## What does output 12V 1A mean?

12V 1A, means it can provide the current of 0A to 1A. while maintaining it’s 12V. After 1A, the voltage is not guarantee. For the current rating on the product, it indicate the maximum current the product will draws from it’s power supply.

## What does input and output mean on AC adapter?

The INPUT is what sort of electrical system you need to supply to the adapter (i.e. what your power company supplies). The OUTPUT is what is supplied to your device. Note that he amount of DC electrical power is calculated by multiplying the current by the voltage (P=I·V).

What does input 220V Mean?

As a general rule, when the adater says input X volts that means that its input is X volts. In the case of your adapter, x=110, meaning you should not plug it into a European outlet, which is 220V. The adapter you bought is made for taking European equipment to the US, not the other way around.

What is a 12 volt output?

In general, a 12VDC output is obtained from a 120VAC or 240VAC input using a combination of transformers, diodes and transistors. 12V power supplies can be of two types: 12V regulated power supplies, and 12V unregulated power supplies.

### Is 1000ma the same as 1A?

There is no difference. Mili is a subunit which totals 1/1000 of the main unit, thus 1000 mA = 1A.

### Can I use 1.5 amp instead of 1 amp?

No, amps do not have to match, but the power supply or charger must be able to supply enough amps as required by the device being powered or charged.

What does it mean input 100 240V?

When the voltage reading is listed as a range of numbers, like 110V–220V or 100-240V, the device can handle AC voltage outlets from all over the world. This is considered a “dual voltage” or “world-wide voltage” device.

What are input and output voltages?

The inputs are a supply and a demand in the system and the outputs are a supply and a demand in the system. The output voltage is the receiver part.

#### What is the difference between 220V and 240V?

In North America, the terms 220V, 230V, and 240V all refer to the same system voltage level. However, 208V refers to a different system voltage level. In North America, the utility companies are required to deliver split phase 240VAC for residential use.

What is an electrical input output?

Input​ refers to the amount of energy put into a device, and ​ output​ refers to the amount of energy that comes out. A device may change the type of energy but not the amount. For example, a light bulb’s input energy is the form of electrical energy, and its output energy is in the form of light and heat. Efficiency.
