110v and 220v devices ?

[Mark65428]

Can a device that come with 110v adapter work with another same voltage and amperage but on 220v current ?

I don't understand the question, which devices are you talking about ?

Any in general

If it comes with an AC-DC adapter then yes as long as you supply it the DC it wants you can replace the adapter. Watch the polarity, barrel plugs can be used either way by different devices.

They will come with 110v adapter yes

Check the label on the AC adapter. The vast majority are universal "switching" power supplies; they'll take anywhere from 100 to 250 volts AC at 50 or 60 hz, so they'll work anywhere in the world as long as the plug fits. It's only the very old, heavy, unregulated transformer kind you need to be careful with.

 

None of that matters to the DC side. If a device takes 12 volts DC at 1 amp, it doesn't care if that 12 volts comes from a 110 volt adapter, a 240 volt adapter, or a 12 volt battery.

Anything you plug into the wall should have written on it what voltages it supports. Anything that comes with a power supply that isn't a complete piece of garbage should support full range, 100-250V, but there's lots of garbage out there.

220v is voltage , current is something else.

 

Power  is Voltage x Current.

 

If the device has a built in power supply with wide input voltage capability (for example 85v - 240v AC), then it will work in either 110v or 220v countries.

 

If the device has a low voltage input (a barrel jack connector), and the power adapter it comes with outputs a low DC voltage (ex 5v or 7.5v or 12v or 20v or some other low voltage), then the device won't care about the mains voltage and what adapter is used ... as long as it gets the voltage and at least the amount of current it will be happy.

 

For example, if a monitor has a barrel jack connector and says on it 12v  2.5A (30 watts)  that means the monitor must be powered by a power supply that supplies 12v and AT LEAST  2.5A, so it could work with any 30w power adapter (12v 2.5A) or something higher, like for example a 65w laptop adapter (12v 5.4A) - the monitor will take as much as it needs.

 

Note there's two very common standards for barrel jacks :  2.1 mm Inner Diameter (ID) and 5.5 mm Outer Diameter (OD)   and 2nd is  2.5mm ID / 5.5mm OD (more common on higher current adapters, like 3A or higher for example)

This depends on device.

If we're talking about something like a fan or a hairdryer, they are strict about voltage and frequency.

 

If we're talking about USB chargers and laptop chargers, they typically will accept the whole range of 110V-220V 50Hz-60Hz.

 

It's your responsibility to check the specifications of your devices and power bricks before you ruin your equipment.

 

V = voltage

A = amp = current

Asking about "220V current" does not make sense.

 

You can share an AC Adapter between devices as long as the Voltages are the same.

For example, AC Adapter A powers Device A at 19.5V/3A.

Device B accepts 19.5V/1A. You may use AC Adapter A.

Device C accepts 12V/3A. You may NOT use AC Adapter A.

Yes those are cool but online product they dont say the adapter type. I bought free handset AT&T and they were 110v only

This sentence makes no sense. Another same voltage as 110 but on 220v? 110 is not the same as 220v.

If it is 110v only, then that is your answer. BUT I think you are confused. Can you take a picture of the brick and show us.

You purchased a free item?

The headset plugs directly into the wall?

 

I have so many questions.

Perhaps what needs clarified here is that the device draws current, it is not pushed. 

 

Voltage is "constant", so if your outlet or adapter says 12 volts, it always puts out 12 volts. 

 

Current however isn't constant. Your adapter can be rated 100 amps. However that's how much it CAN put out. If the device plugged into it only needs 1 amp, it will only draw 1 amp.
