1·How to choose the right parameters?
①outdoor short-term digital applications, cell phones, tablets, cameras, notebooks and other outdoor office photography crowd, small power 400-600w, power 300-500wh products can meet.
②outdoor long-term travel, boil some water, cook a meal, a large number of digital, night lighting, audio needs, it is recommended that the power 1000-2000w, power 500-1008 products can meet the demand.
③family emergency power outage, lighting, cell phone digital, notebook, induction cooker, rice cooker, refrigerator, fan 1000W-3000w can be, depending on the actual needs.
④outdoor work, no utility simple construction work, it is recommended that more than 3000w, more than 2000wh can meet the general operational needs.
2·What points should we pay attention
①charging safety hazards, three reasons, B battery+ battery protection is not perfect and no fault-tolerant technology + charge management without fault-tolerant technology. Please choose the regular channels of regular products, away from low-priced low-quality products.
②large size, not easy to carry. Some brands have introduced high-frequency resonance technology, which can effectively reduce the volume by 30%-50%.
③the shell is fragile, the use of engineering plastic, collision, fall fragile.
④heat, inverter efficiency is low, and then also use engineering plastic shell, poor heat dissipation, had to open a large number of cooling holes, increase the fan cooling, noise, and dust and water vapor erosion of the product's internal circuitry, leading to safety hazards as well as reduce the life of the product.
⑤low cost-effective, some of the big brand advertising investment, high operating costs, resulting in high-priced low-energy products, spend a few thousand dollars, but the power and power are not enough, the brand choice can choose the lower and middle brands, relatively high cost-effective.
(6)parameter false labeling or confusion with, part of the product battery false labeling, mostly seen in low-priced low-quality products, there are also part of the product in order to attract people's attention, the introduction of high-power but with a very small capacity of the product, to be used as a high-powered products to sell, reduce the battery, reduce the cost.
