This JisuLife Ultra 1 does have two 4,500mAh cells, but they're connected in series! So the batter capacity of this is 4,500mAh, but the energy capacity is the same, whether it's connected in parallel or series (33.3Wh)! But over all one of the best and reliable turbo fans out there! My Ultra1 is gonna be with me in 8 days. It dropped to 70% fan speed due to safety reasons!
And I think the reason why they connected the cells in series is to minimize power and heat losses through the wire with a higher voltage of 7.4 volts, as it draws less current at the same time for the same power output!
@daineramosquitco5816 Hello there! Thank you for your input! Yes they are connected in series, like almost all devices that have more than 5000 mAh. Jisulife advertice this fan as a 9000 mAh fan. You made a good choice to buy this fan, i use my fan every day. 😃
@daineramosquitco5816 That sounds resonable, that the batt is connected because of what you said. Yes, i understood that the speed go down because of safety reson... 🫡
@@mashmallowsnowy3328 Thank you for looking at my video! 😃 I totally understand how you thinking about sponsored videos, i feel exactly the same! Enjoy your new fan, if you have some question about it, just msg me. 😇😇😇
@@mr.gaming1635 Hello there! 😃 The fan go down in speed because of the safety protection in case of overheating, so the overheating system is really working! 👍👍👍
@@mr.gaming1635 Hello there! Thank's for your question... I charge the fan with it's max 18 - 19W, but of course you can charge it with a lower W too, but it will take longer time until fully charged. 😇

@@solitaryslacker6351 exactly! You can use 100% for a few moments and then it automatically drops down once your sweat has dried up!
Hehe yes that's true 😂@daineramosquitco5816
Hope that so many positive videos are telling the truth instead of being sponsored or something😂My fan is on its way ! Thank you for the video

Wow, nice video I like the fan. 😊😊😊
Thank you so much 😃😃😃
What do you think why the fan level go down from 100 to 70?
