Our take
The LG PH300 is a compact portable projector with a documented battery, an ANSI-labeled 300-lumen output, native 720p DLP, and a built-in digital TV tuner. It trades Full HD detail and high light output for a cordless setup and small footprint. Its battery runtime is a manufacturer rating, not a guarantee for an older battery, and it does not replace a streaming platform.
Short portable viewing where battery operation, USB playback, or the built-in tuner matters more than Full HD.
It is not a native Full HD choice, a bright-room projector, or a documented built-in streaming-app device.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- LG specifies 1280 × 720 native resolution and 300 ANSI lumens.
- The embedded battery is rated for up to 2.5 hours in LG's published specification.
- A digital TV tuner and USB media playback provide source options beyond a single HDMI device.
What to weigh up
- The 720p panel has less fine detail than native Full HD home projectors.
- At 300 ANSI lumens, room lighting and screen size need careful control.
- The battery in an old unit may no longer deliver its original rated runtime.

What the features mean for you
How much detail does native 720p provide?
LG specifies a native HD panel at 1280 × 720 in a 16:9 shape. This can suit casual movies, clips, or presentations on a modest screen, but has fewer native pixels than Full HD and 4K models. The HDMI input can accept higher-resolution signals, yet scaling does not add panel detail. Text and fine subtitles become harder to read as the image grows. If the projector will travel between rooms or be used for a small screen, that compromise may be reasonable. Choose a native 1920 × 1080 model when fine detail is more important than carrying weight or battery use.
Is 300 ANSI lumens enough for the setting?
LG labels the PH300 output up to 300 ANSI lumens, which makes its brightness basis clearer than an unstandardized lux or lumen claim. The number is still modest and should be paired with a controlled-light room and a practical image size. A larger diagonal spreads the available light over more area; daylight or bright overhead lighting can wash out contrast. The figure describes the model specification, not the present output of a used unit. Ask for a current demonstration and inspect image uniformity. A projector with a higher documented ANSI figure is a better choice when a large image or room lights are unavoidable.
What does the built-in battery change?
LG rates the embedded battery for up to 2.5 hours. That can support a short movie or presentation away from a wall outlet, but runtime varies with battery age, settings, and content. The rating belongs to a new model specification and says nothing about a particular used unit. Confirm that the battery charges and holds power before relying on it. The PH300 can also use an AC adapter, so it remains useful at a desk or bedside when plugged in. If longer cordless sessions matter, compare a model with a documented larger battery or plan a safe power supply.
Does it need a separate streaming stick?
LG includes a digital TV tuner and USB host playback for supported files, plus one MHL HDMI input. Those functions do not make the PH300 a built-in streaming-app projector. A media stick or phone may be connected over HDMI or MHL, with the correct adapter and power. The TV tuner can be useful where an antenna signal is available, while USB playback can cover supported local files. Check that the current streaming device and adapter match the input and that the desired service works on the external player. For app compatibility without extra equipment, choose a projector with a documented platform and verify current service support.
What should I check before carrying it around?
LG's product information lists a 20–100-inch image range and a throw ratio around 1.64:1, with vertical automatic keystone correction. That is conventional placement rather than an ultra-short-throw lens. The small body and built-in battery make moving the unit simpler, but check focus and projection distance each time it is set up. The LED source is rated up to 30,000 hours; the age and condition of a used projector still need inspection. Confirm the adapter, remote, battery behavior, tuner region, and HDMI cable in the package. The PH300 suits portable viewing when a modest image is acceptable and the unit's battery checks out.
What else to compare
Compare a higher-ANSI portable if the room is bright or the screen is large, or native Full HD models if image detail matters more than cordless use.
Before you buy
What is the PH300 native resolution?
LG specifies HD 1280 × 720 native resolution, even though the input accepts other video timings.
Is its brightness rated in ANSI lumens?
Yes. LG's specification sheet lists up to 300 ANSI lumens for the PH300.
How long does the built-in battery last?
LG rates it for up to 2.5 hours; the remaining runtime of a used battery is unknown.
Does it include Netflix or other streaming apps?
LG documents a tuner and USB playback, not built-in streaming apps; use an external source device.
