The budget IPS portable monitor is now on sale for $139 USD to be one of the least expensive and lightest 15.6-inch models available. Display quality is decent with a fair list of cut corners considering the low price.

The 15.6-inch Lepow C2 portable monitor is now on sale through the official manufacturer online store for $139 USD after applying the coupon code '30lepow101' at checkout. The deal is expected to last until September 15 or until supplies last. The manufacturer has sent us a test unit for our honest impressions.

There are two noteworthy advantages about the C2. The first is its low weight of just 681 g compared to other portable monitors like the AirTab which is nearly a whole kilogram. If you intend to carry the monitor around with you during trips, then the C2 is one of the lighter 15.6-inch monitors you can find.

The second advantage relates to its large and rigid stand for propping up the display. When compared to the folding folio stands of other portable monitors like the C-Force CF011SAuzai ME16Z01, or aforementioned AirTab, the stand on the C2 is much more reliable at more angles and less likely to fall over.

Other pluses include integrated support for USB-C, mini-HDMI, and mini-DisplayPort for a total of three video input options.

There are several disadvantages to keep in mind. Firstly, the C2 is at heart a budget portable monitor and so colors are limited to just 60 percent of sRGB. If accurate colors are required, then you may want to consider pricier portable monitors like the Innocn 15K1F. Secondly, the display is not bright enough for comfortable outdoor viewing. The C2 works best indoors such as in airports or office spaces where space may be tight.

Thirdly, the C2 does not ship with any protective folio cases unlike on many other portable monitors. You'll have to be careful to not damage the screen when traveling as a result.

Another annoying aspect of the C2 is that it utilizes mini-HDMI instead of full-size HDMI. Mini-HDMI cables are much less ubiquitous and so users may need to carry around a mini-HDMI to full-size adapter or cable with them at all times. Fortunately, the retail box includes a compatible cable.
