مدفأة ميني لحوض الأسماك تعمل بـ USB

Excellent product, I have already tested it and it is maintaining the water at 26 degrees. It has an indicator light that turns red when heating and green when the temperature is reached.

A good small heater, suitable for long-distance winter transportation of fish, powered by a USB power bank.

This mini aquarium heater works impressively well for its size. it maintains a stable temperature right around 26°c, which is perfect for small tropical setups. it’s compact, easy to install, and doesn’t take up much space. reliable and consistent, it’s a great choice for nano tanks or small aquariums.

The product arrived within the expected timeframe and was well packaged. The quality matches what was advertised, and it has been functioning correctly so far. It met expectations and fulfills its purpose well. Interesting cost-performance ratio. I recommend it to those looking for something practical and efficient.

It arrived with the box very damaged, but the product was well protected. It's quite small, as described on the seller's page, and will be perfect for the Betta's aquarium. I haven't turned it on yet. I recommend the product and the seller.
