I for one think it’s an excellent idea. I had a similar idea some time back. I think a longer 10k version would be best.
You should have posted your idea to the wish list for future products topic. I’m sure @ndalby will move your post soon.
Also cc @AnkerTechnical if enough people request a flashlight/power bank they will make one.
What products are on your wishlist for Anker to make next?
