It’s hot out there—oh crap, it’s hot out there—so in this quick review I took the JisuLife Pro 1S outside where the breeze is actually behaving, and I tested whether this “premium” portable fan is legit or just another gadget with vibes. Spoiler: I didn’t go in expecting much (first time using one like this), but I was pleasantly surprised. This thing is full metal alloy, feels durable in the hand, and it has an LCD display up front that makes it look extra cool and futuristic while showing speed and battery level. Performance-wise, the airflow is no joke. At around 50, it was so direct in my face that I genuinely started wondering if I had a big fan in front of me. I didn’t even bother maxing it out on my face because 100 would be too much in a normal environment. The battery is 5,000mAh, and JisuLife claims about 3 hours on the highest setting, plus it charges in about an hour and a half. My main downside: it’s not quiet once you go past 20%—at 50 you hear it ramp up, and at 100 it’s definitely audible. But if you’re active and need quick cooling on demand, this mini beast makes a lot of sense—if you’ve got the money for the premium price.
