Most phone batteries have some type of offline charger available on eBay. Have you tried there or seidio.com?

There was tutorial that I read which involves splicing usb wires and connecting it straight to the battery to charge it. Id say if you have any spare usb wires and extra time to give it a shot and even possibly build something out of it. As for things online they make them not sure if ive seen any yet for the X though.

Found it: NOTE: I TAKE NO RESPONSIBILITY FOR DAMAGE DONE TO ANY PHONE, BATTERY, ETC. FOLLOW THESE STEPS WITH CAUTION TO AVOID RISK OF DAMAGE.

1. Take your cable and cut off one of the ends, leaving a standard USB plug at the opposite end to plug into your computer.

2. Now you need to strip about and inch of the wire off until you get to the core where you should see 4 colored wires (red, black, white, and green). The colors don't really matter and they may vary, just as long as you can see a red wire and a black wire.

3. Strip off about a quarter inch of the rubber sleeving on the red and black cables, exposing the actual metal wire.

4. Twist the metal strands of each of the wires a couple of times so that all of the wires from the black cable are together and all of the wires from the red cable are together. This is just to make sure that you don't create a short circuit.

5. Here's where it gets a little tricky. You are going to use this cable to make the phone think the battery is fully charged, when in fact you will just be powering the phone using the power from the USB port. Pull out the battery on your phone and find the 4 exposed metal slots (the battery terminals).

6. Each of the far terminals should be labeled with a plus (+) or a minus (-). What you need to do is put exposed leads on the red wire up to the positive terminal and the leads of the black wire up to the negative terminal.

You can buy 2 non-oem spare batteries and an ac charger on eBay for around $15. You have to wait a couple weeks to get it (from Hong Kong).
