WiMiUS K3 vs WiMiUS S4 (Upgrade) Review: Pros and Cons

Finding the right projector to support your business needs or only for home entertainment is a bit tricky. There are many options available in the market, which brings many exciting features. If you’re interested in getting one from WiMiUS, check the comparison of WiMiUS K3 vs. WiMiUS S4 here.

WiMiUS K3 Review


This projector comes in a classic yet sophisticated design that reflects simplicity in its first impression. The combination of white and black colors covering its body feels just right.

You can quickly notice the WiMiUS brand on the front part. The lens itself looks extremely convincing.

WiMiUS K3 Features

WiMiUS makes a very significant innovation by creating this WiFi projector. It means you can just easily mirror the content you want through WiFi. No wire, no hassle.

You only need to be sure that your smartphone’s physical distance and the projector are within two meters.

Another notable feature is the native 1920 x 1080 display resolutions that make your screening experience is enjoyable. On top of that, it also comes with 7.500 Lumens that claim as 30% brighter than the other 7.000 Lumens projector.

To get you into a more optimum usage, WiMiUS K3 allows you to project flexibly. You can start from a distance of 1.5 meters up to 7 meters. However, the most recommended one is 3 meters.

Indeed, a great projector should have excellent audio too. In this case, WiMiUS equipped this device with reliable 10Watt dual speakers with SRS HiFi sound. The audio is loud, stereo, and as crisp as the visual.

Interestingly, it does leverage the Germany stable LED that claims to have a 100.000 hours lifespan.

WiMiUS K3 Pros and Cons

  • LED is less harmful to the eyes
  • Portable and lightweight
  • Low fan noise
  • Smooth video transmission
  • Manual keystone correction
  • Unfriendly for business or class teaching
  • Doesn’t have BlueTooth

WiMiUS S4 Review


It is a projector with an exceptional design, even becoming too unique as it looks like a half-moon. Its round rear part brings out eccentricity that is rarely happening in such a device.

It comes in a single color only: true white. On the top part, you will find the buttons to navigate the projector.

WiMiUS S4 Features

The most remarkable feature of the WiMiUS S4 is that it supports Bluetooth 5.0, the newest Bluetooth generation. Hence, you can easily connect your Bluetooth earbuds, AirPods, headsets, and more to get the entertainment on your hand.

WiMiUS doesn’t take this device lightly as it injects 1920 x 1080 display resolutions along with 7020 Luminous Flux. Enjoy the sharp images in full HD and a real theater-like experience.

It also has a built-in reliable HiFi stereo speaker that is loud, clear, and powerful.

If you love to enjoy 4K videos, then it’s possible to mirror it using this projection. Just connect it with your smartphone, tablet, or laptop. There’s no lagging issue so far reported.

Just like the other projector in common, it has a keystone correction feature. However, it would be best if you did it manually here, with a maximum correction of 15 degrees. Indeed, this can be a downside despite how impressive the rest of the features are.

If you’re aware enough that a device can get hot when in usage for a long time, you shouldn’t worry about WiMiUS projector S4. It has a decent cooling system that adopts a SmartEco principle.

Which is Better, WiMiUS K3 or WiMiUS S4?

However, each one has its notable features: WiMiUS K3 with its WiFi and WiMiUS S4 with its BlueTooth. There’s no winner in here as you can pick up from what you’re most comfortable with.
