Our take
Brookstone's Pocket Projector Slim, model 842364, is best understood as a tiny, battery-capable projector for a small and deliberately modest picture. Its manual gives a native 640 × 360 resolution, HDMI input, an internal rechargeable battery, and a 25-lumen brightness figure. That figure is not labeled ANSI, and the manual does not establish runtime or throw distance. These limits make exact expectations more useful than the broad word portable.
A pocketable projection experiment when a small image, an external HDMI source, and a separately checked battery are acceptable..
It is not a good fit for a bright room, a large screen, readable fine text, a defined ANSI threshold, or a trip where battery runtime must be guaranteed.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Brookstone's model manual documents a native 640 × 360 image rather than leaving the panel resolution to a listing title.
- An HDMI input provides a named wired source path for a compatible player or computer.
- The manual identifies a rechargeable internal battery, so cordless operation is part of the model design.
What to weigh up
- The 25-lumen figure is not labeled ANSI and does not support a bright-room comparison.
- The manual does not state battery runtime, and the remaining capacity of any older unit is unknown.
- Native 640 × 360 resolution and the missing throw chart make large, detailed pictures a poor assumption.

What the features mean for you
What does 640 × 360 mean for the picture?
Brookstone's 842364 manual identifies the projector's native image as 640 × 360 pixels. That is a small pixel grid by current home-cinema standards, so text, spreadsheets, game menus, and detailed scenes will not have the fine structure of a native HD projector. The manual's resolution is more useful than a higher input-format label: a connected source may send another format, but the projector still displays through this panel. Keep the intended image modest and judge whether its detail is enough for your particular viewing distance.
How should the brightness number be read?
The manual lists 25 lumens, but it does not label the measurement as ANSI. That means the figure cannot be compared directly with ANSI-lumen ratings from models whose manufacturers identify that method. It still signals that the product belongs in a dim setting with a small image, not a sunlit room or a large, washed-out wall. Ambient light, screen area, surface color, and the unit's age all change the result. Ask for a demonstration at the size you plan to use rather than treating the number as a current performance guarantee.
What can the internal battery support?
Brookstone documents a rechargeable battery inside the Pocket Projector Slim, which is a genuine portability advantage when an outlet is inconvenient. The reviewed manual does not give a runtime, however, and it cannot describe the present health of a used battery. Request a full-charge demonstration using the actual unit and the intended HDMI source. Check whether its charger is present and working. Do not plan a full-length film, outdoor event, or long presentation around an assumed number of hours that the source does not provide.
Which source connection is documented?
The manual identifies HDMI as an input, giving the user a straightforward wired route from a compatible media device. It does not document a built-in streaming-app platform, so the projector should not be treated as a standalone smart TV. Choose a source that can send a supported HDMI signal and check any adapter needed by a phone or laptop before traveling. A connector's presence does not guarantee that every protected service or device will work through an adapter; verify that chain with the actual equipment.
How should placement be checked?
The saved model manual does not provide a throw ratio or a usable distance chart. Measure the available projector-to-wall space and ask the seller to show the image at the intended size before relying on this model for a room layout. Focus and picture alignment should be tested on the exact unit, but neither a successful focus adjustment nor digital image correction would establish close-wall ultra-short-throw optics. Keep the product on a stable surface, allow airflow, and avoid buying it for a fixed mount until the missing placement information has been resolved.
Who is likely to appreciate the Pocket Projector Slim?
This Brookstone model suits someone who values a tiny self-contained projector and can accept low brightness, a 640 × 360 image, an external HDMI source, and uncertain battery endurance. It may be useful for a short informal demonstration or an intentionally small picture in a dark space, provided the actual battery works. A buyer needing clear classroom text, bright sports, a large movie screen, or a dependable multi-hour run should shortlist a model with stronger documented measurements. Confirm the exact 842364 label and charger before considering an older offer.
What else to compare
Compare Miroir MP150A for documented native 720p and Lenovo P0510 for a manual-stated battery runtime, while checking the condition and compatibility of any older unit.
Before you buy
Is model 842364 native HD?
No. Brookstone's manual gives a native 640 × 360 pixel image.
Are the 25 lumens ANSI lumens?
The manual does not label that figure ANSI, so it should not be used as an ANSI comparison.
How long does its battery last?
The reviewed manual confirms a rechargeable battery but does not establish runtime; test the exact unit.
Can it run streaming apps by itself?
The manual documents HDMI input, not an included streaming-app platform. Use a compatible external source.

The decision
Consider the 842364 only when its small, dim image is enough and the seller can demonstrate the battery and HDMI path.
