What is the Difference Between an Outdoor Power and a Power Bank?

Outdoor power supply, actually called outdoor mobile power supply, is equivalent to a portable charging station. The main feature is the configuration of various types of output ports:

1. 1.USB, TypeC, can charge general digital devices.
2. The car charger interface can charge the car battery or supply power to other on-board equipment.
3. Support 220V AC output, which is equivalent to using mains power at home.

What's the difference between a power bank and a power bank?

1. Output power

At present, the mobile phone charging treasures on the market have a relatively large output power of 22.5W. The power bank for laptops can reach 45-50W.

The outdoor power supply starts at 200W, most brands are above 500W, and the maximum can be above 2000W.

High power means that high-power electrical appliances can be used.

2. Capacity

Before comparing the capacity, I have to introduce the unit to you.

The unit of the power bank is mAh (milliamp-hour), which is generally referred to as mAh.
The unit for outdoor power is Wh (watt-hour).
Why is there such a difference?

1. Because the output voltage of the power bank is relatively small, the output voltage of the mobile phone power bank is 3.6V, which is the same as the working voltage of the mobile phone.

It is also because of the voltage problem. If you want to use the power bank to charge the notebook computer (working voltage 19V), you have to buy a special notebook computer.

2. The unit of Wh actually refers to power consumption or capacity, which you may not have seen. But when I say this, everyone gets a bit of an impression:

1000Wh = 1kWh = 1 kWh.

The conversion formula of these 2 units: W (work, unit Wh) = U (voltage, unit V) * Q (charge, unit Ah)

Therefore, a 20000mAh mobile phone power bank has a capacity of 3.6V * 20Ah = 72Wh.

Generally, the outdoor power supply capacity is at least 300Wh. This is the capacity gap.
