Can I use a 5V 2A charger with a 5V 1A device?
Originally Answered: What happens when use a 5V 2A rated power adapter for a device rated 5v 1a? It will work as normal. The 2A rating means that the power adapter is capable of supplying anything from 0 up to 2 Amps to the device.
What happens when use a 5V 2A rated power adapter for a device rated 5V 1A?
A device will only draw the current it needs. Under the same voltage, if your device is rated at 2A, it will only take around 2A from a 3A output of the USB power supply, leaving a 1A of headroom.
Can I use an AC adapter for DC?
AC or DC – Most adapters convert AC to DC, but it is still important to check the output.
What’s the difference between an AC adapter and a DC adapter?
A DC adaptor differs from an AC adaptor in that the DC adaptor converts AC electricity into DC electricity. For example, a 12 V DC adaptor sold in the United States will convert 120 V AC at 60 Hz into 12 V DC. Like its AC counterpart, a DC adaptor is also rated for maximum power output in watts.
Can I use a 12V power supply on a 5V device?
The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc.
How do you convert 12V to 5V?
12v to 5v converter using a voltage divider: You can run two LEDs in series across the resistor R2 while taking input from 12V lead-acid battery or a 12v adaptor as an input. Components required: One 12v battery, 1.8k resistor, 1.3k resistor, connecting wires. This circuit is a voltage divider schematic.
Can I use a 5V adapter to power a 9v device?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn. It could be however, that your adapter has an internal resistance causing the voltage to drop to ~5V, so it could work in this case, if the adapter can supply the needed current…
Can I use a 4.5 V adapter to power a 5V device?
They’re very stable on the output voltage and can kick out an amp or so. It’ll work fine.
Can I use 5.5 V instead 5V?
I’ve run 5V devices at ~5.7V without problem (their specs say 6.5V max). The main points from other threads were: – when you run at a higher voltage, your margin of error is smaller. For example, if you run at 5.5V then you won’t be able to tolerate a, say, +1V spike as easily as you would when running at 5V.
Can I use a 5V adapter to power a 6V device?
The short answer is No. A 5V, 2A adapter gives 10W of power and the 6V,1A gives only 6W. That is only scraping the surface. Transistors are present in almost every electronic device today.
Can I use a 5V adapter to power a 3V device?
There is not such thing (or there should be no such thing) as a 3V USB anything… USB is 5V, and always will be. It is a standard that all devices must comply with. This means that you should not be able to find an AC adaptor to 3V with USB, If you do find it, don’t buy it.
How do I convert 5V to 3V?
The simplest possible step-down circuit is a resistive divider. Drive your 5V output into a chain of resistors, from which you tap your 3.3V logic input. A chain consisting of a 2.2k and a 3.3k resistor should produce a 3V output from an applied 5V input.
Can I use a 10v adapter for 12V?
No it’s not safe for the most of cases. There are two reasons. 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.
Is it OK to use a power supply with higher amps?
The amperage rating on your power supply simply means that the supply can put out up to 2 amps, so as long as the voltage matches (12 volts) you could safely use a higher amp power supply for your device.
What happens if I use a lower amp charger?
Amperage is the power pulled by your device while being charged and used. If you get a charger with amperage less than your original power supply, you risk overheating your charger, burning it and in many case your device will stop functioning and/or charging.
