How to choose outdoor power supply? Mainly from several aspects to consider:
1. Battery capacity: It is recommended to choose a large-capacity outdoor power supply to avoid repeated charging. Of course, the price is relatively higher.
2. Output power: When buying a power supply, you must know the power or battery capacity of the device to be loaded, so that you can know which power supply to buy and whether it can drive it.
3. Batteries: The main consideration when buying a power supply is also the battery. The battery can realize over-current protection, over-charge protection, over-discharge protection, short-circuit protection, over-power protection, over-temperature protection, etc. A good battery has a long life and excellent performance. Stable and safe.
There are three types of batteries for outdoor power supplies: ternary lithium batteries, lithium iron phosphate batteries, and lithium polymer batteries, all of which are currently mainstream lithium batteries.
4. Charging method: when the power supply is idle, the way to charge the power supply: the general power supply has three charging methods: mains power, car charger, and solar panel charging. You can choose according to your needs.
5. Diversity of output functions: AC, DC, car charging port, DC round port, USB, Type-C fast charging, wireless charging, lighting and other functions can be selected according to the needs.
In contrast, the lithium iron phosphate battery has a longer service life, and the lithium iron phosphate battery is used for a long time, there will be no danger of battery swelling and explosion, and it can be stably discharged when encountering bumps and impacts, and the safety is also higher. When purchasing, it is recommended that you give priority to the outdoor power supply of lithium iron phosphate batteries. (Very important: the general price of this kind of battery is also higher, but the safety factor is also better!
Compared with ordinary mobile power supplies, the outdoor power supply has the biggest feature: it supports 220V AC, and the high-power outdoor power supply is not a problem for camping and cooking outdoors. It can even charge electric vehicles. It is a fully functional and powerful Portable "power station". Of course, in household scenarios, in the event of a temporary or sudden power outage, the outdoor power supply can output continuous and stable power to maintain the normal power consumption of the equipment. Lighting, cooking, and office work are not a problem.
