Hi, i need a spare charging cable and was wondering where to get a good one from.. UK.. preferable not the usb c to usb c you get with the phone i want usb c to normal usb so it works with my power banks etc.
you may see a slower charge speed but but then that is likely with most power banks as Samsung picked an awkward collection of requirements to use full fast charging, but really any USB3 lead should work for a power bank as chances are the powerbank can't output the full charging speed for the phone anyway. I would just recommend using the stock stuff in the house.
Thanks
Im using my old Note 9 charging cable, with a fast charging power bank by Samsung... and with a multi usb port extension. I don't want to keep plugging it into the wall, i use it a lot often while it's charging

I am considering buying this usb charging adapter cable to help speed up my charging rate at work where I don't have an AC adapter and my work computer's usb ports are conveniently placed. From what I have read, normal usb charging maxes out at 500ma, but can be increased if your usb port has more juice if you short the data wires, which will tell the phone to grab more power because it thinks it is plugged into an AC adapter.
I have found this adapter http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
it is meant for a galaxy tab, but From what I see is that it has a switch that either allows data / slow charge or allows quick charging. I have purchased a few of these already because I'm assuming it will still work with my galaxy s2.
I'll let everyone know how it goes, but does anybody see a problem with this or think I'm going to fry my phone for any reason?
Thanks.
very interesting, heck it's only $3 bucks, might as well just buy it and find out
yes, charging via USB port sucks, it's too slow at 500 mAh
if that does the magic trick, by shorting it and making it believe it's an AC then it'll be nice, and it can pull around 1000 mAh off the USB port (depending on your computer mainboard)
Id be curious to see if this actually works but i see no fault in trying it

Only the Galaxy Tablets have this limitation (they cannot be charged at all via computer usb only via their "special" wall adapter) so the adapter won't do anything for a phone. The adapter works on the tablet because what the adapter is doing is shorting 2 pins on the USB cable to fool the TABLET into thinking it is on the AC adapter "specially made" for it.
As long as you plug the phone it into a self-powered usb port (ie: a hub with a power brick) you will get max current the phone allows. The adapter will make no difference on the phone because the phone CAN charge off the PC port while the tablet cannot. It won't hurt the phone but it won't help it either.

Thanks for the info on the galaxy tab, however I disagree with you in your opinion that an adapter that shorts the data wires will not help the phone to charge quicker.
It seems either the devices or android system itself limits charging to 500ma so it does not damage the computer, the phone itself knows that it is connected via usb, and will state "Charging: USB Plugged"
If you let the phone think it is connected to an AC adapter, it will allow the battery to accept whatever amperage you throw at it, and you will see that the system states "Charging: AC Plugged"
Obviously there are two modes of charging going on here.

Has anyone tried this yet?
I have found that using the Galaxy Tab chargers works the same way. They have a 2amp output vs the .5 amps that most blackberry chargers and USB use... It shortens the charge time significantly.

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
So the note III is the first smart phone to use USB 3.0 this raises some interesting questions. First of all I’m a neophyte with electrical “stuff (to use the technical term) so I apologize if some of this is easily answered (which would be great).
1. Since USB 3.0 can draw 5 Voltsdoes this mean that the current crop of car chargers won’t charge the Note III at full speed. All the car chargers I’ve seen are 2.1 Amps (some are dual port and claim 4.2 but that’s total, not in a single port). Does this mean that we’re locked to slower charging in the car?
2. For those of us with built in DC/AC inverters, would we be better served by using that plug and a wall USB charger? If so which one, my Note III will be shipping soon, so I’m assuming that 1000mA is still the maximum (I think USB 3.0 supports 900mA).
3. Will the note III charge slower using a USB 2.0 cable even with the best inverter/car adapter
4. Do we need a “charge only” cable (like http://www.amazon.com/Specialised-Micro-USB-Cable-Charging/dp/B0088HTYUE ) to achieve the best charging speed ?
5. In the event we can't get an optimal charger will the note III charge faster with a 2.0 charge only cable vs a standard USB 2.0 (I assume so but better to ask).
The move to USB 3.0 only affects charge rates connected to a PC. 2.x is limited to 500mA while 3.x is 900mA I think. Both standards use 5V, but 2A AC chargers often run a bit higher at 5.3V. The chargers don't directly adhere to either USB spec and basically trigger fast charge the same as before, by shorting out or putting a fixed resistance between the data pins. My old HP TouchPad USB 5.3V/2A charger with 2.0 cord charges my Note 3 just as fast as the Samsung 5.3V/2A adapter with USB 3.0 cord does. If you look closely, you'll notice that the "USB 3.0" Samsung charger doesn't actually have the extra 3.0 pins, it uses a 2.0 port. That's because for pure charging devices the standard doesn't matter, only the current and voltage rating and that it shorts the data pins.

Thanks for the response.
So I should use a "charge only" cable, correct?

If you want maximum charging out of a PC, yeah, otherwise it really doesn't matter. Also, if you use a fast charge kernel with fast charge enabled, it does the same thing by forcing the charger detection in software rather than in hardware. That said, you're still at the mercy of your USB port. USB 2.0 ports on PC's are only rated for 500mA usually and while you can overdraw from most without issue, you run the risk of overloading and at least triggering a software shutdown of the port (at worst, burning up the motherboard's power regulator for the USB 5V rail).
If you're plugging a cable into an AC adapter, it literally means nothing. All a "charge only" cable is is a USB A to micro B cable with the two data pins on the micro B side shorted together. Only the GND and +5V lines are wired through to the USB A connector which makes it only draw power, not data, and the shorting of the data pins makes it detect as an AC charger. Since the AC adapters short the data pins already, both cables look the same on the phone end when connected to an AC adapter. Same goes for a car adapter or external battery pack.
Technically, USB 2.0 and earlier, maybe 3.0 as well, are only supposed to let you draw 100mA. Devices must enumerate themselves to the controller and request the power limit be increased to 500mA. Many motherboards are pretty lenient about this so you can usually get away with plugging in a 500mA (or higher) load without telling the PC first but be aware it's breaking the specification and could be unsupported.
Some PC/laptop are BC 1.1 compatible. Meaning they can charge higher than the 450ma they usually do. I think it allows for up to 1.5a charging but don't quote me on that I forgot. I have a USB 2.0 hub that can use a wall charger and allows one device on any of the 4 ports (automatic sensing) to charge higher than usb2.0 specs. There are some hubs that allow all ports to do this. I am waiting for plufable technologies to update their 3.0 hub to do this.

It is the normal case that the speed will be much slower when you charge a device such as your Note3 via USB than via DC Power Supply. USB is mainly designed for the communication. The standard charging current of many mobile phones is 1 A or higher. But the highest output current of USB cable is only 0.5 A which could not reach the source demand of a phone. Except for this, we do not recommend charging via USB because the unstable current output can easily reduce the battery life of your Note 3.

Now that's something I never thought about. I would always plug my old phone into my computer when I got to work just to keep it topped off. Though lately, I'm plugging into a powered Belkin hub, so hopefully the current is more stable.
Now that I've got a new phone, I may rethink my charging strategy.
When I use the samsung cord through USB on my PC it charges VERY slowly. Is this normal? I find the only way to get a fast charge is through the standard usb cord and adapter connected to the wall. Any help is greatly appreciated.
Yes. PC USB port gives out less power then a wall outlet. The reasons you can charge phones with a pc is that phones have smaller battery's and do not need a lot of power to charge meanwhile, tablets have a bigger battery in which means that tablets use more power because of its components and screen. That's why tablets need more power to charge fast. You can charge the tablet on a pc but it would be really slow vs a wall outlet

Ok great thanks for the reply. Just wasnt sure if something was wrong with my battery.
BUT - If you use a powered USB Hub on your PC that is 2 amps or better it may charge as fast as the wall unit????
Hello
I understand that this may be a somewhat stupid question but I appreciate your patience with me.
Basically, I have a few power banks which have the CE and RoHS marks on them and they've been charging my MicroUSB devices without issue for sometime now.
However, I'm aware that there are some potential problems with certain Type-C cables and devices regarding current and the USB specification, which brings me on to my question.
Is it safe to charge the OP3 with a portable power bank and the supplied Type-C dash charge cable? I understand that obviously the phone shan't fast charge, but will it do any harm to the battery to charge it this way?
Thanks a lot for your time.
Yes, you can use the supplied cable and the power banks to charge your OnePlus 3. I charge mine with my Anker power banks and even with the solar charger. Do stay away from third party USB C cables for the reasons you've mentioned.

The original charger charges at 5V/4A. This means that the cable can handle 5V/4A. You can charge, but don't go above 5V or 4A. Hope i helped.
Thanks a lot!! I can relax now and just enjoy using the phone while travelling. )
Have been using my Zerolemon Toughjuice to charge it at times when I am travelling and it works fine. You should be good.
Although I have two official razer branded chargers which are fine I'm trying to reduce the amount in carrying around and for day to day usage the phones 4000mah battery has not dropped below 15% yet.
I'm planning a trip soon so wanting to cut down on what I am carrying however USB C is now my main standard so you would assume carrying a single razer wall plug with usb is enough.
Currently using
Razer Phone - USBC
Razer Headphones - USB To Micro USB
Razer Nabu - USB to non standard
A RavPower power bank 26800mah with USBC and power delivery.
My Nintendo Switch
The standard razer plug works to charge all the above however the non USBC devices will need to be in the power bank so wanted something as good but with a standard usb port too. Which is why I saw the below and wondered if it was any good to charge the phone as it supports outputs the phone charger doesn't. I don't know much about this so wanted to check it wouldn't damage my phone.

it will not charge as quickly because its a different quick charge tech than Qualcomm's QC 4+ thats on the Razer. if you want to have both ports then its fine. otherwise invest in a cheap usb-c to usb adapter and use existing plugs:

Thanks for letting m know i wont bother getting it then as the Razer charger charges everything i carry and the non usbc stuff will just have to be powered by my power bank.
Sorry if mods didnt see this related to the phone but i was trying to figure out the phones power options with some reason to why i didnt just want to use the supplied power block.
