1. How high power is the best power for Outdoor power

The output power of Outdoor power supply is generally 250W, 500W, 600W, 1000W, 1100W, 1800W, 2200W, etc. The greater the power, the more electronic equipment that can be powered, and the richer the content of outdoor activities.The power selection of Outdoor power supply needs to be determined based on the power size of the equipment, the scene, and the length of use.

1. Short-term digital applications for Outdoor Outdoor: mobile office photography groups such as mobile phones, tablets, cameras, laptops, etc., choose products with a small power of 300-500W, and the power within 1000Wh (1 degree).

2. Outdoor travel or self-driving travel: there are boiling water, cooking, a large number of digital, night lighting, audio entertainment, the recommended power of 1000-2000W, and the electricity of 2000WH-3000WH (2-3 degrees) products can meet the needs.

3. Family power outage, in addition to lighting and digital power consumption, may also need to drive home appliances. It is recommended to at 1000W, or it depends on the power of the electrical appliances at home.

4. Outdoor operation, construction operations without municipal electricity. The recommended power is above 2000W and the power is above 2000Wh. In this way, the configuration can basically meet the general low power operation requirements.

2. How to choose Outdoor power supply

1. Capacity

The capacity of Outdoor power supply is the first indicator that we need to consider when purchasing.Is that the larger the capacity, the better?Of course not, it depends on the personal situation.

The Outdoor power supply from 500W to 600W has a battery capacity of about 500Wh to about 600WH. It is almost 150,000 mAh. It can supply about 100W equipment for about 4-5 hours. 300W equipment is about 1.7 hours such as rice cookers.Second-rate.

The Outdoor power supply of 1000W-1200W has a battery capacity of about 1000Wh, which is almost 280,000 mA. It can supply about 100W equipment for about 7-8 hours. The 300W equipment can be powered for about 2-3 hours. The mobile phone can charge more than 60 times.

The Outdoor power supply of 1500-2200W has a battery capacity of about 2000Wh, which is almost 550,000 mA. It can supply about 100W equipment for about 15 hours. The 300W equipment is about 5-6 hours. The mobile phone can charge more than 100-150 times.

2. Power

The power of Outdoor power determines what equipment can be used.For example, if you want to cook outdoors and use home appliances such as rice cookers, microwave ovens, refrigerators, air conditioners, etc., it is necessary to have a high power Outdoor power supply, otherwise the power supply will trigger self -protection and cannot supply normal power.

3. Output interface

(1) AC output: 220V AC (double plug, three inserts) output interface, has compatibility compatible with municipal electricity, waveform is the same pure -string wave as the municipal electricity, which can be like electric fans, hot kettle, rice cooker, microwave oven, refrigerator, refrigerator, refrigerator, refrigerator,, Electric Diamond, Electric Povery and other home appliances and common electric motor equipment.

(2) DC output: 12V 5521 DC output interface is an interface that effectively outputs a fixed voltage after the input voltage, which is usually used for laptops and tablets.In addition, there are 12V cigarettes, which can provide electricity support for vehicle equipment.

(3) USB output: The age of fast charge to pay attention to speed and efficiency is too important. Ordinary USBs are 5V output, but now there are more and more Outdoor power.The USB-C output port with 60W PD fast charging, of which USB-A can charge electronic devices such as mobile phones, while USB-C can meet the power requirements of most office laptops.

4. Charging method

If the charging method is actually the better, the most common is the city power charging, but when traveling outdoors, there is not a chance to charging the city power, and the time for charging is not short. Then you can use the car to use the car.Charging, even charging with Solar panels, and absorbing solar energy on the roof. It can be fully used in a few hours. At night, the electric energy reserved by Solar panels can be used, which is convenient and electricity.

5. security

The battery cells on the market are divided into two types, one is the 18650 lithium battery and the other is a lithium iron phosphate battery.The 18650 lithium battery is similar to the No. 5 battery that I usually see. It can be seen in various electronics products. The stability and compatibility are very good, but the number of cycles is low.Short point.Lithium iron phosphate has a long life, has higher peace of mind, supports fast charging, has a wide range of working scope, does not include any heavy metals and rare metals, green and environmentally friendly.

What are the classification of polarizing mirror

1. According to use

skiing mirror: You don't have to worry about reflective and ultraviolet rays, you can skate it;

fishing mirror: The water wave shines under the sun, but you will not feel uncomfortable at all, but feel comfortable and easy;

Polarized driving mirror: no more reflective troubles from the sun and the vehicles in front of the vehicle;

outdoor sports mirror: During vacation, let you enjoy the sun, beach and leisure time;

golf glasses: Don't worry about the dazzling sunlight, let you perform golf skills on the lawn.

2. According to the material

glass material: Hardness is high, scratches are not easy to appear, the impact resistance is poor, it is easy to break after being impacted, and the weight is heavier.

Resin material: very light, high -temperature resistant, resistance to impact, and can effectively block ultraviolet rays and see things clearer.

TAC lens material: effectively reduce strong light, the vision is clearer and soft, clear, will not be distorted or dizzy of the wearer.

3. According to the principle

Round polarizer (referred to as CPL)

Linear polarizer (referred to as LPL)

LPL is mainly used for old -fashioned manual focus cameras.The late CPL adds a layer of 1/4 wavelength film. This film has a special nature that can generate /2 phase shifts in one direction (assuming X) polarizing electrical vector, and vertically with it to be vertical with itThe electrical vector of the direction (assuming to y) has no effect.Therefore, the direction of the angle level of the above polarized light along X and Y can pass through 1/4 waves, so the light of the outlet is that there are two polarizing directions perpendicular to the light, and the polarized light of the phase difference /2 is synthesized, which is so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -calledThe round is biased.This design makes it more suitable for new automatic focus and automatic exposure cameras.The camera currently using AF lens (switching camera lens with automatic focus function) uses CPL as polarizing mirrors.Under some light conditions, a linear polarizer may mislead the light metering element in the aircraft to merge, so the DC and most automatic focus cameras use round polarizers.

4. Press color

Light red or vermilion: In the case of glare, it can deepen the contrast and sharpness, which is very suitable for water activities and snow activities.

Brown or brown: It can enhance the contrast of color, so it becomes the first lens when driving.

Amber, yellow or orange: It is very suitable for wearing in cloudy days. It can have a very clear field of vision, but it is not suitable for strong use in the sun.

Gray or dark green: It can maintain the most natural original color when visually, which is a good choice.

What are the characteristics of all types of polarizing mirrors

According to the different mechanism of filter polarization, polarizers can be divided into two types: round polarizer (CPL) and linear polarizer (LPL). These two functions are the same.LPL is mainly used for old -fashioned manual focus cameras.The late CPL adds a layer of 1/4 wavelength film. This film has a special nature that can generate /2 phase shifts in one direction (assuming X) polarizing electrical vector, and vertically with it to be vertical with itThe electrical vector of the direction (assuming to y) has no effect.Therefore, the direction of the angle level of the above polarized light along X and Y through the direction of the lines of X and Y can pass through 1/4 waves, so the outlet of the light is that there are two polarizing directions perpendicular to the light, and the polarized light of the phase difference /2 is synthesized, which is so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -called so -calledThe round is biased.This design makes it more suitable for new automatic focus and automatic exposure cameras.The camera currently using AF lens (switching camera lens with automatic focus function) uses CPL as polarizing mirrors.Under some light conditions, a linear polarizer may mislead the light metering element in the aircraft to merge, so the DC and most automatic focus cameras use round polarizers.

The role of the PL mirror is to filter reflective light to increase the contrast of imaging.Its working principle is to selectively filter light from a certain direction.By filtering the many biased Lights in the long reflection, weaken the intensity of light in the sky, darke the sky, and increase the contrast between the blue sky and the white clouds.When you shoot the specific real shooting, you should look at the viewfinder and rotate the front mirror. The darkest effect in the sky in the viewfinder is the most obvious, and the darkest is 90 degrees.You can transfer to any angle of the darkest and the brightest rooms as needed.

PL mirrors can also effectively weaken or eliminate non -metallic surface reflection. This reflection light is a typical polarizing light (the light reflected by the metal surface reflection is not polarized light, and the Polarized mirror does not work on it). By adjusting the polarizer, you can filter it by adjusting the mirror.The reflection of this part is dropped, thereby improving the image quality of the subject and improving the clarity of the picture.For example, by using polarizers, the reflection of the water surface can be weakened to clearly shoot the fish in the water.When shooting such a scene, the projection angle of the light source should be consistent with the angle of the camera, and its maximum partial angle needs to be agreed between 30 and 40 degrees.When using it, you can adjust the lens in the front group of the filter to minimize the reflection on the surface of the scene.

In addition, polarizing mirrors can effectively improve the saturation of color and increase contrast. This is because polarizing mirrors can absorb various directions reflected by fog or dust reflected in the atmosphere, so that the shooting images are more pure.For example, in photography such as flowers and static objects, polarizers are often used to take colorful photos.It is useful when landscape photography, flower photography and shooting certain specific reflective scenes.The polarizer is used in the landscape photo, and the depiction of the cloud layer has excellent effects.The light refractive index of the blue sky is greater than the light scattered by the white clouds.Using polarizer can also make the color of green leaves more saturated and eliminate the fog of shooting urban scenery at low angles.

Is the color change lens good for the eyes?

1. Graylens

Absorbing infrared rays and 98%ultraviolet rays.The great benefit of gray lens is that the original color of the scene is not changed due to the lens, and it is satisfactory that it can effectively reduce the strength of the light.Gray lenses can be absorbed balanced with any chromatography, so watching the scene will only darker, but there will be no obvious color difference, showing the real and natural feeling.It belongs to the neutral color system, which is in line with the use of all people.

2. Tea -colored lenses

It can absorb 100%ultraviolet rays. Tea -colored lenses can filter out a large amount of blue light and improve visual contrast and clarity, so they are popular with wearers.Especially when air pollution is severe or fog, it is better to wear.Generally, the reflective light on the Smooth and bright surface can be blocked. Those who wear glasses can still see the minor part, which is an ideal choice for the driver.For middle -aged and elderly patients with high vision above 600 degrees, it can be given priority.

3. Green lens

Green lenses can effectively absorb infrared light and 99%ultraviolet rays as gray lenses.While absorbing the light, it increases the green light of the eyes to the eyes, so it has a cool and comfortable feeling, suitable for people who are easy to fatigue with the eyes.

4. Pink lens

This is a very common color.It can absorb 95%of ultraviolet rays.If it is a glasses that correct the vision, the ladies who must wear them often use light red lenses. Because the light red lens has a good absorption function on ultraviolet rays, and it can reduce the overall light strong, so the wearer feels more comfortable.

5. Yellow lens

It can absorb 100%ultraviolet rays, and allows infrared rays and 83%visible light penetration lenses.The large feature of yellow lenses is that most of the blue light is absorbed.Because when the sunlight is too atmospheric, it is mainly expressed in blue light.After the yellow lens absorbs the blue light, it can make the scenery of nature more clear. Therefore, yellow lenses are often used as a "filter", or hunters are used when hunting.

Who is not suitable for color change mirrors

1. Patriotic patients

It is not advisable to work or read for a long time in the dark. Although the discolored Sunglasses are light under the natural light, it still has a great impact on its vision.Eyemirror.

2. People with high myopia and hyperopia

Taking light white slices when choosing a lens.Because the refractiveness is too high and the color of the color transformer mirror is inconsistent, it will affect the clearness of the vision. Therefore, those with high myopia or high -profile vision should not wear a color transformer.

[Character fabric] What kind of assault clothing fabric?

Which fabric is good?

Choose the charge fabric

Everyone knows that good charge fabrics can not only reflect the overall design and novel styles, but also fully consider the external environment and occasions wearing.Let s teach you the 5 techniques of the screening and purchase of the fabrics of the jacket:

1. Because the jacket must be completely waterproof, the seam must be used to prevent the pins from leaking with hot pressure strips. Carefully see if the rubber bar in the clothes is flat and whether there is a bubble.The seams of the car are all crushed with waterproof rubber strips, ensuring excellent waterproof characteristics.

2. Whether the hem of the clothes has a windproof skirt or not, if there is no windproof skirt, you can tighten the clothes, and the drawing rope at the hem to prevent the snow from being poured into the body from the hem in a harsh environment.

3. Whether there is a breathable zipper under the armpit of the clothes.Not all assault jackets will have this design. There are ventilated zippers under the armpits, which is very useful in harsh environments or in large amounts of exercise.

4. Whether the tightening method of the cuffs is appropriate?The magic sticker design at the cuffs can be adjusted and loose at will according to different body types.

5. Whether the hat can cover the wind and rain well, whether the activity of the back head is free.If you use activities such as ice climbing and snow mountain climbing, you must also consider the activities after wearing a helmet.It is fully considered that the comfort of the wearer and the convenience during exercise can be removed from the three -dimensional design of the unloading hat and have multiple adjustable functions.

Selection and use of fabrics during the production process -physical properties.

1. Strong scrape: It can produce a stable modeling effect. The stiff fabric has a physical expansion, and it has no extra pleats and accumulation to make clothes. The design of A and H in the design is the most appropriate.To judge the stiffness of the fabric, you can simply put a small piece of fabric on the edge of the table to let it hang down naturally. The jacket made of the fabric in the red line will be more stylish

2. Feeling: It is comfortable to feel. It is not recommended to be too hard and too astringent. Especially the products sold in the mall, the customer's taste of customers consume is high.In terms of feel, nylon fabrics are better than polyester fabrics.Everyone's feel is different. The training feel is to touch more, touch the fabric of the famous factory, and touch the fabric of the first -line charge brand.

3. Anti -wrinkle: Punching sleeves and backs are frequent with tables and chairs, and the fabric is required to have high anti -wrinkle resistance.Rub the fabric samples hard, and then Smooth it. Look at the degree of wrinkles disappearing. The fabrics without wrinkles or a small amount of wrinkles have good anti -wrinkles.In addition, listen to the sound when rubbing, do not have rustling fabrics, because when wearing the clothes made by the fabric, you can hear you from 10 meters away.

4. The relationship between yarn and density: Now the punching clothes are pursuing lightweight, and the fabrics with thin, gauze chips, and high density are required;Wrinkles; good fabrics are mechanical indicators such as the feel, stiffness and anti -wrinkle resistance of the fabric by increasing the number of F numbers as much as possible, appropriately increased the twist, and increase the density.Therefore, when picking the fabric, you must go to the F number and twist data as much as possible.(F is the number of single gauze roots. The larger the single veil, the finer, the better the flexibility of the yarn, the better the feel will feel)

5. Organization/pattern/flower color: Chunya Textiles, Tatson, polyester tower, grid, and diagonal lines are commonly used classic fabrics, flat but enduring; pay attention to use small bistanic fabrics, and make good designs with good taste.Teacher to choose, people have their own good, tastes not representing the candidates of the public, they are easy to fall into the custom, and they will be reduced to street goods by accident.With buds, novel things can be available to attract consumers' attention, but to control the proportion appropriately, Jobs's realm is simplicity.

6. Thick thin: thin spring and summer, thick autumn and winter; don't affect the effect of glue pressure, thickness cannot make the clothes too bulky; the number of scrapers of the waterproof coating has a lot of impact on the thickness of the fabrics;Essence

7. elasticity: Properly use elastic fabrics on the back of the elbow, which can be a gimmick of ergonomics in the whole point, but if you use elastic fabrics for whole clothes, it depends on whether you can sell it.), Especially the fabric with spandex; the mechanical bullet is easy to collapse after washing; the elastic modulus should not be too small (the minimum power of the deformation of the fabric), otherwise it is easy to wrinkle when pressing the glue;Below temperature water

8. color saturation: It is relatively fresh and positive. In contrast, there will be a feeling of bright eyes.The saturation is very related to the hardness of dyes and water quality. Clariant's dye and auxiliary performance is very good. It is specified for some first -line varieties. South Korea and Taiwan's water quality helps color saturation (industry legend).color has great influence on attracting customers into the store and purchasing.If the clothing is combined, pay attention to the water -washing and sticky color of the first and second colors. The polyester materials are easy to stick to each other.

The production process of the jacket

1. Types of coating and film: The feel of the finished fabric is basically a film & gt; wet coating & gt;However, it is not environmentally friendly; 2.5L and 3L fabrics are currently from famous factories, otherwise it is easy to produce quality problems, and the rubber strip is responsible for matching the fabric factory.The problem of water washing rate in the middle and noodles caused the fabric to wrinkle; which test method must be specified in waterproof and breathable parameters, and it is strictly tested. In addition, it is best to do aging testing. Many new domestic in China have a lot of new domestic tests.The imitation coating has cracked turtle after washing the water many times, and the functions are lost.

2. ingredients: Tear and feel nylon are better than polyester. There is a good factory polyester fabric; recently, there are leisure brands with waterproof and breathable trench coats with all cotton tables;Sticky color.

3. The thickness of the yarn branch: In the case of the unchanged D also, the number of F numbers is required to increase the furniture of the fabrics, such as the same thickness wire rope, which will definitely be soft in the fine steel wire inside.

4. After finishing: The surface cloth is easy to dip the dust (especially the black); the natural luster of the chemical fiber is very low, and it should be treated as much as possible;Affect water washing rate, etc.

1. How long can the fishing nets use

The general situation is 1.5-3 years.

If the maintenance is better, it will be better, it depends on how many times you use, and whether you will maintain it. This is very important.Generally, the fishing nets caught the fish. When you get the fish, you must pay attention not to cut the Fishing Net. If you are not careful today, you will be careless tomorrow.

2. What are the maintenance methods of fishing nets

The Fishing Net is a consumable. After learning the correct preservation method, the next time you want to use it, you will still be brand new as yesterday.

1. Whether it is nylon net or polyethylene network, the resistance to ultraviolet rays is very low. For a long time, the sun will appear in the sun. Therefore, after the Fishing Net is usedSave in a cool and ventilated place.

2. After the fishing nets are used, they must be cleaned first to remove attachments such as sludge and fish greasy.

3, sun net, you should avoid direct sun exposure, choose spacious, ventilated, and dry places for drying.It should be noted that the fishing nets after drying should not be placed directly on the ground, but should be placed on a rack or so on the wooden box of about half a meter from the ground.The place where placed should be kept ventilated and dry, and the door should be closed tightly like a rainy day to prevent the Fishing Net from moisture.

4. At the same time, the fishing nets should prevent rats, insects, etc. in storage, and do a good job of preventing mice and insects. There should be no other volatile and corrosive chemicals where the fishing nets are stored.
