Portable power stations energy storage battery

  The applicability of batteries can be compared from the following main aspects: safety performance, design life, operating temperature, maintenance cost, recyclability.


  (1) Safety performance: Among the sodium-sulfur batteries, flow batteries, lead-acid batteries, lithium iron phosphate batteries and power capacitor batteries, the power capacitor batteries use inorganic electrolytes, which will not burn and explode by themselves. The authoritative test results show that the power capacitor battery has passed the safety tests such as extrusion, acupuncture, short circuit, heating and vibration, and the battery does not burn or explode.


  (2) Design life: The power capacitor battery has no "memory effect". Its nominal cycle life is 10,000 charges and discharges. Under the actual driving conditions of the bus, it has been cycled more than 28,000 times, and the product is normal; a smart machine in a Shenzhen company uses a power capacitor battery to complete 200A/20 seconds high-current rapid charging more than 127,000 times, and the product has no abnormality.


  (3) Operating temperature: The operating temperature of the power stations for camping capacitor battery is -40 to +55 °C, so it can be used in most parts of the world. The operating temperature index is especially important when used in northern my country. Lithium batteries are designed to operate at a temperature of 10~50°C and cannot be used in cold areas.


  (4) Maintenance cost: The operation and maintenance cost of the power capacitor battery is very low.


  (5) Recyclability: The power capacitor battery is rich in rare resources such as rare earth elements and nickel compounds. One ton of batteries contains 300-350Kg of rare earth and 350-400Kg of nickel, and the recovery rate is higher than 90%. The manufacturer guarantees recycling, and the recycling value is not less than 10% of the sales price. In the process of battery use, the recycling and dynamic reserve of rare resources such as rare earth and nickel are realized.

Best handheld vacuum cleaners for spot cleaning

  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 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 rechargeable handy vacuum cleaner.


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


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

The reason why shopping carts are getting bigger

  You enter shopping supermarket with a couple things on your list: paper towels and shampoo. The next thing you know, two hours have passed, your cart is completely full and the cashier just told you your bill is over $200. We’ve all had this shopping experience before. What happened? Lack of self-control? Temporary insanity? Oddly enough, the size of the shopping cart might be at least partially to blame for your over-spending—at Target and everywhere else.


  Shopping Carts Are Bigger Than Ever


  One of the very first shopping carts, invented in 1937, was simply a metal frame that held two wire shopping baskets. Eventually the design evolved to one basket, and the nesting capability was added for easy storage. The first shopping cart baby seats were added in the 1950s. For the next several decades, the shopping cart design remained the same—except when it came to size. The average shopping cart has almost tripled in size since 1975. From a stack of two hand baskets to the gigantic carts we see today, why the change?


  Bigger Carts Lead to More Spending


  There are a couple of theories out there as to why shopping carts have gotten bigger and bigger: wider shopping aisles and larger shopping budgets are leading people to buy more goods and groceries. But there could be a more subliminal reason: to trick the consumer into spending more. that when the Shopping Trolley Carts cart was doubled in size in an experiment, shoppers would buy 40% more merchandise.


  Check out these tips for saving money at the grocery store.


  Skip the Cart to Avoid Overspending


  So how do you stop overspending at shopping supermarket? First of all, skip the giant cart. Grab a basket, or go without any carrier at all.
