Yes, but it does so very, VERY slowly and there is no indication on the tablet that it's charging.
Definitely an overnight kind of thing.

Is it enough power from USB port to use for example in-car navigation, at least for 10 hours?
Using car charger shouldn't be a problem at all. The issue is charging via the USB port on your computer which puts out like maybe .5 watts. They make a car charger with the proper end to plug into the charging port.

I brought a USB cable that fits into the power socket on the media pad on ebay. Cable works like a charm and charges similar to using the charger that comes with the media pad.
The charger was less than $10 including worldwide shipping.

Pls give the link to this USB cable. TQ
You will find a lot of them, if you type "mediapad power cable" on ebay search
I also got one of those USB to power cables. Result is 86% to 100% in 54 minutes from laptop USB.
The unit does charge from USB, but that's an overnight thing.

I did the same, only paid half that for a US seller and actually got to me next day.
eBay Listing
I think he bought cable + charger. If it charges as fast as the included charger, then it must be a 2amps charger, and that is a bit more expensive than your average cellphone charger (usually between 0.5amps to 1amps).
If he indeed bought the cable only, then $10 is a bit too expensive. Even at $4 is still too expensive. Probably not enough competition to drive the price down.

is there any way to tell if its charging via usb ...mine has stopped charging with the power supply ..... both power supply and pad being exchanged later today by orange uk ...but it would be handy to know for future reference
cant find a setting for charge via usb like i can on my phone or is it rom specific?
usb charging
With CyanogenMod 10 my springboard charged quite happily via USB. from a regular 500ma USB port it would charge very slowly while in use and only slightly faster with the screen off. On a 2 amp USB charger from my Asus tablet or 2 amp cigarrete lighter -> USB adapter it would charge fairly quickly either way
Then I updated to cm10.1 20130515 and USB charging quit working at all
I performed clear & reset from both the settings menu and TWRP, rolled back to 20130501 but USB charging is still kaput!
HELP???

Can i charge the media 7 tab before charge goes down (before the orange marking) or (before 5 percentage.)
I have my Huawei MediaPad T1 10 as dashboard with screen on 24/7 and 2.3A USB charger always connected...never reaches 100%
I have noted that the original cable works better.
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:

$10 -- PowerGen Dual USB 2A Heavy Duty Ouput Car Charger for Apple iPad 2, iPhone 4 4s 3Gs 3G, iPod Touch (USB Cable not included) --- Review
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.

My rocket fish model must put out more than yours. My pic is above your post. With Google Nav, Google play music (streaming, not native music), full sync, brightness to at least 50% it only lost 4% over 30-40mins.

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.

Hi! I'm having issues with my S3 charging via USB using mains. I tried 3rd party cable & original cable, both doesn't seem to work. The screen says its charging but after 30 mins, when went to check, the percentage remains the same. It was only when i switch off the phone that i managed to charge it. Any solution to this?

hmm. tried 2 different 3rd party USB power plug.
My experience so far: with standard charger + cable, this thing charges really slowly! An impatient person might even get the impression it's not charging at all. In fact if I use my S3 while connected to the wall (charging!), the battery will actually discharge instead of charge. Bottom line: plug it in over night, and consider buying extra batteries.

Mine charge pretty quickly (standard charger + USB cable)
But it does charge slowly if i use USB cable to my PC or laptop
Charging from a PC USB port not designed for charging will be slow as you aren't really getting all the juice you need. Best thing is to charge from the mains. My charger's fuse went the day I got my phone. As luck would have it, my Xperia X10 charger works just fine. So I now use that instead.
I experience almost impossible charging via anyone usb on my PC. I get info from device manager that the running port to my S3 outputs only 96mA, which is quite insufficient for charging. This is the first one smartphone which cannot be charged via USB port. I've had Galaxy Note, Galaxy SII, HTC Desire HD, HD2, etc... everyone is charging quite well from the usb ports... It's annoying...
S3 USB Charging Problem
I still haven't seen an answer here about the issue with S3 Charging via USB.
Mine is charging VERY slowly and it's infuriating. My HTC Desire S charges Via USB fine.
How can I find an official answer/fix from Samsung?
Charging problem should be related to kernel problem. I also encounter this issue before, but after i flashed Persues kernel then the problem fixed.

Sounds plausible. So how do I do that?
Was looking on Amazon for a micro usb adapter for my p5113 and could only find standard usb adapters. I want a micro adapter so I don't have to carry a separate cord around to charge this tablet and just use the same cord my phone uses. What was Samsung thinking going the Apple route with a unique plug?
