I ended up getting non powered gloves from Macpac
First these, which I thought I'd use as a base layer.

Then these which I would put over the above. They are thick, padded, and lined with a fleece-like material. Warm on their own!

Weirdly the review on the above gloves also did what I did (merino inner layer, piste glove outer layer) and said it didn't work. That reviewer was cycling, so I can't vouch for that. But at a campsite in 0 degree weather camping in the Blue Mountains and also with some strong gusts? This combo worked AWESOME. My hands not only were warm, but they actually warmed quickly when I had to take the gloves off to use the computer and put them back on afterwards.
Not only that, but I was totally impressed by the merino gloves on their own as well. They're not thick gloves at all, yet really did a lot to take the chill out of my hands.
Very good purchase IMO
