It is ideal for betta fish tanks, shrimp bowls, small turtle enclosures, and pet water dispensers. For larger tanks (up to ~5 L), you can use two heaters simultaneously — each connected to its own dedicated USB power source.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do I need a special charger to power this heater?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, you must use a \u003cstrong\u003e5V 2A USB charger\u003c\/strong\u003e or compatible power bank. Using a charger with insufficient current (less than 2A) will result in poor or no heating. The heater will not damage your charger, but performance depends on having the correct power output.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know if the heater is working or has reached the target temperature?\u003c\/h4\u003e\n\u003cp\u003eA: The heater uses a two-colour LED indicator. A \u003cstrong\u003ered light\u003c\/strong\u003e means the heater is actively warming the water. When the water reaches \u003cstrong\u003e26°C\u003c\/strong\u003e, the light switches to \u003cstrong\u003egreen\u003c\/strong\u003e and the heater pauses — this is normal operation. It will resume heating (red) if the temperature drops below the set point.
