1 Density "Ning small, not big"Some drivers believe that the higher the electrolyte density, the lower the discharge degree of the battery, the higher the terminal voltage of the battery, the greater the charging capacity, and can prevent the electrolyte from freezing in winter, and can freeze the battery to regulate electrolysis. In the liquid density, not only the density of the original...

First, understand the rating of the jump starterMany jump starter bag manufacturers use industry-recognized rating terms, while some other jump starter bag manufacturers use marketing terminology. If you really want to compare Apple to Apple, you must use a comparison level based on industry standard terminology. The meaning of the terms is as follows: Peak Ampere-Peak Ampere is a market term....

An air compressor is a machine that is heavily used in many industries that require compressed air. The machine is designed to generate kinetic energy and can be used for various applications, such as pneumatic tires or powering pneumatic tools. There are different air compressors on the market, and each compressor has a specific configuration and specifications. Like many other heavy machines...

A compressed air tank or "carrying tank" is a convenient workshop or garage tool that allows you to store compressed air in a portable, easy-to-use device. You can use any type of air compressor to fill compressed air into the storage tank, and then transport the storage tank to where it is needed. Compressed air tanks are most commonly used to fill tires (in cars, bicycles, trailers, ATVs,...

There are many variations of jump starters: car jump starters, heavy jump starters... all our models are portable jump starters. Our two heaviest battery boosters are equipped with wheels to make your life as easy as possible. Peak amps (PA) and starting amps (CA) are the most important characteristics of choosing the correct jump starter. What is the difference between peak amps and starting...

Modern emergency lighting is installed in almost every commercial and high-occupancy residential building. The lamp consists of one or more incandescent bulbs or one or more high-intensity light-emitting diodes (LEDs). Emergency lighting lamps are usually PAR 36 sealed beams or wedge-shaped base lamps. All units have some kind of equipment to focus and enhance the light they produce. It can be...

Lighting plays an important role in modern buildings, and LED and fluorescent lights are potential choices for builders. Although the cost of fluorescent lamps is lower, the maintenance costs of LEDs are reduced, the heat emitted is less, the toxins are free, and the energy consumption is lower. These features make LED lights very suitable for emergency lighting. LED also has the advantage of...

Spotlight is electricIn the most basic form, the spotlight is the basic circuit. The power source (depending on the spotlight model, which can be AC ​​or DC) is connected to the high-intensity bulb through a switch. When the switch is moved to the "on" position, the mechanism inside the switch completes the circuit and allows current to flow from the power supply through the lamp and back to...

Most fire emergency lights use dry lead-acid batteries. Lead-acid battery (VRLA) is a storage battery whose electrodes are mainly made of lead and its oxides, and the electrolysis solution is sulfuric acid solution. In the discharged state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the...
