The HAPPRUN 1500 ANSI and WiMiUS P62 Pro both target the budget-friendly smart projector market, delivering native 1080p resolution with 4K input support, but diverge significantly in their core strengths and value propositions. The most striking difference lies in brightness, with the HAPPRUN boasting 1500 ANSI lumens—nearly double the WiMiUS's 800 ANSI lumens. In real-world use, this means the HAPPRUN will produce a much more vibrant and watchable image in rooms with ambient light, or when projecting larger images outdoors after dusk, whereas the WiMiUS will require a darker environment to truly shine. For daytime viewing or moderately lit indoor spaces, the WiMiUS will struggle to deliver satisfying contrast and color depth compared to its brighter competitor.

Beyond brightness, the smart operating system is a key differentiator. The HAPPRUN features "Official Licensed Google TV," providing a comprehensive and familiar smart TV experience with access to a vast ecosystem of apps, voice control via Google Assistant, and seamless integration with other Google services. This elevates its utility beyond mere projection. The WiMiUS, while featuring "Built-in Official Apps" like YouTube and Prime Video, offers a more limited smart interface, suitable for those who primarily use these specific services but less versatile for broader streaming needs. The HAPPRUN’s inclusion of WiFi 6 also suggests superior wireless performance for streaming and screen mirroring.

Audio performance presents an interesting trade-off. The WiMiUS explicitly highlights "Dolby Audio with Dual Speaker" and 20W speakers, suggesting a more robust built-in sound solution than the HAPPRUN, which notes its "Built-in speakers may lack full audio range." For users who won't always pair with external speakers, the WiMiUS might offer a more satisfying auditory experience out of the box. The WiMiUS also includes HDR support, which is not specified for the HAPPRUN, potentially offering better dynamic range. However, the HAPPRUN’s superior brightness and Google TV integration command a higher price point of $389.99 compared to the WiMiUS's more accessible $299.99. Buyers must weigh whether the extra brightness and premium smart OS of the HAPPRUN justify the nearly $90 price difference, or if the WiMiUS's cost-effectiveness, HDR support, and potentially better integrated sound are more appealing for casual, darker-room viewing. Both offer auto focus and full keystone correction for easy setup, a welcome feature for portability and varied placement.
