Anker always makes good stuff. And I have several of the INIU power banks too. I'll give you one more somewhat unconventional choice. This chunk of power has 100 watt hours of capacity. It has one built-in in/out USB-C corded outlet (100w), one more in/out USB-C port (45W) and one USB-A port. This should keep everybody's phones going. You will not need to worry about running out of power. Uses LiFeP04 chemistry. The only real drawback is that it does not have a handle. $51. I have a couple of these. https://www.amazon.com/AFERIY-Portable-Retractable-Generator-Protections/dp/B0F13V4X6B/ref=sr_1_3_pp
I also would recommend a power bank instead of a flashlight (heresy I know). I have a couple of these little guys. Capacity is 100 watt hours which will keep everything charged up easily. It charges up via a USB-C cord. It has two USB-C output ports and one USB-A outlet port. https://www.amazon.com/AFERIY-Portable-Retractable-Generator-Protections/dp/B0F13V4X6B/ref=sr_1_3_pp
