Neat charger for Athena & Jabra headsets

http://www.expansys-usa.com/d.aspx?i=148251
Charges both at same time.

Sweet. I may get one of these.

Do you know how much amps it's delivering? The Athena needs at least 2A to show any sign of being charged!!! I'm suspecting it's only delivering 500mA which is the max amount of amps a Jabra headset can take without frying itself. 500mA is just enough to light up the amber charging light on the Athena and nothing else.

I always thought that a regular HTC charger provided 1A. Do you use a 2A charger?
According to Expansys and PP Techs this should at least give more than 500mA:
The majority of new devices are equipped with two different charging modes: a sync-n-charge mode through a computer USB port (slow charge) and a regular charge mode through an AC/DC adapter or any other charging accessory (fast charge). Those two charge settings require two completely different pinouts and are not compatible with each other.
In select devices, this incompatibility would mean that a sync-and-charge cable for your device, when connected to an AC/DC adapter or similarcharging accessories, will not be properly configured to charge your device.
Our new Lil Sync® Duo Adapter is the convenient solution to this common charging problem. Using our adapter will forces your Sprint PPC-6700 to use the most effective, “fast-charge” mode when plugged into AC/DC power. Additionally, there is a Jabra 8 pin companion port tailed onto the adapter. This allows you to conveniently charge a second accessory such as a Jabra headset simultaneously.
In some cases, your Sprint PPC-6700 will not charge from an AC/DC adapter or other charging accessory when the battery life is below 30 percent. Our Lil Sync® Duo Adapter will charge your Sprint PPC-6700 from a completely drained battery.

Looks like an interesting little accessory.

Yes. I am using a 2A charger both at home and in my car. The one I'm using is the TomTom USB Charger for Go/One/OneXL/XL. Attached are the pictures of the car charger. The home charger provides the same amp. If you're in the US, the car charger is sold at Target for $19.99. The car charger is bent at an angle but the home charger is not. If your car doesn't have bluetooth and you have to use the audio jack on your athena, then you'll need a mini USB angle adapter to reposition the cable upward. The mini USB angle adapter comes standard with the old Motorola Razr V3 so if you already have one of those phones, you don't have to buy a new adapter. Otherwise, the Motorola mini USB angle adapter is sold for a few bucks where Motorola phones are sold.

Using other chargers

Can I use chargers from other devices that also use mini USB such as my garmin GPS or will they damage my X1?

ive never actually used the charger that came with it(it came with the ugly European plug). if you are going to use a standard USB charger,dont go with one that has higher amps than the official one (i think its 700 miliamps if im not mistaken ) just to be sure
that said. i used the charger for the following devices to charge my x1 (some charge faster than others): Atom EXEC, samsung digital camera, htc wizard, motorolla dumbphone, usb pc cable, xbox360, g1

I charge mine via mini USB cable from PC, mains adaptors (2 different ones), 12V cig lighter adaptor.
BTW PC seems to be the slowest at charging.

Thanks....
Back to OP:
Yes, but it is not advisable. Check if the other charger has the same specs first.

USB is a standard isn't it? I don't think your at risk frying your XPERIA. If it managed 220 in Europe it will manage 110 here. As for me, I've charged my phone with everything, a USB cable connected to my computer, a car ciggarette charger that came with my Tomtom, and my friends iPhone charer. All worked flawlessly.

yes usb is std
it give 5volts dc
and charger which provide
5volts in the correct usb connector
can charge the device
nothing else matter
amps don't matter as long as it's more then 0.5

From my understanding, if the charger allows 1A, then that is the MAXIMUM it will provide, it won't be trying to supply that all the time.
So if the X1 wants, say, 0.6A, then a 1A charger will work. On the other hand, you wont want to use a 0.5A charger if it is trying to draw 0.6A or whatever higher.
This is just how you can have a massive 900W power supply. You can draw 200W, 300W, etc. but you can't have a 300W power supply and try and draw 500W (unless you like smoke, fire, explosions, etc.)

John is correct. The USB standard 5V is the important bit. Doesn't matter if the device can supply 0.5A or 5A. Most PC USB ports are good for 500mA, the OEM charger is good for 750mA.
A few of my friends have Motorals RazR's that charge via a mini USB, I don't have to worry about packing a charger when staying overnight.
I already had a collection of USB style chargers and mini USB cables before I got the X1. Use my laptop or a Belkin charger (1A) I got for the iPod in the lounge room, a generic USB phone charger in the car (500mA), the OEM SE charger in my bedroom etc, etc.
At 1st I thought oh no, my 3rd SE phone, my 3rd type of memory card and 3rd tye of charger - but I was a winner with the mini USB

USB Cigarette lighter chager

I have an old usb cigarette charger - output is 5.5V 500mA. Will this be okay to use with X1 or should I buy an official one?

My 650mAmp charger does it well enough, yours will probably too.

it is the same voltage as usb port so it should work

5.5V or 5.0V?

I use the blackberry lighter charger, 5.0 v 1A
Is it OK ???
I think I got the answer http://forum.xda-developers.com/archive/index.php/t-505222.html

volts is the only thing that matters amps are drawn and a device will draw as much as it's made to be able to the more it can draw the faster it can charge
usb is spc'd to be 5volts but would think that 5.5volt would not cause problems but
once I gave my ext usb hub 12volts and it killed it and many of the devices connected to it

So, using a 5V 500mA just to keep my X1 alive while navigating should be no problem, right? I hardly believe it'll need more.

I use the car charger from my navigation pocket loox by Fujitsu Siemens.
This works great with output 5 V 1 A.
The original charger for home has only just output 5 V and 700 mA.

i never use my sony charger because its not charging properly
i always use motorola charging because its micro usb charger the same as X1. no problem so far

charging cable for X1

Can i use a non sony cable for charging my X1 or USB transfer? It looks the same as a USB mini connector that i have but i'm not game to test it without your advice?

Yes you can. The only comment to make is the number of connectors in the cable. Almost all cables will charge & allow you to connect with your PC, a minority may just allow charging.
(I once bought one of those roll-up cables from Boxwave, where the cable is collected in a disc: it was sold as a charging cable, and yes, it only charged! In the same box there was a synch cable of the same design, and that both charged and sync'ed)
And re the charger, you can use any. Charging from the PC is slower, as will be some wall chargers with a low rating (amperage).
But you will not damage the phone, however much power (amps) the charger promises to provide: the phone will only draw the current it needs.

Thanks for the reply. I'll test my cable.

x1 is miniUSB a universal std like a normal AC connector
even other htc devices with extUSB rather then normal miniUSB is direct compatible with
all miniUSB cables for charging and syncing with computers

[Q] Compatibility with car charger on 1.5A and 5V

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.
