When we wrote our Happrun H1 review, which led to its being crowned as one of our favorite budget options among low-cost projectors, we noted one major flaw: the projector maxed out at 1080p resolution. While that issue is not unique to the H1 alone, the company seeks to remedy that flaw with the newer Happrun 510G Projector with 4K support, Dolby sound, built-in streaming apps, and compatibility with game consoles and smartphones.
The Happrun 510G projector is among the newest budget-friendly models on the market, offering decent wireless connectivity and straightforward usability at a very reasonable price. While it isn’t as portable or as feature-packed as the Benq GS50, it still gets the job done for anyone looking for an affordable home entertainment solution without sacrificing much in terms of image quality and connectivity options.

Design & Build Quality
The Happrun 510G feels modern and thoughtfully constructed. The body uses a blend of smooth matte materials and a fabric-textured speaker grille, giving it an aesthetic similar to today’s lifestyle-focused electronics. Its compact size makes it ideal for small rooms, dorms, office presentations, or outdoor movie nights.
The projector features a centrally positioned lens surrounded by a protective bezel, with manual focus and keystone adjustment knobs placed conveniently toward the front or top, depending on your mounting preference. The ventilation system is designed to push heat away from the lamp while minimizing fan noise, and during extended sessions, the cooling seems well-managed. Users sensitive to noise may notice a light hum, but it remains quieter than many budget projectors in this price category.
The rear panel houses a versatile port selection, including: HDMI input, USB port for local media playback, AV input for older devices, audio out for external speaker connectivity, and a power port.
This array of ports ensures compatibility with laptops, gaming consoles, DVD players, TV boxes, and streaming sticks. The overall build may not feel premium like high-end projectors, but for its category, the Happrun 510G proves robust and portable.
Setup and Ease of Use
One of the biggest strengths of this projector is how quick and intuitive the setup process is. Out of the box, the Happrun 510G arrives nearly ready to use—after plugging it in, you just adjust the manual focus and keystone to achieve a sharp, rectangular image.
The keystone features vertical correction, helping compensate for slightly angled placements, though like most manual projectors, extreme angles may still cause distortion. For best results, the projector should sit roughly perpendicular to the projection surface.
Wireless connectivity—a major selling point—allows streaming content from smartphones, tablets, and laptops. The Wi-Fi mirroring supports both iOS and Android devices, making it ideal for casual sharing of videos, presentations, or streaming apps.
The user interface is simple, with easy-to-navigate menus and responsive controls. Even first-time projector owners will find it painless to get started.
The Happrun 510G Projector comes with Google TV, which gives access to all the apps you could ever need for home entertainment.
Image Quality
The heart of any projector is its visual output, and the Happrun 510G delivers surprisingly good performance for its class. The 510G projector offers enough brightness for evening use or dimly lit environments. Although not designed for fully lit rooms, it stands strong in the video-watching sweet spot—indoors with curtains drawn or outdoors after sunset.
Colors appear lively, especially when projecting animated content, nature documentaries, or colorful gaming scenes. The image looks most vibrant when projected onto a proper screen, but even a clean wall produces enjoyable results.
While 1080p native, the projector supports up to 4K resolution, and the resulting image appears decent for casual movie viewing or gaming. Text is reasonably legible, though users watching subtitles should aim for a well-focused screen and a closer viewing distance.
The contrast ratio produces acceptable depth, with blacks leaning toward dark grey, normal for budget LED projectors. Still, shadow details in movies remain recognizable, and bright scenes are punchy enough to feel immersive.
The Happrun 510G is capable of projecting a screen up to around 200 inches, though the best performance sits between 60″ and 300″. At larger sizes, brightness and sharpness naturally diminish, but for typical home use, the projector performs consistently within optimal ranges.
Gamers will appreciate the low input lag for casual console gaming. Titles on PlayStation, Xbox, or Nintendo Switch appear responsive enough for immersive gaming. Competitive FPS gamers may notice slight latency, which is typical for LED projectors, but for everyday gaming fun, the Happrun 510G performs admirably.
Wireless Connectivity & Compatibility
The Happrun 510G runs Google TV built-in and includes reliable wireless mirroring for smartphones. Users can cast: YouTube videos, photos, downloaded media, and some streaming service clips. Unlike its predecessor, the Happrun 510G projector is now Google TV certified, meaning you have access to all the streaming apps you could ever need without the need for an external streaming device to access content from, let’s say, YouTube, Netflix, Prime Video, and other platforms.
The Wi-Fi setup process is straightforward, and once paired, the connection remains stable for most streaming needs. Occasional lag is possible with very large files or heavy network congestion, but this is expected with wireless projection in general.
Happrun 510G Projector Review: Bottom line
The Happrun 510G projector is a strong competitor in the budget projector space, offering a compelling blend of affordability, portability, and visual performance. With Google TV-certified access, wireless functionality, solid brightness, decent sharpness, built-in apps, and an easy setup process, it delivers an experience that newcomers and casual users will appreciate.
While not perfect—particularly in challenging lighting conditions or for users seeking professional-grade picture depth—the projector succeeds remarkably well in its goal: delivering a fun, big-screen experience at a price that feels more than fair.
Whether you’re planning family movie nights, dorm gaming sessions, or simple presentations, the Happrun 510G Projector offers excellent value and an enjoyable display experience. It’s a worthy purchase for anyone looking to expand their entertainment possibilities without stretching their budget.
