Adjustable 10/20/30W Small Aquarium Heater Submersible Fish Tank Heater Betta Heater Turtle Heater Super Mini Aquarium Heater with Digital Display Thermostat, for 1-6 Gallon Tanks

SUPER MINI SIZE – This small aquarium heater is 'thumb size' - only 2.36' (6cm) in length. Great for nano tanks / betta tanks. The innovative super mini size perfectly solves the headache of the fish keepers on the traditional heaters! Takes up less space, easy to hide, but in full power! Temperature range is 64-93F, for 1-2 Gallon tanks.

ACCURATE TEMPERATURE – Thanks to the intelligent inverter technology, with the in-built chips this thermostat keeps the heater at a constant temperature at an accuracy of 1F, much more accurate than the traditional knob-controlled heaters. The thermostat shows 2 readings – the current temperature and the set temperature – very easy to operate.

DRY RUN / OVERHEATING PROTECTION – Full consideration of safety. With the multiple protections this fish tank heater will stop working when the water level is lower than the minimum water level or when the water temperature exceeds 97F. You are free from 'cooking fish'!

MEMORY FUNCTION – The last setting is stored in the thermostat. In case of a power cut, when the power recovers the heater will follow the last setting.

MULTIPLE USES – This heater can be used for both fresh and marine water. It can be not only used as an aquarium heater, but can also work for turtles, pet fountains, and plant seedling.
