fishkeeper Battery Powered Aquarium Air Pump, USB Rechargeable Aerator Fish Tank Air Pump for 5-125 Gallons Portable Oxygen Pump for Outdoor Fishing, Power Outages and Emergency (4W 80GPH)

Just get a few more 5 gallon buckets. The ones from Menard have better lids than the ones from Home Depot. I bought this battery operated pump, which can run two air stones (for 2 buckets), https://www.amazon.com/dp/B0D4987P84?ref=ppx_yo2ov_dt_b_fed_asin_title. You can also use it plugged in as a regular air pump.
