Disadvantages of Outdoor power supply

1. Hidden dangers of charging safety, three reasons, the protection function of the battery battery B.Please select regular products with regular channels to stay away from low -cost and inferior products.

2. Large volume and not easy to carry.Some brands have launched high-frequency resonance technology, which can effectively reduce 30%-50%of volume.

3. The shell is fragile, using engineering plastic, collision, falling, fragmented, many miscellaneous cards and some big names also have this problem.

4. Heating, low inverter efficiency, and then using engineering plastic shells. The heat dissipation is poor. It has to open a lot of heat dissipation holes to increase fan cooling, high noise, and dust water vapor erosion products, leading to hidden safety hazards and reducing product life.

5. The cost performance is low. Some big -name advertising investment and high operating costs have led to high prices and low energy products. It costs thousands of yuan, but the power and power are not enough. The brand chooses to choose a medium brand, and the cost performance is relatively high.

6. Parameters are deficient or chaotic. Some products are deficient in batteries, which are more common in low -cost inferior products. Some products have launched high -power but very small -capacity products to attract people.battery, reduce costs.

1. What is the difference between color -changing Cycling glasses and polarizing Cycling glasses

There are many types of Cycling glasses. The mainstream is two types of color -changing Riding glasses and polarizing Cycling glasses. What is the difference between these two Cycling glasses?The difference between Cycling glasses and polarization is mainly:

1. Different principles

Trimous glasses are made by the principle of decomposition of halogen silver. When absorbing ultraviolet rays, silver and silver decomposition, silver atom and ultraviolet rays, the light transmission rate of glasses changes, and the color changes; polarizers are based on the polarization principle of light.When it is made, when the vibration plane of the light is parallel to the polarized shaft, the polarized light filter can make the polarization light through.

2. Different performance colors

The color changing glasses will be darkened when the sun is exposed, and the color will be restored when there is no strong light when entering the room; polarizing glasses generally will not change the color with the sun.

3. Different degrees of blocking light

Discounted glasses can only reduce the intensity of glare, ultraviolet light, and cannot completely block these harmful light; Polarized glasses can completely block the dazzling glare caused by various factors such as scattering, flexion, and reflection.

The above is the main difference between the two Cycling glasses. So which is the best color -changing mirror and polarizing mirror?

2. Choose polarized light or discoloration of Riding glasses

Riding glasses are one of the essential equipment for cycling movements. Some riders think that polarizing Cycling glasses is better, and some riders prefer to change color ride glasses. So is it good for Riding glasses to change color?

Generally speaking, the two types of Cycling glasses have their own benefits. Polarized Riding glasses can filter the UVA and UVCs of the sun, and can filter the water surface and glass reflex light from special angles such as cycling strabismus, which is suitable for the water under the sun.Ride on the road with many cars; and the color -changing Cycling glasses can change with the changes in ultraviolet rays and temperature in the environment, thereby protecting our eyes, but the filtering effect of ultraviolet rays is not as good as polarizing Cycling glasses, and it does not have it.The polarizing function is relatively better.

However, for conditional riders, it is better to prepare a pair of Polarized glasses and a pair of colorful glasses. You can also buy the ride glasses that can replace the lens and prepare two lenses.
