Battery Charger ?

Hi Here in Mexico dont have a UK plugs and of corse my phone charger dont fits o the outlet but i have a USB Charger I can plug the Data cable to carge but the only question i have is this specs
Samsung Original Travel Charger is output : 5V = 0.7a
My USB output : 5V = 0.5a
Please Help
I think the only diff is the charges Times is less amp takes more time to full the battery.

i use the uk charger here in the u.s. i believe they are set for multiple power inputs just get a cheap adapter to change the plug configuration. that is what i am using.

i posted the below in another charger thread but in case it serves here
not sure if a lot of folks are just unaware, but every phone i've had charged fine from a usb port off my computer
since i started tethering my phone to my laptop (browse the web from family couch) december 2009, i haven't used the wall charger
even if i'm not tethering, i've got a spare usb cable on the desktop, that when i sit down at the desk, the phone or whatever device, gets connected to - far more convenient and fewer items occupying space on the desk
plus, i've got that Tmo car charger that just has a usb port on it's end - so the same cable that i use to tether to the laptop (when in the car), if i'm using the phone in the dock for nav, runs down to the charger - the charger, with no cable hanging off it when not in use, let's me leave the charger in the socket 24/7 - no looking for it in the glove box and untangling it etc
that charger is simply converting the 14V car voltage to 5 V the USB port normally delivers
2 - 3.5 hours seems to take my 1150mah battery from low charge to full
for what it's worth

There is nothing wrong with that. 5V is all you need. As long as you don't supply too high a voltage, your batteries should be safe. Don't worry about the amperage (current). Lower current (0.5a vs 0.7a) just means that it takes longer to charge the batteries.
And for those who really must have a wall charger that charges the batteries directly, you can buy a universal USB charger (http://www.dealextreme.com/details.dx/sku.15264). It works great. It plugs into any USB charger or laptop USB port, and charges any battery rated 3.7V. You can find them on eBay for just a couple of dollars.

[Q] got a generic charger....it says-5v 500mah,original is 5v 1a(amper)is this ok?

it says- output :5v 500mah
the original says-output:5v 1a(amper i guess)
will this screw up the battery?

chances are no, considering it is half what htc recommends you charge it with, either it will charge it very slowly (half the current of the original) or the voltage wont provide enough to kick the phone into charging mode and nothing will happen (i.e. the charger "wont work")

Thanks for the help

It'll work, but as panyan said, it'll recharge much more inefficiently than with a 1 amp charger.

Actually... It will charge the phone exactly as charging via USB, as USB is limited to 0.5A.

Yep, it will charge your phone just fine @ USB charging speed, I have a similar charger.

And some of you forgot to mention that the phone will struggle when for example you will play games or use gps. Charge will be insufficient and instead charging it will slowly discharge while using it.

Well yes and no, in normal usage it will charge phone, but when you use your phone the way that you would drain the batty in two hours, then it will discharge.

Hey... Yeah if the charger is a car charger then it may not charge fast enough if using GPS software which can drain the battery fast. 1Amp reccomended for faster charging... other than that should charge fine but just slow like USB charging (which has a max of 500mA).
One question guys... I bought a car charger from ebay listed as for HTC phones. It looks like a cheap knock off product with a glowing blue HTC logo when used in the car. The device is rated at 2Amps. Now from what little I know about electronics I've been told that AC/DC Plug packs with more Amps are ok and the device just only uses what it needs. I'm not however familiar whith battery charing when you have a higher rated Amps charger... Would the battery on the phone just be greedy and "ask" for the full 2Amps? Would this then put strain or be dangerous by charging the phone too quickly?
Secondly while we are on the topic of electronics... I'm trying out a super cheap ebay battery supposedly rated at 1600mAH (I know these rating are usually fake). I've noticed the HTC battery is around 4.17V when fully charged. This battery charged up to 4.2V fully charged... Is that dangerous for the device?

2 amp is better, correct me if i am wrong. So the output is 5V and 2A, is that mean the power is 10W every hour ?

2 A charging current (if the phone takes in that much) will damage the battery in a long term use.

It is incredibly unlikely that the phone will discharge the battery faster than it charges unless you're doing something very wrong, e.g. Running a console emulator while downloading a large file over HSDPA with WiFi enabled (but not connected) and using GPS navigation with screen brightness at maximum!
Screen and background services take approx 150mAh, and I doubt radio will take much more than that combined. That puts drain 200mAh less than USB charging, 700mAh less than direct charging.
FYI: There's a spec for USB charging of mobile phones from supported USB ports which can pull up to 1500mA.

Hmm... not sure for Desire HD I haven't tested GPS with SatNav software using current widget... I do know that I'm pulling well over 200mA just with basic use at home with Wi-Fi on and GPS & Bluetooth off and I kill all backround apps. I do know that I've been in the car and seen TomTom app on my friend's jailbroken iPhone 3G (or 3Gs) and with the GPS on and not doing anything intensive... we were actually travelling down a long straight highway, the phone was chewing more battery than the car charger could charge, so he switched off GPS.
Ah also guys no need to worry about the 2Amp charger... It sh*t itself on the 3rd car use and no longer works at all. Junk! I also noticed on the 2nd car trip that opening Android SpareParts the charge is displayed as USB Charging not AC Charging so yeah I believe that the car charger was only a standard USB (max 500mA) power output and not 1Amp let alone 2Amps. Annoying how false advertising or labelling is part and parcel with cheap Chinese products.I was meaning to test the charger's output with Current Widget (which is what I'll do for my next car charger) but the charger crapped out and was useless before I got a chance.
One thing I did notice from looking at a log using Current Widget while charging my phone on the A/C charger in standby, the charge tapers off the power output the more the battery is charged. To get an accurate idea of if the car charger is going to be outputting 1Amp I'd be sure the phone battery is down to 40% (or in the 40s) then with all other stuff switched off I'd run a log on Current Widget and turn the screen off for a few minutes. You should have a reading of around +700 to +800mA if the car charger is rated at 1Amp.
Be wary of the cheap Asian knock of car chargers with the coil spring cord and the HTC logo that lights up blue.... Not worth the 3 or 4 bucks they sell on ebay for.

There's commonly those double USB cables for laptop hard drives so yeah I can see that if the USB ports are actually giving you the full rated maximum of 500mA you can get 1Amp output with this kind of cable but 1500mA?!? The only way I'd see possible for this is either you have a tripple USB cable connected to 3USB ports that are all outputting the full 500mA (and that's if a triple cable even exists or lets say you solder another one onto a double cable) or you have a USB AC/DC charger or some other USB port/hub you've rigged up which provides more than the USB standards of max 500mA per port. How else is this possible?!? Has the max power output of 500mA changed since USB 2.0 standards?

yeah there are usb 2.0 ports with more than 500mA power supply.
some companys give some extra juice to their (or often only one) usb ports.
for example: i've got an Dell Studio XPS 16 Notebook here. it has 3 usb ports, 2 with normal 500mA supply and one with 1A (for charging your phone, etc).

[Q] Which charger uses data pins to verify as official charger?

On the Samsung Galaxy Note 2 (basically all Samsung Galaxy device), their two data pins on the official charger are shorted to be verified as a official charger and enable fast charge. If I connect it to a no-branded usb 12v charger, it takes a very very very long time to finish charging (like 5 or more hours bevause it only want to recieve 350mA rather than the higher rate on the official charger). I remember I dont have any problem charging my HTC Desire HD with the Samsung charger. But if I use HTC charger on Note 2 it also needs hours and hours to charge.
My question is what brand/model uses the 2 data pins to verify (or know how to charge when they are shorted) so that damage will not occur. Anyone knows the answer?

Several things going on here. There is a difference between USB and AC charging mode. I have had to short two wires in my car adapter to get my Nexus 7 to start charging with AC mode. Don't assume that every charger is capable of charging at the same rate. If you have a 350 mA charger, it won't charge your device as fast as a 2A charger.

I didnt mean that every charger can charge at the same rate. I wanna modify a 2A charger but I'm scared that if I unexpectedly connect it to an incompatible phone and something bad will happen. If a no-branded charger (data pins are not shorted) is connected even it's on the wall plug, the device will set it as USB charging and lower the receiving voltage so the device will charge very slow or the battery percentage will be dropping even when charging while using. My HTC charger can charge the phone that it belongs (Desire HD) in 2+ hours but the Note 2 needs 5 hours (this means that the HTC charger has no shorted data pins). And the Desire HD wont get an error when using a charger with shorted data pins (Samsung charger). What I want to know is what phone cannot be used with a charger with shorted data pins in case someone (or myself) use my modified charger to charge a incompatible phone and let damage occur.

S5 car charger that actually charges?

Hi all,
I have a couple of micro usb car chargers and when I was using a Navigator app whilst driving somewhere my battery just died despite the charger being plugged in and showing as charging?
I bought another charger off ebay which is a usb car socket with a genuine Samsung micro usb cable. It shows as 1A output and I plugged my phone in to charge at 1% with google maps running, half an hour later it had only gone up to 2%?
What I did previously was plug the 3 pin mains charger into a 240V inverter plugged into the cigaretter lighter socket and that actually charged the phone. Any ideas why the car chargers won't charge it, does anyone know of a car charger that actually will charge the S5?

buy yourself 4.8A dual usb car charger (2.4A per port).

If your battery goes above the 42°C the Kernell stops charging; the consumption of the phone can be up to 700mAh, so with 1A the charge must increase in about 5% in half an hour. with a 2A charger the kernell will accept another 800mAh as much, so you can fully charge your phone in more than three hours, (whe in a fully use) but always with abattery temperature lower than 42°C

I personally use the Anker Qualcomm 2.0 car charger, no problems, I like how fast it charges even if I am heavily using it (unlike other chargers I have owned)

Excellent,thanks both. I got hold of a 2.1a charger which seems to be doing the job well at the moment. Interesting thing about the battery as I have felt it get very warm at times, not always when charging though.

I bought this [Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with 22AWG 3.9FT Micro USB Cable(White)

I can really recommend this one: Aukey® Kfz Ladegerät 4.8A Dual Port Autoladegerät mini Car Charger, 2.4A+2.4A（4.8A max）dual Ausgänge für iPhone, iPad, Tablets, Smartphone, Navi u.a. USB-Geräte (4.8A dual Port mini Schwarz)
(Can't post the URL because of anti-spam bull****. Just search for that strink on amazon.de)
It's powerfull enough to charge a S5 and a S5 mini for example.

I have a genuine at&t 2.1 AMP car charger for my SGS5 and I never had any problems with it. It also has an extra USB port so you can charge two devices at a time (the 2 amps split to 1 amp for each device).

Weird charging behavior - New cable

I just received an Aukey USB cable 2m in length from amazon after reading many positive reviews. For some reason when i plug in(Samsung Note 2 and Sony 1.5A adapter), the charging bolt comes for about 2seconds(measured 1900ma) and goes off. I keep it aside for about another 2~3mins, the charge bolt comes(for 2s) and goes off again - this goes on a loop. I tried connecting to another AC adapter(Sony 2A CP-AD2) with the Aukey cable, but experience the same issue. I tried connecting it with my brothers phone(being a Samsung Note 3), the charge bolt does show up(measuring 1800ma) but the charge level drained from 4% to 1% while using for about 5mins while plugged(like as though it wasn't plugged in).
Now comes the weirder part, i connect my Note2 with the same cable to my macbook, to my surprise the phone does charge(460ma) as well as data transfer too is possible. The charging is true this time because i didnt notice a drop in percentage. This has left me very confused on where the problem lies. Has this occurred to anyone?
ps. i have seen people on the comments say the cable works perfectly with an Aukey Charger. I dont suppose a sony charger would interfere with a third party cable

Hello,
We speak about the USB Typ C cables right? I also got the 5 cable bundle from Aukey at amazon (3x 1m, 1x 2m, 1x 0,3m). So far the cables work perfectly, I use one with an Nexus 5X charger, one with an HTC charger and one with a car charging adapter (all with the 1m cables). When I'm at home I can try to charge my phone with the 2m cable to check whether it shows the same behaviour as yours
Edit: checked also the 2m cable, phone charges normaly, did you get a bad cable?
