Hi guys,
I have an odd question, but I need an answer, specially from one who knows about electronics behaviour. Ok, here is my case:
I'm in a hurry, have to recharge my device fast. Charging using the charger are more faster than using USB-to-PC cable. But while I'm charging, I also need to access my files. Unfortunately, the device only have 1 USB port. What to do? I bought a HTC Y-Cable that provides me with 2 USB port. Now the question is, if I connect my charger to USB Port #1 and my USB-to-PC cable to USB Port #2, does that mean I'm double charging? And if I am double charging, does that mean the charging duration will be shortened (faster charging)?
i'd say yes
normal usb only provide 500mA where the normal ac chager give much more
and recharge faster
so a miniUSB to 2 normal usb connected to a pc would mean both usb connect and fast charge
unless the pc would get confused that it had 2 pda's connected or something
but i doubt it i have a external usb hd which only works with usb only as in without other ac input if it have 1 of those
2 to 1 usb cables and that works
even if i dont use it personly because firewire give me enough power for only 1 connection
I am having trouble charging a Tmobile Galaxy S5. I took it in for repair yesterday and they replaced the charging port. It still barely charges using a USB 3.0 cable. It does charge slowly with a USB 2.0 cable.
I think the phone is seeing the USB 3.0 cable as a 2.0 cable.
Is there a way to tell what mode the phone is currently charging in?
Hi
I have a honor 8 ,with a quick charge feature, it is working with the official wall charger + usb c cable sold with the phone.
I would like to buy a longer usb c cable. How to be sure it will provide fast charge? Could I buy cheapest cable?
Thanks
I'm having issues with getting any (car or wall) power adapter that uses USB A to charge my pixel 2 rapidly. I'm using USB A to USB C cables that charged my Axon 7 rapidly with no issue. Pixel 2 devices can only charge rapidly from a USB C power adapter to USB C only?
Hello XDA members,
I have a problem that I don't understand so I was hoping people can help me out here.
Let me explain:
I have two types of charging cables and one of them is a 3A cable that gives a maximum of 900mA in a USB 3 port or power socket and can not transfer data.
Now here comes the problem I also have a 5A charging cable that charges a maximum of 4000mA in a power socket plus it can transfer data but when connected to a USB 3 port it only gives 230mA.
Why does a 3A cable with a maxiumum of 900mA gives 900mA charging speed in a USB 3 port and a 5A cable with a maximum of 4000mA only 230mA in a USB 3 port.
I can't seem to figure out what the problem is.
Defective cable or product be my guess... with wuv from china.

Hey Blackhawk,
I got a few of these cables and they work perfectly fine when connected to a power socket.
What do you mean by wuv from china ?

Charging is working from the charged device and determines the power needed to charge it

In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); with USB 3.0, it moves up to 900mA (0.9A). The charging downstream and dedicated charging ports provide up to 1,500mA (1.5A). USB 3.1 bumps throughput to 10Gbps in what’s called SuperSpeed+ mode, bringing it roughly equivalent with first-generation Thunderbolt. It also supports a power draw of 1.5A and 3A over the 5V bus. USB 3.2 does not change these aspects of the standard.

It looks like faulty cables or they are usb 2.0 cables

Can a USB 2.0 cable charge faster in a wall charger ?

In theory yes , but If you remember we only started seeing true fast charging un android after the switch to USB C .
Are your cables micro USB cables? If so you are limited in the amount of power that can go through them
Edit : typo

They are both magnetic cables. The 3A charges 900mA on USB 3 port and the 5A charges 230mA on USB 3 port.
The 5A cable can charge up to 4000mA in a wall charger while the 3A is limited on 900mA.
