://www.amazon.com/Anker®-Dual-Port-Charger-Samsung-Motorola/dp/B00B8L36A6
Anker is a very good brand

My Nexus 5 charges quickly with the charger that it came with. It is 1.2A. I purchased a new car charger that is also 1.2A now. It seems to work well.

I actually just got my nexus 5 today so I can't comment on the included charger. I was talking about my old galaxy note and htc desire. There was a site that reviewed the efficiency of chargers but I forgot the name of the site.

I use my Nexus 7 charger (2A) and it charges way faster than the stock. They are only $15 on amazon too.

My HP chrome book has a charger rated at 3 amps. Charges the phone crazy fast. I remember seeing these threads and how people said it doesn't matter what the output is blah blah blah. It works. I just wonder what effect it has on the battery? I think its supposed to last longer if you charge it slowly correct?

I use nexus 7 charger. Takes around 15 min to fully charge at 70 percent

Everyone is saying "its faster" but nobody has bothered to mention what faster is.
From 15%, I saw 100% charge in just 2 hours with Qi so I think these phones charge fast in general since Qi is only 1 am output.
If we could stick to real #s going forward then this thread would have some value.
First establishing some baselines with stock charger is essential. Also remember only some fuel gauges support actual current measuring and many apps attempt to calculate current by looking at voltage over time.

Thanks...since I left my N5 charger in a hotel (!) I was having trouble finding a replacement 1.2a charger. So gave up that hunt and just got the Nexus 7 charger on Amazon.

We don't need no stinkin' science in here!
A lot of people just assume their phone is charging faster because they're using a faster charger. Placebo at work.
Folks, if you want to properly determine whether a charger over 1.2 amps is worthwhile you need to do a proper test and remove all the variables:
1. Put the phone in airplane mode and shut down all apps and services. Best if you do this from a clean factory reset so the tests are on equal footing. Any apps using the phone will draw on the battery and influence the test negatively for that charger.
2. Up to 15 minute charging variances are normal. It's a chemical reaction inside of the battery, it's not going to be that consistent.
3. Make sure to charge from the exact same percentage level.
4. REPEAT THE TEST at least 3 times. If the test shows dramatic outliers, perform extra tests and make sure the test is consistent.
Does that sound like a lot of work? Yeah, but it's the only way you can actually make an assertion that one phone charger is faster than another.

No. This is exactly what I'm talking about. I charge my phone all the time. And the second I used this charger and consistently from then on the phones charges about 1/3 faster. I really don't care what is "supposed" to happen. It just works. I get my charger back on Friday and I will prove it. The battery usage shows a giant spike. Upwards compared to the more gradual spike with the stock charger. My Google edition HTC one used to barely charge while playing games with the stock charger and now it charges as fast as stock when I wasn't even using it.

The HTC One's stock charger was only 1 amp, not 1.2 amps. It was clearly capable of charging faster, this phone not so much.

Quick Charge 2.0 Poll

Sooo I just copped the Aukey 18W charger and I think it charges faster than the stock LG charger but I'm not sure. Isn't the phone supposed to notify me if QC has activated? I tried it on my G3 and it doesn't even show on that either. Does this thing even work in this? Also, main part of this thread was to start a poll on what you guys think the most effective QC is. Check out the poll.

A QC 2.0 charger will be about 20% faster than stock. Doesn't matter which charger you use. There are several good ones. And several threads on this already.

There obviously are but that wasn't my question. I asked which is effective for the G4 along with a poll. You answered nothing. Read the OP before commenting please.

I've tried every one you have listed plus the ZeroLemon and a Samsung quick charger and they all perform the same, a 20% increase over stock just like I mentioned in my 1st post.

Now this is a helpful comment right here. Thanks. I almost wasted my money buying a different one.

I took a chance at this no-name Chinese Quickcharge 2.0 charger on eBay because Aukey refuses to ship internationally from Amazon, and I was pretty skeptical but this thing actually works. No pops or sizzle sounds emanating from it and it charges much faster than the one that came with the phone.

I just recently bought an 18w Anker quick charge wall charger and it works great. It's faster than stock and doesn't make any noises like the one that came with my phone. What I like about this one is there is a light that turns from blue to green when it recognizes a device that supports quick charge (signifying that it is charging at higher volts). So far I am very pleased with this purchase, though I imagine it is just as fast as most other quick chargers out there. ?

Works great with Samsung Adaptive Quick charge... Also works much better with V10b-EUR-XX than V10a...

I read here: http://www.phonearena.com/news/The-LG-G4s-battery-recharges-23-faster-with-a-QuickCharge-2.0-charger...-or-a-Samsung-rapid-charger_id69692
And it said, that using the "QC2.0-enabled Motorola Turbo charger" it charged the G4 from flat, in 98 minutes.
It also said, that using the "Rapid Charger included with the Samsung Galaxy S6" it charged the G4 from flat, in 99 minutes.
So to me, that equals near enough makes no difference, 1% per minute of charging.
The Anker PowerIQ chargers also charge the G4 at the same pace, from flat to full in around 99 minutes. In my test, I was connected to wifi, and I used the phone as little as possible, but when I did start using it, of course it immediately started charging a lot slower. I have heard that it deliberately does this to avoid too much heat being generated, I think that was a post on here somewhere, but I'm not sure if that's true or not.
I did tweet LG UK to ask if the G4 supports the 9V tier of quick charge 2.0 , but have yet to get a reply.. Maybe I should ask their support instead.. (Although on that point, I don't think it does, due to the tests been performed with a proper QC 2.0 charger, which still took 99 minutes. The fact that the Anker is only 5v, yet charges at the same speed as a QC2.0 charger, certainly implies that the G4 is only using 5V even if 9V is available on the charger..)
I do want to say though how much I like the Anker products, especially the recent ones I've bought (the USB 3.0 hub with 3x PowerIQ ports, and some cables to go with it). They feel really well made, a solid bit of kit to be honest.
But anyway, hopefully this post was useful.

I've only tried the Aukey and I'm very happy with it. So much so that I picked up the 10000mah external battey as well. It also charges quite fast.

The QC spec only calls for increased charging speed from 0-60%. After that it slows and then trickle charge kicks in when it's close to 100%. Going from 99% to 100% can take 3-8 minutes in my observations.
Unless LG relaxes the heat threshold to let the phone heat up a little more, we won't ever see true QC 2.0 on this phone.

The Aukey one most definitely does not quick charge the G4. Ill link to this other thread if I can find it again, but every single person with the Aukey charger said it did not quick charge their G4's. Several of them tested with USB volt and Ammeters. The Tenergy (and by extension, the Anker quick-charger, which is a re-brand of the tenergy) seems to work at 9 volts. Its a shame, the Aukey charger is pretty darn good looking and comes in a slick package. Its very odd because the Aukey quick-charging external battery on the other hand, does just fine quick-charging the G4.

Platinum 2.0 with QQC (Qualcomm Quick Charge )
Purchased at Best Buy on 6/26 for $24.99 What I have found is that it charges faster below 70 % and about the same as LG standard above 70 %. From te comments I've read I think LG is limiting QQC to protect the phone. IMHO

Using the Samsung quick charger from my previous phone (Note 4), and it works great.

I have a "Zerolemon" brand. It works good. I have another for the car... but not sure what brand. Like always, you have to make sure you use a quality cable before it will work. Coming from the G2, I pretty much already replaced the crappy cables.

I use ZeroLemon and Motorola Turbo. Full charge from few mins to 1.5hr instead of 3-5+ hours using 1A chargers
EDIT: USB Tester shows 8.99V 1.32Amps

I just got my Tronsmart 54w 1x qc 2.0 + 3x 2.4mA car charger from amazon. Works as well as the motorola turbo wall charger. Took about 30 mins drive to work to get from 57-97%. Ampere messured approx 1970mA charge rate at start.
Impressive packaging and excellent build quality. Came with thick gauge usb cable. I got at a good price following a slickdeals post.

I don't know about you, but my phone has hit around 112 degrees F when charging. I don't think I want it getting any hotter.

hi,
i've bought a wall charger from Aukey, and a car charger from Tronsmart, both compatibles with Qualcomm Quick Charge 2
http://www.amazon.fr/dp/B00RCM0TGY/ref=pe_386181_40444391_TE_item
http://www.amazon.fr/dp/B00XW0DET4/ref=pe_386181_51767671_TE_dp_1
and with theses 2 chargers, i have the same "issue" : my H815 charges at 6V 1,10A.
Can't these chargers go upper? 7,5V, 9V, 12V?

I received a zerolemon for review promotion but I don't think I'll use it for the daily usages. It is packed in my go to bags when I need quick charging but haven't really used much since LG provided extra battery pack dying the June promotion.
That being said I've noticed about 20% faster on ZL QC.

how to get more speed charging?

hi guys,
i have two chargers,
1. output 9.0V 1.67A or 5.0V 2.0A
2. output 5.2V 2.4A
and a usb-c cable, in the cable box i find that this cable is supporting for fast charging and support to 2.4A but when i tried it with the two chargers, and test it using 'ampere' app i got max to 1010mA with both chargers adapter ! even with this value i feel it charging my mobile quickly, and in the bottom of the lock screen i see 'charging rapidly' but i want more and why the phone is not charged depending on the values in the chargers (1.67A - 2.0A - 2.4A) and cable (2.4A)

The P2XL charger is 9V, 2A or 5V, 3A. Your amperage values are too low, which may explain why you're not charging as quickly as you should be. The solution: get a charger that equals or exceeds the stock charger ratings.

You realize slow charging is better for the long-term life of the battery, right?

Considering we often get new phones every 2-3 years, you won't see much of a degradation from rapid/fast charging.
Rather, you'll see a degradation from charging from <15% to 100% (which people do often). That will be a more significant reason someones battery will lose much off its lifespan.
I wish Android would have a built in limiter. I'm sure in the next few years, both iOS and Android will.

There's nothing I can help you guys with. All I can tell you is what ratings your charger should have, based upon the information printed on the pair of chargers I received with my device when I purchased it directly from Google. If you have a genuine Google charger and the P2XL is still not charging fast, contact Google.

I thought that charging capped out at roughly 1000 mA when the screen is on to protect the battery from overheating/putting too much strain on it. Which could lead to degradation of the battery. That would explain why you only see 1010 mA on Ampere - because the screen is on. I don't think Ampere measures while the screen is off, so it is difficult to say what value it would be giving you.
That is my experience even using the stock charger that came with the phone.

maybe your opinion is right. my next experiment is from 0% to 100% with the old charger and with the stock charger, then i will see if there is a difference

There is one other thing that you must also have. The Pixel does NOT support Qualcomm Fast Charging. It uses Power Delivery, not Quickcharge Technology. So if you have a charger that is labeled QuickCharge or a Moto Turbo Charger you will NOT get fast charging from these units. It has to be a Power Delivery charger with a USB C port and the cable must be USB-IF certified. If you don't have all of that then you don't get a fast charge.

That makes sense then, it seems like everything gets more complicated every year.

I just purchased one of these from Amazon. Note that it supports Power Delivery 3.0. This unit quick charges my phone. The Moto Charger I have for my old Moto G5+ which is a Qualcomm charger will charge the phone but only at slow speeds.

25w third party charger

Hi,
what is the cheapest and best 25w third party charger for the SE 5G?
Any recommendations? Some links to amazon?
Kind regards
Oliver Benduhn

I got the Samsung 25W charger on Amazon for around $12. It came without Samsung packaging so I was sort of skeptical not to mention the price so my expectations were somewhat guarded. Came in generic packaging. Hooked it up and it works just like a legit Sammy charger. Sometimes you get lucky i guess.

65W, there are 2 USB-c plugs and a USB-a plug, 30 euros. There is a USA version 2

I just got a ugreen 30w charger, works nice.

I have been using this one- works great. https://www.amazon.com/gp/product/B081PRLC97/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

When charging with a 30W charger the S20 FE should say "super fast charging" instead of the normal "fast charging". If it doesn't then there's something wrong with your adapter/cable.

I just checked and it says "Fast Charging". Does the stock Samsung cable support 25W?

No. 30w is not 25w. It must support the appropriate specs of the 25w pd that Samsung uses. It's the same reason you can't just plug it into a 85w macbook pro charger and expect super fast charging just because 85w is a bigger number than 25w.

You can use a 30W charger on a device that supports a maximum of 25W, you can't do vice versa.

The stock cable that comes with the phone supports 15W. Use an aftermarket cable that supports 25W or above.

I'm not saying you can't charge it with a 30W. Just that 30w doesn't necessarily mean super fast charge is supported. Also "vice versa"... you sure can charge a 30w device with a 25w charger, since almost all modern devices have variable rate logic that allow a slower charge after they negotiate on a rate.

I bought this on Amazon, it support QuickCharge 3.0 and it has two additionnal charging port (one with QuickCharge and two standards).

I've ordered the Xiaomi 55W wireless charger.
when I receive it I will give a review

What do you mean? It does not working at all?
It is not charging in 15W?

It doesn't charge in 15w. It do very slow

I haven't attracted enough hate this week so allow me to throw in this thought to you all.
the higher the amperage a lithium battery is charged with, the faster that cell will "age"!
consider the inconvenience Samsung has bestowed upon you as a blessing. if you are careful and never run your battery flat, never leave it at fully charged for long periods or sitting on a charger overnight at full, you can lose fewer of the cycles that are your batteries lifespan. charging with less current helps with this too. heat is your batteries enemy and fast charging creates more of it.
you might say "why would phone manufacturers produce chargers that would damage batteries over time ?" it doesn't hurt them if you buy a new phone sooner because the battery is weak. they'd prefer that than you getting 4 years life from a phone.
if you're a tight fisted miser like me you'll want your shiny new toys to last as long as feasible... that is all.

This is 100% exactly why the do it.
Fast charging is a nice marketing point to brag about to sell their device NOW, not for it to last months and years in the future.
This is the same reason why we don't have removable batteries anymore... Why would Samsung sell you a $30 replacement battery when they can sell you a $700+ replacement phone or even warranty repair for $120 at worst.

S20 maximum safe charge?

I just bought a Snapdragon S20 FE. It has the SD865, of course.
I am posting this here since there are more users active that can share their knowledge and as far as I can read we have the same HW.
USB Power Delivery 3.0 charging- 25W support.
It comes in the box with a 15W.
I want to use it with my HTC QC 3.0 charger. HTC deviated fron the QC standard for their lineup but I haven't had any issues charging multiple devices.
As far as I know it's not OK or recommended to go above 3000 mA when charging. I always check chargers and cables (Type-C) to be sure I don't fry my ports or phones. I use the Ampere App on the Playstore.
Using the HTC QC 3.0 charger and HTC cable -I get. 3100 mA and 4.1V. I don't have the Samsung charger with me to test right now but it's the slower. These value go down as heat or % go up.
Are these values normal?

The phone's power controller won't allow excess current and actively regulates it when fast charging. If too cold it will default to slow charging in order to help protect the battery.

Thanks for your response. When I said i know it's not recommended to go above 3000 mA I was thinking of my experience with SD QC. I am not talking about OnePlus Dash Charge or other simillar custom solutions. Trying to figure out the PD 3.0 standard now. All my cables are good.

It's a mess. With Samsung the easiest way is to use their 25 watt brick and approved cable.
I may be wrong but don't think fast charging will not work with any power source; the phone controller actively communicates with the charger.
The phone controller actively regulates the charge curve throughout the charge cycle.
On the 10+ with the 25 watt brick it gains 2% @ minute in the 30-80% or so range if the temperature is within its correct parameters.
The 45 watt brick adds more on the lower end of the charge curve but as not near much as the wattage difference suggests.

I have QC chargers. I am not inclined to buy a 25W Samsung charger as I consider it a subpar product. It had to be said. After years of Fast Charging I find Samsung solution in 2020 bad. They are lagging behind OP, Xiaomi etc. But they heavily discount their phones so, here we are. Also, the Samsung cables.... but good cables are everywhere now.
Can you share your Volts and Amps from the Ampere App, used with the 25W charger in the 30-80% range?

No clue and it would vary. Might try that apk if it works on unrooted phones.
The difference once in fast charge mode isn't worth worrying about though. Takes me 10 minutes to get a 20% midrange charge.
Li's prefer short frequent midrange charge cycles.
Note: was looking that app. It looks like it needs screen on to monitor the charge.
If so that will throw off the charge curve. You can use bt and listen to Poweramp (screen off) without disrupting the curve much but screen on draws too much power.
At that point the phone will revert to slow charging.

Ampere is non-root. It shows Live data. It's not for monitoring over a long period of time. For example: I tested my 65W type C laptop charger into my HTC. Of course it went up to 3.5 Amps in 10 seconds. Pulled it off after 15 seconds. As the laptop charger is fast charge for my laptop it goes up to 5A. My phone cannot handle that.
So if you run the Ampere app and are between 20-80% at 25-35 degrees Celsius(measured at the battery sensor). It will show your charging parameters in 10-20 seconds. No problem measuring those values there.
I know 3.1 amps is not far from 3 amps and it stays that way. Maybe I am being over zealous. I don't think that 3.1 amps will ruin my phone. My experienced is based on reading about this in the early days of Type-C when HTC adopted this on the 10. It had 18W QC 3.0... in 2016. Glad I have a 15W charger in late 2020. Actually, I am glad I have a charger )).
