The catch
JMGO N3 Ultimate
At 6.95 kg, the body outweighs the X1.
Side by side
JMGO N3 Ultimate vs Nebula X1: X1 carries lighter, N3 reaches farther back
Quick verdict
The N3 Ultimate fits if your shelf sits farther back or four-way optical lens shift would fix your placement. The Nebula X1 fits if you care more about its 0.75 kg lower weight and built-in carry handle. Google TV and optical zoom come with both. Since the brightness claims follow different standards, do not convert them into a percentage lead.
Before you buy
Why, and what it costs you
For 120 inches, fourteen feet is a handy dividing line
From that distance, a 120-inch 16:9 picture takes a throw ratio of about 1.606. JMGO reaches it optically. X1 stops at 1.5, so it would need a larger image or a closer position.
Where this comes from
120 × 16 / √337 gives an image width of 104.589 in, and 14 × 12 / 104.589 = 1.606. JMGO's range of 0.88 to 1.7 includes 1.606. X1's range of 0.9 to 1.5 does not.
The catch
Nebula X1
How far back it can produce the same picture size is limited by its 1.5 maximum throw ratio.

In practice
Differences you will notice
For 120 inches, fourteen feet is a handy dividing line
From that distance, a 120-inch 16:9 picture takes a throw ratio of about 1.606. JMGO reaches it optically. X1 stops at 1.5, so it would need a larger image or a closer position.
How we worked this out
120 × 16 / √337 gives an image width of 104.589 in, and 14 × 12 / 104.589 = 1.606. JMGO's range of 0.88 to 1.7 includes 1.606. X1's range of 0.9 to 1.5 does not.
About 10.8% of the projector weight comes off with the X1
If the projector moves often, the X1 is worth considering for its 0.75 kg saving and retractable handle. It is still a 6.2 kg mains-powered device, so this is room-to-room carrying and not something pocketable or battery-operated.
How we worked this out
(6.95 - 6.2) / 6.95 × 100 = 10.8%, a difference of 0.75 kg. Nebula publishes its dimensions with the handle retracted and includes an AC power supply.
A 65.7% improvement claim is not supported by the brightness labels
You can divide 5,800 by 3,500 and get a number, but it mixes published ISO and ANSI ratings. Before saying JMGO is a particular percentage brighter, a buying decision needs comparable measurements in useful picture modes.
How we worked this out
JMGO's source gives 5,800 ISO lumens, and Nebula gives 3,500 ANSI lumens. These records contain no common-mode measurement and no validated conversion factor.

This checks hard limits only. Personal preferences are left out of the math.
JMGO N3 Ultimate
Works with your numbersFor a 120-inch 16:9 picture, the calculated lens range is about 7.67 to 14.82 ft. You entered 9.50 ft.

Measure distance from the lens to the screen. The math assumes a 16:9 picture and uses the verified throw range for each exact model.

Spec by spec
Where they really differ
| Spec | JMGO N3 Ultimate | Nebula X1 | In practice |
|---|---|---|---|
| Optical throw range | 0.88 to 1.7:1 | 0.9 to 1.5:1 | For the same image width, JMGO reaches slightly closer and much farther back. |
| 120-inch 16:9 lens distance | About 7.67 to 14.82 ft | About 7.84 to 13.07 ft | At this image size, a shelf 14 feet from the screen is inside JMGO's range and outside X1's. |
| Published projector weight | 6.95 kg | 6.2 kg | Before accessories go in the bag, the X1 is 0.75 kg lighter. |
| Brightness claim | 5,800 ISO lumens | 3,500 ANSI lumens | A reliable percentage comparison cannot be built on these figures alone, because the labels and test conditions differ. |
| Built-in speaker rating | 2 × 12.5 W | 2 × 15 W plus 2 × 5 W | The driver layout and the rated power are not the same on both. Neither number measures dialogue clarity or usable loudness. |
| Streaming platform | Google TV with Netflix | Google TV with Netflix | Both include a built-in streaming platform, with app availability and subscriptions still applying. |
Trade-offs
What each pick costs you
With JMGO N3 Ultimate
- A 5,800 ISO-lumen claim cannot be compared directly with the X1's ANSI rating.
With Nebula X1
- Even at 6.2 kg, the body still needs mains power and a safe space to carry it.
Change of plan
When the answer changes
A 120-inch screen means the lens has to be 14 feet away
Go with JMGO N3 Ultimate. That image is within JMGO's published optical range.
Both fit my room, and what matters most is weight when carrying
Go with Nebula X1. The X1 weighs 0.75 kg less and includes a retractable handle.
With the lens six feet away, I need 120 inches
Neither model fits. Neither minimum throw ratio is short enough for that setup.
Decision guide
How to decide
Take the N3 Ultimate when a shelf farther back or four-way optical lens shift is what your placement needs. Take the Nebula X1 when lower weight (0.75 kg) and a built-in carry handle count for more. Both come with Google TV and optical zoom. Their brightness claims rest on different standards, so they should not be turned into a percentage advantage.
Make sure the shelf really works
Both projectors have optical zoom, so image size can be adjusted without shrinking it digitally. The JMGO reaches farther toward a distant shelf. If your room already puts the lens ten feet from a 120-inch screen, both pass the basic distance calculation and other priorities can settle the purchase.
The gimbal and the lens do different jobs
Tilting the projector changes where it points, while optical lens shift moves the projected image without tilting the whole body. JMGO documents four-way lens shift, which is handy when the shelf is off-center. Before counting on it for a given offset, confirm how much adjustment is allowed.
Do not oversell the portability or the brightness numbers
The X1 is lighter, but neither one is a tiny travel projector, and neither fixes the question of where to plug in. Brightness labels deserve caution too. Because we have not measured the two in matching modes, the verdict rests on verified placement and carrying differences. It does not invent a brightness ratio.
What this page can’t tell you
- Distances here assume a 16:9 picture, the published optical throw range and no digital keystone. Measure lens to screen, then check the installation in the manufacturer calculator. Nothing here claims a hands-on test of brightness, contrast, color or input lag.
