Hi all,
I was a Kickstarter backer for PLX Devices's Legion USB Meter. It will report voltage and current inline with your USB charger and cable. It is really useful for identifying bad batteries, crappy chargers, etc. Where it falls short is that it measures BEFORE your USB cable and so your measurement doesn't take into consideration voltage and current loss through crappy cables, or just long cables. This, for me, is a problem.
So, I would like to find a way to adapt this Legion meter so that I can put it on the phone end of a cable. I know there are still some inaccuracies with what I am trying to do, but it should still be useful for comparing current before cable and after cable.
I need a way to plug a standard micro-USB cable into an adapter that has Female Micro-USB B on one end and Female USB A on the other end. Then, I would plug Legion Meter into this Female USB A end, and then a VERY short cable of high gauge into the meter and then into the phone.
Thoughts?
This is probably going to be a stupid question, but have you checked eBay?
Are these what youe looking for?

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.
What with having had many many HTC devices over the years I've got a few chargers lying around.
Standard type... 5V 1000mA Mini-USB.
I've bought a couple of Mini to Micro USB adapters and these chargers work, but not properly.
They are registered as charging over USB and not AC, meaning the charging speed is much much slower than using the original AC charger. I don't have an issue using the original but it'd be nice to make use of the chargers I have lying about.
Any ideas why they're being recognised as USB and not AC?
Is there an inncorrect pin translation with the Mini to Micro USB adapters?
I also read another thread where someone using a different Micro USB cable had slower charging speeds, is this related in some way?
According to knowledgable members on other threads, the phone recognises the AC charger when two middle pins are shorted. Perhaps this is a new method for the Desire, and your old chargers dont have the pins shorted, therefore not signalling the phone correctly.
Check the navigation and charging thread.

Hi Experts,
i have a HDMI cable that i use to connect my HTC One X to my samsung smart TV, thts of type -
http://www.ebay.in/itm/MHL-Micro-US...1?pt=LH_DefaultDomain_203&hash=item3a85d7b7a7
Now i want to extend the wire for another 1-2 meteres.
So basically, i will need a wire that is of the type of the charger, but female to male.
Whr do i find such a wire, what is it called, what do i search for on ebay?

would probably be more reliable if you bought a mhl (male) to female hdmi, and female micro usb to charge. then you can just use whatever normal hdmi cable you want to use. if you start mixing lots of cables and extending etc you could run into problems. It could also work. But just warning you.
If you want to stick with the cable, just google for female hdmi to male hdmi and there's lots around.
A lot of the time cables are made to a certain specification. The HDMI Specification can be found here http://www.hdmi.org/manufacturer/specification.aspx
Although the HDMI Spec doesn't mention a maximum length for an HDMI cable, signal attenuation limits the length of most cables. That's why you won't find many HDMI extension cables, they just aren't recommended for any kind of quality signal use.
As for MHL (which is the cable that connects to your phone), I reckon that would suffer the same limitations as HDMI.
Hi all,
I need a new USB cable for Android Auto in my car. Having some problems and want to start by ruling out the cables as a problem. (Pioneer have told me the cable included is not usb-C certified). It needs to be plugged into the back of the Pioneer unit which involes removing half of my car interior, so I want to buy a good cable and not have to do this again any time soon!
So it needs a 'male' end to go into the back of the unit, and a 'female' end which sticks out of my glovebox permanently. Then I'll need a second cable (a usb-a to usb-c to attach the pixel.)
Having seen all the news about dodgy cables and Benson Leung (Spelling?) approved cables I confess I'm more confused than I've ever been. Plus the options seems less with the male to female cable and I can't find any recent online reccomendations.
Can someone either tell me what I need to look for, or preferably, link me to a high quality male to female cable on Amazon UK? and of course one that's certified and will play nice with the USB-C device (my first gen pixel) that's gonna be plugged into the other end.
Getting the other cable is less of a problem, there seem to be plenty of lists online for recommended high quality usb-a to usb-c cables.
Thanks in advance for any help.
Ok - this may be a silly question but I'm looking for a shortish cable that has a USB-c Male with a USB-A male AND a USB-A Female plug on the other end(s)
I've tried googling but all I find are usb-c males with either just usb-a male or usb-a female connectors on the end
The idea I have I could plug my phone (motorola Vision One) using the usb-c, have it connected to my pc (usb-a Male) so I could transfer file to/from pc (while the phone gets charged as well) & have a USB Stick plugged into the usb-a female connector (not sure if it is even possible to have a 'split' data connection to a Stick & pc at the same time)
Yeah - I know I could plug in the stick into another usb slot on pc but I might need to transfer stuff from phone to usb stick while away from computer but still be able to charge the phone up from a mains plug
If you're not sure what I mean here's a bad photoshopped picture of what I'm looking for
The 'best' idea I can come up with is perhaps a usb-c to 2 usb-a females & getting a male-male connecter/coupler pluged that into one of the {f} connectors, but I what to have as little stuff to carry around without the possibility of loosing any adaptors etc
Any suggestions or comments appreciated
Thanks in advance
