5v should be close enough . 5v would be easier to get .

Its probably a charger not just an AC adapter, all the stupid voltage ones seem to be like that. I have a couple of things that need a 12.6v one and they are also current limited to look after the battery charging.

just to make sure,

 

5v, and as long as the outlet plug fit and can deliver more or equal to 800mA it should be fine?

Or put a dropping resistor across it if it's really that finicky. However as @richms pointed out, something with a voltage that weird may be a charger rather than a generic power supply. What's the connector look like?

Methinks it is for a breast pump - Googled the "67050 pump" bit.

 

Something like this I guess.....

 

https://www.amazon.com/Adapter-Medela-Electric-Breastpump-Supply/dp/B075D8B35J

 

Looks mighty like an old Nokia charger. I will have a look myself.

 

EDIT: Actually, that Amazon link takes you to one that handles 100-240V AC 50-60Hz so that could be an option.

the plug looks like this, 5.5mm, it is for a Medela breast pump.

That looks like a 5.5 x 2.5, which alongside the 5.5 x 2.1 are kinda the universal standard so any power supply with a 2.1/2.5 mm barrel jack connector should do it. A 2.5 will typically also often work with a 2.1, although obviously not the other way round, and worst-case you can get 2.1 2.5 adapters from Jaycar for a few dollars.

 

 

Another option is to get a USB to barrel jack adapter so you can power it from a USB power supply.

 

 

As someone else pointed out though, since it's a switchmode power supply all you need is a NZ -> US plug adapter to run it here.

i actually didnt know there is a such thing as a USB to barrel cable. i could actually get the cable as use my iphone 5w charger for it and it might work, cos the charger is 5w 1A

That supply was an alternative from Amazon not the OP's original. The US is a big enough market for a 120v only model to be worthwhile and Americans tend to stay put.

Ah, yeah, reading comprehension fail, should have checked the original message. Weird that they make a switchmode supply that isn't universal-voltage.

thank you all for your help,

 

I brought a USB to barrel cable, and use it with the apple 5w adaptor.

 

it seems to be working on, the pump goes without any problem.

 

 

 

thanks alot
