SUPER MINI SIZE – “The thumb size heater”. By far the SMALLEST 10 Watt aquarium heater. Super short – measures only 1.97 inches (5cm). The innovative super short length perfectly solves the headache of the fish keepers on the large size of the traditional heaters! Takes up tiny space, easy to hide, no more eyesore!
TEMPERATURE PRESET 78℉(26℃) – The best temperature for tropical fish is 78℉(26℃). This betta heater is preset to that temperature, which makes fish keeping much easier – fix the heater in the aquarium with the suction cup, plug in, and you are good to go! The intelligent in-built chip will keep your water temperature at 78℉(26℃) automatically. Kind Reminder – Use for water capacity less than 1 Gallon only.
USB POWERED – This fish heater is USB powered. The 5V/2A low voltage is very safe to both human and fish. Note that 1 – power adapter is not included; 2 – Output of the power adapter should be 5V/2A.
OVERHEATING PROTECTION – Although tiny in size, the intelligent chip of this heater is still designed with overheating protection. When the water temperature exceeds 97℉, the protection will be activated to cut off power supply of the heater automatically. You are free from “cooking fish”!
MULTIPLE USES – This fish tank heater can be used for both fresh and marine water. It can be not only used as a nano aquarium heater, but can also work as a turtle heater, pet fountain heater, and plant seedling heater (make sure the water capacity is below 1 Gallon and ambient temp. is higher than 61℉/16℃).
