Does this work with 220V or 110V only?

This is a small electric screwdriver that charges an interior 4 volt battery from ordinary 110V house current. It will not work with 220V. It will probably blow up spectacularly if you try that. It is clearly intended for 110V only.

It does work both ways from 110V to 220V and from 220V to 110V. (Not sure if there was a typo in your question as I'm not familiar with 100V. I know in US they use 110V and in the country I am 220V). You just have to put the switch to the right position). Hope it helps.

This does not convert 220v to 110v. You have to have a dual voltage feature on the item you want to use it for, and if not, a separate power converter.

It accepts the US 120V ... there is no facility for 220V. Works like a charm at 120V.

It works on a 5V adaptor, this adaptor can be 110 or 220V. It will work all over the world.

110V, you need a step down converter to use it with 220V. Don't get caught, I did.

It does work perfectly with 220 V. The only thing you will need is adapter for US plug.

It uses 110V & 60 Hz (which is standard for the USA). No for 220V, etc., however.

Mine is only designed for 115v. they may offer a 220 v but I didn't check that out since we have 115v here.

US only -- so 110v - I would check with the manufacturer before using this overseas.

I was under the impression that it is 110v only. Maybe an inverter attached to a car or car battery?

I have only used it with 110 volts but the manufacture claims it will charge between 100 to 240 volts.

110 volt only unless you buy the over seas version which has charger for 220 volts.

Unfortunately it's 110V only. However the units can also be charged by USB.

It operates only on 110V AC. You'd need a 220 DC converter to plug this into

Hi. This is a U.S. model and does not support 220 V and only supports 120 V.

The one I bought and used in Australia was 110V only, so I have used a 240v - 110V adapter.
