The younger brother did not know what kind of wind had recently been drawn. Obviously, the TV size at home was still decent. Then I went to buy a hand-held projector. Aside from the bad habits of spending money, the projector was really small. Now that he has bought it, I will be ready to make a short review.
Cool Music (COOLUX) Q7 Ultimate Home Projector Projector (150 lumens mobile phone / micro / portable projection) 1699 yuan Jingdong to buy Cool Music Q7 projector out of the box 
This cool music as Q7 box itself is not large. The inside is equipped with a cool music Q7 host a remote control, tripod, power outlet, instruction manual.
The design of the power outlet is very interesting. It may be designed to be separated for easy outing and portability. One thing I can't understand is that some sockets are not foldable. They can be designed to be folded. Why must they be designed as separate types? If you meet someone like me who is like Madagascar, it is estimated that you will only take away the big ones below. The top face can easily be forgotten....
Simple tripod. Small is very small, workmanship is generally, people feel it will break with some force, a little lower the price of the projector.
The instructions are also compact. Just inside the detailed mobile phone with the screen function because the font is too small, some see how the phone screen is not operating.
I really hope that this remote controller can bring voice functions. It feels like it is being operated with a remote controller. In particular, entering the WIFI password is still somewhat troublesome. Especially for people like me who have long passwords at home, they still need some patience.
Cool music as Q7, in the hands of a girl, I can open it five fingers can grab it like a doll machine. And this cargo itself weighs less than three hundred grams. It is really convenient to go out to use.
The back of the projector. The middle hole is used to fix the tripod. There are four non-slip heat. This is also a fence-like heat sink. The front end has a small angle support piece. If the projected distance is relatively close and there is no obstruction in front of it, it still has some minor effects. Can you buy a projector instead of a large one?
This is its post "ass." In addition to the charging jack, there are HDMI port and USB port, as well as a headphone port. The middle of the receiving infrared window. Personally think that the usefulness of the headset hole is not very great.
There are three buttons on one side of the fuselage, of which the relatively independent one is the button of the on/off switch, and the other two are focusing keys. The hole that does not appear to be the starting point is the reset hole.
This is the front of the projector, with the lens on the left and the heat vent on the right. It is a pity that there is no cover in front of the camera. No cover is easier to drop than a cover. Especially like my brother, who bought things and didn't care much about them... It can be equipped with a jacket even if it's not covered. Unfortunately, it doesn't have a configuration. If you want to use it longer, you have to spend money on it.
Press the power button for almost two or three seconds and the projector will start working. At this moment, you can see the operation keys hidden in the body, and the power indicator light which is easily ignored by the upper right corner. After all, the design is a bit small. If it is turned on during the day, it is really unlikely to find it.
This is the effect of hand-held projectors projected in the bookcase during the day. After all, there is no window in the study to dim its own light, so this effect should be equivalent to the effect of pulling the curtain in the daytime. Projection size should have a 13-inch notebook size
This is the effect of the wall on the aisle during the day. Because my back is a house, the room has a window facing the position of the door, so you can see that there is light in the middle. The projection size is equivalent to a 50-inch TV size.
This is projected in the room, and the wall is opposite the window and there is no effect of pulling the curtains. More size, how to convert the projection size? I will not, anyway, a lot bigger than the aisle.
The effect of the night I did not shoot, but can refer to the effect of the study. Of course, the larger the size, the lighter brightness may be reduced.
There are some other features explained again next time. For now, if Cool Music is used at home as Q7, it feels that the frequency of use will not be too high. The main problem is the brightness. If it is to go out and take it, it is a good choice. After all, it is small and easy to carry. However, if you take the door out, you still have to protect yourself with a dust bag.
