I have a japan to international travel adapter plug. I think the shape of the pins mean it can accept a few different types it fits japan appliances anyway which is what i need. The japan supply pins on the plug are bent for nz. The plug has 120v 10A written on it. Would it be ok for 240v? I assume it has been used for 240v before as it was not me that bent the pins. It is pretty simplistic in design. And yes the appliance has a wide voltage input.

So double the rated voltage then... I wouldn't. The appliance may well function, but if the insulation is not up to the job and you get a shock from it, all for the sake of a few dollars for a new correctly rated one.

Bent pins cause problems. The plug does not exactly fix the socket. This creates a hazard.

The act of bending the pins can cause unseen damage within the plug itself.

The physical bend can cause damage outlet sockets by exerting force in a direction they are not designed for.

True, I should probably just buy one. On a side note, how do the reset-able fuses in cheap 4-way adapters work?

Bending pins is not acceptable. The pins are also highly unlikely to be insulated (which is required under NZ/AU regs) so this makes it unacceptable and dangerous.

Adapter plugs should never be used long term for anything as it's dangerous.

How are they dangerous long term?

I have a couple of devices that came with those power supplies/ac adapters that have the plug built into a sealed unit. This makes it impossible to change the plug. The only choice is to use a plug adapter or to bend the pins. I have bent the pins. This did not crack the housing or damage anything else. Would it still be regarded as dangerous and if so, what then is the solution?

Nicer than a travel adapter is a multi socket board from the appropriate country, with a NZ plug fitted. That's what I use for UK appliances, still a few of those left after ten years living in NZ

It doesn't comply with AS/NZ electrical regulations

If it's an AC or DC plugpack then simply buying a new plugpack is the best option.
