I purchased this micro PC to use as a portable HTPC during travel. On paper, it's perfect for this use case. In practice, the manufacturers decision to use micro USB as the power supply prevents the PC from ever performing well.Micro USB cannot provide enough power to run the Celeron CPU. The manufacturer provides a power adapter which outputs far beyond the micro USB spec, but even that isn't enough. The PC can't keep up with 4k video playback. The only way to get 60fps video playback is to drop the resolution to 1080p.Pay attention to the other reviewers who mention the power limitations, and look up youtube video reviews on the same subject. Micro PCs in the same price range or lower, with the same CPU, get %50 better performance when supplied with full power. I recommend finding a different micro PC with proper power input design.
