[Q] Fast Charger for Car

Hi All,
I'm looking for a good dual USB FAST charger that works with my Galaxy S. I need it to go in my truck. I purchased a Macally 10W dual USB CARUSB10, but the Galaxy recognizes it as a regular USB port. Apparently, Apple products must use a different way to determine if the port can provide the amperage.
Ideally, I'd like one that can fast charge Apple and non-Apple products. So, something that plugs into a cigarette outlet, has two USB ports, and will fast charge about anything.
Thoughts?
Thanks!!
Riley

Galaxian kernel does something similar to what you are looking for

REVIEW RAVPower 2.1A Dual Port USB Wall Charger

http://www.amazon.com/RAVPower®-Cha...+5.0V+2.1A+for+iPad,iPhone,Smart+Phone（White)
just bought one for only $9.50 and its really nice to have because of the duel usb ports, i travel alot so it really comes in handy when charging my phone and camera at same time plus it can also charge my nexus 10 fast if only using 1 port. 1 Ampere max. port for Mobile phones. (Share 2A when both ports in use) and i also like the fact that it's wall outlet prongs retract into the unit itself for added safety. and for more safety when charging its has over-heated, over-current, over-charging protection.plug it into the wall and charge just about any mobile device from 5,Iphone 4/4S,Ipod Touch,Kindle Fire,iPad Mini, The New iPad, iPad 2; Samsung Galaxy S4, S3, Note 2, Note n7000;Kindle Touch to even blackberry. lol

Galaxy s5 2.1A car charger not working

I recently got a new Galaxy s5 on contract. I've heard that the galaxy s5 supports fast charging with a 2.1A charger. I bought a 2.1A car charger online, but the charger doesn't work when I connect it via a regular micro-USB cable to my phone. My brother's Galaxy s4 mini charges fine on it.
I was reading something on another post mentioning the need to modify the cable itself?
Any suggestions? I have another USB car charger for an iPad, and this charger also doesn't seem to work, whereas my old 1A car charger does work, but charges very slowly.

Buy this one Maxboost car charger at Amazon or e-bay. Best of the best.

I was hoping to find a solution that doesn't involve buying a new charger

I havent tested with my Galaxy S5, but previously I had "noname" chargers and cables, and they worked fine with my HTC One S, but didnt work with my GF's Galaxy S3.
Samsung might have made devices more "sensetive" to crap products. Try different cable (try original USB cable that came with ur phone and the charger you bought).

I tried original USB but to no avail. Perhaps this has something to do with this:

The problem is most generic car chargers are designed to work with Apple products. Apple uses a non-standard way of telling their devices essentially "hey, I'm a charger." This makes "standard" devices not recognize the charger properly. The device tends to think it's plugged into a computer and only draw around 500mAh.
You can convert a USB cable into a charging cable by shorting the data pins (on the device side), or you can buy charging only cables. I've been using these cables on my S2, and now my S5: http://amzn.com/B007F1DV76 . I used a Galaxy Charging app to verify charging rate and it indicated 1.2A on both the Samsung wall-wart and cable as well as my Scosche 2.1A car charger w/ charging only cable.

Why is this? When 4 out of 5 devices are built on Android? http://tinyurl.com/qxpnyoh
I am so irritated at not having access to quality accessories for my devices. Take for example I wanted a set of great sounding headphones that controlled my mic, my tracks, etc. But, you won't find it other than Samsung's own that come with the phone. I had a great sounding pair of Seinnheisers but could not go back and forward on tracks. I plugged it into my ancient Ipod 5th gen classic and worked beautifully! For $80 I should get full functionality for my S4 or S5! My only choice is the LG Tones. Which are awesome but if my battery dies then no music or calls for me!
Frustrated!

My Klipsch earphones work perfectly changing tracks with with the inline remote.
Also my 2.1A charging won't charge my GS5 but it'll charge a GS4 and my Galaxy Exhilarate.

I followed these instructions and my car charger now charges my gs5:

Anyone wanting to know how to fast charge using the usb port on your pc/laptop?
This usually takes ages compared to charging via mains lead, the hack itself is quite simple and involves modifying the usb cable
my results are as follows (these can vary depending on what you are using your phone for, what background apps running, etc.
charging with mains lead :
4.2v
998mah
mains ac
charging with STANDARD usb lead:
422mah
3.999v
standard usb
and finally the MODIFIED usb lead hack:
4.161v
782mah
usb hack
as you can see it is a 53% increase in charging compared to standard usb charging mah, and slightly under mains ac charging mah,
as my phone is always plugged in at my work pc or home pc or laptop or whatever this works out good
TUT:
use at your own risk this is for information purposes only and I hold no responsibility to any damage that may arise
using a micro usb cable (charging cable for htc phones)
cut it using a pliers half way through the cable
using pliers again cut away the thick black wiring, the red and black small wiring, and white and green wiring
from the usb port end to the microusb connect the black and red cables together so they join
from the microusb end short out the white and green cables together
from the usb port end leave the white and green cables, do not touch these
use insulation tape/solder to clean it up and then your cable is ready
I will make a mod for car chargers also soon
see attached image showing which wires to cut and which to join up and which to leave alone, if this helped you in anyway (it should help you ) then please hit the thanks button
this mod will trick your pc/laptop/htc into thinking that it is not a pc usb cable and will allow higher currents and voltage to your phone
you can check this with current widget from market place
once this mod is done, you cannot use the same cable again for pc/usb tethering or usb disk drive, only cable can be used for charging

Which cable are you using with that charger?

I also bought a charger (Rapid USB Car Charger, http://bit.ly/VrK8s2) that was able to charge up to 2.1 A, but when I connect my Nexus 5 (with OEM cable), I charge with speed of 500 mA. I expected least 1 A.
I'm not amused at all! End users shouldn't have to deal with this nonsense. This should work out of the box!
I have two alternative:
1. Buy this charging cable.
2. Change kernel to trick the phone to draw more power from the USB port.

This 2A charger from PowerGen has dual ports that are actually labeled for Apple and "Standard" charging. PowerGen 2.4Amps / 12W Dual USB Car charger Designed for Apple and Android Devices http://amzn.com/B006SU0SX0
Works fine with the stock cable also. I have this one in my wife's vehicle since she has an iPhone and I have a Samsung.

Can't find any online store that will ship to Sweden.

Funny, none of my old $$$ dual chargers would charge my S5 for S&G picked up a dollar tree special and it charges my S5! I give up!

i use old regular usb cables, charges about 1% per minute, works great!! (not using usb3 cables)
wtf black price!! lol. mine was about $10, purchased 2 when the s5 phones came out.

I heard that cables matter the most in charging. I always use cables that came with my phone and have had no issues charging my phone so far. Have used PowerGen and Avantek. Both charge my iPhone 5 and Samsung Galaxy S4 at full speed. High quality construction and seems pretty durable.

This car charger works flawlessly at 1800mAh, i have been using it for a few month now.

I tried at least 5 different chargers and none of them charged more then 450mAh, i was really depressed about it until i found the charger linked above. Also, the fast charging USB cable *charges on 750 - 850 mAh which is just enough to not let your phone loose battery percentage while the navigation is turned on.

Hello,
I think you should go for a special Samsung Galaxy S5 Charger[/URL] car charger .I found a large variety of car chargers but you should look if it is the right watts that your S5 needs,maybe this is the reason why your brother phone charged and yours not

Looking for car charger that would actually charge Tab S.

None of my cigarette lighter chargers do the charging. iPad Air is fine, iPad mini second generation is fine, Note 3 is fine, but Galaxy Tab S 8.4 does not charge. The output from the charger is 2.1 amp, after checking Samsung web site specs, tablet need 3.8 amp. Anybody can recommend any charger that will do the job?

Sony currently does not have a car charger for the Tablet – this may possibly change in the future.
I the meantime you could consider an AC/DC inverter – somewhat bulky but does the job used in conjunction with your power adaptor.

I'm sure you can find a cigarette adapter that has a couple of USB ports on it that has that high of amperage. That's how I charge mine. As a matter of fact, that's how I charge all my devices now instead of using the "original" cigarette charger with one connector and the coil wire. I discovered that most of those are 1.2 amps, now you can find some 2.1 amps, but if you're using your device as it's hooked up, it barely gets a charge. Some of the cigarette chargers with multiple USB ports work good, but be sure you don't plug anything else in at the same time or your amperage will be cut in half.

Question USB Cable For Android Auto & Fast Charge

Could you please suggest me a Type A to Type C USB cable that can charge the phone while running android auto?
The cable I use now is the same I've been using for years with the Pixel 4 XL and it would charge the phone properly while running android auto while the same cable with the Z Flip 3 it charges the phone very slowly.

The problem may not be the cable. The Z Flip 3 downgraded the charging and data transfer on the USB port to what they used in 2017. It only accepts the old 15W "fast" charge, which translates to slower wireless and trickle charge capabilities. The Pixel 4a is from 2020, so likely already as fast as it gets.

After doing some research and reading hundreds of reviews I've just ordered this one:

this one came a close second:

If I use a different cable, it will charge as fast as the Pixel instead Android Auto won't work. That's why I think it is cable related.
@beanbean50 I think I'll buy the Anker.

Just received my cable (Belkin) and wow what a day and night difference. It's now charging at 15w instead of a measly 5w (through the PC) and can now transfer files in a fraction of the time it used to take. The cable is twice as thick as a standard cable but that's a non-issue for me.
Sounds like your old cable was only charging at 5w which isn't enough to charge and use at the same time, so you should be well pleased when your new Anker cable arrives.

I bought the Anker PowerLine II USB C to USB 3.1 and solved the problem. Now it charges pretty fast while being able to use Android Auto.
