Our take
The PH150B is a portable 720p projector for short viewing sessions where a built-in battery and simple external-source connections are useful. LG rates the battery for up to 2.5 hours, but its brightness documentation needs care: the product page says 130 ANSI lumens while the specification-sheet footnote describes a perceived-equivalent basis. Treat the model as a small, dim-room option and check the battery, remote, charger, and image on any used unit.
Portable viewing in a dim room when battery use matters more than a large or highly detailed image.
It is not a match for native Full HD, bright-room viewing, long battery sessions, or a projector with confirmed built-in streaming apps.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- LG specifies native 1280 × 720 LCOS imaging and battery playback up to 2.5 hours.
- HDMI/MHL, USB, and screen share provide several ways to connect a source.
- Vertical auto-keystone can simplify a temporary placement when the projector is not perfectly level.
What to weigh up
- A 720p native image has less detail than Full HD for small text and fine graphics.
- LG's product page and specification-sheet footnote do not present brightness on a consistent comparable basis.
- The discontinued model's battery health, charger, remote, and exact offer contents are unit-specific.
The key details

What the features mean for you
Decide whether a built-in battery changes the setup
LG identifies the PH150B as a portable LED projector and rates its internal battery for up to 2.5 hours. That supports moving it between rooms or using it where a convenient power cable is unavailable, without needing a separate power bank for the rated use. The figure is a manufacturer maximum, not a promise for a particular used unit; age, charge history, brightness setting, and playback conditions can change runtime. For a long film, have the adapter available. A battery makes the PH150B easier to reposition, but does not make its image suitable for every room or screen size.
Keep the native image distinct from supported inputs
LG specifies a native 1280 × 720 LCOS image. A laptop or streaming device may send a higher-resolution signal, but that input does not turn the projector into a native 1080p model. The difference matters when comparing detailed subtitles, computer interfaces, and graphics across a large screen. A simple movie viewed from a modest distance may place less demand on fine detail than a close seat or small text. Choose it for its portability and basic picture format rather than treating broad compatibility wording as a claim about native resolution.
Read the brightness claims with their qualification
LG's product page lists up to 130 ANSI lumens, but the specification sheet includes a footnote describing its brightness as a perceived equivalent to a lamp projector. Because those statements do not establish one clean, comparable ANSI basis, this guide does not put 130 into the matching profile as a verified ANSI figure. The number can remain visible with its qualification, and should not be compared as if it were a standardized measurement. In practical planning, favor a small image and a dim room, then inspect the specific unit for focus, uniformity, and discoloration rather than assuming its original output remains.
Plan around the listed source connections
LG lists HDMI/MHL, USB, screen sharing, Bluetooth audio output, and a small mono speaker. HDMI can connect a laptop, media player, or compatible streaming device, while screen share offers a cable-free route from supported devices. Neither screen sharing nor Wi-Fi wording establishes an included streaming-app system, and protected video services can restrict mirroring. Check the exact phone, adapter, cable, and content requirements before relying on wireless playback. The onboard speaker may suit a personal session, but external Bluetooth audio is another documented route if you need sound elsewhere in the room.
Measure a normal projector position
LG's product material illustrates a 40-inch image from about 4.07 feet, which is a conventional projector distance rather than an ultra-short-throw placement. The projector needs a stable surface with a line to the screen, so measure the lens-to-screen distance and desired image before deciding where it will sit. Vertical auto-keystone can correct some tilt, but digital correction is not optical lens shift and does not remove the need to position the unit sensibly. Leave room to connect the source and power adapter, and do not infer a wall-adjacent setup from the word portable.
Inspect the used-unit details that affect ownership
LG lists the PH150B as discontinued, so any specific offer may be used or old stock. The model's original battery rating cannot establish the health of a battery now. Ask whether it charges and runs unplugged, verify the supplied adapter and remote, test HDMI and USB with a known source, and look for an even image and stable focus. The saved candidate title is not proof of accessories or condition. These checks determine whether the portable design still works for the intended session; they do not imply that any particular seller has a working unit or a complete bundle.
What else to compare
For native Full HD in a portable form, compare the Philips PicoPix Micro 2 while accounting for its unspecified native pixel count and output; for a fixed home setup, compare models with stronger documented image and placement specifications.
Before you buy
Is the PH150B native 1080p?
No. LG specifies a native 1280 × 720 LCOS image; a higher-resolution input does not change its native pixels.
Can its 130-lumen figure be compared as ANSI?
LG's product page says 130 ANSI lumens, but the specification sheet qualifies the brightness basis. This guide leaves a comparable ANSI value unassigned.
How long is the battery rated to run?
LG lists up to 2.5 hours. Runtime and battery condition can differ on an older or used projector.

The decision
The PH150B makes sense when battery-powered movement and basic external inputs matter more than Full HD detail. Preserve LG's brightness qualification and verify battery health on the exact unit.
