Review on Enhanced Productivity: HumanCentric Portable Monitor Consoles with Magnetic Built-In Speakers and IPS - Model 301-1023 by Fort Mascho

So I wanted to emphasize that the portability of this monitor is that it is small and light. THEY MUST ALWAYS BE CONNECTED TO THE POWER SUPPLY. We bought this monitor to allow other Nintendo Switch games to be played in the car, so we had to buy a battery. It also doesn't charge your device. So when you want to game with the Switch, it stays connected via HDMI and no longer has power.
