Excellent and comfortable for a heated vest, it offers good battery life without being too heavy. You need to use good batteries, of course.

A box from a twenty-watt charger, but inside there's a regular one-two-ampere power bank without fast charging.

everything works, but when I received the pre-order, the case was in a bag, the protective glass, the screwdriver and screws were also in the bag and in the case, but here they just poured it into a bubble wrap bag and that's it, and the glass has no protective film. It feels like it's already used.
