I bought two of these to use with my existing usb cables and wall chargers. It works great for both charging and file transfering.

there is no "right" output
most usb ports will charge up to 500mA
the stock usb wall charger is, i think 750mA, i havent looked at it in awhile since its behind my desk, but i know its not 1A
the oem nexus one wall charger (non usb) will charge up to 1A
I would only recommend a 1A charger because there's no point to use a lower amperage, it just takes that much longer to charge your phone.

Couple of good threads on this topic, both on the vibrant and the i9000 acessories thread. Lots of good info. The deal extreme chargers look promising. Waiting to hear from a person who bought a 2amp charger if the extra 1a is used by the phone especially when using gps.

well, my phone will still charge (slowly) while watching avatar, which i would assume is a pretty high load on the cpu, using the 1amp charger i got from dealextreme.
fwiw, the one i have is a 1A "HTC" wall charger thats square and lights up HTC when charging, it ****s up my screen sensitivity so i wouldnt recommend it, but it was only like four dollars so i'll live with it.

AC charger or car charger?

The charger does not dictate the amount of current given to the phone. The phone will only draw what it wants to. The charger can limit the maximum current but if the phone only asks for 700mA, a 2A charger will only provide the 700mA demanded by the phone.
I don't know what the max current our phones will use but having a larger charger will only help if the phone requests the larger current.

I'm not sure how stressful watching Avatar is from a current draw perspective. The torture test is to turn on 3G, Bluetooth, synch, GPS and run the Navigation app while driving. Some post indicate that only a true 2A charger will be able to do this w/o discharging the battery. 1A ones can only limit the discharge. Cheap ones empty quickly.
Could you check what your charge current file value is for your 1A DE charger? Make sure to use the original Samsung cable and cross check with the original Samsung charger and a USB port.
1) Use an application like ES File Manager or Astro Filemanager
2) /sys/class/power_supply/battery/batt_chg_current
Here are the 2 threads that I've found have a lot of charger info.

well, i'll come back and update with samsung usb numbers as i wont have access to it for awhile.
i checked the file when using the HTC cable plugged into my work dell and it said 850-860 after checking a a dozen times
plugged into the wall charger now and its around 700-750
is that supposed to be reporting in mA?

Yes, but I haven't heard that anyone has measured it. The numbers you are getting are consistent with what others have see. 800-900 for USB. The original Samsung 700mA charger is getting 900-1100.
If you have another Android phone try that one as well to see the differences (e.g. G1 ~300-400).

1100-1200mA

I just bought this dual usb charger so I could charge my Vibrant and my wifes blackberry. It's 2Amp (1A per port) and works great, if a little pricey, but worth it imo. I shouldn't need to buy another charger for a long time.

[Q] Non-HTC/Sprint Chargers OK?

So I have a few car and home chargers laying around that are Micro USB, just like the EVO. Is it safe to use them? I would think so since all the charging circuitry is internal to the phone. But, I figure i would double check.
Also, are there certain micro USB > Std USB cords that are designed for charging and data VS data only?

I use a Rocketfish (Best Buy) car charger in my truck and sometimes use my wife's Blackberry 9800 wall charger or USB cable and haven't had a problem at all. I remember this was a huge problem with my old Pre but I don't know if the EVO has the same issue.

I have been usin my old Blackberry's one and works perfect!

Just check the MilliAmps rating. The EVO uses some healthy juice to charge it. Most chargers will charge it slowly as generics are typically in the 500-700mA range. But they are typically safe, I use them sometimes.

Thanks for the info. I will check out the LG home and car chargers I have left over and see what they are capable of.

I use the chargers from my old LG verizon phone. They charge very fast so obviously they have enough juice. And they don't make a humming noise when at full charge like the htc oem ones that came with my evos.

I have a pointmobl car charger I bought from Radio Shack when I got the phone and I use a USB travel charger from my old Razr VE20 in my bedroom, both work great. The Razr charger is about 700mA I think, so it charges a bit slower but it still works fine. My car charger is 1A so it charges on that pretty quickly.

My EVO is quite the slut when it comes to chargers: I like it! My old HTC Universal was PI-CKY about chargers! Pretty much had to rely on a USB cable and a device.
The 500ma charger I bout with the phone back in June died a few months ago, so I think you can't expect to cheat THAT much. I have tested 4 different car chargers and they all work (rocketfish, verizon, and 2 no-name brands).

I've never heard of a cord that was data only. Never seen one either.

They are OK but watch the amperage. The HTC one is the only one providing a full 1A. Most other ones are 250-500mAh and I've seen as low as 125mAh. That means 8 times longer to charge.
I tried buying a no-name Chinese/HK 1A charger off eBay and it ended up freezing my phone anytime it was plugged in (and resuming like nothing happened when taken out.) Weirdest thing ever since I'm not sure how a charger could affect the phone that way, but be careful.
The cheapest I've seen for the official HTC one is here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150574209506
Looks legit and hopefully it's not a knockoff.

Car Charger

Having some issues where, while using Navigation on the S3, the in-car charger that I have (Generic USB adapter) only slows down the discharge, the percentage goes down.
Is there any difference in in-car chargers? do I need a more powerful one?
Grateful for any advice

Common problem with weaker chargers or USB, the latter usually charges at 500ma which is the USB standard. Get a 1000ma charger for it and you will be good to go.

Thanks for the advice

I ordered a 2 amp car charger at the time of my preorder for this reason.

Lots of USB chargers suck pretty bad, even ones rated high amp. Some give false ratings.
This one is quite often recommended here at XDA and it's the best one I've tried so far.

Battery charger that will "keep up"?

Hello guys
I have a cheap USB charger I got on eBay.
I use my phone as a dash board cam (with the screen on) and the battery decharges faster than the charger can charge it.
Will it be possible for me to find a charger that will "keep up"
Thanks a lot in advance!

it could be either the usb cable if it's not stock or damaged but it very well may be the charger, look for a little bit higher end charger (as in not the cheapest one you can find) and it should work

The specs in the item description says 500-700 mA output at 5VDC. Not only is that low output current, but most list a minimum spec, not a range. You can probably assume 500 mA output for that one, which is not enough. The battery will discharge at a higher rate than that charger can provide.
Anyway, look for one that is rated for 1 Amp (or 1000 mA) output at 5 volts. This should be sufficient. I still use my HTC 1A charger that came with my Nexus One car dock for that reason.

Samsung phones seem to have 2 charging profiles, usb gives you around 450mah and ac gives you around 650mah.
650mah still isn't enough when doing nav/bluetooth streaming, until samsung starts using a full amp for charging you will never have a charger that will keep up.

motorola fast charger
you can use this one:
Search for "Motorola Vehicle Power Adapter micro-USB Rapid Rate Charger" on Amazon
I have been using this for quite a while now on Nexus 7, its just awesome. It has an output of 950+mah which would be enough for Nexus 7.

I used this Griffin-Powerjolt. Found it at walmart, and took it apart and soldered the two middle pins. But found my info here on XDA, but cant seam to find the thread. And I can play games, stream music, etc, and my charger keeps up and charges fine. But this post sums up your question.
Also I'm on AOKP JB and when I was on there ICS roms they have the charging mod so even when I had a cheap-o 500mah charger it saw it as an AC charger and charged at AC charge speed. I think also Cyanogenmod has implemented this also, but im not sure.

+1 for the Motorola charger recommended earlier. It puts out 950ma so the phone will read charging via 'AC' rather than 'USB'. Charges quick and will be able to keep up with BT and GPS navigation. Here is a direct link:
http://www.amazon.com/Motorola-Vehi...Charger/dp/tech-data/B000S5Q9CA/ref=de_a_smtd
I've been using it with all of my Android devices and works very well. Great quality as well. Highly recommend!

I use the 2A Amazon branded charger. You'll want to set it in fast charge, because the phone thinks it is a usb charger. You can open it and short the pins, if you want.

Actual current draw (aka...how fast your phone charges) is not determined by the charger but rather by the phone itself. The ratings on the chargers is what they are capable of, but will be dependent on the device. People would be frying devices all the time by using one device with anothers charging cable that has a totally different output if it was determined by the charger alone.

x3 on this charger. Have used it for the last couple of Android phones as well. Work fantastically with my Nexus streaming music via bluetooth to my car stereo. Never has a problem keeping up.

I'm using my N1 charger still too. Keeps up with nav, stream music, and max brightness. I don't use BT, but otherwise I always gain quite a bit of charge.

oh in another way, you could install a custom kernel and enable fast charging, works for me though.

I bought 2 of these charging only cables. They work perfect, full "AC" charge through any car charger port.
http://www.amazon.com/gp/product/B007F1DV76/ref=oh_details_o02_s00_i00
Put one in my car and my GFs car.
The problem is a "USB" charger spec doesn't allow for the higher voltage charging under most situations. Any cable that does provide the full "AC" charge is a 'non-USB compliant' charger (or something like that), thus, the cable I listed above doesn't say "USB" charger. That is a very brief explanation.

That works fine but I heard it uses your battery faster.

car charger?

I had an ATT branded iphone charger with usb port. When i plug in a usb cable and try to charge my htc on in the car it complains it cannot charge at full speed. What brand/make car charger will get me a normal charge in the car?

I grabbed this one here: http://www.newegg.com/Product/Product.aspx?Item=9SIA07R03A7077
Just received it a few days ago, haven't been able to fully test it, but it seems to be just fine.

Many car chargers just don't put out enough juice - especially older carrier branded ones (ie: cheaply made and sold at a premium). I'd be curious to know the rated output of yours.
The wall charger that ships with the phone is rated at 1 amp output. I've used a 500mA charger and haven't seen that message, though it does charge noticeably slower (as you would expect, with half the current). I don't know the specs on the charger that peteschlabar linked to, but you can find hundreds of chargers on Amazon or Newegg that are rated at or above 1A for a few bucks.

Well I didn't look at the specs of the charger I linked, but I was able to use it the other day while using my phone as a GPS. Battery level started at 94%, and was up to 96% about 1 hour later while using the charger and GPS nav with google maps for the entire hour. I'm completely stock, and the phone gets pretty toasty while charging.
But, main point - the charger seems to work just fine, keeping the phone charging upwards while in use.

Ahhh the joys of having an actual power outlet in your car. I don't have to worry about such things!
But my truck doesn't have that, so for my truck I bought the usb one that goes in the lighter, and it's powerful enough to charge an iPad, it's Belkin brand and it charges my phone very nicely, doesn't seem to be any slower than the house charger.

The wall charger that ships with this phone is the same, albeit slightly updated, model as the one that shipped with the original HTC Droid Incredible 3½ years ago, which I still use to charge my phones. They're both model number TC U250 with 5V-1A output and both have the same 100-240V~200mA input. The part numbers are different, though, and they're cosmetically different on the back with extra certifications on the newer one, and they also added Spanish and Chinese translations to the English.
I still use the same Verizon-branded car charger in my car from when I originally bought my Incredible, and if anything, it charges this phone faster than it did my Incredible and Incredible 4G. It went from 40-something percent to fully charged in about an hour of driving the other day with intermittent use. I was pleasantly surprised to see that.
