How big is the recommended outdoor power supply

Generally speaking, if it is a short-term camping trip and only charging a few small devices such as mobile phones and cameras, a 500 - 1000Wh capacity outdoor power supply can meet the requirements; for long-term outdoor operations, group travel, or scenarios that require driving electric ovens, drones, etc., with high-power equipment, it is recommended to choose a large-capacity product of 1000Wh or above.
