Using a second monitor could quickly improve your productivity because you can practically view double the content. Having two windows open simultaneously lets you take info from one screen and use it on another; this is something that has to be experienced to be believed. Still, it works most of the time for people doing information-intensive tasks such as writing a paper, studying, or other work-related activities. That said, one of the difficulties of using a second monitor is figuring out which one you need and if you’re using a desktop computer. You may think you need another monitor of the same type you’re already using. That’s not entirely true.

Instead, you may want to look into using a portable monitor as these are far more versatile than stationary monitors that always require a power source to work. In his review, we’re taking a look at a somewhat higher-tier INNOCN portable monitor that has a 15.6-inch screen size, along with a 4K resolution display. This is not a low-cost budget monitor, but it’s a good choice if you’re looking for the best when it comes to quality and portability from a monitor.

What’s in the Box

With most tech products, you’re almost always going to want to check what accessories come with the product, or if any at all, come with it. Thankfully, this INNOCN portable monitor comes with everything you need to start using it right out of the box. Included in the box is the monitor itself a cover that also acts as a stand, two USB-C cables with one being for charging and the other being for data transfer, a wall charger, and a mini HDMI cable.

So you don’t have to wonder what you’re missing to use the monitor, which is automatically a reason to get this monitor.

Ports on the Monitor and Compatibility

Using the monitor is very simple because the first thing you should know is that this INNOCN portable monitor has a built-in battery. So as long a the battery is charged up, you don’t have to worry about plugging a wall charger into the monitor to power it. That said, when it does come time to recharge the monitor or if you want to charge it while you use it and not have to worry about it running out of power, then you can use the included wall charger to do so.

The monitor has two USB-C ports and one HDMI cable to the right side, with the top USB-C port being the one used for display connectivity and the lower USB-C port being used for charging small devices such as smartphones if needed. Of course, you can either use the top USB-C port or the HDMI port for display, but it’s going to depend entirely on if your device is compatible with one or the other.

If you want to use the USB-C port for display, then the device you’re connecting it to should have a Thunderbolt USB-C port; if not, you’ll have to use the HDMI port.

Also, if you have a power bank, you can charge up the monitor that way, too, and forget about using a wall charger for recharging. A 5,000mAh built-in battery is one of the best parts of this portable monitor, and we consider it to be on par with its 4K resolution display.

Quality of the Display and Usage

This is one of the best quality portable monitors that you can purchase because, as we mentioned at the beginning of this review, it has a 3840 x 2160 resolution, and yes, that means you are getting a 15.6 inch 4K display here. With such a high resolution on a relatively small display, the quality you’re getting is the best that you can get, and even think that it may be too much because when it comes to smaller displays, the resolution doesn’t matter as much. The difference between higher or lower resolution is less recognizable.

Of course, if you’re searching for the best display possible when it comes to a portable monitor, then this INNOCN PU15-PRE monitor is a good choice. The monitor can be used with nearly any device that uses a display, including smartphones, gaming consoles, tablets, and many others. You can use this INNOCN monitor to play PlayStation 5 or Xbox Series X videogames at 4K, as these consoles can play games at 4K.

This monitor has no compromise on quality and usability, which is easily one of the best parts.

Other than the monitors’ ports, this INNOCN monitor has two speaker grills on either side; it also has volume buttons and a power button at the top of the monitor. The power button can be used to turn the unit off and on; it can also be used to pop up the monitor’s settings menu that lets you adjust various display settings.

Build Quality and the Cover Stand

The build quality of this INNOCN is excellent, and if you’re wondering why the price is quite steep, well, that’s mainly due to the high-resolution display and because the build quality of that monitor is top tier. The monitor chassis is made of Aluminum, so it gives the monitor good structure and good weight; this does not feel like a cheap product, and this could quickly be sold as an Apple product, and there would be no question that it’s on Apple quality level.

The cover stand that comes with the monitor is pretty good, and when you’re not using the monitor, you can use it to cover the entirety of the monitor. When using the monitor, you have to fold the cover to the back, and it stands up the display. The cover gives the monitor a good viewing angle, but you can also use your stand.
