Hi, I'm new here and my first post on XDA forum, please excuse for any incorrect terms. I received my OP3 last week and looking for to buy more USB type C cables and chargers to use at home and in the office.
There are several post regarding USB type C even from Google tech guy Benson Leung, but after reading them, I was still unclear. As my understanding OP3 uses DASH which is charging at 4A, thus drawing a max of 4A from the cable and charger. The available type C chargers and cables (type A to type C) on mainstream are 2.4-3A which are used by majority of the devices on the market. So in theory my OP3 can use the mainstream chargers and cables, but take longer to charge. However there is a warning: "Only use cables following the specification otherwise you can risk damage to your USB hub, USB ports on PC, or AC Charger if the phone is requesting to charge at a current of 3A and the charger cannot support it!" (in our case it would be 4A)
The easy option is to buy the DASH charger and cable from OP at 4A, but how compactible will it be for other devices. Will it also work on the mainstream devices, or will it cause damage due to the larger output? TBH I'm not to bothered with the charging times, I'm more interested in the compatibility/future proof of the accessories.
Thanks in advance for the replies!
The phone draws the amps it needs. I'm pretty sure all current phone chargers output 5 volts so no need to worry about that. There are a few different quick charging technologies and AFAIK the OP3 only supports Dash and Dash only supports the OP3. From what I've read the Dash cable is just a USB C cable that's thicker and has extra pins for the extra amps.
Dash charger + Dash cable + OP3 = Dash charging, 4A
Dash charger + Dash cable + other device = Normal charging
Dash charger + normal cable + OP3 = Normal charging
Dash charger + normal cable + other device = Normal charging
Other quick charger + Dash cable + OP3 = Normal charging (AFAIK, some say that OPPO quick charger allows quick charging)
Other quick charger + Dash cable + other device = Depends on device, if the quick charger and device are compatible with eachother the Dash cable should be able to provide the necessary current
Other quick charger + Normal cable + OP3 = Normal charging
Other quick charger + Normal cable + other device = Depends on if the other quick charger works with normal cables
Normal charger + Dash cable + OP3 = Normal charging
Normal charger + Dash cable + other device = Normal charging
Normal charger + Normal cable + OP3 = Normal charging
Normal charger + Normal cable + other device = Normal charging
Your best bet would be to buy a Dash cable and a quick charger that works with your device. AFAIK other quick charging technologies don't need cables capable of providing more current than the Dash cable already does.
thanks :good: nakkivene for a detailed reply, it was very helpful. I will get the DASH charger and cable, at least the thicker cables are somewhat future proof.

Hi,
a friend of mine have gifted to me a car charger that is incompatible with my Legend, because is miniusb (with output: 5V - 1.5A) and the regular charger in bundle with the phone is microusb with output: 5V - 1A.
Can I use the car charger, with a differte cable (the car charger can use usb cables), or the current in output is to much for the phone?
It doesn't actually matter how powerful the PSU (power source unit) is, even if it was 5V / 10A you could still use it... To put it to easy talk, the phone will just take what it needs. The important parameter is Voltage, which is OK - 5V

That's not quite true. The power does matter, but only in a limited way. The voltage (volts) must match. The current (amps) or power (watts) rating of the supply must be at least that which the device draws.
So in this case; yes, you are absolutely fine. You just need an adaptor to make the plug fit.
My work phone has a mini-USB socket, but requires 1.5A to charge successfully, which is three times as much as standard USB. My personal phone has the same socket, but will charge when connected to a conventional USB host like a laptop, which only supplies up to 0.5A. I can use any USB charger with my own phone, but I can only charge my work phone from its own charger.
Apparently I've not made enough posts to include links, but you can google "Charging Batteries Using USB Power - Maxim" and click on the first link, as long as you don't mind reading a moderately technical document.
Don't nitpick I'm an engineer so I know how these things work end to end, If you have power and a good charger (not meaning the car charger, but the actual charging circuit handling the battery charging inside the phone) you can charge even from 5V / 200mA It'll just take more time, of course you'd have to add more than the phone consumpts, but if you do that you're basically OK...
What you're referring to is USB charging, we all know USB doesn't have to have full 5V but in case of charger, there will be 5V...(possibly even more when open)
I have this car charger with 5V and 1000mAh
http://www.ansmann.de/cms/de/consumroot/chargers-and-power-supplies/universal-chargers/carcharger-micro-usb.html
and i must say it is worse than the Original charger for the Wall outlet from HTC -- it takes about twice as long to charge the phone.
And when i use my phone for Navigation it even slowly discharges the phone - which is truly annoying!
EDIT:
I did some research: on original HTC Chargers the Data+ and Data- pins on the micro-USB-connector are short-circuited to tell the HTC-Phone that it connected to an original charger - only when the phone realizes this, it charges with 1000mA!!! Otherwise it only charges with the USB-specificated 500mA
You can easily check this when you charge your Phone with a 3rd-Party charger, go to:
Settings-> Telephone-Status -> Battery
Here is usually written charging (USB)
only with original chargers you get "charging" (AC)
I opened the connector of my Car-charger and short-circuited the Data+ and Data- --> Now it says charging (AC)
I still have to test if charges faster now, and charges the phone while navigation - because until now it discharges while navigation, despite being connected to the Car-charger.
So to say it short: If you want to quickly charge your phone in your car buy a original HTC Car charger, or short-circuit a 3rd-Party one.

don't worry you can charge your phone with no problem
i have the same 5V 1.2 A ,it's charging with no problem
It's good to have stornger charger. Probably you wil be able to charge your phone faster But it always have to be 5V.
Hi,
Will charging the phone using a usb extension + original usb cable will make the charging much longer to be full?
The longer the cable, the less voltage reaches the battery. I've experienced this as well.
It depends more on the quality of the cable (section), than it's length.
Anyway, charging from a usb port delivers only (more or less) 500mA, from the power adapter : 1000mA, so except if you have one of those recent gigabyte motherboard including the ON/OFF CHARGE feature (enables ~1000mA output to usb ports), it's always better to charge from the power adapter.
I've been searching around, and haven't really found an answer to this. I'm in the process of purchasing a car that has OEM AA, but unfortunately only one USB port, which apparently provides less than 1A of output. There is a 12V outlet in close proximity to the USB port. Are there any solutions out there for using AA while also providing higher amperage charging? Was thinking about trying a small hub/adapter (similar to what you would attach to a USB-C Macbook) but I wasn't sure if that would pass-through power as well. Using a stock Pixel 2.
Probably its not easy to achieve, but usually this is not a problem, you can still buy a different charger for rapid charging which works via the 12v outlet, and when its full or nearly full switch to the AA port, since even if its lower than 1A it will be enough to charge the phone ( or better: to not let it discharge) since the display is off during AA session
I use a USB Y Cable (https://www.startech.com/Cables/USB...xternal-Hard-Drive-USB-A-to-mini-B~USB2HABMY3) with a USB Mini to USB-C adapter.
I don't get the "Charging Rapidly" notification on the lock screen, but it does charge noticeably faster than before.
Looking at this article it seems like an upgraded cable could charge a device faster. If the phone shows "Fast charging" can that be improved upon? Could a USB PD cable charge faster? Is the cable that came with the phone the best?
It is true that the cable intervenes with the charge the battery receives, but, in the end, there is a limit in the charge the charger itself can supply
I have used a couple of different USB Type-C cables that are said to be suppose to offer much faster charging speeds than the bundled stock Samsung Type-C cable. Honestly I don't notice a difference in charging speeds.
The real proof is always testing with a USB wattmeter and a phone that has less than 80% charge (screen-off).
The most I get out of a stock charging brick and a Anker Type-C cable is 18 Watts. Stock cable gives me 16 Watts under the above conditions
So there are two interesting threads going on... One about USB C Hubs and one about how the Tab S8 Series Super Fast Charge protocol works in real life. I'd like to see what people say about power pass-through with their USB C hubs. What it comes down to is that the Tab S8/plus/ultra really wants 10V @ 4.5V, but most chargers max out at 9V @ 3A or if they support PPS, 10V @ 3A. For hubs, I don't know what "PD Pass-Through" means or how it works and if it supports the PPS format Samsung wants. Many hubs say "support 100W 3.0 PD Pass-Through". What does this mean?
My UGREEN 70411 hub says it supports 100W PD 3.0 pass-through charging. But when I use the same cables and power supply, the charge going to the tablet battery drops precipitously with the hub in the chain:
65W PD 3.0/PPS power supply --> Tablet gives Super Fast Charge 2.0 with Ampere reporting 7A @ 4.12V charging the battery i.e. 30W
65W PD 3.0/PPS power supply --> 100W USB C Hub --> Tablet gives Fast Charging (not Super Fast Charging) with Ampere reporting 2A @ 4.12V charging the battery i.e. 8W
So it isn't even close to "passing through" the power.
Does anyone get better results? Do we need anything special in a hub to "pass through" the PPS protocol Samsung actually requires? Do I just have an old hub that doesn't support PPS?
Thanks,
Joe
I have the same issue. Using a brand new Anker USB C hub. No matter which high quality cables or 100w chargers I use, or mix of peripherals plugged into the hub (I use a 4k monitor and an SSD), the tablet doesn't charge. When the tablet is plugged in, and the cover is closed or screen is off, it charges as it should. Would really like an answer as to why this is, or a workaround. I'm trying to justify this as a laptop replacement, and inability to charge whilst simultaneusly in use and 'docked' is a potential dealbreaker.
