H. FAQ on the X5

1)About charging

Q:What power sources may be used to charge the X5?
A:The X5 may be charged by any USB charger with 5V output voltage and 1.5A
or greater output current; in a pinch you can also charge it using a computer
USB port, albeit slowly.
Q:What is the charging current of the X5 while charging?
A:About 470mA through a computer USB port or 1.3A through a dedicated USB
charger (while unit is powered off).
Q:How long does it take to charge up the X5?
A:A full charge through a dedicated USB charger (DC 5V, 2A) takes about 4 hours.
Q:Can the X5 be charged by a portable USB charger?
A:Yes, as long as the charger is capable of 1.5A or greater current.
Q:Can the X5 play songs while charging?
A:Yes, but it is recommended to power off the X5 for charging, to prevent the
charge from taking too long and prevent the X5 from heating up too much.
Q:Can the X5 be connected to chargers via other micro USB cables?
A:Yes, but the micro USB cable that comes with the X5 is specially constructed
with thick power line conductors to minimize power loss while charging. Using
other micro USB cables may lead to slower charging; very poor quality USB
cables may cause so much power loss through the cable as to fail to charge the
X5 altogether.
Q:Why does the X5 charge so slowly or not at all through a front USB port
on a desktop computer?
A:The front USB ports on a desktop computer are connected to the
motherboard through long thin cables, which cause too much voltage drop
when connected to high current draw equipment like the X5.
Q:How to judge the X5's charging status?
A:Below the scroll wheel, there is a charging indicator LED, which lights up red
while charging and green when fully charged. The battery level of the onscreen
battery gauge (on the upper right corner while the player is on, or taking up the
whole screen if the player is off) moves to indicate battery charging.
