High voltage low amp adaptor you have the original power adapter for your laptop The output rating for the ac adapter is 19v 3.42A you have a replacement that has a 30v and 2.5ACan you use it?

No. Two reasons.... It is a much higher voltage (30V) and will destroy your laptop. Even if the Volts were correct (19), the Amps aren't sufficient... The original can output much more than the replacement. If the laptop needs 3.42A (which it likely does) a 2.5A just isn't going to have enough umph to power it.

Can I use a 9 Volt 1 Amp power adaptor in place of a 5 volt 1.2 Amp adaptor?
No, the voltage of the replacement adapter must always be IDENTICAL to the original adapter and the current of the replacement adapter must be the same or larger than the original adapter.Trying to use a 9 Volt adapter to replace a 5 Volt adapter will almost certainly completely destroy the device the moment you plug it in.You did not say whether the adapters provided AC or DC or the polarity if DC. Either way both the replacement adapter and the original adapter must be IDENTICAL in this respect.
High voltage low amp adaptor I have the original power adapter for my laptop. The output rating for the ac adapter is 19v 3.42A. I have a replacement that has a 30v and 2.5A.Can i use it.?
NO!!!!! Find a charger with the same voltage!! If not, you will fry your battery. The only electrical number you can go higher on is the milliwats.

No. It might work (you've sufficient power to get the thing working) but the extra current demans from your laptop will cause the adaptor to get hot... really hot. Although alot of adaptors have a thermal cutout it's not wise to depend on it and a fire would really ruin your day.
Can a 9 volt adaptor be used on a appliance that calls for 9volt battery or 12volt adaptor?
No. The person who designed your appliance had a 12v adapter, so when he designed the adapter connector he put a resistor in it to drop the voltage to 9v.
Can you use any 220 volt adaptor on a 110 volt appliance?
No. 220V adaptor can't control the output voltage, 110V appliance will be fry. Use instrument transformer or voltage regulator instead.
You have an acdc adaptor but you dont know what its for?
Check the output voltage and mA capacity on the nameplate of the adaptor. The adapter will be useful on devices at that DC voltage and up to the mA capacity of the adaptor E.g. the nameplate may read Input: AC120 volts 5 watts. Output: DC 12 volts 200 mA.
If you buy a replacement battery for a laptop but has a different voltage do you buy a new adapter as well?
no
What is an adaptor and how is it used?
An adapter, depending on what device your using it for connects that device to the internet or a network.
Ac Adapter is it ok to use higher voltage?
On both the primary side and the secondary side the answer is no. It's OK if the voltage is within 10% of your original AC Adapter.
Is it ok to use a 5v 1A AC adapter for a device when the original adapter is supposed to be 5V 500mA - will it damage the device?
Yes - what matters is the voltage - it has to be the same. The device will only draws 1A as needed - the adaptor with higher amp,i.e, 2A is fine. As long as the adaptor has amps equal to or greater than those of the device, it will be ok!
Will a device requiring AC DC 9V 1000mA work with an adapter that provides 1250mA?
Yes, an adaptor with a capacity of 1250 mA's will run devices that are rated up to and including 1250 mA. Always check that the voltage from the adapter matches the device.
The original 4V adapter that came with a cordless phone burned out. Can you use a 6V adapter instead?
With caution - yes. The higher voltage shouldn't cause any harm to the phone - due to circuitry built into the phone to 'smooth out' the voltage from the original charger. However - don't leave it connected for long periods once it's charged. It will take less time to charge the battery (due to the higher voltage). I've used 'replacement' chargers with phones in the past without any problems.
