1. About charging

Q: What power sources may be used to charge the X3?
A: The X3 may be charged by any USB charger with 5V output voltage like computer, power bank,
and adapter. It's recommended to use the 5V/2A charger.
Q: What is the charging current of the X3 while charging?
A: Less than 500mA through a computer USB port or approximate 1.3A through a dedicated USB
charger as recommended (DC 5V 2A).
Q: How long does it take to charge up the X3?
A: A full charge through a dedicated USB charger as recommended (DC 5V, 2A) takes about 3 hours.
Q: Can the X3 be charged by a power bank?
A: Yes, as long as the current is higher than 1A.
Q: Can the X3 play songs while charging?
A: Yes; no harm will come to the X3 if you use it while charging, in which case it is normal for the X3
to get warm. The reason we recommend turning the X3 off for charging is so that charging
completes more quickly.
Q: What to do if the X3 gets a little hot when playing songs while charging?
A: It is normal for the X3 to get a bit hot in these conditions and this does not endanger the X3 or
the listener in any way. If you are worried about this, it is better to take off any casing to expose the
X3 to air for cooling down. If you're still worried, turn down the volume on the X3 or turn off the
player for charging.
Q: Can the X3 be connected to chargers via other micro USB cables?
A: Yes, but the micro USB cable that comes with the X3 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 X3 altogether.
Q: Why does the X3 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
