Review on KEDSUM Battery Aquarium Air Pump: Ultra-Quiet Rechargeable Fish Aerator with Dual Outlets - Ideal for Fish Tanks, Outdoor Fishing, Fish Transportation, and Power Outages by Shawn Hill

I was drawn to this model because it is rechargeable and it is quiet. Bonus is it comes with tubing and air stones. Tested its run and recharge time, and it held up to its description claims. Intend to use for keeping live sand shrimp fresh/alive longer, haven't been able to test it for this specific purpose yet but suspect it will do fine.April 23rd - Have used on two fishing trips so far and its worked great. Keeping the sand shrimp in oxygenated salt water (about 1 1/2-2 gal bucket) much more lively than without * I covered with a mesh bag to diminish the output because shrimp swimming continuously will just die, they need a calm area in the container. The intermittent mode was sufficient for my 3 day trip. Hopefully it lasts a long time.
