I have a laptop which has an adapter input 100- 240v 50-60Hz 1.7A
Output 20v 3.25A
Can anyone tell me what size amp goes in the plug that you plug into the wall socket, i have 3 plugs 1 has 3amp fuse 1 a 5amp, and 1 a 13amp. Please help

The correct amperage is 3 amps. the input means the actual electricity coming in the adaptor, which in ur case is approx. ~220V 1.7A......the output means the actual electricity coming out of ur adaptor towards the laptop which is 20V 3.25 amps... My personal recommendation for you is to use the 3amps, because 0.25 A is not of that great importance....u always have to allow plus, minus 0.42 amps around the actual reading given by the books. But if you put 5 amps this is 1.75A larger and it is going beyond those 0.42 A and u'll definitely blow ur laptop out

you are right in your thinking, unlike boris, 5 amp for a washing machine, er no. A washing machine has a heater that draws around 10 amps. Also a fuse is designed to protect the cable too. Suppose you have an Appliance on an extension lead, the lead is rated at 5 Amp, but a 13 A fuse is in the plug, the appliance has a 3 amp fuse, the extension cable gets damaged. What goes first? The appliance fuse wont because the extension lead is damaged. The extension lead plug wont go as its 13 A The extension lead itself should melt and catch fire as its only rated at 5 amp

Ah, yes. OK, if you look closely you will see you have answered your own question.
100-240v 50-60hz 1.7A
The maximum the adapter will draw is 1.7 amp. Don't worry about the output, your concern is the input voltage, the part that you plug into the wall.around the world
Also, this adapter is designed to run off the mains current no matter where you are in the world, and no matter what voltage they have available.
Oh, right, the fuse. Use the 3 amp.

This question makes a whole lto of no sense, as long as the voltage and polarity are correct the current rating is irrelevant because the laptop will only pull the power it needs. If the input current is 1.7 amps at 120 you need to use a 1.7 amp fuse higher and you risk a fire lower a lot lower and you will be changing fuses a whole lot.

As a practical security measure one should not use a fuse or circuit breaker rated at more than 1.75 times the rated current of the charge. Under discussion now, the charge is the adapter. It is rated at 1.7 ampere. So the maximum current rating of the fusible should be1.7x1.75 ampere which is equal to 2.298 ampere. A fuse of 3 ampere will be quite adequate here. The type of circuit used inside the adapter should be known for a detailed analysis.

You should use about double of your current consumption which is 1.7A x 2= 3.4 A. So use 3 A plug for higher degree of protection. Output 20 V , 3.25 A is for the laptop.

Fit a 3 amp fuse (red) for appliances up to 720 watts

you should always use the smallest value possible (in this case 3A) a fuse is a safety device for protecting the equipment being used. No damage can come to the equipment with a fuse to small only to the fuse itself but a fuse to big will not protect the equipment

I have straighteners which is a 5 amp and my adaptor is 13 amp, can I still plug it in ?

3 amp ! You are drawing 1. 7 amps.
Output is nor relevant
