Review on NexiGo 2021 4K Portable Monitor Computer: Premium 15.6" Screen, Stunning 3840X2160P Resolution, PM4K15-AM02, HD Display by Leeboi Portillo

I've been using it for a week while traveling, many hours every day with no problems. On MacBook Pro 13 2017, it can receive video and power with a USB-C cable, no external power is required even the MacBook is working. Battery. I also tested a Dell laptop with a USB-C port and it doesn't deliver enough power, I had to use at least a 30W power adapter. I tried a 20W iPad charger and it wasn't enough. Conclusion: If you plan to use this monitor without an additional power adapter, make sure your laptop has enough power through its USB-C/Thunderbolt port.
