Great for nano tanks / betta tanks. The innovative super mini size perfectly solves the headache of the fish keepers on the traditional heaters! Takes up less space, easy to hide, but in full power! Temperature range is 64-93F, for 2-4 Gallon tanks. - ACCURATE TEMPERATURE – Thanks to the intelligent inverter technology, with the in-built chips this thermostat keeps the heater at a constant temperature at an accuracy of 1F, much more accurate than the traditional knob-controlled heaters. The thermostat shows 2 readings – the current temperature and the set temperature – very easy to operate. - DRY RUN / OVERHEATING PROTECTION – Full consideration of safety. With the multiple protections this fish tank heater will stop working when the water level is lower than the minimum water level or when the water temperature exceeds 97F. You are free from “cooking fish”! - MEMORY FUNCTION – The last setting is stored in the thermostat. In case of a power cut, when the power recovers the heater will follow the last setting. - MULTIPLE USES – This heater can be used for both fresh and marine water. It can be not only used as an aquarium heater, but can also work for turtles, pet fountains, and plant seedling. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B4ZW4CKM | | ASIN | B0B4ZW4CKM | | Best Sellers Rank | #14,381 in Pet Supplies ( See Top 100 in Pet Supplies ) #19 in Aquarium Heaters | | Brand Name | AquaMiracle | | Color | Black | | Customer Reviews | 4.2 4.2 out of 5 stars (1,392) | | Date First Available | August 12, 2022 | | Date First Available | August 12, 2022 | | Directions | Adults 18 years and older. | | Included Components | Aquarium heater | | Item Dimensions LxWxH | 0.9 x 0.9 x 2.36 inches | | Item Package Dimensions L x W x H | 5.94 x 3.23 x 2.05 inches | | Item Weight | 70 g | | Item model number | SC06A020 | | Item model number | SC06A020 | | Manufacturer | AquaMiracle | | Manufacturer | AquaMiracle | | Model Name | SC06A020 | | Product Dimensions | 0.9 x 0.9 x 2.36 inches; 2.47 ounces | | Size | ≤ 4 Gal Tanks | | Specific Uses for Product | Small aquarium | | Target Audience Keyword | Fish | | Warranty Description | 1 Year Warranty | ## Images ![AquaMiracle 20W Super Mini Aquarium Heater for 2-4 Gallon Small Tanks - Image 1](https://m.media-amazon.com/images/I/71d5r6CezXL.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/461489991-aquamiracle-20w-super-mini-aquarium-heater-for-2-4-gallon](https://www.desertcart.tn/products/461489991-aquamiracle-20w-super-mini-aquarium-heater-for-2-4-gallon) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-20*
