Frequently Asked Questions

How much power does it draw?

It pulls 48W at full tilt — a standard household outlet handles that fine, and it settles back once it is up to temperature.

What voltage does it run on?

24V, which is standard household here. No adapter, no converter, nothing extra to buy.

Will it work with my phone or computer?

The supported systems are in the specs — this class of device lists exactly which phones, tablets, and computers it plays with. Match your model to the list and you are set.

How long does the battery last?

The runtime is in the specs — days of normal use or hours of heavy use depending on the mode. It charges over the cable or dock shown.

Do I need an app or account?

Check the listing for the app requirement — most pair in minutes with a free app, and the ones that run standalone note it in the specs. Nothing needs a subscription to work.

What can I connect to the projector?

Phones, laptops, TV sticks, USB drives — the input list is in the specs. It throws a sharp image onto any light wall or screen in a dim room.
