JisuLife Handheld Fan Pro1 S vs JisuLife Handheld Fan Ultra2

What you'll actually notice

Both sit above the basic five-speed JISULIFE handhelds, and both give you 100 speed settings plus fast USB-C charging. The difference you will notice is how far each product moves beyond ordinary personal cooling.

The Pro1S is still a focused handheld fan. JISULIFE states 9.0 m/s maximum wind, up to 40 hours runtime and 18 W fast charging for the 5000mAh family.

The Ultra2 turns the fan into a broader utility platform: 9000mAh battery, 17 m/s stated maximum wind, up to 25 hours runtime, 18 W two-way charging, power-bank function, utility/SOS light and magnetic attachments.

So the practical split is not "good versus better". It is high-output personal fan versus high-output fan plus utility tool.

What changes the choice

Do you actually need Ultra2's higher output ceiling?

JISULIFE states 9.0 m/s for Pro1S and 17 m/s for Ultra2.

That is a large manufacturer-stated difference and clearly positions Ultra2 above Pro1S for burst output. PIQSY does not translate it into a proportional cooling claim or room-coverage advantage.

For ordinary close-range use, Pro1S may already provide more output than you routinely need. Ultra2 becomes easier to justify when stronger bursts of airflow are part of the task rather than an impressive headline.

Does the 9000mAh battery do another job for you?

Ultra2's larger battery supports two-way 18 W charging and power-bank use. That gives the extra capacity a role beyond fan runtime.

Pro1S is more focused: fan first, fast charging, no broader battery-tool proposition.

If you travel, work outdoors or already carry backup power, Ultra2 can replace another device. If not, the larger battery is mostly supporting a more extreme fan platform.

Why does Pro1S have the longer runtime headline?

Pro1S is stated at up to 40 hours while Ultra2 is stated at up to 25 hours, despite Ultra2's larger battery.

That is a useful reminder that battery capacity alone does not predict endurance. Motor output, control strategy and the operating mode all matter.

Both figures are manufacturer ceilings. Neither should be read as maximum-speed runtime.

Will you use the tool functions?

Ultra2 adds magnetic flat and round nozzles, a utility/SOS light and other accessories.

Those features make sense for equipment cleaning, travel, outdoor tasks or situations where concentrated airflow has jobs beyond comfort.

If personal cooling is the only requirement, Pro1S avoids carrying capability that may never be used.

Does the higher noise envelope matter?

The manufacturer range for Pro1S is 53–80 dB. Ultra2 is listed at 65–102 dB.

These are manufacturer specifications, not PIQSY-controlled tests, but they reinforce the intended trade-off: Ultra2's extreme top end is not a silence-first proposition.

If quiet close-range use is a hard constraint, buying the most extreme output tier may work against the actual requirement.

Can weight decide this comparison?

Not cleanly. Ultra2 is at 295 g.

PIQSY deliberately does not assign a Pro1S weight because official material and battery variants expose different values.

So this comparison does not invent a gram-for-gram winner. If low known carry weight is your primary requirement, Life10 S has cleaner evidence.

Does the 295 g Ultra2 body change the portability equation?

Ultra2 is at 295 g, which is still handheld territory but makes the larger battery and tool platform physically more substantial than a basic travel fan.

Pro1S does not have a clean exact-variant weight, so PIQSY does not manufacture a precise weight comparison.

The useful decision is therefore qualitative: Ultra2 asks you to carry a verified 295 g multi-tool package because its extra functions justify it. If those functions are not needed, the more focused Pro1S proposition becomes easier to defend.

The practical choice

Choose Pro1S when you want a serious handheld fan with fine 100-step control and high stated output, but do not need the power-bank or utility-tool layer.

Choose Ultra2 when the fan is expected to do more than cool you: stronger burst airflow, emergency/utility lighting, power-bank duty or nozzle-based tasks all give the larger platform a reason to exist.

If those extra jobs are hypothetical, Pro1S is the more focused purchase.

When to choose JISULIFE Pro1S

• 9.0 m/s stated maximum is already enough.
• You value 100-step control.
• Up to 40 hours stated runtime suits your usage.
• 18 W fast charging matters.
• You want a fan first, not a fan/power-bank/tool hybrid.

When to choose JISULIFE Ultra2

• 17 m/s stated maximum solves a real high-output need.
• A 9000mAh battery doubling as a power bank is useful.
• Utility/SOS lighting or magnetic attachments will be used.
• You accept a higher manufacturer-listed noise envelope.
• Up to 25 hours stated runtime is sufficient for the way you will use it.

Choose neither when

Choose neither if your real priority is the lightest simple travel fan; Life10 S has a 208 g weight.

Choose neither if hands-free cooling is the hard requirement; Neck Fan Pro1 changes the form factor rather than escalating handheld output.

PIQSY conclusion

Choose Pro1S when you want high-output personal cooling without paying attention to a broader utility platform. Choose Ultra2 when maximum stated output and its battery/tool functions solve additional real jobs.

Ultra2 is not automatically the better fan because its numbers are larger. Its extra complexity only earns its place when you will actually use it.
