The title "Prada 220V" is inherently misleading. There's no such thing as a "Prada 220V" product. The confusion likely stems from a blending of two distinct concepts: the power requirements of a device operating at 220V (common in many parts of the world), and the unrelated luxury brand Prada. This article will address the electrical calculations presented regarding 220V power, focusing on the context of a Toyota Prado's power system, and then delve into the unrelated topic of Prada products and online shopping.
Understanding the 220V Power Calculation and Prado Power Sockets
The initial statement, "If 100 watts/220V = 0.45 Amps," is correct based on Ohm's Law (Power = Voltage x Current). A 100-watt device operating at 220V will draw approximately 0.45 Amps. However, the subsequent statement, "then the power cable from the inverter to battery has to rated to draw 100 watts of 12V which is 8.3 Amps," introduces a crucial element – power inversion.
This calculation assumes the use of a power inverter, a device that converts 12V DC power (typically from a car battery) to 120V or 220V AC power. The key here is that while the *output* power remains 100 watts, the *input* power will be significantly higher due to inefficiencies in the conversion process. Inverter efficiency typically ranges from 80% to 90%. Therefore, to deliver 100 watts at 220V, the inverter will need to draw more than 100 watts from the 12V battery.
Let's calculate the approximate 12V draw, assuming an 85% efficient inverter:
* Power output (220V): 100 watts
* Power input (12V) = Power output / Efficiency = 100 watts / 0.85 ≈ 117.6 watts
* Current draw (12V) = Power input / Voltage = 117.6 watts / 12V ≈ 9.8 Amps
This means a 10-amp fuse or circuit in a Toyota Prado would likely be insufficient to power a 100-watt 220V device via an inverter. The 10-amp, 120-watt rating mentioned likely refers to the maximum continuous current the socket can safely handle, not the power output of the device it’s powering. The power output of the socket is limited by the capacity of the vehicle's electrical system. Attempting to draw more than the rated current could damage the vehicle's electrical system or even cause a fire.
