Note sure if this is the correct forum but I buy the occasional 4TB external HDD form AmazonUS and they only come with US plugs (weird I know). Would anyone know if its possible to buy the same power supply but for NZ somewhere ?

Otherwise would anyone know of a good (cheap) US to NZ adapter that isn't huge (I get from The Warehouse but they always have these stupid wings on them to specifically be as inconveniently big as possible).

What brand and what type of connector?

Well the HDD is a Seagate STEB 4000100 and the power supply is a standard HDD power supply - 100-240V 50/60Hz input 1V/1.5A output. Model ADS-25E-12 ShenZhen Honor Electronic Co., standard American two prong brick, if thats what you want to know.

That does indeed look like the one I'd like to get, but should I worry about the 1.5A/2A bit at the top of the page? It does say later down the page 1.5V output. Any danger of it blowing up the HDD as the supplied (american) unit mentions 1.5V only ?

The spec of the ADS-25E-12 is 12V 1.5A.

The spec of the WA-18H12 is also 12V 1.5A.

When replacing a adapter you want the same voltage with the same or more current output. The device will only draw as much current as it needs.

If you buy it from PB you should use the free shipping code: WHOLOVESPB

It's generally suggested that you use an adapter with the same or higher current rating but be aware that some of the cheaper adapters rely on a draw of that rated current to get the voltage right. You might find for example a 12V adapter rated for 3A gives 15 volt when supplying a device that's drawing less than an amp.

Thanks. I also assumed (underline assumed) the HDD will just take what it needs, no problem, but now you've put me off a bit with that 15V thing. Maybe I'll see if I can rearrange the power supplies in the board I'm using to find a bit more space and/or try to find a compact travel adapter so I don't have to worry about it.

rb99:

1V/1.5A output

I'm pretty sure you mean 12V/1.5A (both figures do matter).

But are you looking for a replacement power supply, or just a more compact US to NZ plug converter to use with the US power supply?

As jmp246 mentioned, they're both 1.5A

A replacement (1.5A) NZ power supply seems better as I obviously wouldn't need an adapter at all, but then adapters are cheaper and more versatile but seem to be too big (and the more compact ones all seem to be NZ to overseas ones, not the other way round).

So would be OK with either really, just depends on price/availability/size.

Adapters are US$0.50-1.00 on Aliexpress (free shipping). More stable 2/3 prong (grey), and tiny 2 prong (black) ones. I'd go the bigger ones as it's a nicer connection, but they don't fit in power boards that have the circular recess - shape just doesn't quite fit.
You know what you have is of OK quality. Don't see an adapter being that much of an issue... And like you said way cheaper.

And like others have said so long as plug and polarity is correct, with the same voltage, and the same or higher amperage. It'll work fine (if not garbage).

One person supports this post

Order a USA powerstrip for them all. Just dont get one with surge protection since 230v will make that kick in and clamp it and blow the breaker.

The locally sourced adapters are that size to prevent misinsertion of the plug leaving live pins hanging out, or someone putting the earth pin into a live hole etc. If safety isnt a concern get the aliexpress ones, but some have thiner pins to chinese standards which dont grip in cheap locally sourced powerstrips.

Be aware whenever replacing DC power supplies that there are also two very similar plugs with the same 5.5mm OD - 2.1mm and 2.5mm female to match the pin on the socket.

Thanks, am sure two different connectors that'll look (almost) the same seemed like a good idea to someone. Am beginning to think coming out of the caves was a mistake...

I thought the UK/US power pin adaptors wernt legal in NZ, or at least couldnt be sold here ?
Due to being wobbly & unsafe

The bangood/ali ones Ive had were really bad: super loose, wobbly , but worked as long as the thing plugged into it had almost no
weight

Also, make sure your US power packs are actually dual voltage , not just 110v .
