Hello,

I would like to buy a charger for my Xduoo X3 II so that I don't have
to turn on my computer just to charge the device, but I don't know
what's safe to get as I'm a complete noob when it comes to things
concerning electricity - I don't want to damage the player by
connecting it to something inappropriate.
The official site says that the unit has a "DC 3.7V/2000mAh built-in
li-polymer rechargeable battery". So, what should I look out for when
searching for a suitable charger/adapter? Practically all the chargers
I've seen are 5V - would this be a problem?
On a related note, the official sources mention that a slow charge of
the X3 II should take about 5 hours and a fast charge 3 hours. I have
realized that all my charges via my computer's USB port have in fact
been slow ones. Would a rightly chosen power adapter charge the player
more quickly and if so, what would its parameters need to be?

Many thanks and have fun.
Matej
