Can I use 65w charger for 45w?
Yes, that’s right. Wattage is a measurement of how much power a supply can provide. If your computer requires 45w, but your power supply can provide 65w, you will be fine.
Can you put a plug on a transformer?
Do not site the transformer on surfaces which are easily scratched, stained or damaged by heat. Either plug it in or have a qualified electrician connect it to a suitable supply. extension lead – though you can, of course, plug extension leads into the transformers’ socket outlets.
Are laptop Chargers dual voltage?
Many common persovonal devices–like an iPhone charger, laptops, and cameras–that people like to travel with can be easily powered up abroad with a simple plug adapter because they are dual voltage devices.
Can you use a 90W charger on a 45W?
So these will all be the same voltage and the amperage will be diferent to get higher watts (w = v x a). The important thing is the volts and the plug. If they are the same, as you say, you can use a higher watt adapter but not a lower so the 90w will work.
Can you plug a 110V transformer into an extension cord?
An extension cord should never be used between the transformer and the electrical outlet. Plug the transformer directly into the power outlet. Low voltage outdoor lighting is not hard to install or maintain.
How are step up and down transformers used?
Step-up/Down transformers are used to convert electricity from 220V/240V AC to 110/120 V AC (step down) or 110V/120V AC to 220V/240V AC (Step-up). These type of transformers are grounded and with build-in fuses, which provides safety against electrical shock and damage. 4) How do I figure out how many watts voltage transformer do i need?
Do you need a plug adapter or transformer?
(You can look at your power adapter, like the one above, to double check.) That means wherever you go, you probably only need to use plug adapters. There’s one notable exception: hair things.
Can you use a 130 watt power supply with a 65 watt laptop?

The short answer is that you may be able to use that 130-watt power supply with your new machine, which came with a 65-watt supply, if a couple of conditions are met.
Can a transformer be used to change local voltage?
In those cases, you can use a transformer to change the local voltage into the one your appliance expects, but I advise: don’t. There are a lot of voltage transformers out there. None of them get particularly good reviews.
