Are these power banks allowed in emergency go-bags?

Yes. All listed models are under 100Wh and suitable for bug-out bags and emergency kits.

Which power bank is best for long-term storage?

Anker and INIU models have excellent build quality and retain charge better during long-term storage.

Do outdoor-specific power banks like NESTOUT make a difference?

Yes. They often feature better durability, wider temperature tolerance, and rugged design for harsh environments.
