I have a 800ma charger that seems to take forever to charge my phone. I also have a 1A charger that charges significantly quicker. I am trying to determine if the cheap 800ma charger I have is just a crappy charger or do 1A charger charge that much quicker?
OE charger is 1A, from what i've seen it charges the phone the fastest, i should check what my charger at work is b.c i find it charges way slower then the OE
1A is the most it will take or you can just plug it into your computer @ 500ma. So 800ma will work just fine
great to know thanks so much!
The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.

Damn, those are some nice looking prices.
Monoprice is outstanding for many items. Look at the HDMI cables and wall mounts for TV's. All very good quality. Been using them for years.

Yeah I have a bunch of HDMIs from them too. I wish they had the mini usb to micro though.
I bought 4 micro usb (3ft, gold contacts, ferrite beads) and the car USB charger. So cheap.

3529 charges at 500mAh, this is close to the charging rate from a USB port (480mAh), so it will charge....but slowly. $1.16
3523 charges at 1000mAH, thats almost the same as the provided wall adapter (980mAh). $1.28
Shop4Tech has a car charget for $2.95 shipped but dont mention the charging current. I'll post back when they reply to my email.
just ordered 2 micro USB cables 3 feet from them for 4 bux! i love monoprice

With it being only 20mAH over, could that hurt the battery at all?
Bought 2 micro USB cables , and a Micro HDMI cable for varying items.
Total cost with shipping from best buy was close to 65$.
Radio shack 54$
Monoprice with shipping.
9.70
Why on planet earth would anyone look elsewhere.

The wall charger that came with my N1 lists the output as 1A (1000 milliamps) so it's identical.

It shouldn't. The quoted current rating (it should actually be mA, not mAH, which is a unit of electric charge or battery capacity) is the max amount of current it's able to supply. If the device on the other end doesn't draw more than that, which our N1s shouldn't, then it's fine. If the N1s WERE to draw more current, the power supply would probably break before the phone.
There's nothing wrong with having a more capacious power supply, and in this case, the car charger would charge our phones faster than the wall charger the OP bought.
Monoprice offers a 1000ma wall charger here, I just went with the 500ma to be safe. I will be using it at work while streaming music so a slower charger is a non issue.
I love monoprice.com The micro USB cables I bought from there look very high quality, very thick, and even has ferrite cores.
Monoprice is my favorite store to buy anything cables. Also the fact that they have thier warehouse 30 mins away from me, means i can pick things up same day. But all it not perfect, thier 3.5mm male to male cables are terrible. At least they have been since the last time i bought 4...
Thanks for making this post... I just picked up two 3ft micro usb cables, car charger, wall charger, S video cable, and 3.5mm to RCA cable... including shipping it came out to under $15!
Thank you so much for this site. I never knew about it till now.
A note about chargers and mAh ratings. My source is the Battery University:
http://www.batteryuniversity.com/partone-12.htm
They recommend for small batteries like cell phone batteries to charge them at less than "1C" (for the Nexus One that would be less than 1.4Amps or 1400mAmps) so these chargers should all be fine.
They mention that charging at higher currents can cause the battery to get hotter. Heat shortens the eventual lifespan of a Lithium Ion battery so "bigger" is not necessarily "better" in terms of chargers. A lighter charge can be gentler on the battery than a beefy charger.
They also mention that higher currents do not shorten the charge cycle by much. At higher currents the battery electronics typically kick the charge cycle into the "topping charge" state earlier and since the topping charge is very slow, it takes longer to get to 100% charge. A lighter charger may take longer to reach the end of the initial regular charge cycle, but it will turn over into the topping charge state much closer to full. Thus, a stronger charger will get you to the topping charge state (i.e. mostly full) quicker, but take almost the same amount of time to get to the really 100% full state.
I typically use a Blackberry charger on my phones - they tend to charge at lower amperage and so induce less heat. I also charge them overnight so even if the charge was slower it wouldn't really matter because 6-8 hours is plenty for any charger to get these phones to 100%, but likely the lighter charging isn't really taking much longer anyway. If I desperately needed to get my phone charged up very quickly during the day then I would definitely use the stock charger or a charger that was stronger, but still under the 1.4Amp maximum recommended current - but if you charge overnight, try using a lower amperage charger for long term battery health...
Charge rate is controlled within the phone. A 1400mA wall charger is capable of supplying *up to* 1400mA. There's no danger with using a higher rated wall charger.

True, but this is neither here nor there with respect to the points in my post.
First, the chargers that people are finding in this thread are lower power than that anyway so they can't provide enough to hurt the battery - whether or not the phone has the protections you mention. Perhaps the phone does protect itself, but the question does not matter unless you are talking about chargers that supply more than 1400mA which they are not.
My other point was that a lower power charger can charge the phone with less overall heat and extend the battery life. The phone will protect itself from damage, but charging close to 1C - while safe - doesn't help the battery last the longest it can.
My Samsung Droid Charge charger has an OUTPUT of the same voltage and 700 MILI amps.
My Blackberry Bold charger OUTPUT has the same voltage but is 1 AMP output... or 1,000 MILI amps.
If I use the Blackberry charger in my new Samsung Droid Charge will that mess anything up in the Samsung? could it shorten the life of the battery?
Thanks!
sure can, including wall chargers and car chargers
well if the amperage doesn't match exactly couldn't that mess up the Droid Charge?
it should be fine...but you might confuse your phone into thinking that it is a cutting edge smartphone circa 2006
If the power output of the charger you want to use is rated at less than what the OEM one is, you would only damage the charger itself if it isn't made properly.
The phone will pull a specific charge from the charger, say 500mA as an example. If the charger is rated at 400mA and doesn't have wiring to prevent an over-draw, you will damage the charger, especially if you use it for extended periods of time. If the charger does have circuitry to prevent over-drawing power, you'll just charge the phone slower. If you use a charger rated at 1000mA and the phone pulls down 500mA, using a higher rated charger doesn't make the phone charge faster as it will still just pull the 500mA. You'd just be less likely to damage the charger using one rated for more than what the device will accept.

I had purchased a usb cable a couple of years ago on kijiji for my BB bold back then because I didnt have a charger for it. Then I got the S3 and one time I randomly used the BB cable connected to the S3 charger via USB, I noticed the phone charged WAYY faster than the normal S3 cable does. Now I got an S4, and it still charges a lot faster than the normal cable for it. In fact I'm charging both my S3 and S4 at the same time right now, the S3 with normal cable charged from 4% to 15% in the exact same amount of time my S4 charged from 48% to 72% with BB cable. Does this mean I'm damaging my charger that's connected to the BB cable?

If by charger you mean that little box that plugs into the wall, that is actually a power supply. It just converts 120VAC 20A to 5VDC and whatever current it specifies. Also the stock s4 uses qualcomm quick charge, which means that if you use the stock power supply with the s4, it will charge at up to twice normal speed, provided you have a compatible cable (which it seems the BB cable is).

I've noticed that charging with 500mah charger, charges the battery MUCH slower than a 1000mah (1amp) charger, which charges really fast. I'll need to time it, but I'm thinking the 1000mah charger charges the stock battery in less than 2 hours, where as the 500mah charger takes many hours, I usually let it charge overnight.
My question is, is there any performance gain to slow charging vs fast charging? ie: slow charging giving a deeper charge, vs fast charging?
any opinions?
i use a 2amp charger i had already that fully charges the O3D in around half an hour/45 mins. get the same runtime whether i use that or the stock charger.

Any chance of a link to this charger, I'd really like that sort of charging speed.

My guess would be anything that would charge an iPad... those require like 2.1amp, so that would be a 2amp usb charger.... I've seen 2.1amp home chargers, car chargers, etc... all because of the ipad I'm guessing.
Its not that simple. Any device that uses USB for charging can only pull 500ma, that's a universal agreement. To get around this each manufacturer uses a method of "informing" their device that it is connected to a charger that can supply more current (HTC shorts the data leads in the supplied charger I don't know what LG does). I have a 1amp car charger but it still only gives 500ma but the genuine LG charger gives an amp because the phone "knows" it can supply more.
I'm going to stick a test meter into my LG chargers over the holidays to see how the data leads are connected.

The charger i have is a noname brand. I bought it from walmart for 6 quid. It also came with a 2amp car charger and a micro usb cable.
Micro usb cables are not standardised like that. Ive never heard of such a thing at all. As far as i know most phones will "fast charge" if they dont detect a data connection and dump as much current as they can into the battery so you can pretty much present them with whatever current you like and the charge time will just get faster. There is probably a hardware limit to that somewhere in the charge circuit but i dont know what the limit is. 2amps is the highest power usb charger ive seen but its not exactly aomething i regularly keep an eye out for.

Slow charging is always better as this will allow the optimal number of battery cycles before the battery's capacity will start to degrade.
So if you only ever slow charge then your battery will have a longer life cycle.
Can we use this USB to fast charge our Note ?

It's a charger that will charge fast simply because of the high amperage. I believe, and trust me I could be wrong, the fast charging capability has to do with the plug's output. Your typical outlet plug is 5v, anywhere from 500mah - 2.x amp. The higher the amps, the faster the charge. If you look at the fast charging plug, you'll notice it's 5v 2.1amp OR 9 volt 1.67 amp. I believe the ability to fast charger comes from the higher voltage capability. So while the 2.4amp charge rate is good and will charge fast, it's not the fast charging like using the higher voltage Samsung plug.
So my friend borrowed me his charger from his phone, which is a galaxy edge. It said it was charging rapidly and omg it sure did. It was super fast. Does the N5 support any kind of fast charge? Will this break my battert?

Thx,

how many output amps was that charger?
I tried charger that came with Galaxy S6, which has output of 5V - 2A, and 9V - 1.7A when recognizes fast charging device. It charges my N5 from 15% to 100% in about one hour, but on lockscreen, it only says "Charging", and charges it really fast, without heating the phone, which then seems to be pretty much safe.
@tampitzel If the phone doesn't get hot to touch on the back while not used when charging (warm is ok), then it probably is safe to use.
If the screen starts to flicker, or doesn't respond well to touches (eg. while typing), that means that charger is giving too much voltage and that's bad for phone. But that mostly happens with cheap non-original chargers.
Cheers!

I will check, I didn't look to be honest, I was just baffled by fast charging
Nexus 5's OEM Charger (by LG) is rated at 1 amp - whereas the Blackberry OEM travel charger (folding plugs) is rated at 1.8 amp - been using it for a year - and, it fast charge the battery typically in 1 to 2 hours (even when it's down to 25% to 40% on heavy use for the day) with its extra long micro-usb cable. http://www.amazon.com/BlackBerry-Pr...1449956341&sr=8-6&keywords=blackberry+charger
No need for custom rom or other "tweaks" - for in-car use, a 2-amp mobile charger with a high quality micro-usb cable is the "key".
Good and beefy cable makes an improvement more than you would ever imagine!
The stock charger is rated for 1.2A not 1A.
The Nexus 5 doesn't have any kind of official fast charging. However it will allow up to a 1.8A charge rate. Plug in a 2.4A charger it won't go any higher than 1.8A. Its what the TI power circuitry is rated for.
I find it a bit strange that through coincidence that the Blackberry folding blade charger is the best (I would say perfect) charger for the N5. It was cheap and plentiful as well as high quality.
