1. What is Portable Power Station
An outdoor multi-functional power supply based on lithium-ion batteries, which can output USB, USB-C, DC, AC, car cigarette lighter and other common power interfaces. Covering all kinds of digital devices, household appliances, and car emergency appliances, providing backup power for outdoor travel and family emergency. At the same time, solar power storage can be used for a long time in areas away from mains power.
2. How to choose the parameters that suit you
①For outdoor short-term digital applications, mobile phones, tablets, cameras, notebooks and other outdoor office photographers, products with a low power of 300-500w and a power of 80000-130000mAh (300-500wh) can meet the requirements.
②For long-term outdoor travel, boil some water, cook a meal, a lot of digital, night lighting, audio needs, the recommended power is 500-1000, and the power 130000-300000mAh (500-1000wh) products can meet the needs.
③, home power failure emergency, lighting, mobile digital, notebook, 300W-1000w can be used, depending on actual needs.
④ For outdoor work and simple construction work without mains power, it is recommended to use more than 1000w, and more than 270000mah (1000wh) can meet the needs of general low-power operations.
3. The current pain points of purchasing Portable Power Station
①, Potential charging safety hazards, three reasons, product B battery + battery protection function is not perfect and has no fault-tolerant technology + charging management has no fault-tolerant technology. Please choose regular products from regular channels and stay away from low-priced and inferior products.
②, bulky, not easy to carry. Some brands have introduced high-frequency resonance technology, which can effectively reduce the volume by 30%-50%.
③, the shell is fragile, using engineering plastics, it is easy to break when collided and dropped, and many miscellaneous brands and some big brands also have this problem.
④, high heat generation, low inverter efficiency, and the use of engineering plastic shells, poor heat dissipation, had to open a large number of heat dissipation holes, increase fan heat dissipation, high noise, and dust and water vapor erode the internal circuit of the product, resulting in potential safety hazards and shortened product life.
⑤. Low cost performance. Some big brands have large advertising investment and high operating costs, resulting in high prices and low energy consumption. They cost thousands of yuan, but the power and power are not enough. Brand selection can choose middle brands, which are relatively cost-effective.
⑥ False parameters or confusing collocations. Some products have false battery labels, which are more common in low-priced and low-quality products. In order to attract attention, some products have launched high-power but very small-capacity products to be sold as high-end products, reducing Batteries, lower costs.
4. Recommended by several major brands (in no particular order)
①Dian Xiao Er (recommended index, 80 points)
Advantages: focus on marketing and brand promotion, high market share, and fashionable product appearance. Disadvantages: Insufficient investment in research and development, relatively backward electronic software technology, relatively short charging speed and inverter technology, and the plastic shell is matched with low-efficiency inverter, so a large number of cooling holes and fans have to be opened to dissipate heat, the noise is too loud, and dust and water vapor are easy to erode Inside, there are certain security risks. The brand is big, the price is high, and the price/performance ratio is relatively low.
②Migration (recommendation index, 89 points)
Advantages: R & D-driven brand, focusing on professional-level Portable Power Station, the first brand to use high-frequency resonance technology inverters, has a great advantage in size, the same specification is 40-60% smaller than its peers, and the resonance technology has high efficiency. With the heat dissipation of the alloy shell, it has achieved zero noise and a fully enclosed structure, which relatively improves safety and prolongs service life. Disadvantages: Low popularity, insufficient marketing investment, few product categories, relatively complicated process, and low production capacity.
③ecoflow, (recommendation index, 83 points)
Advantages: focus on the field of fast charging, use high-power charging technology, the charging speed of the product is faster, which is its biggest feature. Disadvantages: the inverter efficiency is medium, and the engineering plastic shell needs to be matched with a fan, which causes noise and dust and water vapor erosion, and the internal A large number of special-shaped structure designs, the volume is too large, and the weight is too heavy.
④Other small and medium-sized brands, (recommendation index, 75 points)
Advantages: low price, many types of products, disadvantages: mixed, battery quality, protection board, charging management, depending on the brand, there will be a very big difference. Worry about potential safety hazards.
5. Normal specifications and price range
300W capacity not less than 80000mah 1300-1800 yuan
500w capacity not less than 130000mah 2000-2400 yuan
600w capacity not less than 145000mah 2500-2800 yuan
1000w capacity not less than 260000mah 3500-4200 yuan
6. Precautions for purchasing
1. Select the capacity and power segment according to the usage requirements, and focus on the two parameters of capacity and power. Don’t just look at the power, you will be slaughtered.
2. Choose the brand according to the budget, large, medium and small brands.
3. It is best to choose cost-effective products based on professional knowledge, not blindly follow the trend, and choose the one that suits you.
4. Don't be greedy for cheap, the lowest price will sometimes make you pay the highest "cost", the price of blood
