How to Choose An Outdoor Power Station
The outdoor power station is a large power bank. What we often use to charge our mobile phones is a small power bank - small and delicate, even smaller than a mobile phone;
The medium-sized power bank used to charge the laptop is larger than the mobile phone power bank, and the battery capacity is also higher.
However, if you go out camping, barbecues, and, picnics, the battery capacity of small and medium-sized power banks is not enough. At this time, you need a large-capacity power bank that can charge a variety of devices. At this time, the outdoor power station will take advantage of the trend.
If you give a precise definition, the outdoor power station is:
A device that allows you to safely use electricity anytime, anywhere outdoors.
A portable power station that can hold enormous amounts of energy.
A device that will keep you away from power shortage panics in areas outside the city, where there are no electrical outlets.
What parameters should be paid attention to before purchasing?
Outdoor power supplies and UPS uninterruptible power supplies have a lot in common, mainly focusing on two points: one is battery capacity, and the other is power.
The battery is the core of these power station devices, and the capacity of the battery determines how long it can keep outputting power and how long it can provide battery life.
Considering that the outdoor power station can be placed in the trunk of the car, the volume does not need to be a priority, so if the size does not matter, try to choose a power station of 500Wh or more.
Power represents the wattage W, which is different from the watt-hour Wh and the milliamp mAh. The wattage represents the output power of the outdoor power station. To drive a lot of electronic equipment, it is recommended to choose an outdoor power station of more than 500W.
Except for a few electronic devices such as UPS, which use lead-acid batteries, most of them use lithium batteries. The same is true for outdoor power supplies, which are lithium batteries.
Most of the current outdoor power station cells are cylindrical lithium-ion cells 18650 lithium batteries, also known as ternary lithium batteries; there are also lithium iron phosphate batteries.
These two kinds of lithium batteries are relatively mainstream lithium batteries.
The ternary lithium battery has many advantages, including high battery density, and large energy output, but poor high-temperature stability, not as safe as lithium iron phosphate battery.
Compared with ternary lithium batteries, lithium iron phosphate batteries are safer and have better charge and discharge performance, but the battery density is low.
These two kinds of lithium batteries have their advantages, but for an outdoor power station, you don't need to care about which kind of battery.
Outdoor power supplies are generally used outdoors or in vehicles. It is inevitable that they will be bumped, dropped, squeezed, and even bumped and rolled in extreme cases. In order to protect the lithium battery cells inside, there must be a sturdy casing.
Static electricity will inevitably be generated during travel, and static electricity will pose a fatal threat to the circuit in the outdoor power station, and the metal casing is naturally anti-static.
To sum up, the combination of aluminum alloy + ABS & fireproof PC plastic becomes the most ideal choice for the heat dissipation, sturdiness, anti-static, and lightness of the aluminum alloy shell.
