So my charger met with an untimely demise. I am unable to get my hands on a replacement one at the moment.
I am currently using my computer's USB port which as you will know doesn't give quite enough juice. I have seen a microusb charger with 5V and 2A. Will this do a job (and also not get rid of the message that i am drawing more juice than the battery is getting)?
I use the charger that came with my Evo 4g. It needs to sit overnight, but it charges to green.

No.
The reason for the strange shape USB lead HTC have is that it gives 9V and 1.7A - 5V isn't going to cut it, it will charge but ever so slowly and if you try to charge whilst using it you'll probably find it doesn't, it just discharges more slowly.
If I were to take an old wall wart I have here that is 9V and 2A and wire a standard micro USB cable to it, would that work to charge my flyer quickly? In other words is the strange connector necessary or just the 9V and 2A?

NO, because the fast charge requires the special connector on the HTC power cord , a micro-usb will not allow the Flyer to draw the high current.

If you're using the HTC-specific microUSB cable, the adaptor would have to provide the correct amount of power (9V and 1.7A). Most usb power adaptors do not provide the adequate amount. A little while back, I made the mistake of taking just my phone usb adaptor to charge everything on a trip out of the country for nearly two months. It worked great for everything except for my View. Even though I had the HTC-specific usb cable for the View, it was still like charging via a computer usb port. It would get the job done if I left it all day or all night, but it took forever to charge.
I really would try to track down an OEM charger. Even if you find a usb adaptor that puts out the right amount of power, it still might not provide the short amount of charging time that the OEM charger does. It should theoretically, but many users have had charging time woes when using anything but the OEM charger.

No it doesn't. A member of my site took the OEM charger, wired a 90 degree micro USB port to it, charges at full speed.

Volts and Amps - PowerFlask
From the posts on this subject it seems that the Powerflask 13000 mAh powerbank I bought today and which charges at 5.3 volt with a 1amp and 2.5 amp port won't properly charge my flyer?
Can I safely use the 2.5amp port or should I rather stick to the 1amp port.
Any advice would be much appreciated.
Thanks

Folks on here have mentioned that the device (and other tablet/smartphone devices) will only draw the amount of current (amps) it needs. So using a charger with a higher amp rating is not a concern (in theory).
But I think others have debated this, and even made claims of higher volt/amp rated chargers damaging their devices (however anecdotal).
In any case, from the responses on this thread, it appears that any charger that doesn't have HTC's proprietary connector that they used for the Flyer, will charge the tablet very slowly. I just plugged my Flyer into a microUSB charger the other day (just got back from a trip, and my stock charger was still packed), and it charged extremely slowly. It was slower than I remembered it being. It was plugged in for maybe 4 hours, and only increased the charge by 10 or 15%.
PowerFlask Volts and Amps
Thanks for the feedback, much appreciated.
I ran a quick test and connected the Flyer to the battery pack.
The flyer charged from 76% to 84% in 30 minutes . I realise that such a short charge isn't a proper test but it looks promising.
I used the 1amp port and will as you cautioned avoid the 2.5 amp port.

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....
I use the 2m cable that came with my kindle 3 and it works as well as the original one

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

Click to expand...
Click to collapse
Has anyone else used the PowerGen car charger with the Note? I have a handful of other ones that all claim to fast-charge devices, but apparently it only works with iPhones and iPads. But since the PowerGen unit is on the list, can I assume people have used it and confirmed it will give me a 1A charge rate on the Note? I need a charger that can keep up with the Note occasionally drawing 1.4 A or more (display 100% brightness, GPS, LTE, Bluetooth all active, running Navigation).
A quick search for "powergen" in this forum only brings up the above thread.
Works like a champ. My battery was charging at 1600mAh while streaming soundcloud and using navigation. Definitely does the job.
I am using my car charger for galaxy tab 10.1 (2.0 amp) and it is working much better than any of the 1 amp chargers I have tried, OEM, boxwave, etc...
I also use the GT 101. 110V charging brick, so when I travel, only one brick and two cables. My experience is that the 2 amp charger works really well and will charge the phone while using GPS full time, where the OEM charger and other 1 amp chargers either maintain charge, or slightly discharge.
Thanks for the confirmation! Of course, now I discover Amazon won't ship that to Canada, and amazon.ca does not carry it. :crying: I'd go see what TELUS has to offer, but I'm sure it will be A) expensive and B) not have dual USB ports, or perhaps not even a detachable cord.
If you do find one, also buy a charge-only usb cord.

Is that still needed if the charger itself correctly supports fast charging? The cord I use now is the one from my Touchpad. I get 1 A to the Note from the AC plug, and the Touchpad gets around 1.8 A. I do also have a charge-only cable (much thinner cord, only two wires), but it doesn't seem to make a difference.

The cord from the touchpad is probably wired correctly internally for fast charge. I bought a similar dual car charger and did not see a difference with the micro usb sync cable. I only saw a difference with a charge-only micro usb cable. The phone sees what pins are connected and determines if it is going to charge in usb charge mode(<=500ma) or AC charge mode(>=500ma).

So you use the Touchpad USB micro cable to charge your Note in the car? I thought the cable is too short? I am looking for a LONG USB micro cable that is shorted so it will give >500mA.
I am planning to buy the PowerGen but I need recommendation on the CORRECT USB cable that is long enough.

I don't think it is, because it also works as a normal USB data cable. If pins 2 and 3 are shorted (D+ and D-), then the cable become "charge only" and cannot be used for data.

Then it sounds like that car charger was an "iPad-compatible" one, i.e.: it does not have D+/D- shorted out to indicate to non-Apple devices that it is capable of more than 500 mA.

The cable is about a meter in length. I only need about half that to reach from the plug to the phone mount on the dash.

So then how does it charge fast then? If the cable isn't shorted? Motorola does the same thing. IIRC its a shorted setup to allow for fast charging. All of my USB cables come from Samsung, HP, and Motorola and I use them as data cables as well

You short the pins inside the AC adapter or car charger, rather than the cable. If I understand correctly, the danger of using a charge-only cable is if you plug it into an actual USB port that isn't designed to supply more than 500 mA. Your device could then try to pull down, say, 2000 mA and potentially damage the power supply on your laptop or desktop.

I'm using the Rocketfish 3.1A Model# RF-M657D with my Note. While using Google Nav, lowest brightness, keys backlight off, Sync off, HSPA+, the phone still loses charge (albeit, slowly). I'm assuming this is because the charger is not internally shorted between pins two and three as it is marketed as a iPad/iPhone charger. I'm using a Belkin Data/Charge cable so I know that is not shorted.
I have been doing some reading and last night, I purchased the "Satechi Smart Adapter Compatible with Samsung Galaxy S (I can't post links yet, google it.) so I will report back when I receive and pair it with the Rocketfish.
One thing I can't understand is how some of you have reported 1600mA from your car chargers. I am reading that without this adapter/cable mod, the Note will only run 460mA or so. With the adapter/cable mod, the Note's hardware maxes out at 960mA. Also, is their an app that allows me to see how much amperage the Note is receiving or are you guys pulling out the multimeter?

Where/how do you get this info? Asking because I'm curious to see how my car charger does. It has usb ports rated at 2A, and I think it's 2A shared instead of per port, but want to see how it actually does when plugged in.

From what I read, your charger is an .5 amp.
It's not like my phone dies or anything, but it'll lose like 5% an hour and I could be exaggerating. Are you using a charge-only cable or modded cable/charger at all? Like I said, I think this phone is only pulling down 460mA without said mod and I find 1600mA to be incorrect as I read the Note will only pull down 960mA max. We'll see what this adapter does for my charge times.

I just hooked up my new Plugable 7 port USB 3.0 switch and although the speed is fine I noticed that the N3 still only charges at a lowly 450mA. Knowing that it should be capable of more, up to 4A in total, I decided to try a trick I'd been using for my Galaxy Tablets. These tablets won't normally charge from a non Samsung charger but with an inline dongle they will.
So I put the inline dongle between the switch and the USB 3.0 cable and presto, 1800mA charging current to my N3. Of course there is no data connection at that point but it's one less samsung adapter I need to keep around.
You can find the dongles here.

maybe you but the OP stated a 7 Port which means most likely it needs a power source i.e wall charger.
1. Even with an available wall power source, a USB Hub next to your keyboard is more convenient than the wall socket charger behind the computer.
2. A $5 adapter is cheaper than the original AC transformer.
3. You might not have the AC adapter with you when you're away from home but closer to another computer
4. A coin sized adapter is much easier to pack than an AC adapter
I'll be honest, I find myself in NUMEROUS situations where I have plenty of spare USB(3) ports but no spare wall plugs. My office is a prime example of this, from a 2-gang wall socket, we have 2x 8-socket extensions and those are all full. Some of those have another 4-gang extension coming from them, again full (mostly bloody adapters, so power draw isn't actually that higher - and yes we know it's a safety risk).
My computer, on the other hand, has something like 12 USB ports, of which about 8 are in use. Makes sense to me.
As someone pointed out the 7 port USB switch does have an AC adapter that provides 4A total. It's not that I don't have AC outlets at my desk, I have 10, but they're hidden behind a 400lb desk and not the easiest to get to whereas the USB switch sits within arms reach and is always on and available.
I also have several AC outlets around the house that have integrated USB charge ports. Given the number of devices that charge from USB these days these are very convenient but won't charge a Galaxy Tablet at all without the adapter. If you travel you will also find these at a lot of airports now too, usually located on the pillars in the waiting area.
In my experience at least it's a lot easier to find a spare USB port than an AC outlet, and that's assuming you have your charger with you. The adapter plug just helps you extract more charging current from what's available.
so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

Cool, thanks man, I'm gonna do that.
Why blow data when you can just get a cheap 4$ cable from newegg with 22 awg power leads. I linked it in confirmed usb cable thread. You destroyed a cable and made it special, hence using a special one instead of standard. The base is pre shorted. You increased AWG technically. Get it? You made a charge only cable, when these are special and can be had cheap anywhere. Buy a nice 4$ standard one with the right power lead awg and you can use it for anything.
...or.. Crazy idea here. Get an Android charger?
Cutting up USB cables is a bad idea, especially shorting them out. The data pins are not supposed to be shorted, generally 200Ohms is expected.
They are suppose to be shorted with fast charge... the base normally does this on plug in on AC switch. A USB3 port also does this... all he did was make a charge only cable. With fast charge 2 though, you won't make it much past 1A this way, just like USB3. Why our stock cable has thick power lead AWG and the phone can reach 1.8A.

As I said, 200ohm, not shorted... Anyway.
unless the plugg that u connect the USB cable in i sent chortcircut it won't fast charge whatever cable u use. this is for making a charge cable to use with carcharger ore power packs. of u use a wallcharger it's 99% certain it is already chotend and u don't need this. but if u use the original cable (fastcharge) it won't fast charge in a power pack or car charger.
and I charge att same speed with this cable then original charger cable that came with the phone. measured 1.8a with this cable that's all my Powerpack can output. can probably go higher depending on how mutch the phone can use.
it's li-po so should be able to charge 0-100% in 20min but whill shorten battery life and don't think oer phones can handle it
I fast charge with 3 different cables. Again, it's the AWG. Facts don't lie. My power pack and car charger are pre shorted, so all good. If not pre shorted though, you are correct sir.
my wasn't that's why I made this. so no matter what cable used it won't fast charge. Som people also say u have to by a expensive cable with is bull####
if someone can provide a link with a preshortens cable... well then show it. unable to find any
It is legit. I did this with a car USB cable when I had my One X. It would only charge at USB rate (500ma) even though it was a 1A charger. Using navigation the battery would discharge faster than it charged. Tried various cables, and only got it to work by shorting the data pair. After that it charged AC at full 1A.

Several available on Amazon:

Not always. My car cigarette adapter is modded to short data pins. It fast charges all my other devices and even my tablets, but doesn't even charge my G2. It says its charging, no slow charging messages, but still depletes battery. Only way toncharge in my car is to use the second USB port that is unmodded, which slow charges. Annoying.
I still think there is a software bug limiting the charging speeds because you can get different speeds by plugging in the same cable mulitple times.

We aren't saying you are wrong, you are just doing something different. It's not about expensive, its about thickness for the combo usb cable. Just the awg. What your solution does is increase awg. They are called charge only cables (pre-post short). What people were searching for are COMBO cables. You are using/doing something different. Why titles are called "working USB" cables, not charge only. We already knew this. There is bugs. That was apparent in the voltage testing. Something in the kernel isn't playing right at all times. I have seen this on my car charger. With no change in conditions, I can sometimes charge 200mA's higher with a replug.

The included home charger for the G2 is rated at 1.8A -- use anything smaller, and you'll see the pop up warning on the phone that charging will be slow and that you should use the "official" charger.
My guess -- if you can find a car charger that actually will put out as much as the phone wants to draw (e.g., 1.8A), and THEN use your shorted data lines, you'll see fast charging of the G2 in your car.

The 3SIXT micro USB charger I have is rated to 1A not modded, just bog standard. When charging I checked the battery stats and it says AC charging. Now I don't know if it has the data pins pre-shorted, but it managed to boost my battery by 10% in under 20 minutes. The phone was idle, but that's not bad going for a 1A $10 charger.
seems like the moderators did a god job deleting som posts.
just want to say I'm a sorry for my bad manur/attitude/language.
keep the input comming
here is another thread about the topic on another device

so got tired of not finding a fast charge mod so I mod the cable.
took a realy thin cheap USB cable and cut it in two. on the phone side chortsircut the data cables (white and grean) then connected the vcc+ and ground- normal.
the only reason I cut it in two was to be able to tread a shrink tube on the cable.
now I get fast charge from car and power pack and. and it works perfect.
now stop saying u need a special or expensive cable.
u need a knife and shrink tube and a heat gun (a cigaret lighter works)
and no u can't use this cable for datacynk only charge

not true have tried 3 other chargers 1.2 1.0 and 0.8 all say fastcharge (ac) with my modes cable. as long as it's over 500ma and with a cable with data pins shortend the slow charge warning is removed an the phone thinks it's charging from ac
charging my phone now with a Powerpack with 1a output and it says fastcharge (ac)
if I use the original cable it goes to slowcharging 500ma iv meshurd befor I put on the shrinking tube for isolation
and a car charger can output in theory 5-20a depending on your fuse in the car
the charging current is controlled by kernels in so phone. my old sensation u culd mod with a fastcharge Kernel so it never limited to 500ma always use max.
Samsung even has the ability to do a full charge in 30min but disabled in Kernel.
lg - g2 uses lipo battery's and culd actually be charged in less then 20min but if we do that u have to replace the battery every 6month at the best.
and lipo are extremely sensitive to over charge and the cells have to be charged with precision balans not to explode or swell.
