  • SUPER MINI SIZE – This mini fish tank heater is just about the size of a thumb – only 1.97”(5cm) long. It's fantastic for nano tanks/betta tanks. The groundbreaking super tiny design brilliantly addresses the fish keepers' annoyance with traditional heaters! Occupies less space, easy to tuck away, but packs a punch in power! Temperature ranges between 64-93F, suitable for tanks up to 1 gallon.
  • PRECISE TEMPERATURE – Courtesy of sophisticated inverter technology, with its in-built chips, this thermostat maintains the heater at a steady temperature with an accuracy within 1F, a lot more precise than conventional knob-controlled heaters. The thermostat displays 2 readings – the current temperature and the designated temperature – making it super user-friendly.
  • 5V/2A USB POWER SOURCE – This ultra-safe 5V/2A USB power source keeps you worry-free from any potential electric shock risk to your cherished fish! Use a 5V/2A power adapter or a 5V/2A power bank to fuel up the heater. (Note: Power adapter or power bank not included)
  • OVERHEATING SAFEGUARD – Safety comes first. This betta heater will automatically stop running once the water temperature exceeds 97F. No more fretting about "cooking fish"!
  • MEMORY FEATURE – The last setting is saved within the thermostat. In the event of a power outage, the heater will revert to the last setting once power is restored.
  • VERSATILE USES – This betta fish heater can be used in both fresh and saltwater. Not only can it serve as an aquarium heater, but it also works well for turtles, pet fountains, and plant seedlings.


Improve your aquarium setup with our Super Mini Aquarium Heater. Designed with top-notch technology for better temperature control and safer operation, it's the ideal accessory for any small tank/nano tank/betta tank owner. Your fish will love the stable, warm environment that our nano fish tank heater creates. Give your aquatic pets the comfort they deserve with the small aquarium heater.

Small but mighty. It heats my 2.2 gallon tank perfectly. Definitely worth the money.

Worked really quickly in our 2 gallon tank and my beta is definitely more active now and seems happier. And somehow the water stays cleaner longer not sure why that would be. Maybe the beta is eating more of its food keeping less sludge in the tank. I’m very pleased with this mini heater.

Piece of garbage DO NOT BUY it doesn’t keep heat and system to set heat is janky. Couldn’t even keep a 2.5 gallon slightly warm
