xCompact warmth for small aquariums
The AquaMiracle Adjustable 10W Betta Heater is a thumb-sized submersible warmer designed for nano and betta tanks. At 1.97 inches long, it hides neatly behind décor while delivering steady warmth for up to a 1 gallon setup. It runs on USB power via a 5V/2A supply, compatible with standard adapters or power banks (not included).
Smart temperature control
Inside is intelligent inverter technology and built-in components that keep the water temperature stable within 1 degree Fahrenheit. The unit shows both the current water temperature and the set temperature, so you can tune the environment with ease.
Safe and reliable operation
Overheating protection stops heating when the water reaches 97 F, helping to prevent overheating. A memory function stores the last setting, so the heater resumes your preferred temperature after a power interruption.
Versatile and compact design
Beyond fish tanks, this heater can support small turtle enclosures, fountains, and certain plant seedling setups. Its tiny footprint keeps the display clean and uncluttered, even in crowded nano tanks.
