　　Portable energy storage product is a built-in high energy density lithium-ion battery system that can provide a power supply system with stable AC/DC voltage output, which can be used in outdoor travel, emergency disaster preparedness and other scenarios. Compared with traditional small fuel generators, portable energy storage products have the advantages of safety, portability, green environmental protection, no noise, and easy operation. They can be widely used in outdoor leisure, operation, rescue and disaster relief and emergency backup.

　　In recent years, the overall demand environment for the outdoor portable energy storage market has been good. First of all, due to the impact of the new crown epidemic, the outdoor leisure time in developed markets such as Europe and the United States has increased significantly, resulting in an increasing demand for outdoor electricity. Secondly, the large proportion of wind and power stations portable is connected to the grid, which affects the stability of power supply. Emergency backup power has gradually become an important backup in family life in the United States, Japan and South Korea. Third, the emergence of portable energy storage fills the market gap of charging treasures and fuel engines: the charging capacity of conventional charging treasures on the market is below 0.4KWh, and the charging capacity of mainstream fuel generators is above 3KWh. Outdoor leisure sports, field work, small emergency backup power for families and other occasions have long been blank for the backup power supply of 0.5-2KWh, which is just filled by portable energy storage products.

　　Lithium batteries account for the highest proportion of portable energy storage costs, and are also a key factor in determining the service life and cost reduction speed of portable energy storage products. According to industry research, lithium batteries account for between 50% and 70% of the overall portable energy storage cost. It is estimated that the global demand for lithium batteries for portable energy storage will be 1.45GWh in 2022, and the global demand for portable energy storage lithium batteries in 2025. The volume is expected to exceed 15GWh.

　　At present, the entry threshold for mainstream energy storage products below 500W is relatively low, and the quality requirements for lithium batteries are general, so the market competition is fierce and the market concentration is low. Energy storage of more than 2KW will belong to high-end products with larger backup capacity in the future. It has higher requirements for product safety, battery thermal power management, etc., and has higher added value.

  

　　Choosing the right luggage is always not an easy job. There have been many innovations in material, design, and function over the years. Firstly, figure out if you want a softside or hardside luggage. If you’ve already found your way here, that means you’ve decided that a hardside luggage is your best bet.

　　Now for the next step: material. And there are two main materials you’ll find everywhere: Polycarbonate and ABS.

　　Polycarbonate vs. ABS

　　Polycarbonate and ABS are the most common types of plastic used in suitcases market. Polycarbonate is more flexible than ABS and has a higher impact resistance. As a result, it makes for a stronger suitcase. ABS suitcases are cheaper than Polycarbonate ones, but they are heavier and life is short.

　　Polycarbonate

　　Polycarbonate is an amorphous polymer (ie. plastic) with properties that make it ideal for hardside luggage. It has excellent transparency that means it is easy to make in different colors and patterns. It also has high degree of hardness and impact resistance making for durable luggage. Polycarbonate is also highly temperature resistant and has some nice self-extinguishing properties.

　　This also means it can be moulded pretty easily into different ABS+PC luggage shapes, making it very flexible and able to take a beating during travel.

　　Polycarbonate is also popular to use in luggage because it's so lightweight. It can bend and dent and will easily go back to its original shape. It is almost impossible to break and has the highest level of strength of all luggage materials.

　　ABS

　　ABS is a blend of three kinds of plastics, each with their own unique characteristics.

　　Acrylonitrile provides chemical and fatigue resistance, hardness, and melt strength.

　　Butadiene provides good impact resistance.

　　Styrene provides heat resistance, processability, color and hardness.

　　Together, ABS is great for impact resistance (ie. luggage handlers), easier processing (making into shapes) and has great mechanical properties: high heat distortion temperature, and gloss property.

　　This makes ABS ideal for a broad field of applications, including piping and fittings, instrument and appliance housings, tool housings such as hand drills, electric screw drivers, automotive instrument panels and home appliances.

　　In luggage, ABS is the cheapest hard material used. It's also very light and makes ABS luggage cheaper than most, but unfortunately it's also not the most durable. For most luggage makers, however, they use ABS combined with other materials to make a stronger suitcase overall.

　　Hongtu Weiye Luggage Co., Ltd offers you a complete solution for PC/ABS luggage equipment project.

　　Starting from Dryer blender-Extrusion line-Vacuum forming-CNC cutting-Sewing machine-Rivet machine-sewing machine-Assembly conveying line

　　And all related accessories like wheels , trolley, screws, hand rails, zippers, aluminum sash. etc.

  

　　When the driver gets out of the car, he opens the door without confirming whether the car is coming from behind, causing serious car accident injuries. Basically, most of these accidents are caused by the driver's negligence. It is undeniable that if everyone is more vigilant, it may also be possible to reduce accidents However when discussing the ratio of liability, we can actually make some changes to reduce the possibility of accidents and ensure everyone's driving safety, right?

　　During the installation process, in order to satisfy the overall texture after installation, the door panel must be disassembled during the process. It is recommended that you look for relevant precautions and disassembly points before operating the installation to avoid disassembling the wrong parts and damaging the door panel or trim panel. Most car door panels Most of the dismantling process has relevant information to find, just be patient to find it.

　　Operation point 1: No matter where the light bar is attached, it is strongly recommended that the location where the LED light bar is attached should be cleaned as much as possible without damaging the surrounding interior or car paint, so as to prevent the light bar from falling off.

　　Operation point 2: Install the LED light strips around the door. Based on the author's personal experience, the ceremonial lights on the original car door will be used for power connection. If the original car does not have this designer, it must be connected to the power supply from the inside of the car door light accessories.

　　Operation point 3: When installing modified items around the door, the most common disassembly is the door inner panel. During the disassembly process, remember not to forcefully disassemble it. Please confirm that each locking screw has been removed before proceeding with the disassembly.

　　Triangular window trim panel removal, most car door triangular windows have interior trim panels installed, the removal process does not require tools, just need to carefully confirm the foot position, and pull it out with one force.

　　When the door switch screws are removed, most cars will have some slight decoration inside the door, which makes people unable to find the screw position for a while. Before removing the door handle screw, pay more attention to find it.

　　The door armrest screws are removed. Of course, there will be screw locks in this position. Of course, there will be decorative panels covering the screws. You can find the location by searching carefully. However, the design of each car model is different.

　　After the door trim panel screws are removed, you can use your fingers or a special crowbar for the door trim panel to open the door trim panel. After pulling it open, push the door trim panel upwards to separate it from the door.

　　The door pull rope removes the linkage switch. The steel rope of the door must be removed at this time to facilitate subsequent follow-up operations. Because each car has a different design, if it cannot be removed, do not force it.

　　To facilitate the operation, it is strongly recommended to remove all switch wire groups on the door, so as to facilitate the rotation of the door trim panel, so as not to allow the wire groups to follow the winding and avoid damage to the wire groups.

　　Power supply wiring Most cars have door etiquette lights design, we can directly use the power supply here, but if not, we must pass through the door coil to connect the interior light power supply to the car.

　　Of course, for the convenience of dismantling the ceremonial light line group, you can freely choose whether to carry out this operation or not. If you do not carry out this operation, you must carry the door panel wiring operation.

　　Light bar connection test Because the LED light bar has positive and negative polarities, it is best to use a three-meter to confirm, but if you miss the preparation, you can also jump to confirm which line will operate normally.

　　After the power supply confirms which line is crossed, you can dial the line to cross, and some car owners do not like to destroy the original car.

　　When attaching the light bar, please be careful not to set it too high, otherwise it will be damaged by other parts of the door, and it will be a waste of effort!

　　After the light bar is confirmed to be attached, it is recommended to connect the power supply first and conduct a power-on actuation test. In addition to avoiding the occurrence of wrong installation, it can also confirm the effect of the light-emitting warning. If you are not satisfied, you can adjust it again.

　　After there is no problem in the storage test of the redundant wire group, the reserved wire group can be stored. We can use a small strap to tie the reserved wire group together and tighten it for future adjustment.

　　When the reassembly is completed, the previously disassembled wire sets and pull ropes must be reassembled one by one, and they must be properly installed, otherwise there will be a dilemma that the door cannot be opened in the car!

  

　　Cordless vacuum cleaners are a new type of vacuum cleaner that do not need a power cord to get the job done. Like a mobile phone, it uses a charger to keep the machine running. Generally, it takes 4-10 hours to complete the charging, and it can work continuously for 20-30 minutes.

　　The wireless vacuum cleaner has a built-in drive motor, turn on the vacuum cleaner switch to run the machine, and the wireless vacuum cleaner will clean according to the human drag, no power cord restraint, whether it is cleaning the ground, cleaning the gaps of doors and windows, or cleaning the car, it is very free

　　Since the wireless vacuum cleaner is a brand new type of vacuum cleaner, there are still some misunderstandings about the consumer's understanding of the wireless rechargeable handy vacuum cleaner
.

　　Myth 1: The suction power of wireless vacuum cleaners is very small, and the vacuuming effect is worse than that of traditional vacuum cleaners. Correction: The suction power of the wireless vacuum cleaner is completely comparable to that of the wired model. The wireless vacuum cleaner rotates at a high speed through the motor (the speed can reach the speed of the racing engine), which can provide a strong suction power, and even the stubborn dust can be sucked away.

　　Myth 2: The use time of a wireless vacuum cleaner is only a few minutes, which is not practical.

　　Correction: The wirealess vacuum cleaner keeps the machine running by charging the battery. The high-capacity batteray can avoid leakage and discharge, and the one-time use can last about 30 minutes.

　　  

　　

　　LEDs appeal to automakers and consumers for several reasons: they are brighter than halogen headlights and generally cast a wider pattern, and they use less energy, last longer, and are whiter than halogens, Halogen lamps are usually yellow. What's more, a lot of people think they look cool.

　　Halogen headlights have been the standard in the automotive industry for years because they are cheap to manufacture and easy to replace, but now LEDs outshine them.

　　Since hitting the road, automotive led lights for cars headlights
have changed the way manufacturers and drivers understand automotive lights. While LEDs may be slightly more expensive than halogens, LEDs last longer and have a higher light intensity of up to 12,000 lumens. This quality of light enables better visibility on the road, allowing drivers to stay safer on the road.

　　First things first: If you're switching, you want to know if LED lights are worth the money. Fortunately, a car's LED lights can last up to 20 years. This means you will rarely need to replace LED headlights compared to halogen lamps, which sometimes need to be replaced every year. The longevity of these lamps is partly due to their simple but sturdy construction. LEDs consist of a single unit that converts electricity into light, which is more efficient than halogen bulbs, which require more components and moving parts to function.

　　The LEDs have heat sinks that prevent the area through which current flows from heating up. Here's what makes sure you're looking for the best LED lights for your car: a poorly functioning radiator can do more damage to the entire car.

　　Here's how they differ: Halogen lamps are incandescent lamps with tungsten filaments inside the bulb. When current is passed through the filament, it heats up and produces light. They differ from regular incandescent bulbs in that they have a dose of halogen gas instead of argon. Halogen bulbs are brighter and last longer than regular incandescent bulbs.

　　With LEDs, current is passed through a semiconductor (or diode) to produce brighter light that produces less heat. LEDs work 90 percent more efficiently than incandescent bulbs, and because they generate less heat, this helps them last longer than other types of lights. LEDs also generally don't burn out like incandescent bulbs, although they do dim over time.

　　Because LEDs are smaller than bulb-type lamps, they offer greater design freedom for headlights and other vehicle lights. The downside is that they are more expensive than halogen or high-intensity discharge headlights that typically use xenon gas.
  

　　how do portable power stations work

　　Portable power stations are the smaller, lesser-known cousins of generators. They keep your power tools, phone and other electronics charged and running smoothly. These versatile, lunch-box-size power banks can go with you to construction sites, on camping trips or wherever else you need electricity. They're also useful backup power sources during a power outage when you need to keep your phone on or an essential appliance running.

　　Portable power stations can be a lifesaver in many situations. Whether you find yourself in a blackout with no backups or need to charge up some electronics while camping, this is an essential item for camping and home. We look at how portable power stations work and how to pick the best one fit for purpose.

　　A portable power station’s main component is a rechargeable battery. This battery stores charge and release it in DC form or AC form via its outputs. The outputs can include AC, USB, or Cigarette lighter plugs. A power station can be charged with either an AC charger or using solar panels. They are also referred to as solar generators.

　　Components of a Power Station

　　A power station is made up of different components. The main component is the battery with all the other components supporting functions either to charge the battery or power devices from the battery.

　　Battery

　　As stated before the main component of the power station is the rechargeable battery. Modern power stations consist mainly of lithium-ion batteries which are more stable, lighter, and can be recharged quicker and easier.

　　Inverters

　　Power in the battery is stored in the form of DC power. In order to use power from to power AC appliances which is most of the appliances in our homes like TVs, laptops or blenders you need to convert the power to AC power.

　　A power station will need an Inverters to convert DC power from a battery to AC current for household use. Inverters come in many different sizes and shapes, as well as with different features to suit their specific use. So the type and size of inverter in the power station will determine what devices it can power.

　　Charge Controllers

　　Since most power stations can be charged using a solar panel a Charge controller is a must. A charge controller is a device that regulates the input power from the solar panels into the battery to prevent overcharging.

　　It does this by checking the voltage of the battery and disconnecting the solar panels once the battery is fully charged. It is a critical component of a stand-alone solar system.

　　Battery Management System

　　A Battery Management System is vital in Lithium batteries. It’s a system that monitors things such as battery voltage, regulating when power is coming from the battery and when to charge it.

　　Inputs and Outputs

　　The inputs allow you to charge the battery and the outputs to charge or power your device. The inputs can include DC and AC inputs that allow you to charge the power station from a wall socket or solar panel. The outputs can include AC, USB or Cigarette lighter plugs to charge your phone, laptops and power your appliances.
  

　　In addition to the alkaline property of detergent, it will hurt the car, and the surfactant contained in it will also cause damage to the paint.

　　But not all surfactants have such a powerful power. Our commonly used shampoos and shower gels also contain surfactants. I have never heard that shower gels will hurt your body, right?

　　It seems that firecrackers will explode, but some firecrackers are so powerful that the mountains tremble and explode very loudly. Some of them are not so powerful. "Puff" the child laughs, and it doesn't matter if it is thrown on the ground and exploded.

　　This is mainly due to the use of milder surfactant ingredients in shampoos and shower gels, such as fatty alcohol phosphate salts, fatty alcohol polyether handheld automatic tire inflator, etc. The cleansing ability is weakened, but fortunately, it does not harm the skin.

　　The detergent that does not hurt your hands has the same principle. It uses a milder surfactant as the main masterbatch and adjusts the formula to minimize damage to the skin.

　　Therefore, the damage to the paint that also contains grease is less than that of ordinary cleaners.

　　It’s like rubbing your hands violently to remove the stuff on your face, but it may be very painful and red when rubbed. Now you get some water and wipe the dirty stuff off. The reason is the same. of.

　　The surfactant in the detergent that does not hurt your hands is gentler
  

　　At present, the common travel bags on the market are mainly divided into 20, 24, 28 inches and other specifications. If it is a short-distance domestic trip, it is recommended to use a size of 24 and below. If it is a long-distance or overseas trip, you should choose a large suitcase with a size of 28 inches or more.

　　But it should be noted that airlines have restrictions on the weight and size of hand luggage. It is generally required that the size of the luggage does not exceed 55cm×40cm×20cm, that is, a box under 21 inches, and it is allowed to board the plane within 5 kg.

　　The appearance of the luggage should be straight, without skew, sewing stitches are even and smooth, no burrs on the surface of the accessories, and the fixing parts and connecting parts should not be loose.

　　Leather fabric is the surface material, the appearance of the luggage should be free of obvious disability, no cracking, no cracking phenomenon;

　　artificial leather, synthetic leather materials are surface materials, the appearance of the luggage should be clear with a clear pattern, no bubbles, and print lines;

　　If the fabric material is the surface material, the main parts of the surface of the bag should be free of defects such as broken warp, broken weft, yarn skipping, and cracks.

　　Trolleys, wheels, and handles are frequently used due to load-bearing reasons, so they should be used as key inspection parts.

　　The standard does not need to bend when the pull rod is pulled, and it stretches smoothly without jamming;

　　Inspecting the walking wheels, you can put the box upside down, make the wheels leave the ground, and turn them by hand to make them idling, and observe whether the rotation is flexible;

　　The plastic of the handle needs to be soft and comfortable to hold, so as not to break during use.

　　Finally, remind consumers that it is best to buy leather Hard shell luggage sets and leather goods from regular channel brand vendors, not only the quality are guaranteed, the follow-up after-sales and maintenance services can also be more effective, and the first purchase voucher is kept as much as possible to avoid unnecessary dispute.

　　
  

　　Vehicle air pumps are also called inflators, air pumps, and air pumps, and they work through the operation of an internal motor. Principle: When the motor is running, the valve of the communicating device is opened by the atmospheric pressure, and the gas enters the cylinder, and when the tire is pumped, the valve is closed by the air pressure in the cylinder, and the gas enters the tire, which is considered to be used. The principle of atmospheric pressure is used to inflate cars, rubber balls, and rubber boats.

　　The air pump should be placed in a dry place, not in contact with rain, snow, and other liquids to prevent electric shock; at the same time, the air pump cannot be used continuously for more than 15 minutes, and it can be used again after it has cooled.

　　At the same time, be sure to pull up the car to brake before use, and block the wheel to prevent it from sliding; and because the transmission pressure can reach 100 Pa, the user should avoid over-inflating the tire and explode, as long as the number on the barometer reaches the charged object The recommended air pressure is sufficient.

　　This type of portable car refilling pump portable tyre pump only be used in small cars, and buses and large trucks cannot be used to prevent insufficient pressure and cause danger.

　　
  

　　Prednisone is approved by FDA in 1955, whereas Methylprednisolone is FDA approved in 1957.

　　Prednisone brand names include Rayos, whereas Methylprednisolone brand names include Medrol, Depo-Medrol, and Solu-Medrol.

　　Prednisone is available in the form of an oral tablet and oral liquid form, whereas Methylprednisolone is available in oral tablet and injectable form.

　　Prednisone is less strong when compared to Methylprednisolone.

　　Prednisone is an anti-inflammatory and immunosuppressant medication, whereas Methylprednisolone is used to prevent the release of substances that cause inflammation.

　　Prednisone causes side effects when taken in an improper manner side effects include damage of adrenal and pituitary gland functioning, whereas Methylprednisolone causes suppression of hypothalamic adrenal pituitary axis when taken in long term more than prescribed.
