PONKLOIE 13.3″ Portable Monitor Laptop Screen Extender Review
The PONKLOIE 13.3-inch is a budget second screen with a 1366x768 panel at 300 nits, built-in speakers, one-cable USB-C or mini HDMI, and every cable plus the power adapter in the box. This review covers the HD resolution, the size, the connections, the missing stand, and who it suits.
PONKLOIE’s 13.3-inch portable monitor is a small, cheap second screen: a 1366×768 panel at 60Hz with a 3ms response time, 300 nits, a 1000:1 contrast ratio and a 178-degree viewing angle, in a body 10 mm thick that weighs 1.54 lb. It connects over USB-C or mini HDMI with the cables and a power adapter in the box, has built-in speakers and a headphone jack, and runs on laptops, phones, the Switch, PS4, PS5 and Xbox with nothing to install. It replaces the 11.6-inch PONKLOIE this page used to cover, which Amazon now lists as unavailable, and it is the same idea in a slightly larger frame: one extra screen for one task, not a workspace.
Read the resolution before the price. Amazon’s field calls the panel FHD, but the figures underneath it say 1366×768, which is HD, not Full HD, and the 13.3-inch size sits on a picker with 14, 16 and 17.3-inch options that are different panels with different shapes. This review covers the 13.3-inch model only.

Display Performance
1366×768 on 13.3 inches is about 118 pixels per inch, less than the 141 of a 15.6-inch 1080P panel and less than the 135 the old 11.6-inch model managed with the same pixel count. Text is readable at arm’s length and a single window fits without scaling, but fine text is soft next to a laptop screen and there is no room for two windows side by side. That is the whole nature of this monitor: one application at a time. Amazon’s field labels it FHD, and it is not; 1366×768 is the HD panel found in budget laptops.
The rest of the panel figures are ordinary in a good way. 300 nits is 50 more than the old model and enough for an office or a window seat, 1000:1 is the normal contrast for this class, and 178 degrees means the picture holds when the screen sits at an angle beside the laptop. The panel type is given only as LCD; a 178-degree figure usually means IPS, but PONKLOIE does not say so. The finish is glossy, which gives colour a little more punch in a dim room and reflects lamps and windows in a bright one; the old 11.6-inch model was matte.
Colour coverage is unknown. Amazon’s gamut field reads “75” with no unit, which may be 75 percent of sRGB and may be nothing, and PONKLOIE’s bullets give no figure at all. Treat it as a screen for documents, calls and video rather than colour work. FreeSync and flicker-free appear in Amazon’s feature fields, not in PONKLOIE’s text; the 3ms response time keeps scrolling and casual games clean at 60Hz.
The 13.3-Inch Size
13.3 inches is the size of a small laptop screen, and that is how to think of it: a second laptop-sized panel that sits beside the first. It is not a multi-window display. What it does well is take one job off the main screen: the video call while you take notes, the reference document while you write, the chat window while the spreadsheet fills the laptop, the lecture while the textbook is open. At 310 by 196 mm it fits a cafe table or a hotel desk where a 15.6-inch monitor would not, though it is two inches wider than the 11.6-inch model it replaces.
Design and Portability
The body is 10 mm thick and weighs 1.54 lb, a little more than the old 11.6-inch model at 1.42 lb and still among the lighter portable monitors. PONKLOIE calls the build sturdy and says nothing about the material. The listing also says nothing about a stand: the old model shipped a separate folding stand, and this one lists none in the box and none in the bullets, only a wall-mount option in Amazon’s fields with no VESA pattern. Ask the seller how the monitor stands up before you buy, because the box contents as listed do not include anything that holds it.
Connectivity
| Port | Count | Function |
|---|---|---|
| USB-C | 2 | Picture and power on one cable from a laptop or phone with USB-C video; power input when using HDMI |
| Mini HDMI | 1 | Picture from consoles and HDMI laptops, through the included USB-C to mini HDMI cable |
| 3.5mm Audio | 1 | Headphones |
One USB-C cable does everything on a laptop or a phone whose port carries video, with no driver on any system. Consoles connect through the mini HDMI input, and here the box is better than the old model’s: PONKLOIE lists a USB-C to mini HDMI cable, a second adapter cable, a USB-C charging cable and a power adapter, so a Switch, PS5 or Xbox setup needs nothing else bought. Amazon’s field counts two USB 3.0 ports; PONKLOIE names them only as USB-C. For what a USB-C port has to support, see our USB-C portable monitor guide.
Audio
Speakers are built in, with no output figure given, and a 3.5mm jack takes headphones. Expect enough for a call or a video and no more; the old model’s dual speakers were the same class.
What’s in the Box
| Item | Quantity |
|---|---|
| 13.3″ Portable Monitor | 1 |
| Power Adapter | 1 |
| USB-C Charging Cable | 1 |
| USB-C to Mini HDMI Cable | 1 |
| USB-C to Mini HDMI Adapter Cable | 1 |
| User Guide | 1 |
Both connection routes and the power are covered on day one, which the 11.6-inch model did not manage. No stand or cover is listed.
Potential Drawbacks to Consider
| Consideration | Detail |
|---|---|
| 1366 x 768 | HD, not Full HD, whatever Amazon’s field says. 118 ppi is soft next to a laptop screen. |
| No Stand Listed | Nothing in the box or the bullets holds the monitor up; the old model shipped a stand. |
| Glossy Finish | Reflects lamps and windows; the old model was matte. |
| Colour Gamut Unknown | Amazon’s “75” has no unit; PONKLOIE gives none. |
| Panel Type Not Named | LCD only; IPS is likely from the 178-degree figure but not stated. |
| Model Number Missing | The model field just reads PONKLOIE. |
| Reviews Shared Across Sizes | 491 ratings at 4.1 stars cover the 13.3, 14, 16 and 17.3-inch options. |
| One Window Only | The size and resolution suit a single task, not a workspace. |
Who This Monitor Is Best For
Anyone who wants the cheapest workable second screen for calls, chat and reference: 13.3 inches at 300 nits with speakers, a headphone jack, every cable and the adapter in the box, for less than most portable monitors’ cable kits. Park one application on it and keep the laptop for the work.
Students: the lecture on this screen, the notes on the laptop, at 1.54 lb in the same bag.
Casual console players who travel: mini HDMI with the cable included, 60Hz and 3ms, and a footprint that fits a hotel desk. A Switch, PS5 or Xbox plugs in with nothing else bought. For more portable gaming options, see our comparison pages.
Who Should Look Elsewhere
Users who need two windows or sharp text: 1366×768 fits one application. A 15.6-inch 1080P panel costs a little more and does far more.
Users who need accurate colour or a matte screen: the gamut is unstated and the finish is glossy. Our buying guide covers what to look for in both.
Anyone who needs the monitor to stand on its own out of the box: no stand is listed. Confirm with the seller, or budget for one.
Pros and Cons
| Pros | Cons |
|---|---|
| Light and thin: 1.54 lb, 10 mm | 1366 x 768, not the FHD Amazon’s field claims |
| 300 nits, 1000:1, 178 degrees | No stand listed in the box or the bullets |
| 3ms response, FreeSync and flicker-free listed | Glossy finish |
| USB-C one-cable use, mini HDMI for consoles | Colour gamut unstated; panel type not named |
| Every cable and the power adapter in the box | No model number; reviews shared across four sizes |
| Built-in speakers and a headphone jack | Room for one window only |
| 1-year warranty at a low price |
Final Verdict
The PONKLOIE 13.3-inch is a budget companion screen and it is honest about being one: HD resolution, one window at a time, and a price that most portable monitors cannot touch. Within that brief it is well equipped, with 300 nits, speakers, a headphone jack, one-cable USB-C, and a box that finally includes the HDMI cable and the power adapter the old 11.6-inch model left out.
Two things need an answer before buying. The listing names no stand, so ask the seller how the monitor stands up, and the glossy finish and unstated colour gamut make it a screen for calls, documents and casual games rather than anything colour-critical. For a second screen that travels light and does one job, it is a sensible buy; for anything more, spend the extra on a 15.6-inch 1080P panel across our comparison hub.
Frequently Asked Questions
Is it Full HD?
No. Amazon’s field says FHD, but the resolution fields say 1366×768, which is HD. On 13.3 inches that is about 118 pixels per inch: fine for a call, a document or a video, soft for small text.
Does it come with a stand?
The listing does not say. The box contents name the monitor, an adapter, three cables and a guide, and the only support mentioned is a wall mount with no VESA size. Ask the seller before ordering.
Does it work with a Nintendo Switch or PS5?
Yes, over mini HDMI, and the USB-C to mini HDMI cable is in the box, as is the power adapter the console cannot replace.
What does the “75” colour gamut mean?
Nothing certain. Amazon’s field gives the number without a unit and PONKLOIE gives no figure, so colour coverage is unknown. Assume it is below full sRGB.
How is this different from the 11.6-inch PONKLOIE?
Same 1366×768 resolution on a screen 1.7 inches larger, 300 nits instead of 250, a 3ms response instead of 2ms, a glossy finish instead of matte, and a box with the HDMI cable and adapter included. The 11.6-inch model shipped a stand; this one does not list one.
