Choose high-quality portable UPS outdoor mobile power supply

How to buy high-quality portable UPS outdoor portable power supply? How to choose high-quality portable UPS field power supply? With the development of society and the development of science and technology, field portable UPS mobile energy storage power supply has been more and more widely used. Portable UPS is small in size, light in weight and easy to use. It is a necessary backup energy storage product for outdoor activities. This article teaches us how to choose high-quality portable UPS on-site mobile power supplies. How to choose a high-quality portable UPS on-site power supply? 1. Preliminary acceptance and brand Before purchasing a portable UPS on-site portable power supply, it is necessary to consider several issues, combined with our own requirements: specific use, use location, whether it takes a short time Emergency or long-term travel. Suppose it is an emergency charging, and a relatively small product needs to be picked up. This product is convenient to carry and can make calls while charging, but the battery capacity is relatively small. If you use it on site for a long time, you need some large-capacity products. This product has large specifications and is inconvenient to carry. Of course, on the subway or train, there are also some medium-sized, fashionable products that may be good choices. Regarding the choice of mobile power brand in the field of portable UPS, I think I want to choose a brand with excellent quality and outstanding image. Haobo battery portable UPS brand is very good. 2. Try to choose a well-known brand brand building to be advertising, but also word-of-mouth. Choose a well-known brand of portable UPS mobile power supply, the processing quality may be better, and the future after-sales service is now in place. 3. Selection of energy storage medium The primary batteries used in portable UPS power supplies include nickel-metal hydride batteries, lithium iron phosphate batteries, liquid lithium batteries and lithium polymer batteries. The last two important things are marketing. You cannot choose to use the first two batteries. The output power of these two batteries is very low, and there is no benefit. Don't buy them. Liquid lithium batteries and lithium polymer batteries have relatively stable output power, especially lithium polymer batteries and liquid lithium batteries have the characteristics of light weight, safety, and high efficiency. 4. The appearance and weight of the product require different types of power banks to be selected according to the usage conditions. For emergency use, a small portable UPS mobile power supply should be selected, and a large-capacity mobile power supply should be selected for the backup power supply. Regarding products with the same functions, you should check and choose products that are light in weight and easy to carry. 5. Product compatibility Mobile phone and other types of electronic products are complicated to process, circuit planning and interfaces are different, the same mobile power supply is not suitable for all electronic products, so it is necessary to know the interface and voltage required by electronic products before buying And other information. Assuming you can inspect, take the counter to the inspection machine. Generally speaking, the charging voltage and current of a mobile phone is 5V1A. Assuming that your mobile phone is very special, it should have a merchant interface. 6. Confession conversion rate The conversion rate of the portable UPS power supply is very important. If the conversion rate is too low, it means that the line loss of the mobile power supply will be very large, which may lead to the danger of heat generation or even explosion. Consider evaluating the conversion rate of each mobile power model. Chen said that if the ad claims that the conversion rate exceeds 90%, it may be a mistake. Generally, products with a conversion rate of around 85% are now very good. 7. Product accessories and additional functions Although the important function of UPS mobile power is charging, some additional functions will bring us more benefits. For example, there are multiple charging adapters that can be amplified, dual ports can charge two electronic devices at the same time, and LED lighting can be used in emergency situations. In addition, some mobile power sources also have solar charging functions. This is actually a chicken rib. Because many users find that solar charging is almost impossible, the charging time is too long. 8. Battery capacity Generally, the capacity of a battery is proportional to the volume, the larger the volume, the greater the capacity. Try to choose products with large capacity and the same capacity. 9. Protection parameters Portable UPS power supply should have protection measures such as overvoltage, overcurrent, and undervoltage.
