Powered by a standard 5V\/2A USB interface — safe enough to run from a phone adapter or power bank, with no high-voltage risk. The built-in thermostat locks at 26°C (79°F), the biological sweet spot for tropical fish, betta fish, and amphibians like Pacman frogs. Small enough to tuck behind decor without intruding on swimming space. Available in multiple versions including a basic constant-temperature model, an upgraded dry-run auto shut-off model, and an adjustable touchscreen model for tanks requiring a different target temperature.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eUSB 5V\/2A powered — no high-voltage risk, runs from any adapter or power bank\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eLocks at 26°C \/ 79°F — biological sweet spot for tropical species\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eCapsule body fits nano tanks — hides behind plants and decor\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eOver-temperature protection — shuts off if water exceeds 36°C, resumes at 34°C\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eDry-run auto shut-off (upgraded model) — sensor cuts power when water level drops\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003eTouchscreen adjustable model available for custom temperature targets\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003ePlease use a 5V\/2A adapter for optimal heating performance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"http:\/\/detail.1688.com\/offer\/690196194723.html","offers":[{"title":"Constant temperature26℃【Applicable2L Water】","offer_id":47883333140715,"sku":"LUMO-V-00047","price":15.99,"currency_code":"USD","in_stock":true},{"title":"Constant Temperature26℃+Disconnect from water and electricity【Applicable2L Water】","offer_id":47883333107947,"sku":"LUMO-V-00048","price":18.99,"currency_code":"USD","in_stock":true},{"title":"10Touchscreen 【Applicable2L Water】","offer_id":47883333206251,"sku":"LUMO-V-00049","price":21.99,"currency_code":"USD","in_stock":true},{"title":"15Touchscreen Temperature Control【USB】【Applicable3L Water】","offer_id":47883333271787,"sku":"LUMO-V-00050","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/9122\/5067\/files\/01_d0fcc69d-9201-4730-8782-bee77dc7b983.png?v=1772466316","url":"https:\/\/lumopetshop.com\/products\/mini-usb-aquarium-heater","provider":"Lumopetshop","version":"1.0","type":"link"}
