I I am looking to put a little charging station in the storage compartment of my home theater sectional. I really would like to only run one USB cable to charge my devices. I am a bit worried I will not be buying the correct pieces for my needs. I bought a 16ft. pluggable USB cord on Amazon recently, but there seem to be worries that a single USB cable may not provide more than 2.1a.
I would like to charge at least two smartphones (HTC One X and Note 2) at once and at their full charging rate. Assuming that this is even possible, could someone provide me with a wall adapter and USB hub that will work for this? I like the looks of...
PowerGen Dual USB 3.1A 15w Travel Wall Charger
and
AmazonBasics USB 2.0 4-Port Ultra Mini Hub
(I can't post links yet).
If this is an impossible task, what are some other good options? I looked at the Belkin Valet, but it appears too large, and has some issues.
Well a note 2 alone takes more than a standard usb 2.0 cord to charge at full speed. Maybe try a usb 3.0 hub and tablet wall charger. Not 100% sure its possible though

Okay, that makes it sound like I might want to change my mind about this whole one USB cord plan. How about running an extension cord instead of a USB cord, then hooking it up to a dual USB wall charger like this-
Kensington AbsolutePower Dual 2.1A USB Wall Charger (Amazon)
Would that work for two Note 2s?
If it can charge 2 ipads then it can charge 2 note ii's

Anybody come across a USB travel charger for the XDA II? I have the USB cable just need a charger that outputs 5v and between 1 and 2amps and has the usual US, UK, EU, Aus and NZ attachements. Expansys.com have one but outputs 5.5v - not sure if that will damage the battery, proporta.com have one also but outputs 9v! Why these chargers don't stick to the standard 5v is beyond me.
not sure what you mean but usb in this context
the connector in the buttom of the xda2 is not a usb connector
and usb cant provide more then 500mA
If you have a usb cable for xda 2 you can acquire a lighter adaptor into which you plug the cable, this will give the correct voltage.

Some power adapters come with USB sockets - I think it should become a standard so with the same cable you can get power from laptop/cigarette lighter/mains. Ericsson used RJ11 cables (modem cable) for it's mobile phone chargers but it never caught on.

Thanks for the link, I have two of them already, looking for something to plug into mains.
Mark,
I think I know what you mean: A plug (either 12v in-car or 110V/230V mains) that supplies just +5V DC on a USB socket.
Received one with my retractable sync'n'charge cable from time168.com (but those guys dont exist anymore).
Also received two with my BT GPS from DConnex.
I would say they are for sale on eBay, at least with the sellers that supply these sync'n'charge cables.
I made an emergency charger myself based on USB: 4 NiMH AA cells (1.2V each) in a battery-holder & wired to a USB socket. Not pretty, but good enough for emergency.
You might want to look at www.javoedge.com. They have a USB retractable sync/charge cable and you can also get adapters that allow you to plug the usb cable into a US/European/wherever plug socket adapter.

I had a look at those - they're not really travel chargers just US and EU chargers and a bulky adapter for the UK.

That sounds like a good idea. Proporta.com have a 9v charger
http://www.proporta.com/F02/PPF02P05.php?t_id=940&t_mode=des but I was thinking AA batteries would be easier to get in an emergency.
Since I only know basic electronics I used 4 rechargeable NiMH cells that gice approx 4.8v alltogether. With normal (alkaline) AA cells you probably end up above 6V. I would not try that . . .
Setback of my solution is to have an AAcharger with me for longer trips.
About the travel adapter: The usb travel adapters I have came in two flavours:
1. Car cigarette lighter use
2. Mains use. I also got a number of 'plugs' with it to make the adaptor fit a variety of mains wall outlets.
Is there a way to charge ya phone through the USB as quick as it would charge through the mains?
It takes for ever to charge through USB?
No. Because USB hub doesn't have as much output as charger.
I know standard usb gives 5V
how much does the wall charger give??
I have a freeloader solar charger, and don't know if I can use the 9.5V output on my desire.

It's not the Volts that's the problem its the Amps
The wall charger provides 1A, a USB connection provides 500mA, so half as much.
Ok thanks people
Never tested never heard about but maybe a Y-cable (2 standard A plugs on one side, a micro USB A on the other side) is what you are looking for. It provides the 500 mA from two individual USB ports. However, you have to make sure that both ports can supply 500 mA individually and simultaneously! E.g. a passive USB hub will not work since all USB ports have to share the 500 mA from the host PC. You would need a powered USB hub.
Get a cheap USB cable extender.
Cut it open.
Short the 2 data wires (white and green)
Tape it back up.
Use this in-between your normal USB cable and your USB port.
anyone ever come across any longer than average account chargers? been trying to find one on the net with no luck. I know I can use a account adapter with a usb port and get a longer micro usb cable but I dont like the thickness and weight of normal usb cables.
Go to amazon and buy a micro-usb sync cable. I got one of those that was like 15feet and plugged it into the wall charger adapter thing that came with the phone
I'm guessing probably not, but the faster charging times would be a great plus. Charging over USB 2.0 seems rather slow compared to proprietary connectors like iPhones, etc. It micro connector should be backwards compatible if you only had a 2.0 cable anyway. It shouldn't impact the design of phones very much since it's just a little wider.
Correct me if i am wrong but It should charge over usb 3.0 faster as usb 2.0 can supply 5v at 500 mA whilst usb 3.0 is 900 mA. Regardless of the connector like the proprietary apple connector it will not charge a device any better as it still is constrained by the usb standard. This is not to say you cannot run more amps though a usb cable connect to a wall connecter as i have a usb wall connected that runs 5v at 1 amp and it charges pretty dam fast.

I don't really think so.
the number of USB 3.0 "actual" user nowdays is still low. and the price for it right now is also ridiculous high compare to the standard 2.0.
But who knows? maybe i am wrong... USB 3.0 is a nice feature to have.
Review/Comparison between Choetech USB Car chargers QC3 USB (Tc002) & USB C (c0051)
(Note this is tested on HTC 10 with a choetech USB C cable)
USB QC 3 charger (Model tc002)
This is a nice little charger, small form and built well. It has a little led in the middle to let you know it has power/is charging. It also comes with usb c cable which is a nice addition.
It has 2 ports, one with a blue strip around it to let you know it’s the “main” QC 3 port. This port gives off 9.1v with 0.83a. The phone recognised this as QC3 and displayed the “charging rapidly” sign.
The 2nd port has no strip around it. It gives off 5v and 1.9a, so will charge slightly slower but still for an in charge charger will charge most phones well.
USB C QC 3 charger (Model c0051)
This is a nice little charger like the above, very similar build wise the only difference being the ports themselves. Please note no cable was provided with this charger. The led also changes from blue to green when charging.
It has 2 ports, 1 usb c and 1 normal USB (USB A). The normal usb port also looks reversible which is a nice added feature. The usb C port requires a USB C to USB C cable.
The normal USB port gives off 8.8v and 1.5a. The phone did recognize this as QC3 and displayed the “charging rapidly” sign.
The usb c port I was unable to read due to not having the right connector to read volts and amps, so I used an inbuilt amp to read the charging speed (Ampere). This read as 1800mA which as comparison is around the same as the official HTC charger that came with my HTC 10. The phone however did not display the “charging rapidly” sign
Conclusions
Both are very good chargers and both available at a reasonable price. If I were to pick one I would pick the 1st USB QC 3 charger (tc002) simply because I feel the double usb a ports give you more options when charging
