Can you use a 12V adapter for a 10v device?

Can you use a 12V adapter for a 10v device?

5 Answers. Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed.

What happens if I use a 5V adapter on 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…

Are 12V AC adapters interchangeable?

As long as the voltage is the same on the adapter and on the device (also, I have 9V DC and 9V AC adapters, do not mix these up) and be sure the current required is less than the amount that the adapter can source otherwise you risk overloading the power supply.

Can you use a 19v adapter on a 15v device?

No! The adapter will charge the battery very slowly, however the power adapter voltage being 4 volts higher than the battery rated voltage will create a problem that will damage the battery.

Can I use 500mA instead of 300mA?

What happens if I use a 9V DC/500mA power adapter for a guitar pedal that requires 9V DC/300mA? – Quora. Assuming the polarities are the same (center negative most likely), it will work just fine. The pedal’s mA requirements are a minimum, and the power adapter needs to provide at least that much current.

Can I use 12V adapter for 7.5 V?

1 Answer. You should never use a significantly higher voltage rating adaptor on any kind of electrical device.

Can I use 12V ups for 9V router?

However, the 9 Volt router cannot be run on the 12 Volt UPS. The 9 Volt router is meant to be run on 9 Volts and attempting to power it with the 12 Volt UPS will result in an overvoltage thus permanently damaging the router.

Can I use a 12V power supply on a 9V router?

You cannot use that adapter because it is outputting more voltage than the original (12v vs. 9v). This has a likely chance of burning out one or more of the components within the router. The output voltages must be identical.

Can I use 9V adapter for 12v router?

Can I use a 9V adapter for 8v?

If the old supply put out 8 V and 2.6 A and the equipment says it wants 8 V, then the obvious answer is a power supply that puts out 8 V and 2.6 or more amps. The equipment might be OK with 9 V, or not.

Can I use 1000ma instead of 300mA?

Re: OK to use a 300ma adaptor with 1000ma Roland device? No. Maths in these matters is simple: to power a 1000 and a 300 mA device, you’ll need (at least) 1300 mA and probably some additional circuitry to prevent the smaller device from slowly frying.
