Can I use a 12v 2a adapter to a 12v 1a router?
You can safely use an adapter with the same output voltage, and a current (A/mA) rating equal or higher than the original. If you use one with significantly more voltage (and 12v is a full third more than 9v) then you might burn out your device.
Is it OK to use a lower amp power supply?
We recommend higher amperage to ensure cooler power supply and optimal charge time. 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.
How do you convert 12V to 5V?
We have 3 ways to do.
- Connecting 7805 in parallel.
- 12V battery to 5V 1.5A DC converter.
- Higher current transistor for 7805 Regulator.
- 2A transistor Regulator.
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.
What does 5V 2A mean?
DC 5V/2A, means that the input voltage, to recharge the battery is 5 volts of direct current. 2A is the amount of amperage that is suggested to recharge the battery.
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 a 12 volt power supply be used?
Most likely, yes. If your device requires 12 volt and draws 1 Amp of current, a 12 volt power supply will give the required voltage and will be able to supply the 1 amp of current it needs to run. A power supply that supplies a little more voltage might also work but depending on the device may cause the device to fail sooner.
Can a 6 volt power supply draw 300 Ma?
Yes. Power supplies are rated for the amount of current they can supply at a given voltage. If your device is rated for 300 mA at 6 volts, it will only draw 300 mA from the 1 amp of supply current available. Technically you could power three of these devices from the same 1 amp power supply: .3A + .3A + .3A =. 9 A or close enough to 1 amp.
Can a 2 amp power supply be used with a 5 Amp Supply?
Yes – the amperage rating on a power supply denotes the maximum output current that it can supply at the rated voltage. Drawing less than the rated amount of current (i.e. a 2 amp device with a 5 amp supply) will not damage the supply or the device being powered.
