## Description

TERRIFI Adjustable 10W Betta Heater - Small Submersible Fish Tank Heater with Digital Display Thermostat, USB Powered, for Aquariums up to 1 Gallon

## Features

- 🐟 Super Mini Size: This aquarium heater is incredibly small, measuring only 1.97" (5cm) in length. Perfect for nano tanks and betta tanks. Its innovative size solves the issue of space in traditional heaters. It's compact, easy to hide, and powerful! It's designed for tanks up to 1 gallon and maintains a temperature range of 64-93°F.
- 🔌 5V/2A USB Power Supply: This heater is powered by a safe 5V/2A USB source, eliminating the risk of electric shock to your beloved fish. Simply use a 5V/2A power adapter or power bank (not included) to supply power to the heater.
- 🌡 Accurate Temperature: Thanks to intelligent inverter technology and built-in chips, this thermostat maintains a constant temperature with an accuracy of 1°F, much more precise than traditional knob-controlled heaters. The thermostat displays both the current temperature and the set temperature for easy operation.
- 🛡 Overheating Protection: Safety is a top priority. This fish tank heater automatically stops working when the water temperature exceeds 97°F, preventing your fish from "cooking." It also has a memory function, so in case of a power cut, it will resume at the last setting.
- 🐢 Multiple Uses: Suitable for both fresh and marine water, this versatile heater can be used in aquariums, for turtles, pet fountains, and plant seedlings. It's a compact solution for various heating needs.
