Can we use a 12v 1A instead of 12v 0.5 A?

Can we use a 12v 1A instead of 12v 0.5 A?

CocaCola said: Unless you look at the bottom of the router in question and see that it actually only requires 0.5A (500mA) or less input… In that case it will work…

Can I use a 12v 1A adapter with a 12v 0.5 A power rated modem?

4 Answers. You cannot use that adapter because it is outputting more voltage than the original (12v vs. The new adapter must have the same tip polarity.

Can I use 12v 1A instead of 12v2a?

Yes. You can use same volt with 10009000000AMP Power supply on that. but not 20V with 1A Power supply. Yes.

Can I use 1A power supply for 0.5 a device?

The amperage rating of a charger or power supply is the maximum it can supply. A device being charged will only take as much amperage as it requires. If your device needs 0.5 amps to charge, and your charger is rated at 1.0 amps, only 0.5 amps will be used. The device being charged may be damaged.

Can I use a 1A charger for a 2A device?

It is perfectly safe to plug a device that draws 1A into the 2A port and vice versa. Amperes are a measure of current capacity. The current draw (Amperes) is controlled by the device you plug in. So if you plug a 1A device into a 2A charger, it will still only draw 1A.

How do you make a 12V 1A power supply?

List of components of the 12V power 1A supply circuit

1. 1 NPN TIP41C or TIP41A bipolar transistor (Q1)
2. 1 NPN 2N3904 bipolar transistor (Q2)
3. 2 1N5400 rectifier diodes (D1, D2)
4. 1 1N4742 zener diode (12V) (D3)
5. 1 10K, 1/4 w resistor (R1)
6. 1 0.5 ohms, 2w resistor (R2)
7. 1 2200 uF / 35V electrolytic capacitor (C1)

Can I use 2A charger for 1A?

If you plug a 2A device into a 1A charger, you will only get 1A. The device will charge more slowly (1/2 speed roughly) but everything will be fine. see less It is perfectly safe to plug a device that draws 1A into the 2A port and vice versa. So if you plug a 1A device into a 2A charger, it will still only draw 1A.

Can you use 12V adapter for 10v?

Can I use 12v/1.5amp adapter in place of 10v/1.2amp adapter? – Quora. No it’s not safe for the most of cases. Since newer adapter has more terminal voltage therefore device is liable to draw more current and bad thing is that newer adapter is ready to provide more current.

Can you use a 12V 2A charger on a 12V 1A device?

The current draw (Amperes) is controlled by the device you plug in. So if you plug a 1A device into a 2A charger, it will still only draw 1A. If you plug a 2A device into a 1A charger, you will only get 1A. The device will charge more slowly (1/2 speed roughly) but everything will be fine.

What is the meaning of 12V 1A?

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.

Can I use 5V 2A for 5V 1A?

The adapter works perfectly if the rated value is stated on it. If you use 5V 2A for the use of 5V 1A, it will work. There will be a dip in the output voltage if you operate a load of 2.5 A rated value.

Is 1A or 2A better?

Literally, the output current of the 2A charger is larger than 1A (A is the abbreviation of current unit ampere), and the higher the current, the faster the charging speed. As for the 2A charger, it will not hurt the battery of the mobile phone more than 1A.

Can a 12V power adapter be used on a 1.5A device?

The device 12 V 1.5 A, means that it wants a fixed 12 V and at most will use 1.5 Amps current flow when running with 12 V. Since 1.5 is less than 3 and 12 = 12 then you should be OK. Adapter because your load device has a resistance rating that draws 1.5 amps.

Can you use an AC charger with a 5V Charger?

As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps. Can I use a 5V 2A charger with a 5V 1A device? Yes. Because a) the voltage matches, and b) the amperage provided is greater than that needed, you can use a 5v-2A charger with a 5V-1A device.

Do you have to match the voltage of the Charger?

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. In practical terms, that means the amperage rating of a power supply or charger must match or exceed that required by the device it is connected to.

Can a USB charger be plugged into the same voltage?

USB power supplies, for example, are the same no matter what. Input voltage — aka “mains” or line-voltage — is, of course, critical. Plug a device expecting 110 volts into a 220 volt socket, and you’ll probably see sparks followed by darkness as the circuit breaker trips. You’re also likely to damage the device.
