Looking at the charging preferences of the Steam Deck, which from my research wants 45W at 15v/3A, it looks like the larger model should work just fine. And with it being $15 USD / $18 CAD this could be an incredible bargain.
It’s so new though I can’t find any info on it being used with a Steam Deck. I’ll definitely be grabbing one to try, as it would be perfect for my USB hub that sits by the TV.
Let’s be honest, the reason for that policy is so that if a Chromebook does fail you can go back to the manufacturer for warranty coverage.
I would trust an Anker charger just as much as an OEM charger.
Obviously anker would probably be fine, I am talking about these no-name boxes from unpronounceable amazon sellers
