Hmmm... I'm not sure what you're seeing to be honest. The link should be to a slim 5000mah magsafe battery that attaches to the back of iPhones.

The Anker Nano Power Bank (5K, MagGo, Slim). No screen, charges via USBC.

Seems like this product, on the Anker Nordic page so that it works for us who for whatever reason are booted from the main Anker website: https://www.ankernordics.com/products/a1665-anker-nano-power...

Yeah, that would work. The first party Apple MagSafe power bank is also a decent alternative.
