Our take
Consider the M45 when the useful feature is a projector that can move with a small HDMI source and does not need a permanent power lead during viewing. Its battery, focus wheel, tripod socket, and USB power output support that simple portable role. The guide leaves the image specifications and runtime open, so this is a convenience-first choice rather than a predictable large-screen recommendation.
Portable HDMI viewing when a battery-powered setup matters more than a documented image specification.
Skip it if you need a known native resolution, a comparable brightness rating, a measured screen distance, or a promised runtime. It is also a poor fit for someone expecting USB to carry video or for a self-contained app projector.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The rechargeable battery allows temporary viewing without a mains lead during the session.
- HDMI accepts an external video source, while a tripod socket gives a flexible mounting point.
- USB output can power a separate streaming device without being mistaken for a video input.
What to weigh up
- The manufacturer guide does not state native resolution or comparable ANSI brightness.
- Battery runtime and throw ratio are not established, which limits planning for longer sessions.
- Phone playback may require a separate video-capable HDMI adapter; USB itself does not accept video.

Full review: how the features affect your choice
What the features mean for you
A battery changes where the projector can go
Miroir identifies the M45 as a micro projector with an internal rechargeable battery. That makes it easier to move between a bedroom, a table at a friend's place, or another temporary viewing spot than a projector that must stay beside an outlet. The manual does not give a battery runtime, however, so a long film or a full evening should not be planned around an assumed number of hours. Battery condition on any current unit is also unknown.
Treat the image specification as an open question
The shared M45/M55 guide does not give a native pixel count, standardized brightness, screen-size range, or throw ratio. That is a material limit: a buyer cannot use the saved documentation to estimate how much fine text will resolve or how large an image will remain useful in a lit room. Miroir's short guide is useful for connections and controls, but it does not support a resolution or brightness ranking against better-documented models.
Use HDMI for video and USB only for power
The guide documents HDMI video input, micro-USB charging, 3.5 mm audio output, and a USB port that can supply power to a streaming stick or phone. It explicitly says the USB port does not accept video. A phone may need a separate adapter that sends video over HDMI; a charging cable alone does not establish that the picture will appear. This keeps the setup flexible, but it still depends on the separate source and its adapter.
A tripod socket helps with temporary placement
Miroir shows a tripod socket and a focus wheel, so the M45 can be aimed from a small stand rather than a permanent shelf. The saved source does not give a throw ratio or lens shift, and a tripod does not replace a flat, stable screen position. Measure the actual setup and allow time for manual focus. The guide also does not establish ultra-short-throw placement, so a close-to-wall arrangement should not be assumed.
Check the power and source accessories
Before choosing an M45, confirm that the exact unit includes a working charger and that its battery still holds a useful charge. The documentation does not establish present battery health, runtime, or a particular phone-adapter bundle. An external HDMI streamer can be powered from the projector's USB output, but app compatibility belongs to that separate device and can change. These checks matter more here than claims about an undocumented screen size or brightness number.

Before you buy
Can the M45 show video from its USB port?
No. Miroir's guide says the USB port is for power output and does not accept video; use HDMI for a video source.
Does the M45 have a documented battery runtime?
The checked M45/M55 support guide confirms rechargeable battery operation but does not state a runtime or current battery condition.
Can I connect a phone directly by charging cable?
The guide does not establish direct USB video from a phone. A video-capable phone adapter and HDMI connection may be required.
