Mini USB Aquarium Heater with Temperature Controller for Small Fish Tank

Mini USB Aquarium Heater with External Temperature Control This compact 10W aquarium heater is designed for small fish tanks and turtle tanks with a capacity of 1 to 2 litres, or approximately 0.3 to 0.5 gallons. Powered through a USB connection, it offers a straightforward and efficient way to maintain a stable water temperature in smaller aquatic setups. External Temperature Control The heater features an externally controlled electronic temperature setting, allowing you to adjust the water temperature between 18°C and 34°C (64°F to 93°F) with ease. A built-in high-precision sensor monitors the water continuously, while the three-digit display shows the current temperature in real time. Temperature adjustments can be made in precise increments of 0.5°C or 1°F, giving you accurate control over the environment for your fish or turtle. Automatic Constant Temperature and Safety Features Once the desired temperature is set, the heater automatically activates when the water falls below the set level and switches off once the target is reached, keeping the water consistently warm. For added safety, the unit automatically shuts down if the water temperature exceeds 36°C (96°F). The heater must be fully submerged during use, and it is designed to switch off automatically when removed from the water, offering anti-dry protection to prevent overheating and improve overall safety. USB Power Compatibility This heater can be powered through a USB plug connected to a mobile phone charger or a portable power bank. Please note that the output voltage must be 5V 2A, and a DC 5V/2A fast-charging plug is recommended for reliable performance. This makes the heater a convenient option for use in smaller tanks where a standard mains-powered heater may be impractical.
