Our take
The Mitsubishi PK20 is genuinely pocket-sized at about 500 g and can operate with an optional rechargeable battery pack. Its native 800 × 600 DLP panel and 25-lumen manufacturer figure narrow the use case to a tiny dark-room picture. It is portable in size, but it is not a bright, self-contained battery projector.
A legacy personal projector for a very small picture when the buyer accepts a separate battery pack and low output..
Skip it for a bright room, a large screen, native HD detail, or a requirement for a built-in battery and known ANSI brightness.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The roughly 500 g body is far lighter than a conventional presentation projector.
- An optional BT-PK20R battery pack supports about two hours of operation according to the brochure.
- The inputs include VGA/component, composite, S-Video, and an SD-card reader.
What to weigh up
- The 25-lumen output figure has no ANSI method and is exceptionally low for a projected image.
- Native 800 × 600 detail is limited for modern video and small on-screen text.
- Battery operation depends on a separate optional pack, not an internal battery.

Full review: how the features affect your choice
What the features mean for you
Pocket portability is the clear advantage
Mitsubishi's brochure describes a 500 g projector measuring about 123 by 97 by 48 millimetres. That makes the PK20 easier to carry than the 5.9 lb Epson PowerLite 62c or the 13.7 lb Panasonic PT-FW100NTU in this batch. The size can help when a projector must travel with a laptop or camera, but weight is only one part of portability. The included AC adapter is still needed unless the optional battery pack is present, and the low light output limits where the device can be used effectively.
A tiny image protects the limited light output
The product brochure lists 25 lumens and a 12–60 inch image range; it does not label the brightness as ANSI. Do not compare the number as though it shared the method used for the Epson 62c or Optoma PRO250X. The brochure itself recommends an optimal display around 40–50 inches. That small scale and a dark room make more sense than a large screen. This is a planning inference from the maker's own specification, not an independent brightness measurement.
SVGA is a clear compromise in image detail
The single-chip DLP engine is native 800 × 600. A higher-resolution computer signal may be accepted in compressed form, but it does not increase the native pixel grid. That is sufficient only when the image is small and fine text is not central. Compared with the native Full HD Heyup Boxe, the PK20 trades a much smaller body for substantially less detail. A buyer should choose it for carrying and a tiny picture, not because a compatible video format implies modern display resolution.
The optional battery is separate from the projector
Mitsubishi lists the BT-PK20R lithium-ion pack as an option and estimates roughly two hours of battery operation. The source does not describe the battery as built in, so a listing that lacks the pack does not satisfy an outlet-free requirement. Confirm that the exact unit includes a working pack and charger before relying on cordless use. The standard AC adapter remains the simpler power path, and battery age can affect endurance on an older model.
Legacy inputs define practical compatibility
The brochure lists a 15-pin VGA/component input, composite, S-Video, an SD-card reader, and audio connections. This can suit an older camera, computer, or video source, but no HDMI input or app platform is documented. A modern HDMI-only source would need an adapter, and an adapter cannot improve native detail. Check the exact cable path before carrying the projector to an event. Its 0.2 W mono speaker is also very small, so nearby personal listening is a more realistic audio expectation than filling a room.
