Welcome viewers today on TV Box stop I have a compact mini LED projector from Sentrym.
This is the Sentrym L1, and it’s a 480p compact projector with built-in Android 9
operating system, built-in touchpad controls, and digital keystone correction.
In this review we’ll take a look at its compact innovative design, it’s input output
peripherals, it’s built-in Android operating system, it’s touchpad controls, and its
display and sound quality.
In the end we’ll look at its pros and cons and you get to decide whether this product
is right for you.
So stay tuned my full review is up next.

So head on over to tomtop.com and take advantage of these flash sales, discount coupons, and
limited time offers.
To be taken directly to these offers along with the open box and used items section,
see the link in the description directly below is video.
So the box you have the Sentrym L1 unit itself.
You get one IR remote control.
One micro HDMI to full-size HDMI cable.
A mini tripod.
A micro USB charging cable.
A 5V 3A DC power adapter.
And a user manual.
For its design its body is mostly made of plastic with touchpad controls to the top
that consists of volume controls, a mute button, a home button, and a back button with the
touchpad function at the center.
You also have an LED indicator.
To the rear you have one HDMI 1.4 port, one USB 2.0 port, a reset pinhole button, a headphone
jack, and a micro USB charging port.
To one side you have a microSD card reader and a focus wheel.
On the opposite side you have a power standby button, and a power switch.
At the front you have the projector lens with an intake cooling vent for the built-in cooling
fan.
To add some strength to the body, the strip along the sides is made of metal.
And below the projector you have another plastic panel with for antiskid rubber feet, a screw
hole for mounting to the included tripod or any other type of you may have, and a speaker
vent for the built-in speaker.
So to set it up you have a couple of options seeing that it comes with a built-in rechargeable
battery.
First you have the option of using the power adapter with the micro USB cable.
This will ensure long hours of use.
Next you can charge it and use the internal rechargeable battery which will give you approximately
two hours on a full charge.
The third option is where you can use a power bank that will give you a mobile option, because
it will first run on the power bank’s power then resort to the internal battery.
This can double or triple the viewing time especially if you carry this on a trip or
use it outdoors.
So here I have it set up on the included mini tripod for this demonstration, and I’m also
using my projector stand to give it some height to focus it on my projector screen.
When you startup L1 you are greeted with the Sentrym logo and Android animation for approximately
38 seconds before you were taken to the Android launcher.
The launcher is a hybrid between an Android TV Box launcher and a projector launcher.
To access the settings of the projector you simply click on settings.
They have created eight easy-to-use sections that allow you to adjust its configuration.
Under network settings is a very straightforward you simply select your Wi-Fi network and enter
your password.
This projector has dual band 2.4+5 GHz Wi-Fi as you will see in a moment.
Under Bluetooth it’s the same, simply select the Bluetooth device you would like to connect
to and approve it.
Under language settings you have 53 various languages to choose from.
You have date and time settings.
Under Projection settings where you have auto screen rotation.
Manual screen orientation.
Brightness adjustment.
Vertical keystone correction where you can set it to auto or manual.
You have the same settings for the horizontal keystone correction.
And the final option is your zoom settings.
You have audio settings all this really does is adjust the volume.
You have other settings.
The settings is for the Android installation.
However there is no display settings to adjust the its picture quality.
And the final section is basic hardware information.
Before I proceed with the video demonstration I will quickly run through its system and
hardware information and the features you get with the Android operating system.
The main-board on the inside is an Amlogic macaroni board, with 2GB of DDR3 RAM, and
16GB of internal storage from which this is the remainder.
The Bluetooth version is 5.0 and that’s according to the product description.
Its CPU which is an Amlogic CPU, is a 64-bit quad core cortex A55 CPU clocked at 1.7 GHz
configured in 32-bit mode with support for only 32-bit ABIs.
It’s GPU which is of the Mali G31 has a max resolution of 854 x 480 with open GL ES
version 3.2 support.
Under network it shows that it has dual band 5GHz Wi-Fi support.
Under battery it shows the status of the rechargeable battery.
It’s operating system is Android 9 pie, and it shows that the projector is rooted.
Under devices it shows that it does not have vulkan support.
With its internal cooling fan and a hot projector lens, it has an operating temperature of around
61°C.
Under codecs it has all the decoders of the playback of 4K videos and videos with digital
surround sound formats.
However it would be scaled down to 480p on the projection display.
And that’s its system and hardware information.
With this project the Android operating system is rooted which gives you the freedom to install
any app without restrictions, as you have a full access to the Google play store.
It has Google Widevine Level 3, with no HDCP DRM protection this means it can only play
premium movie streaming services in standard or basic quality.
The rooted checker app shows that the operating system is rooted.
The rooted checker app shows that the operating system is rooted
You can play YouTube videos and select 4K quality just keep in mind the actual projection
display is
a 480p.
You can use alternative launchers, along with custom wallpapers, and and this launcher comes
with a navigation bar and status bar.
It comes preinstalled with the official version of Miracast for Android devices, and Air-play
for iOS devices
It has a mobile remote control feature where you can control the projector using your cell
phone or tablet.
This EasyShare feature also allows you to share files between your mobile device and
the projector.
It has the ability to play 3D videos but only from self hosted filed.
To play 3D videos the manual states that you will need a pair of 3D glasses, and you will
need to disable auto horizontal keystone correction and the screen zoom feature.
And in order to play the video file you will have to use the default video player that
has a 3D feature that has options while playing 3D videos.
Here’s a quick demonstration.
And
finally it has Bluetooth 5.0 and with this you can connect your Bluetooth controls such
a Bluetooth air-mouse, gamepad controller, and Bluetooth speakers.
I will now fine-tune its settings for optimal display and play some videos and one Android
game to test its picture quality and internal speaker sound quality.
So its picture brightness is not the best but it is watchable, however I found it difficult
to adjust the focus due to its focus wheel being very soft and tiny at the same time.
The internal speaker is not very powerful but you can clearly hear it.
Also there is little no noise from the internal cooling fan.
Now I will connect it to my audio receiver via Bluetooth to test for audio playback latency.
As you can see, it connected to my receiver via Bluetooth successfully.
It even displays Sentrym on the receiver’s display.
So the projector connected to my receiver via Bluetooth successfully and I didn’t
experience any lag in audio during the playback.
And while it’s connected to my receiver I will now play one Android game just to check
its graphics rendering.
So the gaming quality is not the smoothest but it is playable.
So viewers have come to the end of this review.
The Sentrym L1 is a good option if you are looking for a mobile projector that’s small
enough to fit in your pocket, with lots of features compact into it small form factor,
that’s ideal to take camping or could be a great form of entertainment if you work
in a small space and in need just a little bit of cinematic experience to keep you occupied
especially if you don’t have a TV.
My only wish for this device is that its lumens could have been a bit brighter, and its focus
wheel could be larger and firm.
And with that said if you are interested in the L1 you can get it at an affordable price.
