Review on 🐠 Rechargeable Aquarium Air Pump for 20-400 Gallon Tanks: High Output Oxygen Supplier for Fishing, Seafood Transportation, Hydroponic Systems by Sarah Nguyen

I returned but decided to cancel the return for ONLY one reason; I live in California and we have wildfires that cause security failures. I only keep it for emergencies. The biggest problem I have is that the battery does NOT last as long as advertised. Only up to 6 hours on a full charge of continuous use when 12 hours is quoted. I've never tried the 10 second on/off mode. But if the continuous full charge is only half of what is stated, then who knows other modes. Unfortunately, this is not the only problem. The pump is not powerful enough to support 2 lines. not worth your money. But it's definitely quiet.
