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 Donald Phi

While this is a compact, well built and functional product which helps keep fish alive longer in a tank, also with a great battery life, has two design defects which I cannot understand what they were thinking. First it is very easy to turn it on accidentally because the power button is located in a position where you would naturally grab the item and the slightest touch will hit this button, but worse and less understandable, when you unplug the charging cable it automatically turns on, why? If you don't realize it's on, you may well be depleting the battery while you travel to your fishery. This happened to me the first time because this device is very quiet while operating. I do hope the manufacturer can improve these flaws with the power button and the unexplainable auto turn on after the charging cable is unplugged.Edit: After reading some reviews I realized this item may designed manly for ornamental fish tanks. In my case I am a fisherman and use it for a different purpose. To me the auto-turn on feature is a problematic and the capacitive button is inconvenient in my opinion. I understand now that for people with fish tanks in areas where there's constant outages the auto-turn on feature may come in handy. Not for me, unfortunately. Every time time someone in my household "helps me" charge it they leave it on after they disconnect it.
