I am looking for best car charger, my phone will be all day on in the car, and I am looking for best solution for charging in the car, and fastest.
I found few good chargers but not sure are they support quick charge
Samsung OEM ECA-U21CBE Micro-USB 2-Amp Rapid In-Car Power Charger
and
Car Charger, iOttie RapidVolt 5Amp/25-Watt Dual Port USB Car Charger
Or is there some third better solution? Sorry I can't post links
thank you
anything above 2A is consider fast/rapid charge and barely any difference than the "quick charge" not to mention, saving a few mintues might do more harm than good to your replaceable battery.. at 2A, the phone will go from 6-10% battery to 50% in about 25 minutes.

I have the Anker and would buy it again, and has tons of positive reviews..
Thank you, what about Verizon Quick Charge 2.0?
I have used Verizon QUALCOMM version and would recommend the quick charge version if you want to take advantage of the quick charge. If time to charge I not an issue then obviously any high amp charger like the units cited above such as iottie would work
Is quick charge healthy for battery in my case? Or maybe should I get slower one?
I am using the Airdock.
While I can't say I loved it with the S5 (was falling off) the flat back of the Edge fits perfectly on it so I'm much happier with it.
Fun streaming video, back passengers can watch video off of it with the car speakers...
works well.

faster charging will always put a bit more wear on battery than charging at a slower rate. most people here will probably swap devices often so probably doesn't matter for them. if you plan to keep your device for a few years and want max battery life then maybe use a 5V 2A charger instead (one that i've linked to above).
2A is still "fast charge" the only difference is it's Quick Charge 1.0 which is at 5 Volts compared to Quick Charge 2.0 that runs at 9 Volts.
better example:
Quick Charge 1.0 - 5V @ 2A (5V * 2A) = 10 Watts of power
If your phone is at around 8-10% you'll get to about 50% charge in about 30 minutes.
Quick Charge 2.0 - 9V @ 1.7A (9V * 1.7A) = 15 Watts of power (up to 12V * 3A = 36 watts for some tablets)
If your phone is at around 8-10% you'll get to about 50% charge in about 20-25 minutes.
Quick Charge 2.0 will only be a little bit faster once the battery gets to around 50-60%, then it will throttle down to Quick Charge 1.0 rates to keep the battery from getting too hot and causing excessive wear.
All Quick Charge 2.0 devices are also backwards compatible with Quick Charge 1.0, meaning that you can use a Quick Charge 2.0 device with a Quick Charge 1.0 supply, and visa versa.
In short: Quick Charge 2.0 will only save you about 15 minutes to completely charge your phone compared to the normal 5V @ 2A chargers.
Get Verizons branded car charger with fast charge. Workscexcellent, and AND has a little flashlight right above the micro charge plug, which comes in super handy in dark car. Very well made.

Thats not true, Yes its better
if you want Fast charge it has to have 9v out
others have 5v out even tho some have a 2.4amp out not a fast rapid charger
Good Car charger

I bought this one. Didn't fully test yet but when I plug this, it says "fast charging". It would be better if this has light notification. But it's good that it charges fast.
So few days ago got the phone , but always charged it through USB port. Now finally tried turbo charger and it definitely isn't "turbo". I know most of those Turbo claims what I saw were just selling strategy , but I'm pretty sure I'm not even getting 1% - 1 minute. Latest Marshmallow OTA.
So , on a relatively new battery , how fast does your phones charge ? You can write with phone turned off and on..
Also looking at the charger it says for output :
Standard output :5V =1.6A
Turbo output :9v=1.6A
Turbo2 output :12v = 1.2A
This deosn't make any sense to me, while raising volts may solve some power losses through cable , amps are what charges your phone faster or slower , and 1.6A , isn't really a big deal not to mention 1.2A. Reading somewhere that quick charge 2,0 supports up to 3amps draw..
I have One Plus one and it's original charger is 2.1A (quick charge 1.0 ) , with custom kernel bumped charging rate all the way up and good cable I'm seeing about 2Amps of charging in real life , or little more than 1% per minute . I was expecting motorola to charge faster or at least even , even though they are 3100 vs 3900mAh batteries.. Not to mention I can easily mod OnePlus One and get same SOT and battery overall as motorola's, while on motorola I'm stuck with stupid locked bootloader . Original idea was to sell OnePlus One because of Motorola, but I don't know now anymore..
The volts and amps listed on an electrical device are typically its max or rated output, NOT what it "always" delivers. That being said, most power supplies will deliver their rated voltage most of the time, but the current is determined by the charged device (through it's effective resistance)... so as long as you run below the rated current, you'd be fine.
Secondly, from what I'm reading, the OPO doesn't have quick-charge technology (ref: https://www.reddit.com/r/oneplus/co...lcomm_quickcharge_20/?st=ix64k1gy&sh=6d7492c9 ) so I'm not sure what you're talking about there. Again, the charger may say 2.1A, but that doesn't mean it's actually delivering that much all the time. I have a relatively old Kindle Fire with a 2.1A charger, but I know it doesn't charge very fast even with that device.
If you want to talk about Volts and Amps, you need to use actual volt/amp meters to see what you're getting.. Note, there is an app for Android (called Ampere) that claims to report amp-rates, but it also has a caveat saying that the current should not be taken as completely accurate, for various reasons.
Lastly, note that QC doesn't actually run when you are at higher charge levels... I think it's above 80% or something? After that level, it returns to "standard charging" mode for this "top-off" phase of the battery charge cycle. So, if you're seeing slow charge rates there, it's to be expected.
The Turbo has a relatively massive battery. Mine takes...somewhere upwards of 3ish hours on turbo charging to replenish.
1 hour 15 minutes
that's what it takes to go from 0 to 100% using Turbo Charger 2.0
Thank you all for answering, this is exactly why I started this thread. Already see here some interesting results!

Thanks! Actually, OnePlus ONE DOES have quick charge 1.0 which is 5v up to 2.1A. Snapdragon 801 supports quick charge 2.0 but OPO didn't implement it with phone. There are billions of topic on this at OPO forum and a lot of people done tests including myself. The problem with OPO is it's very sensitive on cable so it works best with OEM cable and it somehow recognizes it. There is app called OPO charging current so I monitored with it and synapse . Kernel setup hardware to be able to recive very max 2100mA no mather which cable. Stock ONEplus charger. Some cheap cables gave me from 300 - 600 mA max with screen on . I found at home some cable that looked cheap but said charge only, tried and it charged around 1600mA with screen on and around 1800 screen off. Later got Anker 21 AWG and results were even better , aroun 1800-1900mA screen on and close to maximum 2000mA screen off. Phone was charging 1% in less than a minute. Thought turbo can charge at same rate. After all , it's "boosted" lol.
I know it doesn't do quick charge after around 75% , I tried at 30%. Given all that , 1600mA which is maximum I see on the Motorola's charger is not something special if we disregard Voltage..

Again this is very interesting. Already here we see 2 totally different results with one being almost as double fast.. Sparksys , you are on stock charger and stock cable?
Because if you charge from 0-100 in 1h 15min, thats around 3.2Amps charging current , while our buddy Einsteindks here gets around 1.3Amps and max amp I see on "rola's charger is 1.6Amps. I'm confused now.
Also can somebody post picof stock droid turbo USB cable shipped in bundle? I think I don't have stock cable, it says right at the plug phone side "be hello". No other labels or anything..

According to your guess-timate and max rated power I see on the charger, that seems about right and realistic guess BUT there also isn't anything TURBO about it. I'ts the average charging speed of every device today (1.5A) which doesn't have any kind of quick charge option. Even quick charge 1.0 is faster with 2.1A at 5v . Thats why I opened this topic, I'm confused.
Only voltage is higher on turbo charger than let's say my OPO charger but amps are lower and voltage doesn't have that much of an impact on charging speed, amps do!
When I have my Turbo in my truck at night, and running about a dozen things at once, in addition to all the background stuff, NO 'regular' charger can keep up with the power demand, and the battery undergoes a insanely slow discharge. By itself, the battery lasts 3 or 4 hours, tops. With the turbocharger, the battery charges at a modest rate, maybe 10% per 30 minutes...while under high demand.

I encourage others to post their charging times so we can compare!

Since no other turbo users jumped in...
At the time of starting the topic I have disabled some Verizon's bloatware (completely stock, locked turbo). After reflashing completely stock FW , and with untouched software, droid really did charged turbo fast. More than 1% per minute and around 0-60% for 30min just as advertised for quick charge 2.0 . So if anyone was wondering, that should be benchmark.
On the other hand, phone is almost impossible to charge with any other type of "normal" charger..
My Turbo, running stock MM/root/Xposed with a large load of apps, will charge 20-30% per hour on a normal 1A charger, while lying on the desk with the screen off. It charges at a similar rate via Qi wireless charging. This is plenty for daily overnight charging. My usage habits are such that I usually have 20-40% battery left when I get home from work in the evening.
In a different usage case, when I play Ingress (a real battery eater, screen on + 3D animated graphics + GPS + data) the Qi charger in my car holds discharge to about 5-10% per hour.
I've never had a turbo charger to compare, but I've never found the normal charger or Qi charger to be significantly lacking.

Right, I've also used "normal" charger before. Now, I have all QuickCharge plug chargers -- but I still use Qi wireless charging every day, as does my wife.
I also plug in via USB port on my computer and it charges fine.
okay the way the turbo charging works is that it's like a tier system at very very low charge percentages it works the fastest and slows off after about 60 or 70 percent it just charges like a regular charger all the magic happens at the lower charges. another thing is that unless the cable you are using is total garbage it won't matter at all. it is all the phone and the ac adapter that do the work any variations in the cable will be negligible. I am monitoring my battery through the custom kernel (bhb27 and its app) and it says right now at 81% charge on a turbo charging that I am getting +1172.x mA if my battery was lower this value would be much much higher
lastly I recommend only using the turbo charger when you really need power quickly. if you are just plugging in your phone for the night it makes no sense and will actually be bad for your battery health. the faster it charges the more it heats up and heat is not good for the battery health when I plug my phone in at night I use a .5 amp charger and my phone says that it will need like 8 or 9 hours to charge (this may be exsessive but the quick chargers heat up my phone a lot I also use a 1 and 2 amp charger nearby
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Poco F2 Pro (Redmi K30 Pro) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
With the supplied charger and cable the charging time is very impressive ("Turbo Charge") with a normal QC3.0 charger charge time is still very good but comparable to most other QC3.0 devices.
Something to note is the device does get noticeably warm when using the supplied charger in the "Turbo Charge" mode.
Takes about an hour for me with included charger.

That's normal because you're not using it, if using while charging it will be hot as your running apps, tasks etc... at the same time. This will increase the heat as sensors will be running also.
Has anyone tried to use other cables that has the same turbo charge effect like the included cable? The included cable is too short, usually I use 2 meters long cable.
I have tried the baseus 5A 40W cable but it only support quick charging and not turbo.
I've tested charging wattage using original 33W charger and original USB cable via specialized USB tester, and I noticed it provides only 25W (about 9.6V/2.65A). It shows "Turbo Charge" indeed, but it's still only 75% efficient. Anyone care to explain this? Is this normal? I've read that only Zoom edition can be charged at 33W, so I expected non-Zoom edition will charge at least with 30W. I tried two other USB cables, and still only 25W. Later today I will try to charge it with Blitzwolf 30W PD charger and see how it goes with that one...
I haven't really tested charge speeds. So far the battery life has been exceptional and the main reason I opted for this phone without the high res screen and refresh rate, as see battery as more essential. I would much prefer charging at a slow speed to preserve battery life. A good app for this is AccuBattery. It measures how many mAh's being charged and discharged after each charge and keeps a graph. It will estimate battery health also.
Yeah I know about AccuBattery, I've been using it in the past. But a real physical tester device is always more precise. I do sw/hw development for a living so I know for a fact. Indeed, battery life is very good because optimized MIUI and pretty big battery, but it would be even better if charging speed was also up to the specs. Meanwhile I've tested charging speed using Blitzwolf 30W PD2.0 charger (K30Pro should support PD3.0 and be backward compatible), and situation is even worse - only about 15-16W at QC3.0 I believe. So no Turbo Charge was initiated. I mean 25W with original charger is still good, but I expected advertised charging speed. I'll do more tests when I catch some time.
Thats normal, because it don't charge all the time with 30W. Compare it with WARP Charge 30T it is faster. OnePlus 8 got 30W and 4300 mAh, F2 Pro is faster with bigger bettery but it's almost the same.
How old is your Blitzwolf charger?
I know it shouldn't charge @30W above 80-90%, but sure it should at 20-ish where I'm at about now. It's also not even cool to the touch, so there's no apparent reason to slow it to 25W. My Blitzwolf charger is about a year old, but I only used it couple of times, so it should be as good as new.

Batteries don't like heat but it is actively monitored and it will slow down charging when it crosses temperature threshold.
That's why I mentioned my phone is not even cool to the touch (let alone hot), so my case is not temperature related. I'll try to charge it while turned off, though it was pretty much in idle doing nothing when I did the test, ie. not stressed at all by any factor. All in all, I mean if everyone else gets 25W out of original charger, I won't bother anymore. Also, if it charges from 10-90% in around 1 hour, I won't waste any more time on this either, since it's good enough for me. I was just curious why it charges at 25W, when 30W (and 33W for Zoom edition) was advertised. Altough it wouldn't be the first time something was advertised at launch, and not achievable in real-case scenario.

Fun fact: phone doesn't charge when powered off?! That's a first. Is it just me, or am I getting too old? For the whole time I'm talking about my Redmi, not to confuse it with Poco, if that matters at all. Maybe Poco works differently.
On my Huawei device you also can not turn off an charge but this starts with Android 10.
takes about 1 hour and 20 minutes for me, I think the high temperature here, summer season, is the reason for this slow charging speed.
From 20-100% in about an hour. Few minutes less actually. Battery is big, that's all ok.
F2 turn off and are dead with 0% (can't turn on). Timer 60 min. and after 60 min. I got 96% with original charger. The phone don't turn on, like it always do.
@Burs a friend told me "on my Anker charger I only can use PD over the third usb port, with the type c port it will charge over QC 3.0 and not over PD" maybe thats why you get ~16W?
When my Redmi was turned off completey, it was hooked up to my USB tester for about a minute. I doubt it would trigger after some minutes, and only then start charging. For the whole time it was connected, I was getting 5V / 0.015A readings on the display. That's pretty much USB tester drawing the power from the phone battery, not the charger! So that would mean charging was completely disabled making the phone behave as a power bank lol. Weird enough, right?
My Blitzwolf charger has only two ports. One PD2.0 (USB-C) and one QC3.0 (USB-A). I've tried three sets of USB cables (one even 5A) on both ports, and best I could get out of it was about 15W. I think I'll have to order another one with PD3.0 and Turbo Charge compatibility.
Heh I'm planning on just using my old 1A slow chargers because they're dotted around the house and work, will probably not even plug fast charger in. Magnetic cables are just so convenient.
I have the Samsung 25w charger, and when using it it appears the phone will only either cable charge or superfast charge. It wont also fast charge. I want to maximize the battery life span of the phone, and cable charging is inconveniently slow, and I figured that fast charging would be a happy medium between that and maxing it out. I was under the impression that it's the phone that dictates the rate of charge it will accept from the brick, and the brick only determines the maximum deliverable current. If I understand correctly, we can use samsung's 45w charger, but the phone will obviously only allow 25w from it. I'm puzzled why when using the 25w charger the phone can't just accept 15w when set to only fast charge. Is this a bug?
Hi,
You might plug in your phone, Go to Parameters, Section Battery, Advanced Battery, and activate Super charge and superfast charge in order using fast and supercharge with your 45W charger !
Yes, I've done that. The 25w charger will only super fast charge, but won't just fast charge. I would have thought it could either one, whichever I have it set to do.
if you want fast charge ..... deactivate superfast charge should be the solution ! Isn't it ?
Probably a firmware/software glitch.
Fast charging will not enable if battery temp is too low.
To avoid Li plating the battery temp should be a minimum of 72°F or higher, the preferred minimum is 80°F.
Using the 45 watt brick may shorten battery life.
Fast charging with the 25 watt brick appears to do little damage.
Li's prefer brief, frequent midrange charges ie 40-65%. Avoid discharging below 30% and charging beyond 90% although 80% is a better top limit.

No, if you only activate fast charge (with superfast deactivated) and use the 25w brick, the notification in the shade says cable charging, and that takes like 2hrs to charge the phone.

That doesn't sound like fast charging is active. It should gain about 2%@minute through most of its range except the top end where it goes to about 1%@minute.
When this doesn't work correctly it's a true pain to troubleshoot. My 10+ started dropping out of fast charging prematurely. A new 25 watt brick/cable and trying a lot of other remedies still hasn't fully restored it.
I'm curious if anyone here has a 25w brick that could confirm if this behavior is present globally, or if this is something just on my device? Only activate fast charging in the battery settings, plug the phone in with the 25w charger, and look in the notification shade and see what the charge rate is tagged as. I'd be grateful if someone would confirm this.

I have noted that you practise the same charging procedures as I have done for several years (and you obviously have done as well). With my Note9 and S8 + I used to not let it drop below 40% if I can avoid it and also not go above 80%. All this is fine and most of this we all probably learned from Battery University and Isadore Buchmann. That all said, and I am really not sure if I am keeping this phone - Decision today or tomorrow - my question comes to the matter of calibration. When I received this phone some 14 days ago I charged it to 100% but thereafter did not run it down to zero but kept it above 40% the whole time. The question I put to you (and others can learn from your response) is there a need to "calibrate" the device initially (ie run down to say 10% for example once a month) as was suggested by Buchmann probably a few years ago?

That doesn't sound like fast charging is active. It should gain about 2%@minute through most of its range except the top end where it goes to about 1%@minute.
When this doesn't work correctly it's a true pain to troubleshoot. My 10+ started dropping out of fast charging prematurely. A new 25 watt brick/cable and trying a lot of other remedies still hasn't fully restored it.

You and I discussed this earlier. Do you think it is the port that has become damaged? Part of the reason for my getting the wireless charger is my Note 9 is very erratic when it comes to fast charging. Cleaning out the port with a toothbrush/compressed air. rebooting...wiping cache partition, new cable etc never truly fixed it for me. I do feel that when first plugging in the S21 ultra (before going wireless) the connection seemed a lot firmer.

I'm curious if anyone here has a 25w brick that could confirm if this behavior is present globally, or if this is something just on my device?

It does appear to be related to the Samsung 25w brick. I have the one that came with my S20U. It will "Super fast charge" my S21U no problem. If I turn off super fast charging in the phone, it only says "charging" when plugged in, and with my phone @ 65%, it said it would take well over an hour to charge (forgot the exact time). Then I took my phone w/o changing any settings to a generic 18w QC3 brick, and it said "fast charging", and said it would take 44 mins to complete.
Ive seen this same type of issue as well with 2 different chargers. One charger (45w pd) will fast charge with super turned on but not fast, notification only says fast charge. The second (39w qc3) will fast charge with regular fast charging turned on, but turning on super does nothing. Charge times are the same with both chargers on regular charging and fast, with 0 differemce between fast charging and super.

I'm as clueless as you at this point unfortunately.
My port is good, cable/charger, tried hard reset, cleared system/akp caches, did the recall thing and so on.
I'm wondering if it's a battery fault. Do older batteries go into fast charging the same as newer ones? It's almost as if it's throttling the fast charging, sometimes it's full bore then it drops out to 1%@45 seconds then to 1%@minute.
Or is it a calibration ie it thinks it's at 90% when it's only at 70%?
The only I haven't done is a factory reset, lol.
All this started one night when it was slow charged to 100%. WTF?
TFF the curse of technological Beast!
Guess I'll try recall again.

Right on. Sounds like it's not just my phone. That's a relief. It's puzzling why the phone can't also fast charge with that brick. Perhaps it's simply a bug that Samsung either never noticed, or it isn't a priority to them. It would be nice if we could take advantage of the different settings without having to have two different bricks sitting around.
I think I figured it out. The fast charging setting is for the old classic fast charger. If you connect your phone to that one, you'll see it says it's fast charging. If you don't have fast charging turned on, it'll prompt you to turn it on to use that charger at it's maximum capability. If you use one of the newer Samsung C to C bricks, it's going to do the super fast charging.
I am currently using this Baseus charging plug and get full range of charging options - fast / super fast.
Thought I would try some I have hanging around before buying a Samsung one.

XDA just covered this in their article:
Fast Charging Explained: The slowest to the fastest Fast Charging technologies
Curious about fast charging? Here's everything you need to know about fast wired charging standards and how to pick the best charger!
www.xda-developers.com
Unless a charger has USB-PD PPS they will only FAST Charge @ 18w with fast charge on (super fast on/off wont matter as it will be off). If you are getting super fast charging then you are getting the expected 25w which is totally fine and not bad for battery. You will get super fast with the samsung 25w adapter and maybe the previous series 45w adapter.
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

No huge charging improvement. It most likely will degrade the battery faster.
I use only the Samsung 25w bricks because they are known good and relatively cheap.
Just picked up a 25w brick and cable for $20.
The amount of trouble a defective charging hardware can cause means I won't consider using 3rd party chargers/cables for fast charging.
Fast charging is a nightmare to troubleshoot as I'm learning now... will see if a couple full 100-0% charge cycles get it or not.
It's time consuming and irritating.

Thanks for posting the link to that article. It clears some things up. Charging standards have become rather confusing with all the proprietary standards. This makes me feel more comfortable using the 25w super fast setting on the s21 ultra.
Hey Folks!
Is it okay to charge pixel 7 (It supports only upto 20W charging ig) with a 65W charger? Will this have any ill effects on the pixel's battery life overall the device in any way?
It should be okay. Most likely your 65W charger uses quick charge technologies and will charge your phone at higher voltage instead of high current which is good for your phone (i.e. 1.3A at 11V instead of 3A at 5V). This result in much less heat generation which is the main battery killer.
In any case, your phone will only pull what it needs (and can) from the charge.
I use the 65W of my dead OnePlus phone without issues. The phone only pull a total of 25W anyway.

Hi, thanks for the reply. "Output: 5V~20.3V=3A (Max)" is what is written on my charger. Is it okay?
there is a voltage regulator, should be fine...
I've tried m1 macbook air charger with my P7 and phone recognizes it as "charging rapidly" and been charging impressively fast!

I think it's safe. I use my 65w mac charger for my P7 and its impressively fast. The phone runs hot while charging tho so I don't use it while it charges. Haven't had or noticed any issues so far.
It doesn'n matter how fast is the charger, the phone also controls the charging speed. If the charger uses the power delivery standard (wich is used by the Pixels) you can use even a 65W one (like Oneplus 8T's warp charger; 45W as PD), charging speed will be limited at 20/23W (7/7Pro). But if you use the 65W Realme charger (wich is also a warp charger but with USB-A output and without PD support), charging speed will be limited to 10-12W.
As long the charger is high quality, you should be fine. As mentioned before, the charger and phone negotiate charge voltage and current.
