They are not the cheapest and charge for shipping but they should be good quality and they have a unique feature that all others are missing. You can use them as a power bank directly with just a USB C cord, and it has a button and lights for battery capacity check, and they come with a cord and adapters. Make sure you have a light that can handle the extra length of a protected USB C button top, because many lights can not. Also make sure your light head won't press down on the battery power button.
