Charging from USB?

I keep getting a red X Through my battery when plugged into my laptop to charge, is this normal? I really dont want to plug into the wall to charge

Really hope this doesn't become the case and that it will charge off of any USB charger...in particular like the one in my car that accepts USB Devices.

My friend has a galaxy and has the same issue, idk if its our laptops or what

Okay this has been address. please search but ill answer for you.
This device uses 5v 2a to charge. Hence the wall unit. you computer is 5v 1a or 1.5a (its not enough)
The device will maintain and in some cases when screen off slowly charge when plugged into computer or usb adaptor with the red "x" through it.
you can find a usb adapter cable which has a switch to allow you to charge while connected to a computer. its a data and charge switch. search for it. i think its on ebay.
also you can find on amazon or google shopping wall chargers for the p1000 which work for like 8$

my 4 didn't and neither does a bunch of other peoples xooms. even if it did it would only charge at the same rate as the gt10.1 charges - 5 watts. that's the max USB 2.0 spec.

It should be easily solved with a 2 x male 1 x female usb cable

Those double cables are cheap (around £3 in the UK) so I might pick up a couple of those and leave them at work and in the car

Having this Y-cable will also help with the fact that the USB cable that came with the tablet is so sort. I have a lot of 5V power supplies around but they are all from 50ma to 1a. Can't believe this thing needs to much power to charge, I would think that 1a would be enough just to maintain it when in use.

OK, I got a couple Y/Split cables and I still have red X when plugged into two USB ports, I even tried two ports that are on different controllers... as well as two USB3 ports in my laptop. I even tried my desktop. No luck.
Has anyone gotten this to work?

The red x will show up if you are charging with anything under 2A. If I remember correctly usb 1 puts out 100ma and usb 2 & 3 put out 500ma. Even with a Y adapter you will only get 1A. If the screen is off then you will charge the battery however with the screen on, you are using the same amount of power that the usb is providing. Therefore the x because the battery is not charging.

With the adapter I posted about above, I never see the red x and I am charging off USB 2.

To be clear, I am using a 10.1v not a 10.1 - there could be differences, but I doubt it.

Galaxy Note without original charger

Hello to everyone!
I have one simple question: do I risk something if I charge the Note with another charger than the original one?

I don-t know, but I think no.
I charged many time my note with htc charger and gs2 charger.

It doesn't matter what kind of charger you have. The only thing you must look at is the voltage of the source (5V DC) and it must be a micro usb plug

im using my old htc hd2 charger as the samsung one seems to have packed up and isnt charging properly

The easiest way to charge your Note is of course via a USB>Micro USB cord plugged into a laptop or PC (where you are guaranteed the voltage is correct), however if you are using a generic or knock off wall wart charger than provides a micro USB connector there is some small chance that it will not charge your Note.. look for the charging icon and if its not charging, toss the charger and get another.
There is no specific risk to the device, provided that it (the charger) has a micro-usb intended for charging generic devices..its just that some modern portable devices have a stricter requirement (tighter tolerance) for charging voltage and simply will not charge outside that voltage range.. my BB9930 does exactly this..

Since all micro/mini usb chargers have the same voltage, and vary only in the power output - the only problem you could face is slow charging, or no charging at all if the charger doesn't have enough juice. But it certainly won't harm the phone.

I'm using my old Nokia N900 charger without problems

I'm using an old HTC mains-to-USB and a Nokia microUSB cable...

My stock charger has a slight squeal, so I usually use the charger for my BB Curve 9300. Does totally fine.

My Note was purchased from expansys UK but shipped in from mainland Europe. As it was to be sold in the UK, expansys had to supply a UK adapter rather than an EU one ...I received an HTC adapter with my phone. At first, I was worried, but discovered that it works beautifully with my Note. Charges faster than generic Samsung chargers too! You should be fine using another standard charger

For the first 3 weeks I was using a blackberry (original) Bold II charger.
I noticed charge time was too long. And maybe even battery life was shorter.
Im not 100% sure about the second statement but the first is confirmed.
When I started using the Note charger it was faster. Not super fast compared to iPhone or iPad but faster than using the Bold charger.

I never use my samy charger..Im using my DHD charger..no problem at all..

Most modern USB chargers should be fine (I use my old iPhone charger for the Note, for example.) Watch the power output though - some tablet chargers are rated at 2A+ and that could overdrive your charging circuit and cause damage. If you make sure your charger is about 1A (and 5V, obviously) then you should be fine.

Well emuX said it all!
1A of output and 5V and you are fine!

Actually the charging current is limited by internal resistance of the battery, so the battery effectively "accepts" charge. Charging current is not "pushed" in by the charger...
obviously a charger from say a BB is likely to be current limited and so longer charging times would be expected, but an iPad charger will work fine.

I wouldnt worry too much, I charge my note with my iPhone charger purely because the USB port faces a different way so I can actually fit it on my plug extensions without loseing 2 sockets.
Pretty much anything with an output of 5Vdc and a minimum of 1A will do just fine.

Any idea why I can't seem to charge my Nexus 7 with my car charger?
i have both a generic Micro USB charger and I have one of the dual USB ports that you put into the cigarette lighter. It wont even acknowledge that I have plugged anything into it.
i have used the USB port to charge MANY different cell phones my old Dell Streak 7 and even a friends iPad.

I think the N7 needs 2A to charge. a single USB is 500 mA and the dual 1A, so I don't think there's enough power.
Also check if the output of your microUSB cigarette charger is 2A

This one will work: http://www.amazon.com/gp/product/B0090SVY3K/ref=oh_details_o02_s00_i00
It charges at the same rate as the stock AC charger.

The N7 is one picky device for charging. I have several chargers for the car that charge the iPad but not one will charge the N7. Same as AC chargers. This set works for me

This is what I use and it works just fine. I use it to charge my N7, GNote, Nook Color or my grandsons IPhone and it works equally well on all of them.
BTW, it prime available if you are a member.

Charging Issue?

So I am coming from a Galaxy Nexus and was trying to use the little 1amp Samsung chargers from that. Noticed the bundled charger provides a bit more output at 1.8 amps?
Anyways, switched to the bundled charger but the phone complains at me unless I use the bundled cable. Any ideas?

Emailed monoprice support, will see what they say.

I'm having the same issues. All of my microUSB cables give me the error. Anybody know of rated cables that will work? Seems crazy that I get the error with every single one of my cables, but not with LG's bundled cable. I've used these cables to charge a DNA, GS4, HTC One, Nexus 7, etc. with no issues at all.

Might be a long shot but could vzw/att have a setting in the build somewhere that causes this? I know it's a long shot but we all know how greedy they are.

Thanks, I'll give it a shot!

When I used the LG charger & cable my phone charges the fastest I've ever seen any phone charge before.
Anybody know where to buy certified Quick Charge 2.0 chargers/cables? I know my DNA had Quick Charge 1.0 and I loved it, but I could never find more chargers or cables that supported it.

Same here. 50% to 100% in an hour and a half.

Keep in mind that there is a benefit to battery longevity when charging at lower currents.

So heres what they said.
Thank you for contacting Monoprice.com. In regards to your inquiry, the USB specification limits the length of a cable between USB 2.0 devices to 5 meters (or about 16 feet) and for USB 1.0 the limit is 3 meters (which is about 10 feet.) The longer the cable the more power it would require to charge devices and sync. You might need a active USB cable since the LG phone would require more power. At this particular length the power would charge slower. What is the the length of the OEM cable from LG that you're using? With the 1.8A charger with the 15ft cable still slower compared to the shorter USB cables?

[Q] MHL 3.0 lead for Samsung Galaxy Note 4

Hi guys.
Recently ordered the Note 4, and was wondering if anyone else has managed to find a positive 100% working MHL 3.0 lead yet.
I've been searching high and low and not found anything yet beside the usual MHL 2.0 USB 3 leads.
Used to output to my HDMI all the time from my S2/S3/S4/Note 2 etc. But ever since I've had the S5 (soon to be Note 4) I haven't been able to find an MHL 3.0 lead since the old one no longer works.
Tried changing HDMI cable to the latest standard just in case it was that (but it isn't). I know you can get the 5-pin adaptors that supposedly work with the 11-pin for the S5 (and presumably Note 4). Was just wondering if anyone else has had more success, or is it merely a waiting game until someone finally releases a proper lead for it.

MHL 2.0 works fine. Granted you still need external power, but that's no biggy.

Well, currently in my country only Sony have MHL 3.0 cable but it can be useful with Sony 4K Bravia TV, even Samsung doesn't have any product for MHL 3.0. http://www.mobilefun.co.uk/sony-dlc-mc-mhl-3-0-cable-1-metre-p47838.htm
I suggested you pre-order Avier MHL 3.0 adapter http://www.mobilefun.co.uk/sony-dlc-mc-mhl-3-0-cable-1-metre-p47838.htm for future-proof since we can't disclose about the compatibility of Sony cable on any other product.

Why the need for MHL 3.0 ? Unless you've a 4k TV to output to then it's really kinda pointless......

Because at the time I posted it, I didn't know the note 4 could run with mhl 2. Now I do, it's no longer a problem. Unfortunately the option to "shut down" this thread has so far eluded me. Otherwise I would have shut it. But I suppose in the future, some people, who may want 7.1 and be able to use it without external power may want to know.

Newer devices don't need external power for MHL 2.0, at least that's what i've read.

I am also looking for mhl 3.0 cable because its suppose to be able to charge the phone up to 10w of power. Currently with mhl 2.0 adapter I'm loosing battery fast because it only charges slowly, same rate like usb charging

I just bought a newly released samsung MHL 3.0 adapter (part # EE-HN910FWESTA). Once I receive it I'll post back with my opinion. Hopefully it solves the charging issues of MHL 2.0.

I'm on the lookout for an MHL 3.0 adapter too, especially if it chan charge the phone at a decent rate while connected - and preferably with the added bonus of a USB OTG port too - though I'm not sure if/how that would work at the same time as the MHL.
I'll post if I find one...

The Samsung mhl cable needs a power cable to it as the note 4 does not power the adaptor.
But it works. Also note 2 smart docks and screen casting dongles.

Not sure if youve had any luck but I just recieved my Samsung MHL 3.0 adapter Part# EE-HN910FWESTA and can confirm that it passes approx. 1A of power through to the phone using my official galaxy S4 charger while the screen is on and 1.5 when locked. As soon as I leave wotk Ill also test it with video and the adaptive fast charger.

Nah, in the end I just bought the MHL 2.0 lead. Although I was sunrises at how quickly that drained the Note 4 battery, even with power connected and the screen brightness set low.
I'm curious to hear your fast charger results. Have you tried it without external power to see how well it works just off the phone battery? Curious to hear how fast it drains.

Unfortunately I'm getting mixed results. While plugged into a 2a Samsung charger at home I am getting enough juice to charge the phone, however when using it in my car connected to my appradio using a nonoem 2a charger the phone discharges even faster than with MHL 2.0. It looks like I may have to invest in a power inverter for my vehicle, for this to work. Also to answer your question, it does drain pretty quickly.

i bought an ET-H10FAUWEGWW MHL2 cable on Amazon, doesn't work with my note 4 (but work with my note 3)
which MHL 2 cable is working ?

i can confirm that mhl 2.0 is working on note4 and its not some kind of brand name just regular chinese.

Can you give me an MHL 2.0 reference that works with Note 4 ?

So Ive got a Z3 and im wondering which mhl cable to get? Can i use samsungs mhl 3.0 cable? Does the tv need to support mhl 3.0 ?
