Which projector suits your carrying and charging setup?

Choose by handling preference and documented power requirements. The D2325 guide labels a handle; its US page lists a 19 V / 4.74 A input and the guide describes the provided-adapter charge procedure. Capsule is documented for Type-C PD charging, with a soundcore power-bank checklist. D2325 dimension labels conflict, so this is not a fit, runtime, or image-quality verdict.

The buying question

Do you prefer the D2325 guide-labeled handle or the Capsule body shape, and does your planned portable supply match the charging requirements documented for the exact model?

The D2325 guide labels a handle and specifies charging with the provided adapter and power cord; the D2325 page lists a 19 V / 4.74 A input. The Capsule US page identifies Type-C PD charging, and soundcore publishes a power-bank checklist for it. Mars dimension labels conflict, so the sources do not establish a fair footprint or height comparison.

Quick verdict

Choose Nebula Mars 3 Air (D2325) if

  • You prefer the D2325 guide-labeled handle and can use its provided-adapter charging procedure; verify any alternate supply against the exact input and connector.

Choose Nebula Capsule 3 Laser (D2426) if

  • You prefer the Capsule body shape and want a documented USB-C PD bank route, using a bank that meets soundcore’s published requirements.

When the recommendation changes
  • If a tight shelf, bag opening, or clearance is decisive, do not use the conflicting D2325 dimension labels to predict fit; verify the exact unit dimensions with soundcore or measure the unit.
  • If portable charging is decisive, match the exact source and connector to the selected model’s documented input; Capsule has a published USB-C PD bank checklist, while no specific alternate Mars supply is confirmed.

The differences that matter

Carry And Placement Workflow

Nebula Mars 3 Air (D2325)

Nebula Mars 3 Air D2325: its exact US guide labels a physical Handle on the projector. The guide and US product page label the same dimensions in conflicting axis orders, so those dimensions are not used to describe footprint or height.[1, 4]

Nebula Capsule 3 Laser (D2426)

Nebula Capsule 3 Laser D2426: the US page lists a 3.3 × 3.3 × 6.7 in body. This measurement is not used to claim that it fits better than Mars.[2]

What this changes: A buyer who prefers a labeled grip has a specific D2325 feature to consider. For Capsule, use its listed body size when checking a planned storage space. Because the D2325 page and guide conflict on dimension order, they do not support a side-by-side footprint or height winner; verify the exact Mars dimensions before buying for tight clearance.[1, 4, 2]

The better fit depends on your priorities

Battery And External Power Workflow

Nebula Mars 3 Air (D2325)

The Mars 3 Air US page lists a 19 V / 4.74 A input. Its exact D2325 guide describes charging the built-in battery with the provided adapter and power cord, and says to try a different adapter rated at least 90 W if needed. These sources do not confirm a particular power-bank model or connector arrangement.[1, 4]

Nebula Capsule 3 Laser (D2426)

The Capsule 3 Laser US page identifies Type-C PD charging. soundcore support says a charging power bank should provide at least 45 W, support PD 2.0, and cover 5–20 V.[2, 3]

What this changes: If you plan to recharge from USB-C PD, Capsule has a specific documented power-bank checklist: at least 45 W, PD 2.0, and 5–20 V. For Mars, compare the planned supply and connector with its published 19 V / 4.74 A input; the guide documents the provided adapter and cord, not compatibility with a particular alternate supply. This identifies the documented input requirements without claiming Mars cannot use a bank.[1, 4, 2, 3]

The better fit depends on your priorities

Best for your routine

Carrying by a grip or checking storage fit

The better fit depends on your priorities

The exact D2325 guide labels a physical handle. Capsule’s US page lists its body dimensions for a buyer to check against a planned space. The D2325 page and guide disagree on dimension order, so they do not establish which projector has a smaller footprint or height.

Recharging from a portable power source

The better fit depends on your priorities

Capsule has a documented USB-C PD power-bank checklist. Mars has a published 19 V / 4.74 A input and a guide-described included-adapter charging procedure. Match the exact supply and connector to the chosen model; do not infer that Mars is incompatible with all alternate supplies.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Prices change; a premium is only useful if the handling feature or documented charging requirements match your setup. Compare current offers for these exact standalone models.

There is not enough price history to recommend buying now or waiting.

Limitations

  • The D2325 US product page labels 178 × 122 × 133 mm as H × W × D, while the exact D2325 guide labels the same numbers L × W × H. No Mars footprint or height comparison is made; confirm exact dimensions for a tight-space decision.
  • Soundcore’s US product page and support table disagree on Mars 3 Air Eco-mode runtime; neither figure is a guaranteed viewing time or basis for ranking these models.
  • Capsule’s page gives conflicting weight figures; weight is not used to rank portability.
  • The Mars sources specify a 19 V / 4.74 A input and describe the provided-adapter charging procedure, but do not confirm compatibility with a particular alternate power bank or inverter. Match the exact supply and connector with soundcore before relying on it.
  • No hands-on testing was performed. Brightness, image quality and actual runtime under a particular setup were not compared.

Questions shoppers ask

What should I check before using a power bank with the Capsule 3 Laser?

soundcore support recommends at least 45 W output, PD 2.0, and a 5–20 V range for charging the Capsule 3 Laser. Check those specifications on the exact bank; capacity alone does not confirm it meets this guidance.

Which projector is easier to fit in a bag?

The Capsule page lists a 3.3 × 3.3 × 6.7 in body. The D2325 US page and guide label the same dimensions in different axis orders, so those sources do not establish which has the smaller footprint or height. Verify the exact Mars dimensions if clearance is tight.

Which one lasts longer on battery?

The published figures do not support a clear runtime winner. Soundcore’s Mars product page says 2.5 hours in Eco mode while its support table lists 3 hours; the Capsule page and support table list 2.5 hours. Mode and brightness also matter, so treat these as manufacturer claims rather than a guaranteed session length.

Does the Mars 3 Air have a carrying handle?

The D2325 user guide labels a Handle on the projector in its At a Glance section. The Capsule page lists its body dimensions; compare the actual unit and how you plan to carry or store it.

Methodology and sources

Compared the D2325 guide-labeled handle and Capsule listed body dimensions without using the conflicting Mars dimension order to rank fit. Compared the stated Mars 19 V / 4.74 A input and included-adapter instructions with Capsule Type-C PD charging and its model-specific power-bank checklist. Runtime and weight conflicts remain disclosed; no alternate Mars supply is called compatible or incompatible.

Research assistance organized the published dimensions and power requirements. No projector was measured or tested.
