Portuguese Windows OS but language can be changed by downloading preferred language for text / web browsing or install an English version of Windows yourself.

If you speak Spanish you should be able to navigate through the start up since it's a bit similar to Portuguese! If not use some translation tool.

Reset Ready!

Comes with OEM Charger.

Working! All buttons work, charges fine. 

Used it and had it on for a couple of hours & no issues.

3 USB Ports, HDMI / Ethernet / SD Card Ports.

Unsure of actual model, but seems nice. Not too old of an interface / usage.
