BenQ GV50 vs XGIMI MoGo 4

What you'll actually notice

Both are genuinely portable Full HD projectors, but they feel different the moment you pick them up and place them in a room.

The MoGo 4 is the lighter, simpler travel companion at about 1.31kg. The GV50 is heavier, but it puts more emphasis on bedroom use, ceiling projection and built-in audio. If you are constantly carrying the projector around, the weight difference matters. If it mostly moves between a bedside table, living room and ceiling-facing position, the GV50's physical design can be more useful than shaving off some weight.

Brightness is not the clean deciding factor because BenQ quotes ANSI lumens and XGIMI quotes ISO lumens. Treat both as evening/controlled-light projectors and choose based on how you actually move and aim them.

What changes the choice

Which is easier to move?

MoGo 4 weighs about 1.31kg, while GV50 is about 2.1kg. That difference is easy to feel if you carry the projector between rooms or pack it away frequently.

GV50 is still portable, but it spends some of that weight budget on a more substantial rotating chassis and audio system. MoGo 4 is the cleaner choice when carrying convenience itself is the priority.

Which is better for a bedroom or ceiling?

Both are designed for flexible placement, but GV50's rotating body is especially well suited to ceiling and bed-facing projection. MoGo 4 uses a 360-degree stand and is also easy to reposition.

The decision is less about whether either can tilt and more about how much you value BenQ's bedroom-specific form factor. If ceiling viewing is a recurring use case, GV50 has the stronger physical story.

How do the brightness claims compare?

GV50 is rated at 500 ANSI lumens. MoGo 4 is rated at 450 ISO lumens.

Because ANSI and ISO are different measurement conventions, do not treat 500 as a clean numerical win over 450. Both remain controlled-light portable projectors. If you need a meaningful step up in stated portable light output, Hisense P1 is the more relevant comparison at 1000 ANSI lumens.

Which has the better audio option?

GV50 combines two 4W speakers with a 10W woofer, while MoGo 4 uses 2 x 6W Harman/Kardon speakers.

Wattage alone does not prove sound quality, but BenQ is clearly putting more hardware emphasis on low-end output. If you want the projector to handle bedroom audio without another speaker, GV50's 2.1-channel design is a real consideration.

What about battery and smart TV?

Both include built-in batteries and Google TV. MoGo 4 has a clearly stated up to 2.5-hour Eco-mode video runtime in the verified record; GV50's card is more about the presence of the battery than a directly comparable runtime figure.

If a known session-length claim matters, MoGo 4 is easier to plan around. If the physical bedroom setup matters more, GV50's design can outweigh that difference.

The practical choice

Pick MoGo 4 if portability means carrying the projector often, keeping the setup light and having a clearly stated Eco-mode battery window.

Pick GV50 if portability means moving it around the home, pointing it at unusual angles and relying on the projector's own speakers more often.

For most buyers, that difference in how you use the projector will matter more than trying to split hairs over two brightness numbers measured under different standards.

There is also a simple ownership difference: the MoGo 4 rewards you for carrying it, while the GV50 rewards you for changing how and where you point it. Someone travelling between locations may notice 1.31kg every trip. Someone using the same projector around a home may notice the GV50's aiming flexibility and fuller audio much more often.

Think about one full evening away from the usual setup. If you are carrying the projector, charger and other gear with you, the MoGo 4's lower weight and clearly stated Eco-mode runtime are easier to plan around. If the projector is staying inside the home, the GV50's extra weight matters less and its aiming flexibility and stronger audio package can make the experience feel more complete without adding another speaker.

When to choose BenQ GV50

• Ceiling or bedroom projection is central.
• You want the more substantial built-in audio system.
• You do not mind the extra weight.

When to choose XGIMI MoGo 4

• Lower weight matters.
• You want the verified 2.5-hour Eco-mode runtime reference.
• You prefer XGIMI's lighter battery-first approach.

Choose neither when

Choose neither if native 4K is a hard requirement or you expect frequent bright-room daytime use.

PIQSY conclusion

Choose GV50 for bedroom/ceiling flexibility and stronger built-in audio; choose MoGo 4 when lower weight and a lighter battery-first setup matter more.

The best choice is the one that removes the bigger compromise in your actual room; a small specification advantage should not override placement, use case or workflow.
