In the world of tech gadgets, smartphone projectors in a pen are a unique and exciting new product. Who doesn’t love the idea of being able to project a video or presentation from your phone onto a wall or screen? It’s a great way to share content with others, or just enjoy some media with a larger screen. But not all smartphone projectors are created equal. In this review, we’ll take a look at two of the best models on the market: the PicoGenie M400 and the Shouder Pen Pico Projector.

When it comes to size and portability, the PicoGenie M400 takes the cake. This palm-sized projector is incredibly lightweight and can fit in your pocket. The M400 also features an LED lamp that provides up to 20,000 hours of lamp life, so you won’t have to worry about replacing it often. It also offers a 1080p resolution, and up to 120 inches of projection size. Plus, it’s compatible with a variety of devices including iPhone, iPad, and Android.

The Shouder Pen Pico Projector is a bit bigger than the M400, but it offers a few more features. It has a brighter lamp (100 lumens) for better image quality, and a longer battery life (up to 2 hours). It also offers a higher resolution (1920×1080), and a wider range of projection sizes (up to 180 inches). On the other hand, the Shouder Pen only works with Android devices, so if you’re an iPhone user, you’ll have to look elsewhere.

When it comes to price, the PicoGenie M400 is the clear winner. It’s currently available on Amazon for $99.99, while the Shouder Pen is $129.99. Both models come with all the necessary cables and accessories, so you won’t have to buy anything extra.

In conclusion, both the PicoGenie M400 and the Shouder Pen Pico Projector offer their own unique advantages. The M400 is smaller and more affordable, but the Shouder Pen has a brighter lamp and a higher resolution. If you’re looking for a portable, easy-to-use projector, either of these models will do the job.
