Review of the Lepow USB powered portable monitor

15.6-inch 1080p for little money. The 15.6-inch portable monitor with narrow, lightweight bezel has an attractive design with a high quality feel when it is held. The actual display, however, reflects the cheap price point.

Portable Monitor – Lepow 15.6 Inch Computer Display 1920×1080 Full HD

The Lepow is a cheap and portable 15.6-inch external monitor designed to be transported and used on the move. Its most notable features are the 2x USB Type-C ports for power and video, which means that the monitor will be compatible with most newer laptops and smartphones that are starting to rely almost entirely on USB Type-C.

The lightweight monitor can currently be found on  Amazon for $ 179.

Case

The chassis is firmer and stiffer than the Odake BladeX external monitor. However, it is not as inflexible as an   Apple iPad, probably because Lepow lacks Gorilla Glass’s edge-to-edge reinforcement.

Interestingly, the monitor weighs almost the same as the  Microsoft Surface Pro 6, although the latter offers a much smaller screen size.

Front: No connectivity
Behind: No connectivity
Right: USB Type-C video output port, volume / OSD control, Power / OSD button
Left: 3.5mm headphones, USB Type-C power port, Mini-HDMI

Connectivity

Port selection is limited, which means that unfortunately, you will have to rely on adapters. It is disappointing to see the mini-HDMI instead of the most common full-size HDMI since most users will only have full-size HDMI cables ready.

Only the left USB Type-C port closest to the mini-HDMI port can be used to power the monitor. Most USB Type-A ports can be used to power the monitor. The other USB Type-C port along the opposite edge of the monitor will accept video.

Accessories

Fortunately, the box includes all the cables you will need to start using the monitor.

  • Screen saver
  • Magnetic faux leather case
  • Mini-HDMI to full-size HDMI cable
  • USB Type-A to USB Type C power cable
  • USB Type C to USB Type C video cable
  • Screen wipe

Display

While the chassis is high quality, the real screen is a basic offer. Both the maximum brightness and the contrast, in particular, are below average to a measure of 193 nits and 259: 1, respectively. Combine this with a narrow range and you will get relatively muted colors and gray blacks. This is definitely not the monitor that should be used for video editing or for professional graphics work. 

However, for games, navigation and word processing, the quality of the visualization is sufficient. The additional real estate screen is invaluable and the response times are good enough for casual 3D games such as Rocket League or DOTA 2. The content on the screen is crisp despite the matte overlay.

The color space is narrow, with only 62% and 39% of the sRGB and AdobeRGB standards, respectively, indicating that it is a budget panel. In fact, the results are similar to the cheap 15.6-inch laptops like the  Lenovo IdeaPad 330s. The flagship ultraportable with high-end Sharp IGZO panels such as the  XPS 15 tends to cover sRGB in its entirety and more for deeper and more precise colors.

The display is poorly calibrated out of the box with an average grayscale and color deltaE values ​​of 7.6 and 6.66, respectively. Our calibration efforts improve both aspects significantly to obtain much more accurate colors. However, due to the limited range, colors will continue to be more inaccurate at higher saturation levels. Blue, in particular, is represented with much less precision than other primary or secondary colors.

We recommend applying our ICM profile above to get better monitor colors when connected to a Windows PC.

Emissions

Temperature

The surface temperatures are warmer near the lower-left corner and cooler near the opposite corner with a difference of almost 12 degrees C. The hot spot is near the USB Type-C port where the monitor receives its power. 

Speakers

Check the sound of the built-in speakers (sound, noise, bass, maximum volume, …) in different music/telephone genres, compare within the device category, special features (software),.

Note: How can external audio devices be connected? Test the sound interfaces when appropriate.

Pink Noise characteristic audio: next element of comparison (you have to upload .csv measurement)

Energy consumption

The monitor consumes an average of 2.9 W and 7 W when it is in the minimum and maximum brightness settings, respectively. A generic Type-C USB charger can power the screen as long as it emits at least 5V / 2A.

Verdict

In review: Portable Monitor Lepow Type C X0025I0D4P. 
Review unit provided by Lepow

The manufacturing quality of the Lepow portable monitor is excellent, especially considering the low entry price. It is light and small enough to carry with a laptop like any other tablet. The screen is good enough for casual navigation, data entry or light games, although we believe it could have been brighter and with a deeper contrast to enhance the viewing experience.

The most inconvenient aspect of the portable monitor is that it requires two different cables for use. Although all the cables you will need are included in the box, it is still a hassle to carry both a USB Type-C to Type-A cable and a mini HDMI cable. The monitor will have to continuously consume power from your laptop, which will inevitably reduce the battery life of your PC or MacBook. A Thunderbolt 3 port or internal battery pack would have reduced clutter by eliminating the need for two cables, as in the  4K Odake monitor.
