alternativ chargers?

last week i were on a holyday where i really didn?t have access to any form of power (that is unless i went into a store to use their power to charge my xda2 where i then had to wait for something which felt like a year for it to get some power)
needless to say that i didn?t use my xda2 all that much for that week
I remember that you for normal cell phones can get different types of funny chargers
Like one where you have to turn some handle to produce power
And also one which used solar power
Have anybody had any experience with such types of chargers and the xda series ?
I mean sure they would prob not have the right connector but modding one yourself using the connector from the charger to connect a modded wire would be a walk in the park

Hi Rudegar,
have a look at

Proporta iSun
I was thinking on buying the Proporta iSun...
That would solve the problem Rudegar had!
And of course it was a right good suggestion from bejay!
So anybody has it?
When you buy it does it comes with the right Himalaya cable?
Tnx.

Any charger that supplies 5V on a "sony walkman style" jack plug (+ on tip if I recall) will do.
Most chargers come with a variety of jack plugs.
The jack plug goes on the charger-to-mda-plug converter that was shipped with your device.
Worked for me in the car when I had no carkit

I just purchased a Covertec travel usb charger + car usb charger + usb cable for $19.95 + shipping from Mobileplanet.com Search covertec xda on the site. The DC 5V output is rated at 850mA or 1A. There is a review up on pccw.net.
I like the usb solution better because I can reuse the charger for most new cell phones, blackberries, pda etc. So I only need to carry one power source instead of 2 or 3.
There is another USB high current charger wiith a brand called Ecovell which costs $15 just for the AC charger.

For my it's a little bit expensive...
But who has core can buy it!
I'll remain on Proporta iSun solution.

http://www.coolpromotions.co.uk/rotarycharger.htm
i would asume this one is even cheaper not sure how many volts it give however and if using it could damage ones xda
also since it give somewhat less then 1 to 1 charging to 100% would likely take a great deal of time but hey they say we should get some workout once in awhile

good stuf for a reasonable price: www.time168.com
(also on eBay, but cheaper when bought directly)

Findings on Galaxy S4 charging current

With the advent of the S4, and its higher capacity battery, one could understand a higher charging current. However, I seem to have uncovered some findings that the charging system on the S4 is a bit more complex than first thought!
This is a bit techy, and assumes you have a basic amount of electrical knowledge, ie voltages, currents, resistance etc., but I'll try and keep it as simple as possible for anyone who may not!
To explain: The mains charger supplied with the S4 is a model number ETA-U90UWE, rated 5V @ 2A. However, the phone will ONLY charge at full current (which as I have measured so far, depending on what the phone regulates it to, typically sits in the region of 1.2 - 1.5A), when using the supplied charger (or possibly one of equal or higher current rating, depending on how it's configured internally), AND the supplied usb cable, OR any other usb cable, provided its shielding (the metal outer surface of the connectors) is connected at BOTH ends of the cable. Use a cable that doesn't have this shielding, and the charge current drops, regardless of whether there is plenty of current available or not. Use a different charger with an unshielded cable and the current drops even more, again regardless of whether it can supply plenty more current.
My assumption on this, is possibly an effort by Samsung to avoid the scenario of sticking 1.5 amps down a flimsy cheapo cable, the wires of which will likely be too thin to carry it.
After doing some probing around with a meter, I have managed to find a slight difference with the charger itself, compared to a generic one. In a generic one, the two data pins are usually just shorted together, which tells most phones that it's a mains charger rather than a USB port. On the Samsung one on the other hand, the pins appear to be shorted together, and also connected via resistors across the supply line (known as a potential divider), which holds these shorted data pins at a certain voltage. This is what tells the phone what sort of charger it's connected to.
Attached are a couple of diagrams to show the difference between the two chargers. There are in fact various setups of resistors that different manufacturers use to set the charging current, so it's quite easy to run into compatibility issues!
To make this a little less confusing I have done some preliminary experimenting, and I set out my results here.
For the test, I used combinations of 4 different usb style mains chargers: an apple iPhone one rated at 1A, an iPad one rated 2.4A, an HTC 1A one, and the genuine S4 one. With these I used two cables - the supplied Samsung S4 one (which is shielded), and a cheap generic one (which isn't). I started by measured the charging current directly with a meter, by using a very short usb breakout lead I've made, enabling me to interrupt the 5V line. However, I soon noticed that the use of any extension cables, even shielded, can lessen the chance of maintaining a good shielding connection, so I continued the exercise relying on the "galaxy charging current" app to get a reading.
Charger.................... Cable................ Current (A)
=====================================
HTC 1A.................Generic..................... 0.5
HTC 1A.................Samsung S4..............1.0
Apple 1A...............Generic......................0.5
Apple 1A...............Samsung S4..............1.0
Apple 2.4A............Generic......................0.6
Apple 2.4A............Samsung S4..............1.3
Samsung S4.........Generic...................... 0.8
Samsung S4.........Samsung S4...............1.3
So as you can see from these results, the original charger makes a difference, and the supplied cable (or a good quality shielded one) makes a further difference. If you have any further findings please feel free to add them here.
I can see that this is going to confuse some people, as it has me, as I'm sure some will inevitably try charging up their phone on generic chargers/leads at some point, with potentially long charging times resulting!
.

Very nice findings! Thanks for sharing them.
Not only what you say about longer charging time, but also discharging may occur (it has with me) while connected to the USB. I left my phone with USB tethering and it shut itself down after a couple of hours (it was low on battery already). I wanted to keep all the accessories in "new condition" in case I sell the phone in a few months, but I guess this justifies using the official charger and usb lead.
I hope someone can shed some light on the detection mechanism or the particular characteristics of the official cable so it can be replicated in generic ones.

From your findings, also Appe 2,4A charger has some control on the cable used, thanks.

Yes, but you won't be able to get more than about 0.75A out of it even with the samsung s4 cable.

You could try to add an extension cable to check if the charging system needs exclusively an original samsung cable from the charger to the phone.
Original samsung charger => extension cable male/female => original samsung cable => phone
PS: is there an app to check the charging current?

My experiments used an extension cable, that's the one I made into a breakout cable. So no it doesn't change by adding a cable.
There is an app, called galaxy charging current, which I tried also. In the 0.75A results above it showed a max permissible current of 1000mA, with the fully samsung setup it showed 1900mA. In the lower scenarios is showed up as 460mA. Other than that it doesn't tell you anything, it literally just shows you a max possible current, not the actual current it's drawing.

I've found out what the issue was, my generic cable was obviously a cheap one and wasn't shielded! I have edited my original post to re-explain.
Also I did a further test on a PC usb port - the Samsung cable allowed for 500mA, but the unshielded cheap one only allowed about 350mA, so (as pintycar found out), the phone actually carries on discharging in this case!

Interesting post.
I've been trying to mod a car charger so that the s4 draws more than 300mA so far unsucessful. I'm going to add in the 82K resistance and see what happens.

Hi,
Using a 5a digital bench power supply, I took a normal micro USB cable, cut it in two, added in the 82k resistors and tested.
Before: 450ma, after 1.73a
Then using a clamp meter I tested it with a 2amp Asus tablet charger - it varied between 1.48 and 1.61 amp.
I have since built a few more cables - one to use in my car (again 2 amp charger).
All in all, it works very effectively. Thanks for the initial research (saved me having to open my charger.)
BTW I suspect it is the charger where the resistors are, not the cable, otherwise the phone would try to pull 1.5a + from a laptop if you connected it.
Left my samsung cable at work so will test it tomorrow (if I remember)!

Interesting. So basically for us laymen, you are telling us to use the original charger and cables to the extent possible ... right?
Can you clarify to me what an unshielded cable is? Maybe with a picture? I've got a blackberry's cable at work connected to my PC.
At home, I also have a cable and charger that I got with my Nexus S (I think this says Output 5.0V ~ 0.7A).
Would this be a problem or can I get by with these?
Thanks

I've been using the Samsung cable+charger+USB extension cable and charging the S4 usually takes about 4 hours, I'm going to try with just the Samsung cable next time and see if it makes any difference since people are saying that theirs can be fully charged within less than 3 hours.

Hi,
I believe (guess work here ) that only the original charger "needs" a shielded cable - could be checked by shorting the ground and shield on one side and see if it works at the higher current - if I am bored I may do it - it probably checks the shield and limits the current if it is not there (note I have not tested this so only going by the first posters findings).
BTW a shielded cable has a wire mesh around the 4 internal cables - this mesh avoids external interference messing with the signals. Can't see it affecting the charging though BUT shielded cables tend to have thicker internal cables so could be related to this.
I have it charging at 1.7a on an unshielded cable (thought he power strands are thicker than average) Shielding should only affect the data transfer speed, not the charging current.
If the Nexus S has only a 700mah charger then this will not be able to provide enough current for high speed charging and could easily burn out - nice smell, dead charger, not much else. therefore only use a normal unmodified usb cable (and it will charge at about 450mah).
W.

all this would eexplian why the charger that camewith my S2 dosen't appear to charge my phone fully over night...

For what it's worth I'm charging with a Note 1 charger...a thick shielded cable via the S3 docking station....and getting 900mah...
will get my original cable tonight and have a go tomorrow...

interesting read, my s4 lead and charger are still in the box and I'm using my nexus 10 ones phone charged from about 30% to full in just over 2. may have to change the old HTC £2 lead I've got connected to my works pc then, maybe why it's struggling to charge when playing music. guess this is one way to get people to buy more expensive cables

Very interesting read, thanks TS.
My original charger and cable set is still in the box; I've been using my Mom's old Galaxy Note charger.
I'll try the original cable + wall mount and see how fast it is compared to my current charger.

After this thread I have stopped using my blackberry bold cable to charge s4 and of course the cheap one too.. thanks op!

I'm not sure if shielded vs. unshielded is the difference - probably wire gauge is the difference.
For example, if you shop at Monoprice, you have two options for USB cables: 28 gauge cables, and 24/28 gauge cables.
For wire gauge, lower is larger - the 24/28 gauge cables have thicker wires for the + and GND lines. A pure 28 gauge cable is likely to drop voltage a bit at high currents, and my observations have been that most newer devices, ESPECIALLY Qualcomm-based ones, are VERY finicky when it comes to input voltage drops.
As to the charger itself:
Apple chargers are almost guaranteed not to charge at full current, as they don't conform at all to the USB battery charging standard. Some newer Android devices do have at least partial detection of Apple chargers, so they may charge at 1A if an Apple charger is detected (any Apple charge, even 2.1A ones).
It sounds like the included official charger is a tablet-compatible one. Samsung tablets expect D+ and D- to be held by the charger at 1.2 or 1.8 volts (I forget which). As a result, Samsung tablets will not charge from standard chargers (like an N7 charger), but standard devices (like an N7) will charge from Samsung tablet chargers.
Now, the question is: Does the GS4 *require* a Samsung tablet-style charger, or did Samsung just include a tablet-style charger because it's backwards-compatible with standard devices? (less part numbers to track in inventory).
A useful pair of points would be: Using the same cable, does the Samsung charger behave significantly different from a Nexus 7 charger?

I missed this post on my first read-through: What happens if you just short D+ and D- when using the bench supply?

Cable and charger comparison: Samsung, Asus, Blackberry, Monoprice, Anker, PowerGen

I thought I would like to share with others my findings about the USB cable issues and the charging issues also reviewing few products.
I know that it would probably be best with some real table lab equipment but I have tested it with a usb multimeter device : PortaPow USB Power Monitor / Multimeter / DC Ammeter
Showing me Amps and volts.
It is true what is said that the device can detect to a degree the charger
http://forum.xda-developers.com/showthread.php?p=53917336
So I used combo of software and hardware testing. I also tested with a S3 and S4 rooted (custom roms), and nexus 7 2013 (unique to this charger that it specs the 5v at 5.2! @ 1.35A and it does push more, to other devise as well)
Not all cables are equal; even not all OEM will work past 1A. It seems that most OEM’s cheat by using a shorter micro USB cable to get better charging results, this is the question many ask why so short cables, the OEM’s are only now slowly moving to thicker power wires IE 28/24 in there OEM usb cables.
Now my findings about the PortaPow USB Power monitor and any of the kind, is that it seems to effect the charging Amps of the device and also effect any smart chargers (will talk about below)
In the past I used to use exclusively the “Battery Monitor Widget” by 3c, lately I went and got also “Galaxy Charging Current Lite” for whatever reason my S3 shows as incompatible? Thought it should work on it, my S4 installed and shows max and reference/average
Test 1: S3 Genuine 100% OEM cable (I know because I bought the S3 new @ t-mobile)
Test 2: Claimed Genuine Samsung Micro USB cable 5 feet ECC1DU6BBE
Test 3: Nexus 7 2013 usb cable (is claimed to be a 28/24 AWG)
I was skeptical about the Claimed Genuine cable, and though it looks and feels just like the real thing, it varies in the logo and length. Performance wise has shown consistently of a 0.1-0.15A lower than the Genuine Samsung cable that I have from S3. This was done with the USB power monitor and with the Galaxy Charging Current Lite app, it even said 860mAh vs 760mAh when I tested the cables, but genuine cable did push up more power and the software was wrong as I have seen over 1.13A with USB Power monitor, but as said the real Genuine cable was better.
The Nexus 7 2013 micro USB cable that is short, performed the best, gave the max Amps out of all the cables. I will test my Monoprice 28/24 cables and update this thread.
Quick tests of chargers:
Car charger form Amazon,
PowerGen White Dual USB 4.2A (20W) Car charger Designed for Apple and Android Devices
I quickly tested to see if this thing will push past 1A and it did at the time I was testing with nexus 7 and its cable with the usb power meter, and It was pulling around 1.13A
Next up single wall charger, I saw this and had to buy!
Blackberry Folding Blade Charger for Playbook rated at 5v @ 1.8A! priced under $5!!!
I tested this one with the software on my S4, it quickly showed after few min pulling 1.4A and Galaxy charger showed maxed out 1900 on all!
I think this one wins for the cheapest and sturdy charger, just shy of 2A!, will become my work charger, the cable is nice and thick along with pretty good length 6ft+!
Next up I had to get me a family charger (4-5 port)
I get tired of short cables on wall chargers, so I went and got
Anker® 40W USB Desktop Charger
This charger claims a total of 40w for 5 ports! With intelligent device detection PowerIQ.
This charger so far (1 day use) has been great, I connected the S3 and the power meter showed 1A, I connected the S4 with the meter and was only getting 1.13-1.3A, the software did not show max, so here is the issue seems the usb monitor will cause the charger to not read the devices to there 100%, after taking it out and connecting it directly the galaxy charger showed maxed 1900mAh
The USB cable used was the nexus 7 one.
What I love about this charger, no lights! Perfect for me for overnight charging, also has standard power cord, the unit itself is quite compact too, now I can have short usb cables 1.5ft or 3ft ones and not worry about reach, as the charger can stay next to your devices, simply use conventional power cable extender on the charger unit, not on your usb devices!
I will conclude that it seems now since we are pushing past the usb spec for charging, that the shortest cable is best, be it 28 awg or 24 awg, and of course OEM’s already knew that, I am pretty sure that the OEMs are switching to 28/24 awg cables

if people are interested, I can designate some time and take few pics of the monoprice cables, and show why they fail, its obvious but need a good pic to show the reason, maybe we can find a way to fix them?
the cables are great, the connectors look great at first but are not so great

I just ordered the Anker 40W USB Desktop Charger on Amazon with same day shipping for $5.99. Thanks for your review!

been using the Blackberry Folding Blade Charger for awhile now. indeed the closet and fastest ul get to the original charger
it can be had on ebay 2 for 4.99

the USB cable is as important as the plug. I use an ANKER 4-port plug with a factory S4 cable. It runs at 1900, same as if I used the factory S4 plug. I ran a whole experiment too. I had a USB cable IDENTICAL to my S$ cable, and it only charged at 320 with the same ANKER or S4 plugs. My S4 has a popup telling me to use a better charger

[Q] Charger

My moto g (1st gen) is about to arrive but I don't know how to charge it yet. I heard it takes long to charge in PC and I need a wall adapter for charging on the go anyways. Original brand ones are really expensive and I want to avoid that cost if possible. So is it safe to use a generic (most likely without any brand) wall adapter? For example one that says 100-240VAC, 50-60 Hz Output 5.0VDC 1.2mah. If not, what should I take into account when looking for a charger?
Thanks in advance.

It's not necessary to use original moto charger but it's recommended you can use any other chargers for charging With appropriate Voltage values...
Sent from my XT1033

All USB chargers have a regulated output voltage of 5 volts DC, and all of them are compatible with any device that charges via a USB/mini/micro port.
The difference is the maximum charging current, which generally ranges from a low of 300 milliamps to a high of 2 amps. More current will fill up the battery faster, as long as the charging control circuit on the device will accept more power. Regular USB ports like the ones on your computer are specified to put out a maximum of 500 milliamps current, so most device charging circuits will detect when they are on a computer USB port and limit their current drain to 500 milliamps to avoid triggering a "port overload" shutdown on the computer.
Devices with big batteries (like tablets) will take a long time to charge with a low-capacity charger, so you generally want to use a higher-capacity 2 amp charger with those to cut the charging time. Phones are generally somewhere in the middle - they'll charge in a reasonable time with a 1 amp charger, but they might benefit from using a 2 amp charger. You can still charge them using a low-capacity charger or a computer USB port, but you may need to shut the device off while charging if it consumes more battery power in normal operation than the charger can pump into it. And it might take a very long time (like 24 hours) to charge a big battery from a small charger.

Yes I'm aware of all this. The thing is I purchased it from Amazon and it doesn't come with a charger. That's why I need to purchase one. I know it works without problems with samsung, htc, blackberry, etc chargers but I don't know if it works -without problems and risks- with a generic charger. By generic I mean those chinese cheap ones that "imitate" original ones. So are those safe? Thanks again.

There's generally no problem with an inexpensive generic charger, but cheap junk is cheap junk. If it costs $1.99, and the connections are poorly soldered, the components are under-specified, and the construction quality is generally shoddy, then sure it can easily break, overheat, or go up in smoke. It could even conceivably damage your connected device. Just use some common sense in evaluating when something is too cheap.

I just got a samsung charger which seems to be for the note 2.. My worry is that I'm not entirely sure if it's original (even though build quality seems good) or not because of many reasons: a) I just noticed the model on the box (eta0u10ebecstd) is different than what is printed on the charger (eta-u90ewe) , including amperage listed (0.7a on box, 2a on charger) even though the box had the security seal b) I google'd about the model in the charger and I only saw it with the european plug presentation, didn't see a single american plug of that model (and I have the american plug). c) there seems to be 2 "presentations" with different printings (what varies is the location of the certification logos mainly and 1 extra certification for each "model" the other one doesn't have)
So my question is simple: Let's suppose the charger is not original, can it damage my phone? Thanks again.

If it is not Genuine avoide using as much as you can.
Using a genuine Samsung with Motorola or any charger made by real maunfacturer (Nokia, Samsung, LG, HTC.... etc) with any other phone is ok
but a duplicate charger is always a risk, because you never know what has been compromised.

Alright, I'll get a genuine one asap. Any tips to differentiate between an oem or duplicate charger?

"Genuine" is not a word that applies to USB chargers. Perhaps you mean "same brand as my phone", or "recognized brand name". That's one way to be sure you're getting acceptable quality. But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying. There's nothing wrong with most generic USB chargers, and there's certainly no problem using a different brand-name USB charger with your phone.

"Genuine" is not a word that applies to USB chargers. Perhaps you mean "same brand as my phone", or "recognized brand name". That's one way to be sure you're getting acceptable quality. But you'll save some money if you just use common sense in evaluating the price and quality of what you're buying.

What I meant is fake copies of brand chargers. It's basically impossible to differentiate between a copy and an oem, isn't it?

There are ways to differentiate then, but you need to measure the output under load and see if there is noise and ripple with an oscilloscope, which is not in everyone's possibilities.
Best way to get a genuine charger for cheap is to buy it from a friend who has it from some old phone. Or just look for brands like Nokia, Sony, Hama, Belkin, Energizer etc in some trusted sellers like Amazon or big local hypermarket.

Ok so I found 3 chargers on Amazon that seem to have good reviews but I don't know much about brands so I hope you can help me to choose (can't post links). Which brand is more reputable in chargers? New trent, anker or powergen? Thanks

Powergen afaik are making high-power output chargers.You'd be fine with one of theirs, their quality is airtight and the prices are good.

Question [Resolved] P7P Charger Options

I need a wall charger for my Pixel 7 Pro. I also need some way to connect my P7P to my computer's USB-A female connector so I can transfer photos back and forth. I tried searching on the internet but after spending 1/2 an hour looking on the internet for something my mind just turns to mush.
I came up with the Google 30-watt charger and 3-foot cable for $35 and a 6-foot C-to-A cable for $17 but somehow that seems like 'way too much money. What can I buy at a more reasonable price that would fast-charge the P7P and connect to my computer?

I can go on Amazon and get both in less than a minute. cables are between 5.00-25.00. Don't know where you are looking. You only need a charger than can handle 30 watts, as the pixel 7 pro can only pull 23 watts max.
PS I personally only buy good rated cable(mostly Anker). They run from 15.00-25.00. Highly durable cables.

For data transfer search for
USB 3.0 a to c cable
On Amazon, but don't buy anything too long, 3ft is more than enough in most cases (for data)
For chargers basically any 45w PD chargers will do. Anker and so on. 30w will also work but I prefer to have some excess in case I want to charge something that does go faster (power banks, for example)
For charging cable... Most c to c cable will do fine, I've been using the discount best buy home brand cables and they're fine. A phone like pixel won't draw nearly enough current to make the cable thickness matters.

To be fair even an old 20W PD charger will do if you have one knocking around given the P7P peaks at 23W.
Personally i like the Anker Nano III (which is 30W) and the Anker 643 cable (because its really floppy). For data transfer i just use any old USB 3.0 (or higher) USB a to c that i have laying around.

I know you want to save money. Who doesn't? But the fact is that you get what you pay for! You DO NOT want the cheapest, or the most expensive, in virtually anything (except maybe a heart, or brain surgeon...then I would go with the best)! Otherwise stick with the middle and you will not go wrong as long as the specs fit the need.

I like my old Choetech 15W PD charger. Because it use 5V - 3A , so the heat reside more on the charger block instead of on the phone (phone heat up more when the charger use higher voltage like 9V for example) an it still fast enough to charge my pixel which only tops at 23-24 even when using faster charger.
