Review on 💨 innobay USB/Rechargeable Personal Fan with LED Light - Quiet & Powerful (4-inch, Black) by Tim Woods

I bought this fan primarily for running on a treadmill and I didn't expect it to be that efficient. But hey, that would be better than no fan at all, right? MAY BE. This fan blows full - it seems to be moving more air than my Vornado Flippi V8 desktop fan. Probably because the airflow is much more concentrated. With just the one included 18650 battery, the fan ran for the 60 minutes I worked and still had a decent charge afterwards (about 3.79v compared to 4.15v on a full charge for standard lithium -Ion rechargeable batteries 18650). ). In addition, the fan runs only via USB. So if you have a high capacity battery, you don't even need a 18650 battery in it: you can just plug it in and run it for a LONG TIME! If you want, the battery will also charge when you run at high speed via USB. I then took it to the San Diego Safari Park and although I was wearing a vest and long sleeve shirt my buddies started getting wet around noon when it was about 75F but I had all my gear with the fan running and I did it doesn't even wake up! Towards the end of the day my friends started fighting over this simple $20 gadget they ALL wish they had. In addition, the thing is small and light. So light it could explode if you leave it high up on a table. It won't sit on its own, but if you nudge it lightly on the table when it's at its height, it will explode. That's how strong he is. At the same time, taking it with you when hiking or strolling through some amusement parks is not a problem at all. For $20 I highly recommend it! In addition, there are cheaper alternative versions of this brand with a lower capacity battery. I'd say do yourself a favor and grab this version which comes with a good quality Samsung 18650 rated at around 2200-2400mAh. It will last for many more charge cycles, not to mention a few more minutes when you really need it. I have a bunch of Panasonic 18650 3400mAh for my flashlights and I've never had any complaints about the battery life with any of them. From a technical point of view, the fan can work with both button and 18650 button batteries (there are two types) due to the spring on the negative pole. The fan blows up again!
