An essential item in an emergency kit; a large capacity power bank

At the weekend, a friend in Ireland had shared an Instagram reel of her power bank of choice. I was impressed by three things of the power bank in question. One, that it has an inbuilt torch, which you can use to find your actual torches in case of  power outages at night. Two, that there are three ports for cables on the unit. Three, that there is a digital screen which shows how much power is left in the power bank. 

It got me thinking that my power bank is not up to scratch and I was considering upgrading. Then, a large earthquake happened off the coast of Aomori Prefecture last night, December 8th 2025, and the need for a new power bank feels essential right now. I do have a power bank in my emergency kit, but it is not large enough and it is missing the features outlined in the first paragraph.

At my last visit to the Saitama Prefecture Disaster Prevention Learning Center I noticed that in their samples of emergency kit contents they had an "Asknut" power bank. Asknut seem to be a brand recognized for their large capacity, providing features like LED lights and multiple outputs for charging devices. Some of them come with solar chargers too. It would also seem that it is a brand that is widely available in Japan. I personally have no experience with this brand though.

Have you heard of / used Asknut Power Banks? And / or what large capacity power bank would you recommend?
