Features

  • SUPER MINI SIZE This small aquarium heater is thumb size - only 2.36 (6cm) in length. 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 1-2 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.

  • Makes fish happier
Size: 20W
The media could not be loaded. I can instantly tell that my fish are so much happier with warmer water! They're swimming around and exploring my tank more often instead of laying on the floor of the tank. They like to hang out near the heater to feel comfy. It makes no noise, heats the tank to the set warmth quickly, has great suction, and is very sturdy. It doesn't take up much space in my tank. As shown in the video, however, there is a difference in temperature shown on my external thermometer and the temperature set on the heater. It usually hovers around 73~74°F. My fish are still happy with this temperature though, so it isn't much of an issue! ... show more

  • You have to get an external thermometer. Otherwise it works good if you've got the right wattage.
Size: 10W(USB)
The thermometer built in to this heater will lie if you have a wattage that is too weak for the size of the bowl / aquarium. We originally bought the 10W for a 1 gallon then we got a 5 gallon and it started getting cold at night. The temperature was saying it was at 80 however the fish was *very* stressed out and the water was cold. We got an external thermometer and found the water was around 74 when this heater said it was at 80. When we got the 30W it started doing really well, keeping it at 80 and saying it was at 80. This heater works really well and is incredibly small when you've got the right size wattage! ... show more

  • Nifty, Fun Aquarium Heater!
Size: 10W(USB)
I got my first of these Heaters near a month ago for my 1gal. Betta bowl. Nifty (neat and easy to use), it's been a perfect fit for the compact bowl space, with a digital control combining thermostat (to set the desired heater temp) and thermometer (to show the actual aquarium temp). Loved it so much, I then got a second one, this for my cylindrical 2gal. community tank which is home to six Guppy/Molly/Platy fishes. Yes, it is overcrowded but I closely monitor the tank's water quality and other parameters as well as the fish behavior there. And all the guys are doing well, as shown by their feeding habits, mobility, even schooling activity. Relying on these Heaters for keeping both of my minimal aquaria at an optimal 80°F I've felt confident that all is well. Until the last day or two… my apartment has cooled somewhat from its usual 75°F or so down to 68°F, nothing drastic. Yet the two heaters now seemed taxed to hold their spaces at the 80°F I've set. Each aquarium now hovers at 74°F, shown by the controls of each heater and verified by strip thermometers, one on each aquarium located up against the heater (at least for the Betta bowl). This is a mildly troubling issue on which I will update this review if warranted. ... show more

  • Tiny yet mighty!
Size: 20W
Sam, our unexpected Betta fish birthday gift for our 7-year-old, quickly became a beloved member of our family. To ensure his happiness and comfort in his new home, we had to learn the ropes of Betta care. It was surprising to discover that these little fish, often sold in deli containers at pet stores, require a considerable amount of care. During our research, we learned that Betta fish thrive in water temperatures between 78 to 82 degrees Fahrenheit, and achieving this meant we needed 5 watts of heating power per gallon. That's why we found the 20-watt heater to be a perfect match for our 4-gallon tank. This compact heater was an ideal solution for our uniquely shaped round tank, where our only option was a fully submersible heater. Many other models we came across were bulky and had no suitable attachment points. However, this heater's strong suction cup allowed us to discreetly position it near the rim of the tank, preserving the tank's aesthetics. Not only has it maintained a consistent water temperature of a perfect 80 degrees, but it's also safe to touch, as Sam often swims close to it without harm. One feature we appreciate is the easily visible digital display, which helps us monitor the temperature and ensure Sam's safety. However, my one concern is the auto-shutoff setting, which is set at a rather high 97 degrees. Knowing that Bettas cannot survive in water temperatures exceeding 86 degrees, I can't help but worry about the possibility of returning home to an overheated tank. ... show more

  • Doesn’t heat
Size: 10W(USB)
I was so excited for my beta to have this as I’m sure he was. I take him out and prep the water + heater hoping I’m about to put my fish in the best little tank yet for it to never heat. The thermostat reader on it said the water was 75 I figured that was PERFECT I put my finger in it and it was pretty cold so I my old fish tank thermometer and lo and behold 42°. I was about to drop my fish into his new tank with 42° water. I was hoping with all the good reviews this would be the a good purchase. But so far I wish I went with gut and got him a bigger tank and a bigger heater. ETA: I am sending this one back for a replacement. I hope to change my review! ETA 2: I’m not even going to open the second one. My fish was very very sick due to the constant temp changing and messed up thermostat and unfortunately passed. If I could give this 0 stars I would ... show more

  • Works great!
Size: 20W
Update: the seller reached out and offered me a refund or replacement. I asked for a replacement and so far the replacement is keeping my tank at an adequate temperature for my betta. Great customer service! Hi, I’m just trying to contact the seller, not sure how, hoping they’ll respond. I bought the 20w for my 2.5 gal tank. I have it set for 80, and the temp is constantly showing 74-76, which is a bit too cold for our betta, and the red heating light it always on. It won’t just heat up to 80 and turn the green light on. We’ve been using this for about 5 days and continue to have this issue. Maybe I bought the wrong size? We also have a small glass thermometer that confirms the temp shown on the heater. Thank you!! ... show more

  • Works great.

We're using it in an outdoor (sheltered) pvc water tower (3-4 gallons) for chickens. I have it on a timer. Has kept water from freezing in temps as low as 10 degrees.
