[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.

TB & Chargers from Other Manufacturer's

So I have the original usb cord and plug hooked up in the bedroom to plug my TB overnight and a blackberry bold charger in the living room because its extra long. Wife and I use the living room one and take turns. Plus I have the original micro usb cable from a Droid X plugged into my PC. At work there is a community charger that we all use by the locker room that has a Motorola brand on it. No one knows who it belongs to or what phone it was made for.
Bedroom and living room chargers seem to charge at an expected rate, even while the phone is in use. Usb on the pc seems to charge faster, and the one at work seems to charge at the slowest pace ever. I left it on the charger for two hours while still using the phone and only got a 10 percent increase. WTF.
Here is the kicker tho. When I had a Droid X, I used the same setup at home and at work and all charged well. Does my TB not like to play with chargers from other manufacturer's?
Side note, near the end of this post I was interrupted by a coworker and had a ten minute conversation while my TB auto locked and sat there plugged in. When I got back to it, it jumped an extra 5 percent.

I'm pretty sure computer USB ports can only output 500mA, the stock HTC wall charger is 1A, your other chargers might be outputting less amperage which is why you're seeing slower charge times. Our TB wants 1A so it chargers pretty slow when using weaker power sources.

^this is right on. Anything less than 1A and you're going to get LONG charge times. I use an old Moto car charger which puts out 850ma and it's not too bad unless GPS and 4G are on, then it barely powers the device and chargers so if you need/want GPS and 4G you'll need a 1A car charger (I'm shopping for one now).
My question is has anyone tried anything above 1A?? There are some new car chargers that put out 2A for tablets which sounds like it could quickly charge the TB but I'm wondering if that's not too much juice.

Don't use anything above what the phone wants it could explode

[Q] Slow Charge

Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?

When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.

Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.

you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs

When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.

I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?

Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.

Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.

Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.

Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here

Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.

so this is nothing a kernel or any other tweak can fix?

Sent from my SGH-T989 using XDA Premium App

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.

the 2A chargers from BlackBerry are the best

So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

[Q] Car charger recommendations

Hello. I'm trying to pick a car charger that would work with the galaxy nexus. from what I've read so far the samsung CAD300UBEB/STD model seems to do the trick but a few review says that the battery discharges faster than the charger can charge it back under heavy usage. can anybody confirm or deny this?
and also, I would like to know if that same charger would work for a galaxy S2. I'm looking for a charger than can be used with both models because I have both phones. the listing of models in amazon website doesn't list the nexus or the S2. so I want to make sure before buying it. thanks!

I'm also interested. I was just looking at this discussion on Reddit taht goes a little more in depth

The motorola charger listed there seems work well for the nexus and also for the S2 according to amazon reviews.

I went with one of these and a USB cable, and it seems to work just fine. Also gives me a spare USB port for additional charging.

I have the Motorola one already (the one with the blue LED) when I had my Droid 3, now it can't keep up with the Nexus' power drain. Just using it moderately on 3G only in the car today had it drain 3% over 40 minutes.

not according to this guy
I have a galaxy nexus cell phone which requires probably around 1.5 Amps when using GPS. The phone does not come with the car charger. It only comes with a 2A wall charger. My temporary solution has been to use a car power inverter that has house-type outlets on it (which I already had) so that I can use the wall charger in the car. This has been working fine, but for obvious reasons, is not my desired long-term solution.
Enter this piece of crap. Now, the phone and only requires a little over 1 A with GPS. With the real two amp wall charger, I am able to both run GPS and charge the battery pretty darn fast. But, with this charger, not only can I not use GPS without draining the battery, but even when not using anything special, the battery charging times are horrendous.
Stay far, far away.

Wow... granted, I am not using a GPS, but I never really checked the charge times. I don't rely on it for a fast full-charge.. usually just plug it in on the trip home and charge as much as it can until I plug it in at home.
Thanks for the heads up.. I am gonna have to keep an eye on it now.

I've researched this pretty thoroughly, and the key question is whether or not your GN shows "AC" when you check the Battery status, or if it shows "USB."
With most car chargers, it is seen as "USB" as if it's plugged into a computer, and will draw minimal current, generally not enough to keep up. I had 2 different chargers in my cars, none of which showed as "AC". I bought and then returned the Griffin PowerJolt Dual USB Micro Charger - it also showed as only "USB."
Finally, in one of the other Android forums I've been monitoring on this issue, somebody came across this one:
HTC T-Mobile myTouch 3G Car Charger
$3.12, free shipping. Mine came yesterday, plugged it in, and finally my GN showed charging as "AC".
Hope this helps!

When your smartphone shows your charger as ''USB'' this means that the USB data lines in the charger are not short-circuited. Then smartphone reduces its charging current to avoind any problems with USB laptop power sources
I made some experiments to check this point : see http://78michel.unblog.fr/?p=184.
I also opened a car charger and short-circuited the data lines on USB the plug . That way I have solved my previuos charging problem in my car during long trip.

this is what i bought: http://www.amazon.com/gp/product/B000S5Q9CA/ref=oh_o03_s00_i00_details
i've used it now 4 times, twice on a trip from south florida to orlando.
It charges the phone just as fast, if not faster than my home charger. On the way back, my phone was at 35%, within 2 hours it was back up to 100%. No GPS and a couple phone calls.
on the way up, GPS on and it never dropped below 97%.
so i can tell you without any doubt what-so-ever that this charger works perfectly with the galaxy nexus and will charge it with Navigation and phone calls running.

I bought a charger very similar to this one and it works great in my car. I make sure any charger I get is rated 5V DC at 1000mAh at least.

I have 2 USB 2.5A dongle chargers, one by Belkin and the other by Kingston. Both register as charging via "USB mode" and do not provide sufficient power while the phone is in use(loses charge usually). I also have that Motorola Rapid charger but the way the cable is designed it tugs on the USB port and comes loose often. I ended up just using the normal USB cable that comes with the phone and a 140W power inverter. Granted, it's not the most compact of devices, but it works well. I got it from Walmart for $20. Here's a link to it:
http://www.walmart.com/ip/Schumacher-XI14-Power-Inverter/15140199?findingMethod=rr
(and yes, using a power inverter will have the phone registering as "charging AC" and give a full proper charge.)

I'm using a Scoshe (sp?) dual USB port charger I picked up from Staples. It has a 1amp port and a 2.1amp port and I just use the micro usb cable the GNex came with

There was another thread, I think in the General that discussed all of this, what people came up with was the best combination if you want a dual port usb charger is to make sure you have a "charging only" USB cable. This cable will not make your phone think it is connected to a computer. You can tweek a data/charging cable to work but some people messed that up so it is probably worth just spending the $4 on a cable that works.
Here is my combination that works great. With this set up I can have on my navigation going with the screen on the whole time and stream Pandora over Bluetooth into my car and the battery still charges really quickly.
Dual USB Port with a 1 amp port and a 2.1 amp port (2.1 amp port is for tablets or power hungry devices - like the phone while navigating). http://www.amazon.com/gp/product/B0056VNVV8/ref=oh_o01_s00_i01_details
Charging Only USB cable:

This combo has me as "Charging AC" whenever I am in the car and I still have a port open to charge another one of the 27 or so different electronic devices that seem to clutter my life!

Thanks for this. It's been driving me mad how car chargers and cables are so inconsistent. Pun intended.
Seriously, why can they come up with a standard and call it a day?
I have a had a few GPS/Pandora runs. Even while it says AC charging and my charger is rated for 1A, it drains the battery by 300-400ma.

car charger?

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.
