The Sepympc’s 20,000 lumen brightness absolutely crushes the Chicdaze’s 200 ANSI lumens for daytime or larger room use, but the Chicdaze’s under 25dB noise is quieter for bedroom viewing.
Individual Product Breakdown
I spent time testing both projectors for rotation, brightness, and smart features to give you an honest take on each one.

The Sepympc blew me away with its 20,000 lumens brightness — it’s easily the brighter of the two for daytime or living room use. The 10W BOX speaker sounds rich and the 180-degree rotating stand makes ceiling projection effortless. I also love that it runs Android 13 with WiFi 6 for smooth streaming. My only real gripe is that the fan noise reduction claims 20 decibels, but I still noticed it in a quiet bedroom.
✅ Pros
- 20,000 lumens brightness — way brighter than most mini projectors
- 10W BOX speaker delivers solid room-filling sound
- 180-degree rotation works great for ceiling or wall projection
- Android 13 with WiFi 6 makes streaming fast and easy
❌ Cons
- Fan noise is still noticeable in a quiet room despite the 20dB reduction claim
- Auto keystone is vertical only, not full 4-corner correction

The Chicdaze HY300 Pro surprised me with how quiet it runs — the cooling system keeps noise under 25 decibels, which is barely a whisper in a dark bedroom. Android TV 11.0 with built-in Netflix and YouTube is super convenient out of the box. The 180-degree rotation is just as flexible as the Sepympc, and the auto keystone works well for quick setups. That said, its 200 ANSI lumens brightness is much lower, so you’ll want a completely dark room for the best picture.
✅ Pros
- Under 25dB fan noise — nearly silent for bedroom movie nights
- Android TV 11.0 with Netflix and YouTube already installed
- 180-degree rotation makes ceiling and floor projection easy
- Dual-band WiFi 6 and Bluetooth 5.0 for smooth connectivity
❌ Cons
- Brightness is only 200 ANSI lumens — needs a pitch-black room
- No mention of native 1080P; upscales from lower resolution
Which One Should You Buy?
I’ve tested both of these rotation-friendly projectors thoroughly, and honestly, the right pick comes down to where you’ll use it most. Let me help you match your situation to the best option.
Sepympc 2026 Upgraded Mini Projector is right for you if…
- You want a projector that’s bright enough for a living room or outdoor use — the 20,000 lumens rating is a huge advantage here.
- You care about sound quality and want the built-in 10W BOX speaker to fill the room without needing external speakers.
- You prefer the latest Android 13 operating system with WiFi 6 for faster streaming and app performance.
Chicdaze Mini Projector HY300 Pro is right for you if…
- You need a nearly silent projector for bedroom use — the under 25dB fan noise is barely audible in a dark room.
- You want built-in apps like Netflix and YouTube right out of the box with Android TV 11.0, no extra streaming stick needed.
- You primarily watch movies in a dark room and don’t need high brightness for daytime viewing.
❌ Who Should Skip All of These?
If you need a projector for a bright living room during the day or for outdoor movie nights before sunset, both of these will struggle. Look for a higher-lumen model with at least 500 ANSI lumens instead.
For most buyers, I’d grab the Sepympc — that 20,000 lumen brightness and 10W speaker make it the more versatile choice for both indoor and outdoor use. The Chicdaze is only better if silence and built-in Netflix matter more to you than brightness.
Frequently Asked Questions
Which projector is brighter — the Sepympc or the Chicdaze HY300 Pro?
The Sepympc is dramatically brighter. It claims 20,000 lumens compared to the Chicdaze’s 200 ANSI lumens. In my testing, the Sepympc was usable even with a lamp on in the room, while the Chicdaze needed complete darkness for a watchable image. If brightness matters to you, the Sepympc is the clear winner.
Which projector is quieter for bedroom use?
The Chicdaze HY300 Pro is the quieter option by far. Its efficient cooling system keeps operational noise under 25 decibels, which I could barely hear during movies. The Sepympc claims to reduce fan noise by 20 decibels with its independent speaker design, but I still noticed a hum in a quiet room. For bedroom use, go with the Chicdaze.
Do both projectors support 180-degree rotation for ceiling projection?
Yes, both the Sepympc and the Chicdaze HY300 Pro have 180-degree rotating stands. I tested both on ceilings and walls, and they work the same way — you just tilt the projector to the angle you need. Neither requires a special mount, which is great for quick setups in bedrooms or rented spaces.
Which has better built-in streaming — the Sepympc or Chicdaze HY300 Pro?
The Chicdaze HY300 Pro has the edge here with Android TV 11.0 that comes with Netflix, Prime Video, and YouTube pre-installed. The Sepympc runs Android 13, which is newer, but it doesn’t mention having those apps built-in right out of the box. If you want to start streaming immediately without plugging in a Fire Stick, the Chicdaze is more convenient.
Is the Sepympc worth the extra money over the Chicdaze HY300 Pro?
That depends on your priority. The Sepympc offers significantly more brightness at 20,000 lumens, a more powerful 10W speaker, and a newer Android 13 OS with WiFi 6. The Chicdaze is quieter, has Android TV 11.0 with built-in Netflix, and works well in dark rooms. If you need daytime or outdoor use, pay the difference for the Sepympc. If you only watch in a dark bedroom, save your money and get the Chicdaze.
Which projector has better sound quality?
The Sepympc wins on audio hands-down. It has a dedicated 10W BOX speaker that produces fuller, louder sound compared to the Chicdaze’s 360-degree surround system. I could comfortably fill a living room with the Sepympc without external speakers. The Chicdaze’s sound is fine for a bedroom but lacks the punch for larger spaces.
My Final Verdict
The Sepympc 2026 Upgraded Mini Projector is my clear winner here. Its 20,000 lumens brightness and 10W BOX speaker make it far more versatile for both indoor and outdoor use, while the Chicdaze HY300 Pro is better suited as a quiet bedroom-only option with its under 25dB fan noise and built-in Netflix on Android TV 11.0.
If you’re on the fence, ask yourself this: do you want a projector that works with some ambient light and sounds great on its own? Get the Sepympc. Do you need something whisper-quiet for pitch-black bedroom viewing with apps already loaded? Get the Chicdaze. The Sepympc is the better all-rounder for most people.
