Verdict: After testing seven personal fans from $9 to $70, the Aecooly Slim Fan at $9.99 is the budget pick. For $1 more than the cheapest fan in the lineup, you get a foldable design, an ultra-thin profile, and a 24-hour battery life claim that’s the longest in the entire group. It’s not a powerhouse, but it’s the fan that proves you don’t have to spend $20 to get a real product. If budget is the priority, this is where your money should go.

What Makes a $10 Fan the Budget Pick Over a $9 Fan?
One dollar separates the Aecooly from the SWEETFULL at $8.99, and that dollar buys you a completely different product. The Aecooly folds flat — genuinely flat, thin enough to slide into a back pocket or a clutch purse. The SWEETFULL is a fixed shape that takes up more space despite being lighter. At BSR #5 in Personal Fans, the Aecooly outsells the SWEETFULL (#11), and in our testing the reason was obvious from the first thirty seconds of handling both.
Build quality for $10 is surprisingly decent. The fold mechanism feels sturdy, not flimsy. The hinge clicks into place with confidence. This isn’t a fan that feels like it’s going to snap the first time you open it.
Does the Ultra-Thin Design Hurt the Airflow?
Three speeds — same as the SWEETFULL, same as the JISULIFE F8. The airflow on the Aecooly is adequate for what it is. It’s not turbo. It’s not going to cool you down at an outdoor concert in July. But for personal desk use, light outdoor breeze, or drying lashes and makeup, the airflow does its job. In our side-by-side testing, the Aecooly pushed slightly more noticeable air than the SWEETFULL at max speed, though neither fan is competing with the turbo tier.
The slim profile does limit the blade size, which means there’s a ceiling on how much air this fan can move by physics alone. That’s the trade-off for the ultra-thin form factor — you get portability at the cost of raw power.
Does the 24-Hour Battery Claim Hold Up?
This is the Aecooly’s headline feature. Twenty-four hours of claimed battery life is the longest in the entire seven-fan lineup — longer than the JISULIFE F8 at 12-19 hours, longer than the turbo fans at 12-16 hours. In our testing, the low speed runtime is genuinely impressive. You can run this fan on low all day and into the next morning without reaching for a charger. On higher speeds the runtime drops, but the battery life at the gentle end is legitimate and useful for desk fans or overnight cooling.
No battery indicator on the unit, which is a miss at any price point. You’re guessing when it’s going to die, same as the SWEETFULL. Every fan at $18 and above gives you some form of battery feedback.
How Portable Is the Foldable Design?
This is where the Aecooly earns its keep. Folded flat, it’s thinner than your phone. It slides into a back pocket, a clutch purse, a laptop bag pocket, or a travel toiletry kit. The desk fan mode works by setting the fan open at an angle — stable enough on a flat surface, though it doesn’t come with an anti-slip mat like the JISULIFE Turbo at $22.
For someone who wants a fan that disappears when they’re not using it, the Aecooly’s form factor is unmatched in this lineup. The SWEETFULL is lighter but takes up more space. The JISULIFE F8 is more powerful but bulkier. The Aecooly folds flat and vanishes.
How Does It Compare to Spending $8 More on the JISULIFE F8?
The JISULIFE F8 at $17.99 gives you a power bank, a flashlight, stronger airflow, and the #1 bestselling position on Amazon. For $8 more, you get a meaningfully better product with bonus features the Aecooly can’t match.
But not everyone needs a power bank in their fan. Not everyone has $18 to spend. The Aecooly exists for the person who wants a functional, foldable, long-lasting personal fan at the lowest possible price point. And at $9.99, it delivers on that promise better than anything else under $15.
Who Is This Fan For?
Budget-conscious buyers who want a real product, not a disposable toy. Travelers who need a fan that folds flat into a carry-on. Desk workers who want a quiet, long-running background breeze. Anyone who needs a personal fan under $10 and wants the best possible option in that range. The Aecooly is the value pick — not the best fan, but the best fan for the money at the bottom of the lineup.
Final Verdict
The Aecooly Slim Portable Fan earns a 3.5 out of 5. The ultra-thin foldable design, legitimate 24-hour battery claim on low speed, and $9.99 price point make it the clear budget winner over the SWEETFULL. It won’t compete with the turbo fans on airflow, but it’s not trying to. For $1 more than the cheapest fan in the lineup, you get a product that actually feels like it was designed, not just manufactured. This is the budget pick.
