The cool box can be powered by a cigarette lighter adapter. These adapters are capable of 10 amps and the car is protected with a 10 amp fuse.
A 48 watt cool box draws 4 amps. 48 watts / 12 volts = 4 amps.
If the device drew more than 10 amps it would have to be connected to the car battery directly.
What else can I help you with?
What does plus 12V mean?
Plus twelve volts if you're in physics.
What would happen if you put a penny in an electrical outlet?
nothing as pennies do not fit into the wall outlets...they will however fit into CAR 12V ROUND outlets
Calculate the resistor in a circuit having 12V source voltage and power dissipation of 10 W?
0.069444444444444444444444444444444444 ohms. P/E^2=R. P = power in watts. E = electricity in volts. R = resistance in ohms.
How much current flows in 10 ohms when connected to 12 volts?
Ohms are the unit of resistance you find in Ohms LAw which says Volts = Amps x Ohms. You can get a voltage drop across a resistance, but would have to know what current is being used and you would have a potentiometer in effect. You are not "converting 12V" to 10V, your are essentially loosing two volts through a resistor.
Can you use a higher watt light bulb instead of a lower watt light bulb E.g. A lamp uses 9w light bulbs can I use a 13 watt one?
9w to 13w is not a big jump, but you need to check the fuse rating, which will have been chosen to limit the current to a safe level for the wiring, to see if the extra current is still within the fuse rating. Is this in an auto? If at 12v the current will rise from 0.75 amp to 1.08 amp. You should also check the lamp holder to see if there is a power limit stamped or printed on it.
Can a 12V 800MA adapter be used in place of a 12V 500 Ma adapter?
Yes
Can 12v 600 mA adapter replace 12v 1200mA adapter?
No, the replacement adapter has to be of an equal or greater value but never lower.
Where can you get a 12v 23va adapter?

Where can you find an adapter 12v 55va for fiber optic tree?
i need a 12V 55VA Adapter for my Christmas Tree where can i get one and quickly
Can 9V 1A adapter be used for 12V 1A speakers?
No. If it works at all, it will be underpowered, and possibly damage the speakers. To power 12V speakers, you have to have an adapter with EXACTLY 12V (no more, no less), and at least 1A. You could hook up a 12V 4A adapter if you wanted to, your speakers would just only draw 1A of power. Make sure you use a 12V adapter though!!
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
The main difference is the amount of current each power adapter can supply. The 12V DC 3A power adapter can provide up to 3 amps of current, which means it can power devices that require more current compared to the 12V DC 1.5A adapter. This can affect the compatibility and performance of devices connected to the adapters.
Can you use a 12v-0.6a 7.2va adaptor instead of a 12v 1.5a adaptor?
No, you cannot use a 12V 0.6A (7.2W) adapter instead of a 12V 1.5A adapter. The 0.6A adapter provides insufficient current for devices that require 1.5A, potentially leading to underperformance or damage to the device due to inadequate power supply. Always match the voltage and ensure the current rating of the adapter meets or exceeds the device's requirements.
Can a 12V 2A adapter be used for a 12V 500mA device?
The adapter's voltage must match that of the device, and its current-rating must exceed that of the device. So the answer is yes.
Can you use a 12V DC adapter for 5V DC device?
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.

Can I use 12V 1A adapter for a 12V 0.16A device?
I wouldn't recommend it ! If the device needs to draw more current than is available - the adapter could overheat, posing a fire risk.
What if you use a 12V 1.5mA power adapter in place of 12V 1.2 mA one?
It will take longer to charge the device
