Can I use 12V 1A for 9v 1A?
NO! Your output voltage is wrong, which is the important part. You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original.
What does 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.
Can I use 12V 1.5 A for 1A?
No, a 1A power supply isn’t a replacement for a 1.5A power supply.
Can you charge 1A with 2A?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed.
Can I use 12V 3A for 12V 1A device?
A device only draws as much current as it needs. No more, no less. The rating on the supply is simply saying that it can deliver up to 3 amps as needed, meaning a circuit designed for a 1 amp supply will run on it without a problem. You could hook up a 12V 50A supply and the device will still draw less than 1 amp.
Can I use 12V 1a for 9V 0.6 a?
No you can’t.
Can I run a 9V device on 12V?
If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.
Can I use 2A charger for 1A?
If the 2a charger has the same output as the 1a there shouldn’t be any problem. You should check with the store you purchased your device from.
Can I use 2.4 a to charge 1A device?
Most USB charging stations provide 1A or 2.1A of power per USB port. 1A ports are fine for mobile phones, but aren’t suitable for tablets. To ensure you can charge a range of devices, it’s best to go with 2A ports at minimum. High-power USB ports—2.4A to 5A—are available.
Can I use a 12V 3A power adapter on 12V 1.5 a device?
Yes, you can use a 12V 3A power adapter on 12V 1.5A device. You can also use a 12V 0.5A power adapter but the charging time will be three times longer.
Is it OK to use 9V adapter for 12V?
What is this? When a pedal says “9 – 18V”, it means it can accept voltages anywhere within that range. That means you can use a 9V power supply, a 12V supply, or an 18V supply without any problems.
Can I charge 5V 1A with 5V 2A charger?
Using the 5V 1A charger to operate a device that is normally charged with a 5V 2A charger is a bad idea. The smaller rated 1A charger is likely to overheat when used in this manner. In the worst case it could even catch fire so don’t do this.
Can I use 2a charger for 1a?
Can I use 12V 3A for 12V 2a?
Yes, you can use. The voltage rating of the device should not decrease but for current it will work as it means the device need 1.5A current to work and our adapter is capable of providing till 3A current. Yes it will work fine.
Can I charge 1A with 2A?
The chargers that come with Android tablets are designed for greater amperage than similar devices for Android smartphones. For example, the charger for a tablet is designed for 2A, while the charger for a smartphone is only for 1A.
