I've bought this X1 car windscreen holder & charger off ebay...
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200317246131
The holder itself is very good for the price, but I'm a bit nervous about using the charger as it's not genuine SE.
It is CE marked, but it says its output is 5.0V=2A, whereas the output of my SE wall charger is 5.0V=700mA.
Is it safe to use?
you should be good. its the voltage rating that is important and not the so much as the amps.
i wish i can give you the technical as to why right now but i just cant remember all the details. i think your phone can draw in or pull in its rated amps. if your phone charger that you bought is rated at 2 amps, your phone can only draw in its max rated amps (700ma) and your charge time will be lower than that of a charger rated at 5 volts, 500ma.
if you did have a charger that was rated at 5 volts, 500ma, then your phone can draw in only the max that the charger can put out and will tend to overwork the charger thats rated lower and have a longer charge time.
Thanks for your reply
So even though the charger can supply up to 2A, the phone will only take the 700mA it needs?
Just out of curiosity, can anyone with a genuine SE car charger tell me what output it supplies?
BUT, charging that fast isn't the best thing to do for your batterly lifetime. Slower charging == longer battery life.
Though, same goes for the normal wall socket charger from SE.
Legaspi is right, the phone will only pull as many amps as it needs and can take, no more.
Well, I'll only be using it occasionally when I'm at a few car shows over summer. So it should be safe enough.
Cheers guys
amps are not pushed but drawn
amps is the max the charger can provide
before it get pressured and lover the volts
you could use a 5volt 10000MegaAmp charger
and the device would only draw the amps the device
was made to draw all the rest of the amps would stay
at your electricity company
ohms law state Amps == volts / residence

In other English:
P = VI, where
P = Power of device (watts) and is fixed
V = Voltage used by device (volts) and is fixed
I = Current (amps) and is decided by P/V (a fixed ratio)
So the device cannot draw more current than the fixed ratio. It may draw less current if the charger cannot supply the highest amount, but then as in one of the above posts, it simply takes longer to recharge.
With these devices, milliWatts/miliAmps are the scale, 5V is generally the fixed Potential Difference.
Used in a vehicle, the device is generally both drawing and expending energy (ie. charging and running say, GPS) simultaneously. This in/out situation when prolonged is the cause of the observed overheating with the original X1 battery.
i use a HTC car charger with my SEX1, it works flawlessly
I handmade two 12->5V converters (first with LM7805, second - with LM2678 regulator).
Both are OK, but I'm thinking about two stage regulation with radiators (LM7809/7805) or 5W DC2DC converter now...
Cheap car $5 5V USB converters usually use LM7805 without any radiators. So 500mA+ are hardly achievable.
hello , i just bought an genuine htc car charger for my xperia with the following carac : 5V - 2A
so don't worry , it's normal to have a more powerfull charger because when you will use X1 like GPS, he will need more power than a simple charge
Hi guys,
first of all, thank you for the great forum, with lots of useful information and application for my xperia.
I would kindly ask someone with an original car charger (CLA-70) to post its specifications here (volts, amps output).
I have a car (usb) charger from a BT GPS device that has a 5V,1000 mA output and I am not sure if it will suit my xperia. I need the car charger for use of navigation software, which consumes a lot of battery power.
Thank you for any replay!
i believe it's safe to use. I have a handmade 12-to-5V converter with 3000mA possible output and for over two months have no problems with X1i.
But Xperia will not use all your 1000mA. About a half or so at maximum. No 15 minutes charge possible...
I have done in many times. It is safe.
Don't worry!
I use the Kensington 4-in-1 car charger for iPod.
http://us.kensington.com/html/11205.html
Ratings are 5V and 500mA. It manages to charge my iPod, my X1, and my Plantronics Voyager 510 Bluetooth headset. Same charger, three cables, one Case Logic pocket, and everything becomes under your control!

No, no, no! Voltage is not fixed.
This is a variable controlled by the source. If you connect a device to a 3V battery, it is different from when you connect it to a 12V battery, yes? Your flashlight or torch battery will not start your car. But your car battery can and will burn your torch bulb. Therefore, it is important to always connect a battery, or in this case a charger, of the specified voltage, otherwise you will fry your phone.
P=V * I.
The higher the voltage, the higher the power.
For example: Your American 110V TV will not work in Europe, where the voltage is 220V. It will fry!

Depends on many things. FOA it depends on the type of PSU used in your TV.
Same correct for car converters. Be aware that during average driving your supposed to be 12V are really above 13V. May be even 14.5V.
What I'd not recommend is to buy cheap chinese converters based on 7805 chip. You cannot make it small, the radiator must be a half the size of Xperia itself. No radiator means a sub-100mA current at best.
Better to use something based on LM2678 chip.

Of course there are sophisticated appliances that allow for different voltage sources. I, for example, buy household appliances that are "multi-national". Like many international students that go to school overseas and take TV's and Hi-Fi's back to their home countries after completing studies. These have power supplies that that can be set to 110v or 220v. Now with techonology advancement, some gadgets will auto detect and automatically switch transformers as needed. The regular TV designed for use in America at 110v will not work in Botswana.
But the principle still stands.
P = V * I.
The higher the voltage, the higher the power! So what when I open the control panel and measure the voltage on a dc power supply it shows 23v instead of the specified 24. No big deal. But if it shows 48v instead of 24, then we've got a problem. The car battery is actually 14.4v. That is not the point!
Do not use a higher voltage source than specified. That some appliances are designed to take fluctuations and slight variances goes without saying. But all within reason. So, if your camera says use a 3v battery, don't use a 9v battery because sms2000 said it "depends".
I have experience with micro amps and other electrical devices.. I have two chargers a generic 5V 1A and a Motorola 5V 550mA. I just bought a desktop charger. The input is 5.2 600 mA and the output is 4.2 250mA. I use to have a batter application for my xperia and it would read 3.9V on the battery. will my chargers work ok. I am thinking to use the 1A charger on the phone and the 550mA on the desktop charger.
I should have read this before but the other day i got from a street seller a car charger, having seen him selling both 1000 and 450 mamp chargers, i got that 450, becuase i knew my phone charger was 700 mamp, i only need it when i use the phone as gps, not always.... but i didn't try it yet ... thanks

I'm going on a looooong trip next week, and will be away from home for about two weeks... Most of the driving will be of about 6 hours between hotel stops or whatever, and unless I'll be sleepy, I'll surely abuse my Note, haha. Will reach a hotel where I'll stay for 10 days, but the rest of the time will be wasted on the road...
So... a car charger is needed .
What would you guys recommend? In terms of brand, first... because I know some manufacturers write 1A on them, when they give not even half...
I've seen MOMAX chargers that give 1A @ 5V x 2 (had two USB outs) at about 15 bucks, for example.
I've also seen an orange-branded charger at 5 EUR (but it was almost double in lenght than the MOMAX one), with an included microUSB cable, that outputs 2A or 2.1A @ 5V. Would THAT one be safe to use? Or any charger that outputs >1.5A, for example...?
Also, will the phone charge faster if using a charger that gives 2A? I know it won't draw 1900mA out of it, lol, but still...

Formhault, last week I have purchased for my Note a Samsung car holder with 1A charger from this shop in Bucharest: http://www.alliselectronics.ro/inca...-ecsk1e1-pentru-galaxy-note-incarcatoare-auto
Unfortunately I did not test it yet on the car on a long drive and with the Note running empty; also due to the small form of the microusb plug I cannot perform any electric measurement.
I can confirm that measuring other car chargers of 0.5A and 0.7A I have found out that the o/p voltage is dropping a lot during the charging process, thus explaining the resulting low current and long charging time.
At he same shop you also can find a stand alone Samsung car charger, also of 1A at http://www.alliselectronics.ro/incarcatoare/auto/incarcator-auto-samsung-ecau16c-accesorii-tablete

The output current capability of a charger has nothing to do with how much curent the phone will draw while charging (of course the maximum rating of the charger must not be exceeded), on the condition that the 5V output voltage is not going too high at the lowest current consumption (when the battery is almost full).
Good luck in finding the suitable charger for your needs!
Mobile Inverter is the solution.

Try a mobile inverter and use your prefered wall charger. in 400W range you can charger all your devices. Try here:

I use a chinese one here, one with two outlets and 2 usbs 1A each. It's big but it's the perfect solution. Otherwise i have a powerjolt from griffin ,5A for the phone during car navigation. http://www.amazon.com/Griffin-Powerjolt-Dual-Universal-Micro/dp/B0042B9U8Q It's really small and stealth.

Erm... the first one looks expensive. I don't need a holder. No-go.
The second one is expensive, too, but I think I'd rather pay that money for THAT instead of the Momax one. GOSH, they don't state the lenght of the cable. Any idea how long that is?

Yeah... I kind of noticed that. The Note draws even 1200mA at times, and I tried with the original charger and a HTC wall brick charger (both giving 1A @ 5V). So yeah... guess the phone can draw more than the charger can provide, if that makes sense, lol.
So you're saying that even a 700mA @ 5V charger can give 1A to the phone? Or I got it all wrong?

No, I did not say that, on the contrary.
Here are some measured values:
0.7A car charger:
Open circuit voltage (disconnected phone):5.34V
Voltage under charging: 4.52V
Charging current: 0.6A measured on a resistor load
0.5A car charger:
Open circuit voltage (disconnected phone):5.31V
Voltage under charging: 3.16V
Charging current: 0.42A measured on a resistor load
Both chargers are doing the job, but very, very slow (2 to 3 hours from empty to full battery charge) and IF not many services are running on the phone.
Hope that helps......

Battery Monitor Widget - set the logging to every 60 seconds.
I attached the .txt logs to this post. Each log was done during charging, with Wi-Fi, Data and GPS off. Alarms were set to go off sometime in the morning (7 AM or 8, whatever), it is visible in the logs.
Even 2 and 1.6 amps were drawn at some point .
I used two chargers, because I wanted to see whether the HTC one can charge faster... if it can give more than 1A more often. It seems not, so I won't spend 10 bucks on a HTC one; will stick to the provided Samsung charger.

It is said that charging at lower currents/voltages is healthier for the battery. But no thank you... I'll buy a car charger that gives 1A, lol. Still haven't decided which one I'll go for, but anyway...
Thank you
I've lost my HD2 charger. Of course, I could just buy a new one, but since I happen to have a spare Nokia charger lying around as well as a 5-pin microUSB plug (solder type) I might combine these to make it work with my HD2? The Nokia charger is a 5V, 800mA output wall charger with a 2mm jack (cable has 2 wires; + and -).
Do I just solder the +5V wire to pin 1 and GND wire to pin 5 on my microUSB plug? No need to short pin 2 and 3 (D+ and D- ), or anything like that??
Will this work??
Thanks
Yes it will work.
Bridge data pins then AC charge mode will be activated, otherwise you will be charging slowly at USB rate of 500mA max.

Great! I'll give it a try later today
Btw, since the original charger has an output amperage of 1000mA and the Nokia is only 800mA, charging with my new "bastard" charger will take approximately 1.25 times (=1000/800) longer, right??
Your new "bastard" charger will take about 20% longer but I suspect in reality it will be less than that especially if Nokia charger is original unit as they will deliver 800mA & a little bit more.
If you open up the charger & run the usb cable internally for connection you could also add a 2way switch in the casing to the bridging circuit of the +- data cables making it selectable & thus a very universal micro usb charger for a huge range of devices.

The bastard charger works like a charm :laugh:
I only have HTC's in my home (HD2 and DHD), so for me there's no need to do the mod you suggested. Besides, opening the casing of the charger is not straightforward since it is all welded/glued together.
Thanks, Mister B

Couldn't agree more! I really hate throwing away fully functional/useful stuff, and the satisfaction when you plug it in and everything works is absolutely priceless...
Greetings! I was wondering what is the maximum rated input current of the Xperia Z. There's no indication of it's rated input current anywhere on the phone. The supplied charger is rated at 1.5A and I was wondering if a higher amperage charger above 5V 1.5A (such as of those catered to tablets/ipad) would charge the battery at a faster rate before investing in one.
Anyone with any experience using a higher amperage charger on the Z could advice on any notable improvements in charging time as well.
Thanks!
Used a Nexus 7 charger rated at 2A and it charged fine with no detrimental effects. Charging time is about 1.5, hours from 10% to full.

While increasing the Amps will result into fast charging... the bad part is that it kills your battery life overall.
I've tried Sony charger rated output 1500mA
and Galaxy tab charger 2A
phone on, screen off
in 10 minutes charge, both added , just the same, 10% juice.
may try it longer next time.

Great findings! I guess it's safe to say that there is no notable reduction in charging times even with the provision of higher amperage chargers, and that the Xperia Z's power management IC can only take in 1500mA at max.

Charging at higher amperage would generate more heat and this increase in heat would degrade the battery cells at an increased rate, thus reducing the lifetime of the battery in the long run
Well unless you value your charging time (or loss of usable time) more than the cost of premature replacement of battery, then quick charging is for you. Personally, given a choice, I'd rather not charge at a higher current unless necessary, especially when time is the essence. (;

Erm I'm fairly sure that whatever amp you use the phone will only draw a set amount I used a 2500mah charger with my old phone for two years no difference in charging time nor degraded battery life or iverheating , just meant I had one charger for everything lol
That's correct, it's impossible to over-charge or charge too quickly a device by using a charger with a higher current rating than the original charger. Current flow is a RESULTING property of a particular voltage applied across a particular resistance. Applying too much voltage will usually be detrimental, but you cannot SUPPLY too much current. The device will draw as much as it needs unless it is limited by the charger's maximum current rating first.
I've been using an old Blackberry charger rated at much less than 1000mA. It might take a bit longer to charge, but I love the long, supple lead that comes with it.

Questions:
Can the USB cable transfer more than 500 mA? From reading USB page on Wiki, looks like it can do 1500 mA - 5000 mA when not transferring data so I should not worry about the cable?
What is the point of including a 1800 mA docking station + 1500 mA power plug? Does the station only charge at 1500 mA when connected with that plug or am I missing something?

The charging chip it self support higher current by default, but the manufacturer chooses the charger depending on different factors, design of the phone, capacity of the battery and also their stock chargers available... they will choose the best charger to match... in most cases it will be rated lower than what the charging chip is capable of...
the charging chip has it's limits also... using regular USB cables will only provides the standard current... I've used same amperage chargers as the orignal but with different cable and charging was slower... when I switched to the original cable charging was faster and had the same time as original charger ( same amperage )
When you use the original cable and higher current charger then you will have faster charging...
My Xperia arc came with socket charger rated at 950mA and a car charger rated at 1200mA... and the car charger is really faster but only when I use the original cable, when I used a longer cheap cable the charging was actually slower... even when I'm charging non-Sony devices ( like my Note 2 ) when I use original cable ( wether Samsung or Sony one ) charging is always faster... I don't know why it might be a way to protect the standard usb cable from over-current as the standard USB current is 500mA, so the charger will normally send the usual current unless the device requested higher current then it will negotiate with the charger to send higher current the original cables might have something like impedance between some pins so the phone will detect them as original then they will negotiate the charger to send higher current or the charger might actually use the other pins to send higher current but the phone will only use these pins when it detect the original cable... if not then it will not use these pins and will have regular 500mA charging... I've always faced this when dealing with other cables... now when I want longer cable I just use USB extension cable with the original cable and it will work !

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Prefect thanks!
Can now make some docks/charging clips using sugru and a usb cable
Not sure why the dock would be rated at 1800, unless they've fitted it with some circuitry, a simple micro usb to prongs would do.
I charge mine using the adapter that came with my note tablet which is 2a and also with the 2a output of an external battery pack.

Yes, they're right to write the 1.8A there.
because, not all microUSB survive to deliver more than an amps. They maybe melt. especially the cheap one that have very small and loose contact area.
the pogo pins too... Not so easy deliver 1.8A with pogo pins...
that's why intel processor, have 1000+ pins, but almost 300pins are for power supply only (GND and VCC). Although the chip is only 1.25volts, but the current sometimes about a hundred amps (Core 2 Extreme, Core i7)

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Wrong. If you connect a 2.1A supply, you'll see no difference.
Charging rate is set by the phone, as long as the power supply feeding it doesn't "brown out" under the load.
2.1A, 3.1A - doesn't matter, the phone will draw less (I'll need to drain my battery down a bit to determine how much less, it's often less than whatever the wall charger is rated.)
There is a possibility that when it sees voltage on the pogo pin connectors, it increases charge current to a different value than on AC via the USB port. The ext charger handling in the pm8921 driver is really convoluted and difficult to read.
I've managed to find some chargers (both car and wall) that will charge with 1800mA (according to Galaxy Charging Lite app).
I have not managed to find an aftermarket cable that will charge at more than 1amp. Anyone know of an aftermarket cable that actually is capable of 1800mA? I've tried nGear and monoprice, and while they are very well constructed cables, they will only charge at 1amp or less with the n7100
Thanks for the help in advance, but please only respond to this if you've actually tested the cable with with the Galaxy Charging app or a current meter of some sort. I'm not interested in cables that only work anecdotally.

I'm breaking your rules (gasp) but as far as I'm aware, it's not the cable that manages the charge, it's the power adapter that feeds the usb, right? I've used all sorts of random cables on my travels for work, but always sticking to my 2+ amp output charger, and they've always worked.

Find a very short cable and you'll see rates up to 2100 ma (as measure by battery monitor widget). I use the short usb cable that came with my jambox combined with the the phones stock charger. The charger gets so hot due to the high current that I worry if it might burn out. The cable is very short, like 6 inches. I use this one when i need a quick bump before going out.
At this low of voltage plus high current, the shielding on most cables is not enough to protect against the voltage fluctuations caused by the high magnetic field. The longer the cable the more shielding is needed. Additionally, the cable shielding gets less effective as the cable gets older due to general wear. My original usb cable can only due around 740 - 1250ma, where it used to do 1800ma when new nearly 2 years ago.
If you could find a cable where there the positive and negative wires are separated in parallel strands like traditional AC power cords, it would also help. I have a cheap charger with built in cord like this and it charges consistently fast.

Most USB cables will work with the charger, but some cables (usually longer or smaller gauge wires) will restrict the charge to a lower amperage. I still haven't quite figured out how the phone knows what cable is being used, because, realistically, in a simple DC circuit, the consequence of using a cable that is too small is heating up or burning out. A cable that is too small alone will not prevent too much amperage from going through itself. This is why they invented fuses. Somehow the phone detects the gauge/length of cable being used and restricts the amperage being pulled from the charger by changing its own resistance on the circuit.

I suspect you're right. The impedance of a cable is the only thing that would change over a period of time that would result in a cable that could once pull 2A to start pulling less than that. Still, it would be nice to have a list of chargers/cables that consistently pull 2A before dropping $15-$30 on one of them. There exists such a list on this forum, but it is filled with comments like "It's good enough for me", without any real data as to what performance they are getting. Hence my rules above.
The charge rate depends on your kernal not the cable. I use Agni and get over 2 amp charges from a USB cable I paid 12 cents shipped for on eBay.
I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Thank you! This is exactly the type of review I was looking for!
:laugh:
Check this out. http://voyager8.blogspot.com/2013/04/how-to-choose-good-usb-data-and.htmlI found it while looking for the 6ft cable I used to use until it shorted from heavy use (bending a lot) and I got a pack of 10 short flat wire style 3ft cables. My 6ft one has a ferrite end and printed on it: 28agw/1p and 26awg/2c. It could handle 2A just fine, but this requires any wall outlet adapter that can output that amperage. The oem outlet adapter that comes with the phone says 2.0A output, but you can fine any 'reliable' one that has 2.0A output.
if the original cable is not 1800mA, there must be a reason
Get one of these

anyone have this cable... or know if it is a 28AWG/1P + 24AWG/2C (i.e., 24AWG/2C for charging)

Hi
Hard to get something original for samsung nowadays
I have those monoprice cables but get different results every time I plug in (1698ma, 1300ma, 600ma, 460ma, etc...)

Which 2.1 amp charger are you using? I have one for my car, looking for one for home use. I also have the 9300mah ZeroLemon battery in my T-Mobile Note 2. Thanks!

I was using the 2A charger that came with my Nexus tablet. But I bought an additional one for work.
iXCC ® Dual USB 4.2 Amp (20 Watt) SMART High Capacity [High Power] ... http://www.amazon.com/dp/B00HPTU0OU/ref=cm_sw_r_udp_awd_PR7.tb01EM5CB
$11.99 thru PRIME.
Had this one for almost 3 months now and it works VERY well. I get a full 1900-2000mah charge rate on the Note2 and can charge my tablet at quick speeds simultaneously.

some fake cable limit current.
Got similar problems as the OP. I wanted to charge my phone in my car and using the phone as a navigation device without depleting the battery (which occured a few time).
Tried several usb cables, even did some mods like shorting the white and green data wire in the cabel at the phone side, but that all didn't help.
Then i came to Kopi who sells usb cables which can deliver a full current.

Bought a few for 6 dollar each and am now a happy camper.

We're sorry, but there are no items available in the Micro USB (Android) category lol on the web site

I just saw it. Why don't you email them and ask about availability? I had contact with Victor Leung ([email protected]).
