Stay Comfortable Through Every Heatwave
Cuts Your Cooling Bill By Up to 90%
A window AC pulls around 1,000 watts. Jiuberry pulls 2 to 7. Run it instead of cranking the central AC, or use it in place of a window unit. Either way, the difference shows up on every summer bill. And it costs a fraction of what a $800-1500 AC runs you upfront.
Cools Your Space in Just 30 Seconds
Unlike traditional fans that simply circulate warm air, Jiuberry uses advanced CoolCore™ technology to produce a noticeably cooler airflow in as little as 30 seconds. You’ll feel fast, refreshing relief from the heat.
Safe, Quiet & Ready in Seconds
Three things a window AC will never give you:
-
Zero Blades for Zero Worries
Air moves through a sealed vertical channel, not past a spinning rotor. Nothing is exposed for fingers, paws, or curious toddlers.
-
So Silent You'll Forget It's On
Brushless motors have fewer moving parts, so they make less noise. It’s so quiet, even your baby will sleep through it.
-
No Installation Required
Plug into any USB-C charger or run it on battery. Place it on your desk or stick it on the wall.
Smart, Simple, and Built for Comfort
Bladeless Tower Design
Air moves through a sealed tower, not past spinning blades. The brushless motor inside pushes more air per watt than a regular fan. So you get a stronger breeze on a fraction of the power.
3 Cooling Modes
Three speeds, three jobs. Low is gentle enough for overnight. Medium is for working at a desk or sitting on the couch. Turbo is for when you walk in from outside and want cold air on your face right now.
Cools For Up To 12 Hours
Use it plugged in or on the go. The built-in battery lasts up to 12 hours, so it keeps cooling from desk to nightstand to porch without hunting for an outlet.
CoolCore™ Tech
Our engineers worked hard on making a small device that is capable of producing cooler airflow while not racking up your bill. CoolCore™ was the result.
Instant Cooling in Just 3 Steps
Plug It In
Plug into a USB-C charger or run cordless. Set it on a desk, nightstand, or wall.
Choose The Mode
Choose between low, medium, or turbo mode to match the temperature around you. Set the timer.
Enjoy the Comfort
Feel the temperature in the room drop in just 30 seconds.

The realy low power bill really surprised me!
Two units running on the desk and the nightstand. Bill went from $340 in August to $190 this year. That’s a $150 difference for two months in a row, easy.

I can finally sleep peacefully at night
I used to wake up sweating at 3 am and would crank the AC up. It would takes hours for it to cool the house down and the bills were insane. Now I just turn this on at bedtime and it works through the whole night and I stay nice and cool and don’t wake up anymore. It really is super quiet.

Can keep it running next to my cats without worries
Was worried about leaving a fan running with two cats but the bladeless thing solved that. They sleep right next to it. Quieter than my old box fan and uses way less power.

Cools so good I ended up buying four
Now I have one for the office, one for the bedroom, one for the kitchen, and one for the guest room. It’s insane how that’s still cheaper than getting a window AC, and I can move them around as needed. Now I feel comfortable everywhere I need :))

Doesn't even show up on my work mic
I take calls from home all day and this thing is silent even on turbo. Try doing that next to a window AC. Love the cooling.

Saved me from overheating
Sadly, no AC is allowed in our dorm despite the summers getting really really hot here. This little thing literally saved my life. Always keep it plugged in and it keeps the room pleasantly cold.

You can even place it in the garage it works
I got one for the woodshop where there’s no AC and I can’t believe I didn’t get it sooner. I just plug it into the outlet by my work light, and I can finish a project in August without quitting from the heat.

Helps keep my kid’s room cool and fresh
Super glad it has no blades or moving parts since my two-year-old sticks her fingers in everything. Now I don’t have to worry about her getting hurt and she doesn’t have to suffer through the heat. Plus she actually naps because of how quiet it is!

Cheaper than a window AC by miles
I ran the math. My old 5,000 BTU window unit pulled around 450 watts. Jiuberry pulls 5 on medium. I left it on for a month straight and barely noticed it on the bill. Definitely the solution I was looking for 💯

The battery runtime is no joke
The battery actually lasts!! Most cordless stuff I had died in two hours and honestly didn’t cool much. This one ran from breakfast through dinner on low and I felt great the whole day!

Mom finally stopped worrying about bills
Bought one for my mom (76) who lives alone and won’t run her AC because she’s worried about the bill. She actually uses this one and she stopped complaining both about the heat and the power bills!

Saves so much money because it only cools one spot
My old approach was just to crank down the central AC just to keep my home office cool. Stupid and super expensive. Now I just point Jiuberry at my chair and let the rest of the house sit as is. And if I go to any other room, I just take it with me, and it cools it down fast. Way cheaper.

Thank god it works right out of the box
Took it out of the box, plugged it in, and it started working immediately. Would not have bothered with it if I also had to install it

You can even take it with you it’s pretty small
Threw it in my carry-on for a work trip and used it in the hotel because their thermostat was stuck. Cannot imagine staying anywhere hot without it.

The three speed modes actually feel different
To me, most fan speeds kind of feel the same. Esp since they just swish hot air around and don’t actually cool it. With this one, the intensity and coldness are actually different depending on the mode I pick! Love blasting turbo when the days get really hot and humid.

The wall hook is honestly genius
Stuck it on the wall above my desk with the included hook. No holes, no drilling, frees up the whole desk and the cool air drops right onto me. Didn’t expect to like that as much as I do haha

“Jiuberry was rated the best low-energy portable cooler of 2026.”
Meet Our Expert
HVAC Engineer
I get asked about portable coolers all the time and most of them are just rebranded fans. Jiuberry is the first one I’d actually recommend to a homeowner trying to cut their summer bill. It drops the air temperature fast, runs on almost no power, and doesn’t need installation. For anyone cooling one room instead of a whole house, this is the right tool. I even keep one on my own desk.
