The capacity of the 800 mA adapter is 200 mA larger than the 600 mA adapter.
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
Worry about the voltage type and sign more than the mA. If the specs are right on target, you probably could. If not, not.
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
When sizing power sources, you must match voltage (which you have done) and make sure the supply can supply enough current to the electronics. If your supply is the 800mA, and the equipment using this needs 2500mA, then the power supply is undersized. If the supply is the 2500mA and the user is 800mA, then your power supply is oversized, and will work just fine.
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
All power adapters have to match the Wattage, Voltage and Amps exactly. So you have to look on the adapter on both of the power adapters and see if they match. If you use a power adapter that has more power than is needed you will fry the motherboard so be carefull. The wattage, voltage and amps are on the adapter..
Yes you can. All the 1300 mA rating means is that adaptor can supply devices up to 1300 mA. The old adaptor's limit was 800 mA. The new adapter has 500 mA more in reserve if it is ever needed.
The Magnetic DC is not a vital component of the Apple Power Adapter. Rather, it is a guiding mechanism, that helps guide the plug into the jack for a more secure connection.
It's very risky to connect a power adapter from other models. There are at least two choices, you have burned power control in your laptop or you have burned the power adapter (it might get to hot and then it turns itself off).
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!!
You give it more volts and it will burn out something!!
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
