It pairs with common USB power sources—like phone chargers or portable banks—making it perfect for apartments, offices, travel tanks, or educational setups. The 26°C constant temperature helps reduce fish stress, supports consistent metabolism, and promotes healthier feeding and activity patterns. With a compact, submersible design and clear status indicators, it’s easy to monitor and adjust as your tank inhabitants grow or change, and the option to add a second heater provides flexible control for larger nano-tanks. For best results, ensure you use a reliable 5V 2A power supply and follow usage notes to maintain even heating across your small aquatic environment.\u003c\/p\u003e\n\u003ch1\u003eSPECIFICATIONS\u003c\/h1\u003e\n\u003cp\u003e\u003cspan\u003eBattery Included\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eNo\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBrand Name\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eNONE\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eChoice\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eyes\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eHigh-concerned chemical\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eNone\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOrigin\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003eMainland China\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eType\u003c\/span\u003e: \u003cspan style=\"color:#333\"\u003efish\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eUSB Mini Aquarium Heating Rod For small Fish Tank 26°C Constant Temperature Aquarium Heater submersible Thermostat Heater 10W\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Description:\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eNoteThe product will work with a red indicator light, and when the product reaches a temperature of 26 degrees Celsius, it will light up a green indicator light and pause the work.
