Compact glass aquarium heater designed for small tanks, turtle bowls and desktop aquariums. Provides reliable, safe heating with automatic temperature control and protections to keep aquatic pets healthy. Key benefits Stable water temperature: Precise temperature regulation maintains a consistent range, reducing stress for freshwater and marine animals and supporting stable biological conditions. Safe, low-voltage operation: Runs from a 5 V low-voltage power supply to minimize electrical risk in wet environments. Damage prevention and longer service life: Built-in dry-run protection prevents the heating element from burning out if the heater operates without sufficient water, extending the heater’s lifespan. Durable construction: Wear-resistant aluminum alloy housing protects internal components and improves overall durability in small, everyday aquarium setups. Easy to use in confined spaces: Compact glass design fits small tanks, turtle enclosures and desktop aquaria without taking up much space. Features and function Glass heating element: Efficient heat transfer for quick, even warming in small volumes of water. Automatic temperature control: Maintains target temperature automatically for consistent conditions; reduces need for manual adjustments. Dry-run protection mechanism: Detects unsafe operating conditions and prevents damage to the heating element. Low-voltage power supply: Operates on a 5 V input for safer installation and handling near water. Robust housing: Aluminum alloy outer shell resists wear and shields internal parts from impacts or corrosion. Compatibility and recommended use Designed for small aquariums, turtle tanks and desktop aquaria where space is limited and stable temperatures are essential. Suitable for both freshwater and marine (saltwater) setups when used according to tank size and species requirements. Ideal where safety is a priority: low-voltage power and dry-run protection reduce risks in home or office environments. Practical use scenarios Desktop planted nano tank: Keeps a 5–30 L (small) planted aquarium at a steady temperature for tropical microfauna and shrimp without dominating the tank space. Turtle or amphibian bowl: Provides gentle, controlled warmth in shallow turtle or amphibian enclosures where compact heating is needed. Office or dorm aquarium: Low-voltage, compact heater that fits small glass tanks and maintains stable conditions for small schooling fish or single-specimen displays. What to expect Compact, easy-to-place glass heater that automatically regulates temperature. Enhanced safety features to protect the heating element and reduce electrical risk. Durable aluminum alloy housing for everyday wear resistance and long-term performance. Note: Use according to tank size and animal temperature requirements. Follow installation and safety instructions for low-voltage connections and immersion limits.
