Hello,

It is safe to use as long as the polarity is the same as the speaker power input. You will see a little diagram that looks much like - --0)---+ this means the tip is negative polarity and this --(0---+ means the tip is positive. These speakers need an adapter with a positive center tip on the jack. It also needs a min of 100mA which your power adapter does (1A) so that should be ok.

If the jack plug is not positive to the tip and does not fit in the speaker power jack socket you can go to your local electronic store and pick up a universal ac/dc adapter with multi plug sizes and get one with min 1A (100mA) or higher.

Regards,

Chris

Check Amperage of your Polaroidd and the power adapter. Same voltage but higher amperage might fry your Polaroid.
If won't work, you might buy one for Amazon

Cannot start up tabet and ac charger transformer is cold when plugged in


You will need an adaptor of at least the same output in both voltage and power. The only level that MUST be the same is the voltage. The power level must be the same or higher.

Where can i buy a ming an ac/ac adaptor model: MAO 123000, 120 v for garden fountain?


Similar issue with my fountain (Visage 3 tiered with lights). Contacted BOND MFG (csr1@bondmfg.com or www.bondmfg.com). They will probably send you a replacement if it is still under the one year warranty. Mine was not and they say it would be $20 for the adapter and $10.50 for shipping. Hope this helps.

Converting 120v AC adapter to 220v AC adapter


I live in the Philippines, but I've got relatives in the US who send me gadgets as gifts. I've had the same problem with my laptop before but when I called HP call center, they said that as long as it says there input 100 - 240V, then it's ok to plug it in a 110 or 220 socket. Here in the PH, we have 220V sockets, but Americans use 110.

Anyway, your phone says it can only be plugged to a 120V socket (max) so that means, you have to use a transformer (that's what we call it here. a black box-like thing) to convert the volts from 220 to 110. If you plug your phone directly, it might explode.

I hope i answered your problem.
