  • Adding an external power supply to a cheap USB hub

    So the more powerful the adapter, the more current available to ports, and yes everything is now crystal clear, thank you, plus I found some valuable information in previous comments and other websites (I should've done some reading first), and the questions are.. well, not repeated.. but indeed dependent on each other.Thanks alot for the quick reply, and I've done it already and testing it now on various devices, I just want to measure the voltage and the current on each port during operation, will that affect the function of the devices? like causing data loss or corruption if there is a data transfer going onI'll be using something like this :

    I'll be very careful of course :)and the tests went OK, I only experienced issues with a usb wifi adapter, the connection was poor and kept dropping, I changed the usb cable and the dropping gone, but the connection still poor, (the usb wifi adapter worked fine on that hub before), I think there must be a noise somewhere, do you have any idea where it comes from?, or maybe there is another reason in your opinion.Thanks

  • Adding an external power supply to a cheap USB hub

    I have a few questions here..Can I use one of the USB ports available on the hub to power that hub?What I mean is this :1- I'll get a male to male USB cable.2- I'll plug one end of the USB cable into a USB charger (2.0A, 5V).3- I'll plug the other end of the USB cable into one of the ports available on the USB hub.4- I'll cut the hub's VCC red wire as you mentioned above.so.. 1- Will this work?2- Will the hub then provide the correct power to the rest of the ports (500mA,5V for each of the 3 empty ports)? "assuming it is a 4 ports hub of course", or doing so will need extra steps and procedures? 3- Assuming all ports working at full capacity, if each port requires a 500mA, 5V, so for a 4 port USB hub, wouldn't that require at least a 2.0A, 5V adapter? or will any adapter work?...see more »I have a few questions here..Can I use one of the USB ports available on the hub to power that hub?What I mean is this :1- I'll get a male to male USB cable.2- I'll plug one end of the USB cable into a USB charger (2.0A, 5V).3- I'll plug the other end of the USB cable into one of the ports available on the USB hub.4- I'll cut the hub's VCC red wire as you mentioned above.so.. 1- Will this work?2- Will the hub then provide the correct power to the rest of the ports (500mA,5V for each of the 3 empty ports)?

(say a 500mA, 5V), how this works actually?4-Will it be safe to plug my stuff then? USB HDD, external drives (DVD, HDD ..etc), flash drives, card readers ..etc, I mean will there be any extra power delivered to them somehow because of the charger or the cable specifications? do I need to be cautious of same?5- Can I use some or all of ports this way to charge multiple devices while using the hub for data transfer? (mobiles, tablets, power-banks, speakers ...etc)6- Will the hub provide only 500mA, 5V for the ports used for charging? or will it provide more for the charging processes?7- If it will provide more for the charging processes, will that need a more powerful charger? or will my 2.0A, 5V work just fine?8- And finally... is there a USB hub that already does all of what I have been asking about? (I mean powered by one of its USB port (or just a separet USB port), and can be used for data transfere and charging at the same time, with adjusting the specific power each port recieves? like 500mA, 5V for normal operations ports , and 1A, 1.5A, 2.0A 5V for charging ports)Sorry for the too many questions, and this was very useful indeed! thank you!
