Perhaps somebody will be interested...
The CHARGER Doctor was used to measure the current in the following cases. The Note 3 maximum continuous output current is somewhere around 900mA.
Most portable HDDs consume less than 1.0A, therefore, the Note 3 will power most portable HDDs.
Unfortunately, the Note 3 is unable to properly power the new Seagate Backup Plus Fast 4TB portable HDD. The drive operates fine with the Note 3 when supplementary is provided.
The maximum current drawn (benchmarked with A1 SD Bench on Note 3) by the Seagate drive was 1.39A (provided by the Note 3 charger itself.) At idle, the Seagate drive consumed about 500mA.
If a high capacity HDD drive is needed with the Note 3, it is advised to go with a drive which consumes less current.
If using the Seagate drive with an Intel USB 3.0 port on a computer, then I saw currents as high as 1.33A. The same computer port was able to provide about 1.16A continuous.
It would seem that the Seagate drive requires continuous current of greater that 900mA, considering that the Note 3 has been shown to output 900mA continuous and is unable to power the Seagate drive.
P.S. I don't believe it is possible to enable USB 3.0 transfer speeds with a HDD on the Note 3. The only way to enable USB 3.0 speeds on the Note 3 is when the Note 3 is connected to a computer, AFAIK.

Hey, I have the original Samsung USB adapter and I know I can connect USB flash drives, keyboards, mouses, joysticks.... How about an external hard drive? When I connect my 250 GB hard drive the Tab says that is needs high power, but I thought, is there any kernel that allows me to supply high power?
A friend of me told me that he can connect an external hard drive to his iPad 2...
A friend of mine told me I can connect a computer to his Ipad..Oh wait, we can do that already.
Most HDD's that come with 450GB and above already have an attached power supply, the mini HDD's that are 300GB don't need a power supply as it is already been supplied.
Some external hdds with just one usb-connector sometimes need more than 500mA and it looks like the galaxy tab 10.1 just can deliver 500mA (as this is the usb2.0-standard -> https://en.wikipedia.org/wiki/USB)

Lol..
Sent from my Samsung Galaxy Tab 10.1 using XDA Premium HD App.
Thanks guys.
I am going to travel with the DSLR camera and the Galaxy Note only, I would like to use the GNote to upload the photos to the internet, buy using the USB Host connector and a SDXC and CF adapter to USB, I was able to read the small size cards (up to 16GB) but larger ones the GNote said high power USB device and cannot connect to it. Is there a "Powered USB connector", similar to the Samsung HDMI connector that will allow me to power the connector ?, thanks
[5-in-1] RAVPower® Wireless SD Card Reader,USB External HDD / SDD / USB Flash Disk Reader,3000mAh External Battery Pack & NAS File Server & Wi-Fi Hot Spot Wireless Media Streaming FileHub RP-WD01
I just got this about a week ago.....it is nice as heck...works great.
If you want to expand the accessible storage of your tablet or smart phone then this is for you! The RAVPower FileHub RP-WD01 3000 mAh power bank is a portable, self-powered Wi-Fi file hub that doesn't require any physical connection to your device. The FileHub can transfer files via 802.11b/g/n or from external USB hard drives, flash drives, or more portable SD cards and it can add storage to your devices. Pretty much any USB-connected or SD card storage you have laying around will work. I was able to pick up a wide array of storage media. SD card, microsd in a card adapter, Flash drives ranging from 4 GB to 32 GB. (Different brands) It was also able to power my portable hard drive with no problem, all while an SD card was in the SD card slot. I also used many different devices to connect to the wifi disk. It handled every one of them. Bonus, it doubles up as external battery pack. 3,000mah may not be a lot but it does come in handy in those critical must have a charge situations.
The Wi-Fi is great as it can be used anywhere without having to be plugged in. The power bank is 3,000mAH (5V/1A), which will last about five (5) hours. It will charge itself through your PC USB port or for a faster charge.
It can easily fit in a pocket. It has a polished finish. The FileHub is an extremely lightweight device (4.4 ounces), perfect for carrying around anywhere.

I have been a little disappointed when the last few "breakthrough" smartphones were announced. I am a bit of inpatient type and I hate it when it takes time to copy videos from my phone to my computer and when it takes time to copy music from my computer to my phone.
Galaxy Note 3, the first USB3 phone was released in 09/2013. Galaxy S5 (certain variations..?) was the next one to get it. Then in autumn 2014 a suprise: USB3 was removed from Galaxy Note 4, and the recent Galaxy Note 5 still was in microUSB 2.0.
Lets see what is currently possible and with what price. I have a Sandisk Extreme USB stick. 32GB version costs 24eur and 16GB version costs 16eur. This stick has sequential read speed of 200MB/s and write of 89MB/s (according to crystaldiskmark).
Then I did a test for my LG G2. Androbench and A1 SD both give read speeds of abt. 154-170MB/s and androbench gave write speed of 77MB/s (sequential).
When I transfer a movie from LG G2 to my computer the transfer speed is about 27MB/s. So I have a strong reason to believe that the USB2 connector is a bottleneck. From past experience I know that USB2 maxes somewhere around 30MB/s.
The feedback from Galaxy Note 3 was that the microUSB3 connector went easily broken so I was under the impression that this was the main reason Samsung removed the connector from the next model and set its sight to USB type-C, which should be more durable and support speeds up to USB 3.1.
Now USB type-C is finally here but the first four phones I bumped to (Oneplus 2, Nexus 6P, Nexus 5X Lenovo ZUC Z1, or whatever) all of them do NOT have USB3 controller. According to most of latest sources all of them support only USB 2 speeds.
If a 16eur USB stick can do it, why cant a 600-700eur smartphone? I read many different hypothesis of what might be the reason. I just really dont believe any of them
I have a PC with a USB3 port connected to a 3d printed phone holder I designed. It has the power jack built into the base so when I insert the s23 I can accsess the files, pics and videos on the phone as well as fast charge using the high current usb3 standard. When I go to leave in the morning the phone has less than 90% charge as even thought he PC provides power when off over night the phone recognizes that the PC is off and stops charging. My old LG phone and any other device I plug in receives power from this USB connection even though the PC is off. According to Samsung I'm told to use a Samsung Charger. The USB spec was designed to charge and send data. I hate leaving without a full charge. Is there a workaround for this issue? Thanks! ~Kevin www.kevinspage.com

Not phone-related or OEM related. It's your PC (setup) that doesn't supply power to your phone while the PC is off.
You can check your BIOS settings and see if you can configure some of the USB ports you use to deliver power even when the PC is in an OFF state.
Keep in mind that not ALL motherboards support a power delivery while the PC is off.

Been there done that. Already set to power when pc is off. If you read my post you can see where I made it very clear the PC is providing power to the USB port when PC is off. Here is a quote "My old LG phone and any other device I plug in receives power from this USB connection even though the PC is off" My other phone and any other devices I connect get power on the port when the PC is off. I believe some leftist save the planet policy has caused them to program the phone to not charge when the PC is off.

Keep in mind that there are different power states when the PC is OFF vs ON.
You might not get a "full" USB 3.x power output while the PC is off but rather just a limited one like 0.5Amps or 0.8Amps.
Is your base (dock) just a simple "PORT" or is there any PCB built in? Maybe the power delivery is reversed, so your phone is supplying power instead of receiving it.
Custom built PC The phone is not powering the PC. Phone is connected to a blue USB3 connector on the Asrock motherboard with a usb3 cable. Power options set to always on. Charges LGV30 in fast mode just fine when PC is off, but not the S23 Ultra. Win10 is loaded now.

The easiest workaround is to put your PC to sleep, not to turn it off. I charge my phone and watch from my MSI laptop sometimes - when it's turned off its 50/50, sometimes charging, sometimes not, but when its in sleep mode it always charges.
