Hi folks

I'd really appreciate some help with finding a suitable power adaptor for some home weather stations that I'm looking to import from the UK to sell in New Zealand (I've been through all the legal compliance for the stations with RSM). The station's display screens come with a UK plug power adaptor which reads:

Input 100-240v - 50/60Hz 0.25 Max.
Output: 5.9v - 0.5A 2.95W, then the 'centre positive' symbol.

The display screen has a barrel power connector plug (3mm outer x 1.1mm inner), with 'DC6v' written near it.

I can't find anything available in NZ that meets all these specs. But I'm wondering whether it would need to. The screen can also be powered by 3 x AA batteries, so that's only 4.5v. Perhaps a USB wall charger + a barrel connector to USB cable might work?

Thanks for any advice you might be able to give.

Thanks very much. I see the plug in your link is rated it 2.5A output. The one it will be replacing is only rated at 0.5A. Is that not an issue?

That is a Maximum, devices will draw what they need and the power supply will supply that.

The issue will be cost, a 2.5A adapter will be more expensive. I assume you've done your research and checked that this weatherstation isn’t already available with an Australian approved adapter.

If you are looking for quantity of adapters then go to element 14 instead of jaycar.

No great amount of stock and assume you need to buy blade (head) separately.

I find jaycar on the expensive side though super handy if you need it in a hurry

Bought some other adapters from here for usually cheaper than jaycar

Comes with a bunch of adapters which might have the one your after

This is a multi polarity and plug size adapter which is great when you dont know what you need but there's a risk the customers will reconnect it with the wrong polarity.

When they do that they may let the smoke out or the system may simply not work but either way, they'll be needing support. OP would be setting up to fail with that adapter.

Thanks, their price is less than half of what PBtech charge for the same product.
Unfortunately, due to the recessed location of the plug socket on the back of the weather station, this particular one is too fat at the point where the barrel connector part connects to the cable.

I completely agree. If I go down this route, I'll need to connect the right size barrel connector with the correct polarity myself, before sending to the customer!
A hassle, but I'd be willing to do it, at least in the short-term.

If it's a one-off you can glue the fitting to the end of the cable to prevent Mr Co**up coming to visit. Not sustainable for a volume operation.

Got any info for the weather station you'll be importing?
