Charger 110v got plugged in 220v smoke

Yuko, Really the board and power supply are probably burnt out,
you did not state make and model#, probably not worth fixing.
RE POST with more info if you want.

check electrolytic capacitors in power board printed circuit board see if voltage was over their voltage rating. Damage hard to say did the same thing to a printer got white smoke from capacitors . check if unit has a orderable 220v power board circuit board you could order. May you have blown up power circuit board hopefully and nothing else.

The power adaptor has normally two voltages.
One is primary (Input) which is 110V AC in USA. 220V in UK and others.There are now a days Adaptors which accept both 220V and 110V. However the Adaptor pin will differ. It will be Flat pins for 110V and Round pins for 220V.

The other voltage is the Output which is fed to the Equipment and is Equipment specific. It can be 18V to 5.2 Volt DC. It varies equipment to equipment.. If a wrong Adaptor with output Voltage not matching with equipment requirement is selected, it may damage the equipment. Be careful.

Can't say for certain, but there are specific 110V and 220V versions of DCB101.
None are labelled 90-220VAC as would be normal for universal voltage equipment.
If you operate 110V equipment on 220V then you will most likely damage it with overvoltage.
If you operate 220V equipment on 110V then you will most likely damage it in over current or have it simply not work.

It is possible that the charger is universal, just not labelled as such.

Have a look on ebay for cheap converters:

if you need 110V US to 220V UK (6.99):

or 220V UK to 110V US (3.00)

Hope helps

No you cannot as 220v will damage the 110v the Logitech. You need a stepdown transformer to reduce the voltage from 220v to 110v. and then you can safely plug the Logitech into this stepdown transformer.

The power supply isn't a transformer, its a switching power supply. The power supply is different for different locations, but you should not plug a 110V only power supply into a 220v source or vice-versa. You should contact iRobot if you wish to obtain the correct power supply for another location or to determine if they have an autosensing model that can sense and adapt to either 110v or 220v. You can also use a step down transformer to convert from 220v to 110v. The charger should be using 20W or less, but it will be pulling the current in narrow surges from the peaks of the voltage wave (aka a high 3rd harmomic current) and you will need to use a 40W or larger transformer to avoid unexpectedly overheating the transformer core.

hi all,
I added another HowTo page for moding the DC18RA from 110V to 220V , you can find it here
Have fun and good luck

The problem is not with the batteris, but with your charger, you have to make sure it can take 220V or you will burn it. Look for a switch on it to change from 110V to 220V.

Hi there the solution for how to mod a DC18RA charger can be found here. The "how to" comes with pictures and descriptions and it should be easy to follow, and best of all it works :)
