Before you need to rely on it, make sure you test it out with the X at a low battery, if it's limited to 500mA (like a lot of USB chargers) you may find that it can't keep up with the X's power consumption. It'll draw more power if it's low on juice, so don't test with a full charge. If it works, good find!
