What is the brand of portable power station supply

At present, this kind of products in China are mainly used for the basic power demand and protection during outdoor self-driving tours and camping (communications, photography and other digital products, basic boiling water and cooking, lighting), followed by the recent relatively hot economic and Emergency response to power outages with poor grid quality. Generally speaking, the domestic power grid is relatively good, and the emergency reserve market demand is small.　　

 

Outdoor camping, self-driving tours, basic power requirements and guarantees can be met by each product. See specifically how to choose. Outdoor travel, even in the era of LiFePo4 Battery prices, but the larger the battery capacity, the greater the weight and volume of the product. Big. If you choose the common electrical appliances at home, such as microwave ovens, induction cookers, kettles, and ovens, they are basically around 800W-3000W. Therefore, I personally do not recommend choosing a very large outdoor power supply, which is heavy and large. It is very impractical for people to cook outdoors. Because the weight of the battery is proportional to the capacity. Which outdoor portable power station supply battery capacity to choose is not enough, unless the RV, but the RV cannot reach some of our special camps, how to choose it, it is recommended to be 300-1000W, if you choose electrical appliances, you can consider this range Electric appliances with the same function, short-term cooking (such as hot rice, oven, barbecue tray), as for some outdoor long-term cooking, some energy-saving stoves can be selected, or gas tanks can be appropriately considered according to environmental requirements, and open flames should be paid attention to Applicability.

 

The following four typical brands have different technical routes: 　

1) Top New Energy (recommendation index: ★★★★★): After the transformation from mobile phone power bank, it entered the outdoor portable power station supply market earlier, invested more in marketing and promotion at home and abroad, and has strong product packaging marketing capabilities, which is well known to many people. The market share is relatively high; however, because the company is a marketing-oriented company, the product R&D investment is insufficient, and the product technology has no bright spots. For example, the inverter has no independent R&D capability, and the main inverter modules are purchased out of the The converter is hard-switching technology, with high loss, 90% inverter efficiency, 80-85% conversion efficiency of the whole machine; the whole machine generates a large amount of heat, at 15%-20%, and the plastic shell design cannot dissipate heat. It needs to cooperate with fans and A large number of heat dissipation holes dissipate heat, and the fan produces about 20-30 decibels of noise. The heat dissipation holes result in a low level of waterproof and dustproof. After long-term use, dust and water vapor will easily corrode the inside of the product, which has a certain degree of safety hazards and will reduce product life, especially slightly worse For environmental use, it is a typical consumer outdoor power supply, which can meet general outdoor power demand, and it is not suitable for people with higher experience requirements. Because the brand is well-known, the price is high, and the relative price-performance ratio is not very high.　　

 

2) Ecoflow (recommended index: ★★★): The products are mainly high-power 1000W+ power range (common power 1300W, 1800W), high-power home appliances are more suitable, using PCS two-way converter, charging faster, electronic research and development level Relatively good. The structural design needs to be strengthened. Many special-shaped structural designs are used, so there is a certain amount of waste in the internal space, resulting in a large volume and a heavy weight, which can hardly be lifted by a single person. It is suitable for fixed use by outdoor construction workers and not suitable for outdoor travelers. , Lightweight and portable demand. In addition, the heat dissipation of the fan with an engineering plastic casing also has problems with noise, dust and water vapor eroding the interior. Due to the high operating and management costs, the product pricing is relatively high, and the price/performance ratio is average.　　

 

3) Moving family (recommended index: ★★★★): Professional outdoor portable power station supplies, mainly products in the range of 300-1000w, technology-driven company, focusing on research and development. Using innovative inverter technology, the inverter efficiency is increased to 95%, the heat generation is reduced by half, and the alloy shell dissipates heat without the need for cooling holes and fans. The product experience is good, without any noise, the dustproof and waterproof level is higher than similar consumer-grade outdoor power supplies, IP52, due to the integrated design, the volume and weight are the best in the industry, and it is more suitable for users who require outdoor travel, portable, and high-quality experience. . Due to insufficient marketing investment, the current visibility is not high.　　

 

4) Goal Zero (recommendation index: ★★★): Domestically produced by foreign brands, the sales volume is not large, high-power around 1200W is the main profit point, the products are large in size, heavy in weight, and high in price. They are mainly sold in the US market. Summary: 　　 low-end inferior products: the same power price is very low, use B-type batteries, sheet metal shell, simply add BMS protection board and inverter, you can use it, it is a factory compatible model, due to its own battery quality and protection function It is not perfect enough, the risk of accidents is high, and safety issues should not be underestimated. It is not recommended to purchase if conditions permit. Well-known products: priced 2000-8000, relatively good quality consumer outdoor power supplies, such as Top New Energy and many other brands, but without special design, due to the large investment in product marketing, the price is high, the price is moderate, and it is suitable for outdoor use There are no special requirements, and those with good economic conditions can be purchased.　　Professional products with technical strength advantages: relatively strict product design, innovative inverter and LiFePo4 Battery management technology, such as: moving family, high efficiency, no fan, no noise, small and portable, professional outdoor power supply with high protection level. ECOFOLLOW high-power, fast-charging high-power outdoor power supply designed with bidirectional converter.　　Products with general popularity and no technical advantages: the price is 1000-3000, the products are diverse and diverse, and attract attention through appearance, basically plastic shell and mechanical fan heat dissipation structure, the same power and capacity are large, and the application characteristics are not clear.
