There are actually three pieces to this puzzle - resistance. And you're missing that one.
If you have to ask this question, you shouldn't be dealing with 11,000V
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.

Some simple 3 terminal single chip linear regulators are:+5V - 7805, LM309, LM323-5V - 7905, LM320Some high efficiency single chip switching regulators are: +5V - LM2574-5.0, LT1076-5-5V - LT3015-5Note: always read the datasheet carefully to make sure a part meets the requirements of your application before designing around the part.
assuming 5v steady the 2 amps can be virtual zero by reducing the load present
Well, trying to clarify your question, if you have a device that normally has a 5V 3.6A adapter, than it likely needs to be able to draw up to 3.6 amps or so for the device to operate normally. So, a 5V 2.6 amp adapter may operate at times, but only when the device is trying to draw less than 2.6 amps. If the device tries to draw more than 2.6 amps than you run the chance of burning out your transformer (the AC adapter), or just not having your device work. Both adapters will put out the 5 volts, but the 2.6 amp adapter will not provide enough current. You can safely use a larger adapter than the 3.6A, as your device will only draw as much current at 5 volts as it needs. On another note, do not try an adapter that puts out the same current but more voltage. Such as 7.5 volts 3.6 amps. This will overdrive your device and potentially burn it out.
Depending on the application and other factors, it will TYPICALLY be best to use a transformer. If it's a low current application, you can purchase a small 5V power supply transformer for under $20.00, US.

The amps you can run off a 5-volt charger depend on its power rating, which is usually indicated on the charger itself. Most 5V chargers come with a specific amp output capacity (like 1A, 2A, or 3A), which tells you the maximum current it can safely supply. To determine how much current you can draw, check the charger's label for its maximum amp rating. Exceeding this limit can cause overheating, potential damage, or trigger safety features that shut it down. For example, a 5V, 2A charger can safely provide up to 2 amps, which is 10 watts of power (5V x 2A = 10W). If you need more amps, you’ll need a charger rated for a higher current at 5 volts.
There's a 12V and a 5V supply. The 5V is for the logic. The 12V supply is for the motor.
A 5V 2A charger outputs 10 watts of power.
