Fast car and home chargers (full 1 amp)?

So I bought a car usb charger that claimed it was rated at 1 amp. Using both my blackberry and HTC oem usb cables it will only show up as a USB charger (500ma).
This is not exactly enough to charge the phone while using 3g, gps, full screen brightness, etc. I'm looking for a good confirmed 1 amp hardwire (not using a usb cable) car charger and home charger. I used my sisters Samsung charger (rated at 700ma) and it charged it quicker than with the OEM htc charger.
And I would like to try and get ones that are confirmed to show up as fully charging the phone. I would appreciate some insight

And now that I think about it,
I would like to be able to use my Amazon prime for a change, so amazon links would be nice

I went through a few different car chargers, so I can help you out here. I bought the Belkin car charger recommended here in another thread, low profile and rated at 1A, but my phone only recognized it as USB and charging was fairly slow, extended road trips using video recording and navigation while plugged in would drain my battery over time.
I used my friend's palm pre home charger and it worked very well, so I went on to Amazon and bought the "palm vehicle charger". The one I got in the mail (from Park Deals) was DOA, wouldn't turn on at all (I emailed Park Deals and they sent me a new replacement free of charge, didn't even have me ship back the defective one). I called the local radio shacks and found one in stock at $9.99 (radio shack isn't carrying palm anymore, so the accessories are on closeout but hard to find in stock). Works like a charm, the phone recognizes as AC charging, the phone still charges while running navi or recording video.
My friend got a cheapo car kit on ebay, came with rubberized case, mount that fits the evo with the same case on, and a cheap unlabeled car charger with a bungie type cord. I tried this on my phone, my evo recognizes it as AC also, so I assume it would charge well if it's rated at 1A. I've seen several other cheapo car chargers rated at 1A as well.
Another thread here on XDA says that if you modify your charger/cable by altering the middle data pins you can get the phone to believe the usb port is plugged into the wall and draw full current from the charger. I tried covering the two middle pins with a piece of paper and plugging it in, but this didn't work for me. The other methods involved shorting the two data pins together, I didn't really want to waste a cable or mess up a charger and potentially my phone so I just bought a different charger. Another thread mentioned buying a specific rocketfish usb cable had a similar effect.

That was me on both accounts. Love my rocket fish cable. Bought the 12v/usb converter for the car and whether or not i use the pc or car to charge, it shows as ac charger on the phone. I use this cable on all my pc's as well as the usb outlet in my vehicle.

This is the charger that I bought from amazon. It shows up as charging from AC (instead of USB) charging. It's available for Amazon Prime for under $6:
The Motorola P513 micro-usb charger.

Ok so I ended up with the Moto 513 charger as well (950ma rated)

How fast does it charge?

One the 2.1 amp port, the Evo only charges at 1 amp. The Evo doesn't charge any faster with this charger than any other 1 amp charger.

Gotcha, thanks for the info.
I just ordered a Rocketfish cable. We'll see how that works.
Would be nice if they made a Y-cable to get 1amp from 2 USB ports in a PC. I mean, I know they MAKE cables like this but I read somewhere that HTC phones were designed to still only charge at 500mAh even with one of those.
Dunno.

It depends on what you're using as a charging source. When usb charging on my home pc or car, it's AC charging at 1 amp.. But if I'm charging with my Energizer external battery, it's only USB charging at 0.5 amp. This is using the same usb cable.

iGo
Would anyone happen to know what an iGo tip (A97) delivers? I am trying to rig up a custom solution that is hard-wired, but uses iGo tips so I don't have to use the cigarette lighter plug and I have the flexibility at the corner of my windshield to swap tips for different devices.
Right now, I have a 4-port USB hub installed under the dash that is 12v powered. I then use a proprietary iGo cable that uses a standard PC style USB connector on one end and then terminates into an iGo tip connector at the other end. That USB cable runs up to the corner of the windshield so I can swap tips at will.
If I use the iGo A97 tip on their cigarette lighter adapter, it seems to charge, but I am not sure at what rate. If I try to use the A97 tip on the USB hub, it charges for about 2 seconds, and then the light goes out. The Evo does not seem to like the custom arrangement, yet all my other micro usb devices do not seem to have any issues and charge just fine...
Thanks,

I can attest to the Moto 513 working fine - it has served me very well on my Evo and the Treo Pro before it.
Unfortunately it is a big ass charger though - wish there was a good micro option.

How do u determine how much power its actually charging at or if its not using the full 1amp rating?

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).

[Q] Car Air Vent Holder / 2A Cigarette Charger

Hello,
I had both these items with my old i9000 which I included when I sold it.
Looking to get a fitted air vent holder for my dashboard, as well as a car charger.
Based on past experience with the i9000, the car charger needs to be a 2A charger so I can charge the phone faster, as well as have it keep charging with the screen on for navigation. (and yes, I am aware a higher amperage could potentially wear the battery, happy to take the risk )
I got the original 2A charger from dealsextreme, but I can only see weaker/crappier chargers for sale on there at the moment. A brief search of ebay hasnt shown any moulded/fitted holders yet.
Ideas?

The official Samsung car charger CAD300Ube is at 0.7amps. I've seen aftermarket chargers at 1a but I havent seen any at 2 amps

I just picked up the Rockfish premium charger that is 2A. Haven't true it yet though.

I got a dual-port car charger from dealextreme and plugged a USB cable into the "ipad" port. It charges my SGS2 well and I do not notice any battery drain while I'm on a road trip using the SGS2 as GPS navigator. Well worth the $2 I paid for it.

I used one of these on my i9000 and will be getting one for my i9001

I bought a supposed 2 amp charger from deal extreme a while back. It wasn't 2amp. If you get one, test it to see what it actually puts through. The one I got was only .5 amp even though it was advertised as 2 amp.

How to check amp output? I have a 1A charger which can't charge my phone while navigating. Might buy another charger but first want to check if it isn't limited by the phone itself.

When I did it, it was on a Touch HD. I ran a couple of different battery monitor programs to see what it was pulling in. I found that almost every car charger (about 8 or 9 ) I tried was only 0.5 amp...some claimed 1amp some claimed 2amp, most claimed 0.5.

Thanks a lot.

ANY charger that puts out 1000mA will work with it. Motorola makes "travel" wall chargers that sometimes go on sale for a buck, and have the plug folding into them so it takes less space in a bag. As long as it has a micro-USB plug or takes your USB cable, it will work, does not have to be specific for the phone.
The whole idea of microUSB chargers is part of a larger EU plan to allow for standard chargers with microUSB tips, so you can replace your cell phone but "never" have to replace the wall wart for it.
Just check the power output, most of the Motorola chargers put out 1000mA now because some phones with big batteries (like the Atrix) can use that power to charger quickly. Lower power rating, longer charge times.

You read my mind,
It was just the info I wanted to know.
Thanks.

Bear in mind though, not all micro usb chargers work on atrix. I have a few that dont work but work fine on my other stuff. Im not sure why though. I have an external battery that worked with my nexus one but not my atrix.
I voided my warranty.

The one that comes with the phone in the US is 800ma actually. But as you said, 1000ma would charge it faster.

My atrix charger died so I'm currently using a blackberry charger with 750ma output. The iphone charger works too but it's a slower charge.

Whaddayaknow. The one supplied with my phone says 850mA, the one supplied with my bt earbud is 1000mA. Maybe someone at Motorola is paying attention to profits.<G>
But this is all part of why he industry is moving to standard chargers and why "all" standard chargers should work with standard phones. If a charger doesn't work with this phone, odds are it is too low power or simply a cheap piece of Chinese quality control which has one or more broken contacts in it.
I've gotten USB cables that have the same problem, charge or data not both. that isn't by design but at least one of the four wires in them was broken. Cheap cables is cheap cables--and I've seen cheap cables shipped as OEM from brand names.
Like cables from WD and possibly Moto that have the USB log on the wrong side of the plug--which means they are not entitled to use the logo at all, and the maker does not understand the USB spec.

If you live near a hotel, walk in and say that you left your phone charger in one of the rooms. They usually have boxes of forgotten chargers.

Thanks all for your help.
I started using lg micro USB charger which gives 700 ma.
Will get original one as well.
Thanks again.

I saw this Belkin charger and says 5V and 1A charging capacity. I read that S3 maximum charging is 1A , so will this charger work ? or does 5V is not enough ? or go for 2A ?
Also does USB cable matter in charging ?

the usb cable makes all the difference.. ive used cheap ebay cables and they dont charge quite as good as oem or the mediabridge hi-speed i have.

I have just bought a couple of these cables:
http://www.amazon.co.uk/gp/product/B00FAAHT0E/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
and one of these chargers:
http://www.amazon.co.uk/gp/product/B00D82O68Y/ref=oh_details_o02_s00_i01?ie=UTF8&psc=1
as my Belkin 1A wasn't really as adequate as it could have been.
The cables may be a bit over-kill (and a tad pricey, but I took up the 30 day free Amazon Prime trial so got free next day delivery), but as a combo they work admirably and can cope with charging my S3 and my Nexus 7 (which needs 2A) simultaneously.

Can you guys suggest a brand which is available all over world.. both listed items are not available in india. And Cant spend so much too

USB is digital (except for power). Anything a bit pricier than the cheapest cable will do.

Get a cable like this, with a charger that provides 2.1a out of a single port. If you're on a custom kernel that allows you to change incoming amperage, you don't need the dedicated cable.

Where do people get the idea that a USB cable is gonna make a difference for charging your phone??
I've used ebay, dollar store type cables my whole life and have never had a problem other than cheap build quality where the cable doesn't last very long. It still passed the same power or signal as any well known and overpriced branded cable.
I assume these people are the same suckers who buy $100 Monster HDMI cables that work the same as $10 ebay or monoprice stuff.

Be careful with those "mini" car chargers. The cheap price is daunting, but I bought a package that came with 2 with retractable USB cords for only 5 US dollars.
The adapter would not stay firmly in the car and pull out whenever I tried to extend the cord to plug in my phone, and my phone's battery decreased while plugged in...
While this could've been a car issue, I'd just use caution. Instead I purchased a regular sized one with a retractable USB built in for only 8 dollars, I'll link you if you're interested. Good luck!
