There are also various power supplies emerging in the market. Many people are not familiar with this type of niche product and don’t know how to buy it. Below we mainly provide reference for purchasing outdoor power supplies from multiple aspects. With the improvement of quality of life and the diversification of lifestyles, outdoor travel and self-driving tours are becoming more and more popular among people.
1. Battery capacity
Battery capacity is the first thing to consider. At present, the battery capacity of outdoor power supplies in the domestic market ranges from 100Wh to 2400Wh, 1000Wh=1 kilowatt-hour of electricity. For high-power devices, the battery capacity determines the battery life and how long it can be charged. For low-power devices, the battery capacity determines how many times it can be charged and the power consumption. If you travel for a long distance, especially when you go to a sparsely populated place, it is recommended to choose a large-capacity outdoor power supply to avoid repeated charging.
2. Output power
The output power is mainly rated power, currently there are 100W, 300W, 500W, 1000W, 1800W, etc. The output power determines what electronic devices can carry. Therefore, when buying a power supply, you must know the power or battery capacity of the device to carry to know which power supply to buy and whether it can be carried.
3. Battery cell
The main consideration for buying a power supply is the battery cell. The battery cell is the storage part of this power supply battery. The quality of the battery directly determines the quality of the battery, and the quality of the battery determines the quality of the power supply. The battery cell can realize overcurrent protection, overcharge protection, overdischarge protection, short circuit protection, overpower protection, overtemperature protection, etc. A good battery cell has a long life, stable performance and safe performance.
4. Charging method
When the power supply is idle, the power supply is charged: general power supply has three charging methods: mains, car charging, and solar panel charging.
5. diversity of output functions
Districted into AC (AC) and DC (DC) output according to the current direction. The outdoor power supply on the market differs in the category, quantity and output power of the output port.
The current output ports are:
AC output: equipment used to charge computers, fans and other national standard triangle sockets and flat-head sockets.
DC output: Except for AC output, the rest are DC output. For example: car charging , USB, Type-C, wireless charging and other interfaces.
Car charging port: used to charge various car-mounted equipment, such as car rice cooker, car refrigerator , car vacuum cleaner , etc.
DC circular port: router and other equipment.
USB interface: electronic devices used for charging fans, juicers and other USB interfaces.
Type-C fast charging: Fast charging technology is also a technology that the charger industry pays more and more attention to.
Wireless charging: This is mainly aimed at mobile phones with wireless charging function. It charges as soon as it is released, and there is no need for a charging cable and charging head, which is more convenient and simpler.
Pure sine wave output: comparable to the mains power supply, stable waveform, no damage to the power supply equipment, safe and secure.
Weight volume: Based on the current energy storage technology , the volume and weight of the power supply with the same capacity are very different. Of course, whoever can reduce the size and weight first is the commanding heights of the energy storage field.
