Can Milestone charger be used for OB?

I'm about to use a Moto Milestone 1 charger for OB but I'm afraid that it may harm the phone. Both phones are listed with MicroUSB 2. Any tips?
thanks

Don't worry.. it will work Ok, but OB charger has 1000ma, if you use another charger that has let's say 500ma (like USB) it will take 3 hours to charge the phone instead of the regular 45 minutes!
I use a samsung cable directly from USB, the car USB port, a samsung 5530 charger, a LG optimus one charger, and they all worked, with various degrees of effectiveness!
The most useful one is the car's USB port that, even if it cannot keep up with the GPS (it charges slower than the battery drains), it can keep the phone running with 10% loss every hour with screen activated and GPS at the same time! The problem is that I hate radio and don't use CD's that much, and usually end up with the phone depleted before I reach the destination!

Thanks man! Ok I'll check that "ma" thing. BTW is it written on the battery or charger?

Both places; battery specify working and standby V and mA, charger specify the V and mA provider
So you can use almost every different charger if the specs are the same, but be aware of this: don't use a charger with less mA since it can burn the charger

Ma - miliamps.
How many milliamps in 1 watt/volt? The answer is 1000.
I assume you are converting between milliampere and watt/volt.
I never had a burnt charger by the way, that would be very strange considering that the phone is accepting 500ma from the start (that is the USB output on any PC), and I even saw chargers with a power of 2W (SUPER FAST CHARGERS). The Motorola chargers are 850 ma usually, so it should work quite good!

Indeed, it's very strange to have a burnt charger and we don't need to go into an electrical discussion but that happens because of 2 possible things, very high-peak of voltage or prolonged use of under-voltage

Thanks. Printed on my Moto charger is 850mA so I'll rather use it for my OB next time.
BTW, currently I'm using a replacement charger for my OB with a name "super charger" printed "4.5v - 9.5v 800ma"
It's charging at normal duration in fact I'm using it for days. The only problem is that my OB touchscreen freaks out if I use it while that charger is connected. It's obvious when I run the multitouch testing app because touch points run all over the place. Touchscreen goes back to normal if I disconnect the charger. I tested that "super charger" to my milestone and the same abnormal thing happens to the screen. What causes it?

Probably it's something to do with high voltage... I'd avoid using it if something like that happens to my phone..
Usually the USB style chargers are pretty standard... the speed with which they work are strongly related to the power (Amperes) they provide, the voltage "should" be pretty standard!

Battery experts say to try and use a charger that's rated half the power of the battery.
So for a 1500 mAh battery, a charger of 850 mAh should be a better option than a 1000 mAh one.
Yes, the 1000 mAh charger would charge the battery faster than the 850 mAh one but it will decrease the lifetime of the battery faster.

Just for be able to post new thread. Sorry.

Hello, I don't want to start a new thread so I'll ask here.
The charger that came with my OB seems to be damaged. It was working properly until last last night. My phone detects the charger but it won't charge. Got powermax turned on and it automatically turned off when I connected the charger, so I know my charger does have issues.
Tried banging the charger last night, connected it to phone and started charging, woke up to see that it stopped charging 2 hours ago. It didn't even fully charge my phone. Now I'm charging it with my pc via the USB cable. I noticed that the touch screen goes wild when I use it while connected with the USB.
Now, I'm planning to buy a Galaxy S2 charger. Is it safe to use? S2 and OB has almost the same battery capacity so I'm considering it. Any other suggestions? OB ain't popular here in the Philippines so finding accessories is a real pain in the a**.
Fitted a Corby 2 charger and it seems like they use Mini-usb too. Haven't tried charging with it though.

My original charger also died... Now I use the one that came with my bluetooth headset
So I guess using the OB charger on other stuff is okay too. USB is always ~5v.
You need to test the charger with something else to be sure, though.
I had the same touchscreen freaking out problem with my old LG KS20, whenever I charged it. Like it was shorted or something. So it maybe a problem with the phone itself.

So, you agree that I use a Galaxy S2 charger? I think it would be fine since my friend with an S2 used my charger to charge his phone and it went well. I'll ask him to buy me one tomorrow. Tnx for reply

Ok kabayan, don't forget to share here the result after u try gs2 charger. I too am looking for safe alternative to my milestone charger.

Standard port - standard voltage
Don't even bother, if it has a micro USB it should be fallowing the same standard as USB for charging (5V)...
Of course test the charger for any adverse side effects like screen flickering or short battery life, and don't use it if something like that occurs, but because of the standardized voltage and the fact that usually phone chargers have between 500 - 1000 mA, 99% of chargers work...
I still haven't found any incompatible charger for my phone and I don't even buy a phone if it has a non standard Charging/Data Port... it's just stupid... so no Iphone for me!

Hello guys! I'm here for an update. For the past week I've been using a Corby 2 charger. And guess what, it works just fine! only downside is it won't charge it up to 100% (usually gets to 99% upon unplugging). And it charges the phone a little slower than the original charger. I always let the phone overcharge overnight to have 100% battery.

Since somebody stole my laptop (and my charger too) I'm using a ZTE Blade charger without problems...

[Q] How long does your tab 8.9 charge?

How long does it take your Tab to charge from about 0-20% to 100%?
It takes mine forever - about 16 hours, although I'm on stock Honeycomb rom

I'm not completely sure, but 16 hours seems to be too much to me. I usually charge over night, so i guess it might be something around 8 hours.

I think so too!
I just wonder what is causing this... (1) some faulty chip in the tab itself, (2) faulty battery, (3) faulty Samsung cord or (4) faulty charger. No way to find out for sure, unless I return it to the shop and wait about 30 days (at best) while they figure that out and give their verdict
I hope someone has\had this problem and knows what exactly was causing it.

the last 5% take forever. That's usual behaviour for charging. Check out how long it takes to charge to 90% or maybe 95%. Should not take longer than 6 hours. If it does then maybe try a different charger or reset your tab to make sure it's no software bug.
Hard to tell the real source of error, sorry...

Are you ABSOLUTELY certain to be using the original, for your tab, charger, with a 2 amp output.
With such charger, it should be about 4 - 4.5 hours.
But if you are using a generic, or something made for an avg phone, with .5A output... Well 16h seems normal

Mine is about 6h

I am using Samsung banded charger that came with the Tab.
Sometimes it does charge fast, but most of the time it either charges very slow, as though it were charging from USB, or doesn't recognize the charger, or even says it's established MTP-connection...

from 8 to 10 hours on hc 3.2
but now on ICS take less

using the charger that came with the tab, you should get charging times around the 4/5 hours. HC 3.1 and 3.2.

Does the cable work properly when you use it for USB operations (file transfer, etc.)?
If so, then maybe the charger is broken/faulty. Samsung (in its infinite wisdom ) put a resistor network in their chargers so that the tab/phone can recognize a charger vs a usb connection ... or maybe just to make money from over-engineered accessories. who knows? However, if that resistor network has failed (or the cable is broken, hence the question above about USB operations) then the charger will present as a USB port rather than as a Samsung power source.
Oh! Another data point to consider: does gently wiggling/straightening the cable when it's connected cause the behavior to change?

There isn't much difference with ICS 4.0.4 US rom in my opinion. And it is still picky what chargers it accepts when it's turned on (DX.COM charger works for me). I usually turn the TAB off and use a stronger charger, but it still takes a LONG time to charge in my opinion. I do an overnight charge as much as I can.

Did an overnight charge with the Tab turned off, and it charged to 100%, finally. But when it's on (even in airplane mode) it only charged to 60% last night (took 12 hours!).
Weird)

i always charging my tab from 0 or 2-5% to 100% either when powered on or off and it always takes 5 to 5 1/2 hours. no more and no less with default charger set.
first i thought it was taking too long but when i saw this thread i'm glad its only 5 hours

Common belief (knowledge) is that this is not the best for a lithium ion battery... It increases the wear, gets it to lose capacity sooner... If possible, charge your battery often, like as soon as you can below 75%. Only occasionally drop battery to 0%. IIRC, there's a good website called "battery university" talking about that

Thanks, used your post to fix mine. I ended up replacing the cable and not the charger. I'm using an original charger with a new cable now.

I am seeing same problem with my brother's 7300 tab as well. Its taking around 10 or more hrs to charge.
Anybody got tablet replaced in warranty for the same reason? Even with Nexus 7 original 2 A charger its taking too much time. With samsung original charger also it was taking similar time so i am sure problem is with the tab only.

4-5 hours on mine.
Sent from my GT-P7310 using xda app-developers app

Many Galaxy tab 8.9 owners have reported experiencing long charge times to the tune of about 16 hours, me included.
Solution:
Plug in the charger to the tab very very slowly. The charge icon in the system tray has a lightning symbol on it aka normal charge.
Connecting it at normal speed results to the charging icon in the system tray having a cross on it. It then charges very very slowly.
Why should we need gymnastics to normally charge our tablets? Ask Samsung.

Charging Issues, special cable and charger needed

Just picked up this phone and I love it. On stock 4.1.2 I have charging issues where the phone will only charge with a very good charger capable of putting out >1A and a beefier cable.
Which rules out charging from computer and some shoddier chargers. This is a deal breaker for me.
I will go ahead with rooting and upgrading OS to custom, if someone can verify that this will be a non issue after completing that? Thanks.
Edit: further when streaming netflix and charging, the chargers can't keep up with about 30% screen brightness. Will also be resolved?

how many chargers don't output 1a or greater these days? im using a htc hd2 charger that's nearly 4 years old and a generic usb cable and have no issues charging the phone

Well for the second point I'm even using a 2A charger and and its charged 3% in 2 hours, with netflix, which seems more like a software issue.

and have you rebooted the phone? I had issues like that on my old galaxy note, a reboot often fixed it due to other processes and apps running in the background

I also am struggling to find a decent cable to charge my phone with.
The supplied cable charges it very quickly, but is a little too short to comfortably use the phone while it's charging.
I have purchased a couple of longer cables that seem to be of decent quality (24 awg), but the time to charge the phone fully increases dramatically when using them.
This is all when using the supplied charger.

Tried the reboot, still the same issue. I think I've realized the problem and it looks like software.
I have a kill-a-watt meter. With screen on, and netflix streaming, for some reason its only drawing 3.3W. @ 5V this is only .66A. Clearly too low to charge with. However when I turn the screen off, after a few seconds draw goes to 8.2W, ~1.6A. Now I'm not concerned with staying on the stock OS, however do people still have trouble with this on custom OS?

Sweird...I've never noticed any slow charging on my 6606. I've used a few old chargers from HTC , nexus and Samsung. My Motorola Bluetooth charger however doesn't charge very fast at all but I'd expect it not to.

Its not the best to use ur phone to much while charging tbh. It might kill u battery quickly and damage the phone itself.

Which charger to use? (no quickcharge)
I bought a Samsung charger for my upcoming Nexus 6, i don't want to use the quick charger that comes with the phone. I am starting to suspect that this one is also a quick charger, can anyone look at the attached pictures and tell me? Also if it isn't a quick charger i would like to use it for the long run so my second question is would my battery be affected because of what says on the back of the box that i highlighted? In the highlight are also the specs of the charger, can someone clear this up for me?
EDIT: I cannot post pictures on the forum just yet, so here are the specs
10W Samsung travel adapter, Input 100-240VAC 50-60Hz, Output 5.0VDC 2A
Use only with compatible Samsung devices

I want to use the phone for a couple of years and don't want to shorten the battery life and also have the risk of inflating battery and everything that comes with it. What kind of charger should i buy to charge it in some "normal" time? The salesman in Samsung store told me this one charges Note 4, Galaxy S5 - which is why i bought it - the S5 doesn't have the quickcharge tech so i instantly thought it was an ordinary charger. On the other hand, my Galaxy Nexus official charger is rated for 1.0 A which surely isn't strong enough to charge the 6 properly so i am confused with what kind of a charger and with what ratings should i get? Thank you in advance.

2amps isn't going to shorten the life below 2 years. Higher amps only shorten life if they are above battery tolerances, which 2 amps is not.
Anyway, you'll want a 1 or 1.2 amp charger for slow charging

If I were you, I would use the charger that comes with the Nexus 6. Which is tested by Motorola to work properly. I've had my Nexus 6 since December 2014 and no problems. I charge through my laptop will at work though.

He wants slow charging. So charging through laptop / pc will be fine.
Charge cspacity of usb ports is 500 mA (900 mA for USB 3.0), that's good for slow charging.
Also 1-dollar charger from eBay will be fine.

That said for me, turbo charge stopped working and I'm very annoyed.
Google have first sent me a new charger which still hasn't arrived. Though I think the issue is the phone. But I wanted to avoid a refurb as long as possible. Can't live without turbo charge now.

I have this charger, http://www.walmart.com/ip/Belkin-F8J031TT04-BLK-Micro-Wall-car-Chrg-Kit-2.1a-10w-W-4ft/40457559, but i got just the charger for $20. It most definitely doesnt turbo charge, it takes atleast 2 hours, so id say its a "normal" charge for this phone and i think its better than the turbo charger, because it doesnt get hot and its still decently fast

The turbo output is only supplied on turbo enabled devices. So there is something wrong with switching to turbo modes 9 V and/or 12 V
I am curious what is the cause of this issue.
Did you try an 'charge app' like Ultra Fast Charger.?

There are some apps in the play store claiming to boost the battery charge.
When wireless charging is also slow, than it could be indeed the battery.
Maybe a complete discharging ?
BTW
Turbo mode is only active when the battery is less than 75% charged.

You should use a 5 Volt 2 Amp charger, those chargers are the one's that most phones use. Most new phones are using Qualcomm's Quick Charge 2.0, which you should use but if you are not comftorable then the 5 Volt 2 Amp will work good.

Errr, QuickCharge will in fact degrade a battery faster, it's still used because most phones only have a 2 year lifespan.
A non QuickCharger will also make it run less hot while charging and also be less likely to cause cell expansion. Not sure why there's so many people denying this.
EDIT:

Please don't tell him that it won't degrade his battery when it definitely will. It's basic chemistry.
To OP:
Any regular non Quick USB charger of reputable make will do fine. I use an older HTC charger. Don't get a super cheap offbrand one as it probably has fluctuating voltage which will also damage your battery.

Actually you've misread (or not read fully). No one disputes the science. That article isn't accurate. All it says is "too quickly" and if you read what I have said, is that the turbo charger is within acceptable tolerances. I.E. It is not "too quickly"

I think you're not understanding the basic chemistry. More heat = more degradation of the Li-ion battery, regardless of tolerances. A lower power charge will always degrade the battery slower. This isn't about tolerances.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V20 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

I use Ampere to see the rate I am getting. First plug in might only be 90 mah. I unplug, replug, it jumps up to 350. A couple more times and I end up at 900-1200. Screen off and let it fast charge.

I recently tried out the HTC Bolt for a couple weeks and it seemed to charge much faster than my V20. Shouldn't it be the other way around since the Bolt uses quick charging 2.0 while the V20 uses Quick charging 3.0?

Slowest charging phone i ever owned but i still love it lol

My H910 charges relatively quickly. Just plugged it into a quickcharge 2.0, not 3.0 car charger and it went from 16% to 50% in ~25 minutes.

I regularly get rates of 1.8A or greater using a CHOETECH or Anker charger. One its above 80%, it drops down, but this is normal.
The Anker is QC3.0 and the CHOETECH are QC2.0

what's with V20?
it uses QC 3.0, but charge slower.
I use original V20 charger, and when charging the status is "quick charging.."
it takes 2 hours from 27% to 100%
:sad

looks like something really wrong with your phone. My phone usually takes about 75 mins to charge from 0% to 100%

maybe, but it looks like not just me though.
and btw, my LG G2 can do full charge in 1 hour and 20 mins (80 minutes), and it's not even QC 3.0
I read somewhere in gsmarena, QC 3.0 should charge to 80% in 30 mins

not sure about G2. I've never had one.
QC 3.0 might be able to do it technically, but I've never seen a phone that fast in charging yet. Not even the OP3T which every body is saying quickest in charging.

Hmm.. okay.
How about your G Flex2? how long it would take to charge to 100%?
G Flex2's battery 3000mAh, right? Same as G2

That grandpa tooks around 2+ hrs to get full charge
But to be fair with the phone, I've never used the original charger of G Flex 2 to charge. I either used my old chargers from previous phones or I plugged it into my laptop to charge it. Let me find the original charger and try it when i get back home

Great
Very fast charge

Delete please.

I have absolutely no complaints with the charging speed. Also, I rarely drop below 40%.

My battery takes forever to charge up!
I just bought a VS995 Verizon Unlocked off the net. Was classified as "almost new - open box", hope I did NOT get a unit with problems. Re-charged it now a total of 5 times and on average (plus or minus 3-5 minutes) it takes approx. 3 hours and 18 minutes. for a full charge 0% to 100% . A few thoughts and questions came to mind while reading all your excellent posts:
1.) I believe he must of lost his quick charger because the one he gave me seems like he bought it off the net. Standard USB charger. So probably not using the quick charge function feature of this phone correct?
2.) Can I goto an electronics store and just copy whatever voltage and amps I need to perform a quick charge? Can someone please POST what the voltages and amps needed for a quick charge 3.0 please.
3.) Anyone have a bad battery or have one go bad after using the wrong charging devices? I was thinking of ordering a new battery BUT they are a little pricey. Anyone know some good outlets to buy them at a fair price?
4.) Does rooting the device and putting one of the ROM's on their cell solve anyone's battery problem? If so which ROM do you recommend?
Overall that is my only gripe about the phone. I love the DAC and for all you music lovers out there try Sirius XM on the LG-V20 and make sure to use Hi-Fi made headphones. I bought myself Bowers and Wilkens P7's, sort of pricey but worth it to me. The other thing is Napster as well the songs you download sound awesome with this DAC. For both of these APPS make sure you go into settings and adjust the quality of the downloads and streaming. Otherwise you could be listening to it with poor quality settings from the get go.
Ok well I appreciate any help or advice on my battery situation!
Thanks in advance to anyone helping me out.

Any charger that says Quick Charge 3.0 would work. I think even QC 2.0 would charge at the same speed, but just less energy efficient.

The difference between qc 2 and 3 is 3 has a variable voltage allowing it to use energy more efficiently.
Excess energy is lost as heat on qc2, the power is reduced in qc3 when the battery starts to get full.
The charge time is the same.
Specs for QC 2 is 5V / 9V/ 12V, specs for QC 3 is
3.2v - 20v dynamic
