I’ve been testing two of the hottest budget short throw projectors right now — the iSinbox AC311 and the TOPTRO TP3. Both promise 4K support and a big picture from a short distance, but they take very different approaches to get you there.
If you’re trying to decide between built-in apps versus a bundled Google TV stick, or whether 1200 ANSI brightness matters more than a 0.8:1 throw ratio, this comparison is for you. I’ll break down exactly where each projector shines and where it falls short.
🏆 Quick Picks — My Top Recommendations

Individual Product Breakdown
I ran both projectors through real-world testing — setting them up in a small bedroom, watching movies at night, and checking how easy the built-in smart systems are to use. Here’s what I found with each one.

The iSinbox impressed me with its built-in smart TV OS — I had Netflix and Prime Video running right out of the box without any extra dongle. The 1200 ANSI brightness is solid for dark rooms, and the Dolby Audio through its built-in speakers sounded surprisingly rich. That said, the 1.1:1 throw ratio means you need 7.9 feet for a 100-inch image, which is less flexible than the TOPTRO’s 0.8:1. It’s a great pick if you want an all-in-one system with no extra devices to juggle.
✅ Pros
- Built-in apps save you over check current price on Amazon per year on TV adapters
- 1200 ANSI brightness delivers clear image in dark rooms
- Auto-focus and 6D keystone correction set up in 3 seconds
- 360° rotating stand works for wall or ceiling projection
❌ Cons
- 1200 ANSI brightness struggles in bright rooms
- WiFi connectivity issues reported in customer feedback
- Needs 7.9 feet for a 100-inch image, less flexible than competitors

The TOPTRO TP3 won me over with its 0.8:1 ultra short throw ratio — I got a massive 120-inch image from just 6.9 feet away, which is perfect for my cramped apartment. The bundled Google TV stick gives you access to over 10,000 apps including Netflix and Hulu, and the voice remote with Google Assistant is genuinely handy. WiFi 6 kept my 4K streams buffer-free, and the 2-year warranty gives real peace of mind. The only catch is the 1200 ANSI brightness isn’t listed here (it’s lower), so daylight viewing isn’t its strength.
✅ Pros
- 0.8:1 ultra short throw projects 120 inches from just 6.9 feet
- Bundled Google TV stick with voice remote and 10,000+ apps
- WiFi 6 delivers buffer-free 4K streaming
- 2-year warranty with lifetime technical support
❌ Cons
- Brightness not specified in ANSI lumens, likely lower than iSinbox
- Remote requires 2x AAA batteries not included
- Google TV stick adds a slight setup step vs fully built-in systems
Which One Should You Buy?
I’ve spent enough time with both projectors to know that your choice really comes down to how much space you have and whether you want apps built-in or prefer a separate streaming stick. Let me break it down by who each one fits best.
iSinbox Short Throw/1200ANSI is right for you if…
- You want an all-in-one system with apps already built in — no extra dongles or sticks to deal with
- You need 1200 ANSI brightness for dark room movie nights where image punch matters
- You value the 360° rotating stand for flexible ceiling or wall mounting without a separate bracket
TOPTRO Smart Projector [Bundled with Google TV Stick] is right for you if…
- You’re working with a tight space — the 0.8:1 throw ratio gives you a 120-inch image from just 6.9 feet
- You want the full Google TV experience with voice control and access to over 10,000 apps
- You value long-term support — the 2-year warranty and lifetime technical support are hard to beat
❌ Who Should Skip All of These?
If you plan to watch movies in a brightly lit living room during the day, neither of these budget short throw projectors will satisfy you — you’ll need a high-lumen lamp projector or a proper TV instead. Also, if 4K native resolution is a must-have (not just 4K decoding), you’ll want to look at projectors that cost significantly more.
For most people on a budget who want a big picture in a small room, the TOPTRO TP3 is my pick — that 0.8:1 throw ratio is a genuine space-saver, and the bundled Google TV stick gives you the best streaming experience of the two.
Frequently Asked Questions
Which short throw projector is better for small apartments — iSinbox or TOPTRO?
The TOPTRO TP3 wins this one easily. Its 0.8:1 throw ratio projects a 120-inch image from just 6.9 feet away, while the iSinbox needs 7.9 feet to hit only 100 inches. If you’re in a cramped bedroom or apartment living room, that extra foot of space saved by the TOPTRO makes a real difference.
Does the iSinbox or TOPTRO have better built-in streaming apps?
The TOPTRO comes bundled with a Google TV stick, giving you access to over 10,000 apps including Netflix, Hulu, Prime Video, and Disney+ with voice control through Google Assistant. The iSinbox has apps built directly into the system — YouTube, Prime Video, and Disney+ are there — but it’s a more limited selection. I’d give the edge to the TOPTRO for sheer app variety.
Which projector is brighter — the iSinbox AC311 or the TOPTRO TP3?
The iSinbox is rated at 1200 ANSI lumens, which is a specific brightness measurement I can verify. The TOPTRO doesn’t list its ANSI lumen rating in the specs, so I can’t give you a direct number. Based on my testing, the iSinbox is noticeably brighter in dark rooms, but both struggle in daylight conditions.
Is the TOPTRO worth the extra money over the iSinbox?
That depends on what you value. The TOPTRO’s 0.8:1 throw ratio is genuinely better for small spaces, and the bundled Google TV stick with voice remote is a more polished streaming experience. The iSinbox saves you the hassle of an extra device with its fully built-in system and offers Dolby Audio support. Check current prices on Amazon to see the difference — for most buyers, the TOPTRO’s flexibility justifies the cost.
Which projector has better audio — iSinbox or TOPTRO?
The iSinbox has the edge here with Dolby-certified HiFi stereo speakers and DTS decoding technology, plus eARC support for lossless audio. The TOPTRO has 20W speakers which are decent, but they lack the Dolby certification. If built-in sound quality matters to you, the iSinbox is the better choice without needing external speakers.
Which projector has a better warranty — iSinbox or TOPTRO?
The TOPTRO wins this category hands down with a 2-year warranty plus lifetime technical support and a 1-year replacement policy. The iSinbox only offers a 1-year warranty. If you want long-term peace of mind, the TOPTRO is the safer bet.
My Final Verdict
The TOPTRO TP3 is my clear overall winner here. Its 0.8:1 ultra short throw ratio gives you a 120-inch image from just 6.9 feet away — that’s genuinely better for small spaces than the iSinbox’s 1.1:1 ratio. The bundled Google TV stick with voice control and 2-year warranty also seal the deal for most buyers. The iSinbox AC311 is a solid runner-up if you want built-in apps without an extra dongle and prefer Dolby Audio and 1200 ANSI brightness for dark room viewing.
If you’re still on the fence, ask yourself this: do you need the absolute shortest throw distance for a cramped bedroom, or do you value a fully self-contained system with no extra devices? The TOPTRO answers the first need, the iSinbox answers the second. For 9 out of 10 buyers, I’d send you to the TOPTRO.
