The most reliable specification on a sub-$100 projector listing is the review count. Not the lumens, which nobody has certified; not the contrast ratio, which is a number somebody chose; not the resolution, which is often the input resolution wearing the native resolution’s clothes. The review count is the one figure on the page that the seller cannot write.
By that measure the field below is unusually well documented. One of these machines has 22,041 ratings. Another has 13,749. Two have fewer than a hundred, and that is worth knowing before you spend anything. Every price here was checked against the live listing on 25 August 2026, and every machine here is a single-panel LCD, because under $100 nothing else exists.
The cheapest thing here by a wide margin, and it has been getting cheaper. Our daily price log has it at $49.99 through the first week of August, $42.07 on 16 August, $41.99 on 24 August and $37.77 today. That is a quarter off the price in three weeks with no change to the product.
It is a 720p TFT LCD panel — native 1280 x 720, with 4K files accepted and downscaled — rated at 200 ANSI lumens with 1,500:1 contrast. The throw ratio is 0.8:1, which is short for the category and genuinely useful in a small room: a 100-inch image comes off a wall about 6 feet away instead of 8. Keystone is automatic vertically and manual horizontally, focus is manual, and the light engine is LED. Rating is 4.1 across 1,245.
The 4.1 is honest rather than alarming. At this price the complaints cluster on the same two things every time, which are that manual focus drifts if the projector gets bumped and that the picture washes out with any light in the room at all. Both are true, and both are true of everything else on this page. Specifications sit on the Magcubic HY300Pro product page.
Nothing else in this bracket comes close to that number, and it is years of accumulated buyers rather than a launch spike. The rating across all of them is 4.3, which for a projector this cheap is the single most persuasive fact in this guide.
The hardware is modest and the listing is honest about it: native 1280 x 720 on single-panel LCD with 1080p input accepted. TMY does not publish a brightness figure at all, which is either commendable restraint or an unflattering number left out, and we have no measurement to settle it. There is two-way Bluetooth, so it will send audio to a speaker and receive audio from a phone, and an 80-inch screen comes in the box.
The price has been drifting down: $89.99 on 10 August, $79.99 on 18 August, $69.98 today. Full details are on the TMY V08 product page, and we put it head to head with the list’s number-one seller in this comparison.
The one machine here with a native 1080p panel rather than 720p, which on a 100-inch wall is the difference you actually see. YGSKK states 300 ANSI lumens; there is no certification behind that figure, and 300 ANSI from a $74 single-panel LCD would be remarkable, so read it as the ceiling of a range.
Streaming apps are built in, there is dual-band Wi-Fi and Bluetooth, and it spent most of August as the number-one projector on Amazon’s best-seller list. Rating is 4.4 across 3,811 — the best combination of score and sample size on this page. Price has bounced modestly: $69.98 in late July, $75.99 for most of August, $73.99 today. More on the YGSKK product page.
Every single reading in our price log since 28 July has this machine at exactly $84.93. No promotions, no coupon theatre, no ranking-driven wobble. It reached number one on the best-seller list on 24 August without changing price to get there.
Native 1080p on single-panel LCD, rated at 250 ANSI lumens, claimed 10,000:1 contrast, LED light source quoted at 100,000 hours. Focus is manual and keystone is manual and vertical only, which is the trade for the resolution at this price. Rating 4.3 across 13,749, the second-largest sample in the guide.
It is the sensible default if you want 1080p, do not want to gamble on a small review base, and are prepared to spend thirty seconds getting the picture square by hand. We compared it directly against the Roku option below last week; specifications are on the HAPPRUN H1 product page.
Five cents more than the HAPPRUN and a completely different proposition. This one has Roku TV licensed and built in, which means Netflix, Prime Video, Disney+, Hulu, YouTube and Apple TV are real applications on first boot, plus Roku’s free channel wall, with no streaming stick, no second remote and no input switching.
The trade is the panel. It is 720p, rated at 150 ANSI lumens, the dimmest and lowest-resolution machine in this guide. In exchange you get a 270-degree rotating stand that will point the image at a ceiling, automatic keystone correction, Dolby Audio through two 2W drivers, and HDMI, USB and a 3.5mm output. Focus is manual.
Rating is 4.5, but across only 76 ratings — a young listing rather than a proven one. Price has been flat at $84.98 since it appeared on the best-seller list on 14 August. The Miroir product page has the numbers.
The most volatile listing in this guide by a distance. ELEPHAS arrived on the best-seller list on 20 August at $199.99 and is $99.99 today. At the old price it made no sense next to the Miroir; at the new one it is a reasonable purchase.
Same core hardware as the Miroir on paper — native 1280 x 720, 150 ANSI lumens, 1,000:1, licensed Roku TV, manual focus and keystone — with a better radio stack: dual-band Wi-Fi 6, Bluetooth 5.2 and official Apple AirPlay, so an iPhone or a Mac casts to it directly. It gives up the rotating stand and the automatic keystone. Rating is 4.5 across 82, and the full numbers are on the ELEPHAS product page. We set it against the machine one rung up in a separate comparison.
The reason it appears last rather than first is the price history. A listing that has moved a hundred dollars in five days can move again, and $99.99 is not a number to plan around.
None of these projectors works in a lit room. Every one of them is rated somewhere between 150 and 300 ANSI lumens, none of those figures has been through a testing house, and even taken at face value they are a tenth of what a living-room television puts out. A sub-$100 projector is a night-time device pointed at a wall, and every buyer who is disappointed by one was expecting daylight.
None of them focuses itself either, with the partial exception of the Magcubic’s vertical keystone. That is the clearest single dividing line in the market: automatic focus and automatic keystone start at around $130, and if you are going to move the projector regularly, that is the feature worth crossing the $100 line for. The Dangbei N2 mini at $179 is the cheapest machine we have tested where the whole setup — focus, keystone, licensed Netflix — happens without you touching a menu, and the middle of that range is mapped out in our under-$200 guide.
Within the hundred dollars itself, the choice comes down to what you are optimising. The largest verified body of owner experience is the TMY V08. The most stable price and the best resolution-per-dollar is the HAPPRUN H1. The only two that stream without a dongle are the Miroir and the ELEPHAS, and both pay for it in pixels.
