Power banks

[So]

Father Christmas brought a heated coat for my wife which runs off one of these.

She needs a spare one, which I said I would buy for her. I was a bit shocked to see the price though.

Is this going to be any different from an ordinary power bank costing half as much? I don’t want to electrocute my wife or set fire to her ideally.

So long as the connection from the coat to the powerbank is standard, I don't see why you couldn't buy any old powerbank.

I'd recommend Anker products. Cheap and reliable.

It may be a capacity issue.
Ones that charge a phone don't need huge volumes of juice but I would suspect that a heated coat would be pulling a fair bit more.
See if you can see the amperage and capacity on the one you have and match that.

We've got a couple of heated tops which run off 5V powerbanks.

You really need to look at what the garment manufacturer specifies in terms of power draw.
Mine need a power bank which can supply 2A at 5V continuously.

I ended up buying about 5 different power banks to try as I wanted something nice and slim but with a good capacity.
I found that one of the Anker ones was quoted as supplying 2A when in fact it didn't, so make sure you can send them back for a refund if they don't work.

Thanks chaps. It may be just as well to buy one of Blazewear's own. Yes they look pricey, but if anything goes wrong they can't argue.
