All I can say is that I just love my jisulife pro1s, it can last me a whole day of mixed heavy use. If I’m just indoors it will last me 1 day and a half. Best purchase ever.
Life8 Plus is the undisputed king in battery life. Also, the design makes it much more suitable for children. The blades don't hurt when touched, and the closing mechanism protects the fan from serious drops. For general cooling needs like on an outdoor cafe here in the Philippines, it does the job well. The only problem is it doesn't stand sturdily, and wobbles on a table. My 2nd best is the Life5 Plus. Solely because the noise level is low, and the pitch it makes at max speed is much more pleasant than most of these fans. It's not that loud ringing noise you hear from the Ultra1, Pro1S and Life9. As for most disappointing one, it's gotta be the Pro1S as I've had 3 of them, and all started making awful noises after a few months. I think they are not built for rough handling and shaking on the backpack or when in a motorcycle. Overall, i recommend Jisulife fans as their build quality is great, and the advertised battery capacity is accurate. Trust me, I've done teardowns of several of these fans, and nothing comes close to their design and quality.
I tend to touch the fan blades by accident quite frequently when using the Life8 Plus, so I had to keep switching on the fan again. But that could just be me being more clumsy and careless Agree that the Life5 plus is relatively more quiet and the pitch is not as high. Quite surprised that the Pro1S didn't last that long for you. I am considering to do a drop test some time in the future to test the build quality
About the Pro 1S and the Life 9, they were very close, even with airspeeds! And it may be a hard choice to choose between the two fans for a lot of people! The Pro 1S was spinning at 15,000 RPM but the Life 9 was spinning at 40,000 RPM during the battery drain test in their maximum power! But overall they're excellent portable handheld turbo fans!
Thanks mate! Watched both your fan speed and battery drain videos (and I gave both a like). Next would be good to test noise level, as other commenters have requested, but also perhaps an overall chart mapping those 3 aspects - I have no idea how that would work in chart form but perhaps a radar chart? You would need 6 aspects, so maybe add price, weight, noise, airflow consistency (average drop in % every 10cm), battery life (high speed), battery life (low speed). Would be cool to visualise and compare, as everyone has different needs.
this brilliant test. thx for the effort. justb a suggestion can u do another test that's crucial to buying decision? a db noise lvl test at lowest and max speeds. this will be helpful when considering the noise to airflow ratio. keep up the good content!
Project Farm uploads yet another gem! hehehe Excellent work! Placed an order for the Ultra1 a few weeks ago thinking the 9,000mah battery would outlast everything. Seems I was wrong, and should have bought the Pro1S. Here in Philippines it gets really hot in April/May/June. Hopefully the Ultra1 still does the job in that heat without hearing protection. What's your view on that?
I think the Ultra1 is good for short bursts of very strong cooling, such as right after a sweaty workout. I actually use it to cool my phone and cameras when they get hot. But if you want sustained cooling, I think the Pro1S will be a better choice because of the really good battery life! 😊
If you just had to choose 1 out of all with all factors combined. I want to buy one for travelling etc especially for Singapore weather which one would it be
If cost is not a concern, i will go for the Life7 fan for the adjustable fan head and hands-free usage with the included neck strap. It has decent fan speed, and although the battery life is not the most outstanding, you can always keep it connected to a power bank for extended use. And, it has a removable vent for cleaning of fan blades
Amazing! I'm gonna be receiving my Ultra1 very soon, excited here! And bear in mind, the Ultra1 had significantly higher airspeeds than the others there, even at 70% fan speed! :O Even 25-50% is more than enough if you're using the Ultra1 too so yeah
How many hours do you charge you JISULIFE life 9? Ive been charging it for about 6 hours now and it is still blinking. Im currently using the cable that is provided

I can vouch for that! Love that the charging speed is also the fastest out of all the fans, at least in my experience.

Oh did you manage to test the fans yourself too? I didn’t manage to do the RPM test
which among these is your personal favorite?
The life4, life7 and pro1S :)
@@chevlimpro1s👍👌, super long battery plus fast charging
@ yes! 😊

Ultra1 has significantly greater airspeeds than the Pro1S and the Life9. And if you're using it outside the noise doesn't even matter
@daineramosquitco5816 sustained battery life > greater airspeed
can you rank the fans from quitest to loudest? thanks!
Do noise test plsss❤❤❤❤❤❤❤❤
Definitely considering about it! :)

Should i get pro1s or ultra?
Depends on what your use case is. For prolonged cooling, go for the pro1S. For quickly drying things, go for the ultra1
@@chevlim is ultra 1 still very good even in 1%
Life9 ❤ budget friendly , yet incredible and portable
Yeah if you don't mind the excessively small size :)
Yup, the portability really is amazing!
Amazing! I'm gonna be receiving my Ultra1 very soon, excited here! And bear in mind, the Ultra1 had significantly higher airspeeds than the others there, even at 70% fan speed! :O
Even 25-50% is more than enough if you're using the Ultra1 too so yeah
Absolutely right! Battery life is just one aspect, definitely need to weigh it against the fan speed
@@chevlim Definitely! I'll just give the Ultra1 the Upgraded Life 9 nickname, it suits it well
How many hours do you charge you JISULIFE life 9? Ive been charging it for about 6 hours now and it is still blinking. Im currently using the cable that is provided
3hrs and 6mins based on my previous testing.
Were you unplugging and plugging it in repeatedly to check if it is fully charged?
@@chevlim actually no, it was drained when I charged it. or maybe I wasn't using a fast charger adaptor?
Thank you!❤
You're welcome! 😊
Pro1s is worth it 😂
Absolutely! :)
How long would you need to charge to 100% the Ultra1?
2hr and 49mins in my testing!
