Best car charger for ET4G?

I seem to have very slow charging times in the car. I'd like a quality car charger that has safe but fast charging times. I know some of the 2.1 A ones only work for iphones and ipads. Any recommendations? I'd prefer one that has a usb port so I can plug in a straight cable or one that comes with a straight cables. The coiled ones don't work well for my needs.
EDIT - I am very sorry - I had the wrong forum open. Moderators if you could please move this thread

I like this one, charges at 950ma which is good for a car charger. Its coiled but charges fast.

This one works well also, car and house charger. Charges at 850ma.

Search for the Palm Pre car charger on Amazon. Cheap USB charger and works great.

The Motorola one above does NOT charge at 950ma for me. It only charges at 100-300ma which is the same as USB charging, VERY slow. This sucks because it's practically useless. When I used my EVO 4G with this charger, it was charging at the ~950ma...

through Battery Monitor Widget. Also during my 30min drive to work, it'll only charge up about about 6-8%. With the EVO 4G, it'd be more along the lines of 20-30% i think.

I'm using the one I got with my original epic. I did not know they make car chargers different. I thought they were all the same charging rate.

OP made a genuine mistake and isn't an idiot, so I won't Russian Nyan Cat this thread...

I Have two of these and a whole mess of these. When a cable goes bad from being mistreated, I grab another from the glovebox and stick it in the USB slot. If you have an older device that uses mini usb (slacker G2 for instance), you can just switch out the cable. After searching around, this one seems like it would push out more charging power, though. The Belkin one doesn't have a rating and the Kensington one pushes out 2.1 amps. I think I am going to upgrade.

It's all good. I maybe we can get this moved.
Samsung Galaxy S II

You need a charger that can put out more than 700 mA and shorts the D+ and D- lines of the USB port together.
If they aren't shorted together, the phone will go into USB charger mode, which will limit current to 450 mA if you have the same charging chip as the I9100, and 400 mA if you have the same charging chip as the I777 on AT&T.
Stock current limits on the I9100 and I777 are both 650 mA.
On the I9100, the current limits can be tweaked with some kernel mods. On the 777, they are fixed in hardware. Unknown about the Sprint variant.

I was kinda looking forward to that

this is the best way to get you phone charged fast

i recently discovered that many different chargers charge at different speed not correlating to their labeled amperage,
i build a testing rig that contains a resistor at 0.1A and measured its voltage in order to give me an accurate result of the current of each setup.
i believe this will help you all buy the right charger
this is a picture of my testing rig:

thanks
cool info!

thanx for this info!!!
never thought, the cable could make any difference!
I recently realized. that an org. sam charger from amazon doesn´t power my phone up properly..... the charging process takes from 20% to 100% nearly 10 hours....
the chrager looks original but the cable doesn´t..... so i will give it a try with on org. cable

What do the values on the right of the chart represent? The charge rate of the charger?

Whoa !
Great info mate - i like such stuff more than Roms and kernel

Very cool!!!

maybe its a regional thing,
i can see that usually the original S3 does have a removable cable

The USB spec states 500ma is the max you can push over the USB interface (I think USB 3 is higher though). Most electronics will tend to honor this 500ma limit. I'm not sure if it's just common practice or an actual standard, but shorting the 2 data pins together ignifies that you are connected to an AC charger that can supply a higher amperage. By default our phones & the original SGS phones will charge at 500ma max. However if you plug in a charger with the 2 data pins shorted (our OEM chargers are like this), or short them together yourself along with a capable charger, your phone will charge at 700 or 750ma (forget which offhand).

resistor value
Do you mean a resistor with 0.1ohms not 0.1A? What resistance did you use for this setup? Very interesting and helpful information! Although, I'm very curious why a different cable would give you different power numbers. Does the charger measure resistance on the cable and then lower the maximum charge current as a result? I can't really see any other way the charger could tell which cable you are using unless the charger adds some capacitance between wires or some other discrete component.

I use the charger supplied with the Amazon Kindle Fire. That charger charges my phone really fast. I think a little faster than the stock Samsung one

Very cool. Anyway you could get your hands on an Nexus charger?

Wouldnt it be better to slow charge it like a car battery? If you trickle charge a car the battery lasts way longer than on a high amp charge. This seems to work on my extended battery I ditched the 1amp for a 700MAh and charge lasted 4 days with almost 7 hours screen time
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

yup. a slower charge is better for your battery than a fast charge. (based on what i've been reading on with battery tech)

Compact/mini charger that actually outputs 1.0a

Hi, i'm a heavy user some days, so I need a compact charger I can put on my keyring. I thought I had the perfect one of eBay for ~$3 (http://www.ebay.com.au/itm/200720521235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
However, after several tests using "Charger Timer" I figured out that it only chargers at 500ma-thus making it take a very long time to charge. The point in this charger is to provide me with a quick battery boost ad-hoc, but it's pointless as it takes 1hr20 for a full charger(stock at 1000ma takes 40 minutes)
The seller offered me a replacement, but I'm not sure whether to take it incase I wait weeks then find out its the same low-output charger.
This is a popular charger (dx, eBay)-does anyone else own it? Does it work for you at 1.0a?
Can anyone suggest a cheap alternative compact charger?

i dont know if this would work for you or not, but I just ordered the Anker Astro Slim 3 and it has two ports that will charge at 1 Amp each. It is slim enough that i have been able to charge my Galaxy S3 while using the phone and stacking the charger directly behind it. So far, i am very pleased with it. I am attaching a couple of pictures so that you can see it. I am charging my nexus 10 and my nexus S in the picture. Hope this is helpful

Thanks for that!
But I'm after something much more compact.
I'm really surprised this isn't a common thing-having it on my keyring (even if 0.5a) has been incredibly handy.
Any other suggestions?
Sent from my GT-I9305 using Tapatalk 4 Beta

Has anyone got a suggestion for me yet?
I've finally received the one I ordered, and no surprise, despite being advertised as 1a, it charges slooowly at 0.5a.
Size of it was prefect- fit nicely on my keyring and wasn't even bulky
And then after a week, it broke...

I like Anker stuff as well since I reviewed a lot of their products (in my signature link). The problem is that it sound like you are not from US, Australia from your ebay link? That is always an issue because a lot of US companies deal only with a few international amazon. You mentioned DX.com - love their products as well, reviewed a lot of their stuff, always a pleasure to deal with, and they ship to Australia without a problem.
Here is my thought about your 500mA charging. Are you sure its not a cable? Most of today's chargers are 1A-2A (all new Galaxy stuff charges at fast 2A speed) while tablets like Nexus 7 use at least 1A. So it's easy to get 1A charging speed out of most of today's chargers since they all use a common voltage/current regulator chips inside. BUT, you will LIMIT your current with usb cable. A lot of these cheap cables are designed for computers, and a common USB2.0 PC port only outputs 500mA, and cables are made out of thin wire. Thin wire will limit your current, will overheat, and will create other problems. For 2A you need to use USB cable with a thicker wires. So just look around your house for different usb cables to confirm. Usually the OEM cable that comes with your phone will be designed for max charging speed of your phone. I like buying Monoprice cables, but again not sure if they ship overseas.

At DX, look for the HTC One chargers. After lots of frustrating purchases those were the only that I could find that delivered the mentioned current.
I think you may have trouble finding one that fits your country's wall socket.

Have you tried different cables? My S3 draws anything between 0.3 and 1A from my charger depending on the cable I use.

Dual 2.1A (4.2A total) Wall Charger (US)?

This is the one I bought a few months ago, no problems ... yet

This is the one that I have been using for over a year around the world (I travel frequently for work), and have never had an issue.
Can actually support 4 simultaneous devices, and I've tested it at one point with a Galaxy S4, iPhone 5, Galaxy Note 10.1, and iPad all plugged in at once and charged all of them at the same time.
It's got dedicated ports for a ipad, samsung tablet (presumably a little more juice on these two ports), and two "universal" ports that work for most phones (I current use it with my Galaxy Tab2 and Nexus 5) so you should have no issues with both Nexuses.
Also, the size isn't too bad at all, so very portable. The only complaint -- if you can call it that -- is that the blue led is super bright. Nothing that can't be fixed with a piece of black electrical tape

I tried charging my N5 with my LG G Pad charger and the phone got really warm. Is this OK? That was at 1.7A...

I got the Limefuel dual port 4.8A/24W dual port charger and it's hooked up to two Qi chargers to charge 2 Nexus 5's and I can say these Qi chargers have never charged this quickly before. One Qi charger is the 3-coil type (which is already awesome) and even charging while using the phone it charges mad fast.
I also got the Anker 5-port 8A/40W charger which I am still testing.

No to anything with the name Samsung. The LG Optimus G Pro E980 charger plug I have is 5v 1.8amp. Get any correct USB cable and make sure the plug is at least 1.8amp, a 2amp plug will also work. I have trouble with generic car chargers that are only 1amp, they keep my phone alive but take hours to charge it and it will eventually burn up the USB cable but not harm the phone. Trial and error results.:good:

You can use an iPad charger, which is rated at 2.1mA if you have one of those. The charger I got with my phone was 1.2mA, should get at least 1.5mA rated charger for faster charging performance.

Look for a used iPad charger in your local market. It can be for the iPad 1st gen even. I've never used off-market chargers with expensive gadgets, a couple of my friends' phones were fried that way.

I have noticed, keep in mind I just got this phone so still learning it, when my battery wasn't fully charged the LED on the home button wasn't working quite right. It was working but very dim. Now that the battery is fully charged the LED is nice and bright and not dimming on me. Is this normal? A power saving feature maybe? Or could there be something wrong with the LED board underneath?
And most Ipad chargers are putting out [email protected] amps. Isn't that a bit too much?
