Handheld Fan, Portable Fan, 4000mAh USB Rechargeable Personal Fan, 180° Foldable Mini Desk Fan with 6 Wind Speed, LCD Digital Display, Lanyard as Neck Fan, Ultra Quiet, Pocket Size for Indoor Outdoor

BLUF (Bottom Line Up Front) Very effective, value priced, dual purpose Fan/Battery Bank. What a great idea! A personal fan that can keep you cool for 5 - 16 hours (claimed) depending on which of the 6 speeds you choose (so it COULD run all night) and is claimed to recharge in 1.5 hours (Ill have to see if it really can use a Fast charger pulling all 2.4 amps - which would then take 1.67 hours to put in 4 amp hours). Also a neat feature is the power meter that shows you how much energy remains in the battery. It comes with a soft neck lanyard and a USB-A to USB-C charging cable, you provide the charging block. So - as originally received, it came charged to 68%. I connected it through my digital tester to a USB port rated for 3 amps, but this device only pulled 0.85a. So I moved it over to my QC3 port - rate dropped to 0.82a. At 0.85a going from 69% (when I started my watch) to 100% (delta = 31% or 1.2 aH) Id expect charging to be finished in 1.47 hours. After 20 min, charging had dropped to 0.70a (74% charged). I removed the USB tester and directly connected the fan to the power supply (5v 3a port). 10 min later charge had increased by 2% with 22% remaining till full = estimate now is 110 min to full charge. FINALLY at 100%, a 31% overall increase, took 2 Hr 15 Min. So No - you cant fully charge this from empty to full in 1-1/2 hours as claimed. Rundown testing started at 100% battery and fan level 6 (High - moving a LOT of air). 1 hour later charge remaining was 76% (delta 24% suggesting a little more than 4 hours at full speed). Switched to Level 3 (?1/2 speed) - still moving lots of air dropping 16% over 82 minutes suggesting an 8.5 hour run-time at that speed. Then switched to Level 1 - still an effective breeze - dropping only 6% over 3.5 hours - suggesting a 58 hour run time at low speed. YMMV. Please note the above analyses assume linear battery charge/discharge characteristics which may not necessarily be the case.

This fan is very interesting! It looks a bit odd compared to the usual rechargable fans, but its easy to see why as you look it over. First, I really like the the fact that it has 6 speeds. The LED panel shows the speed chosen and then switches over to the percent of battery charge left. When charging with a typical USB-C cable (included), the LED is also on so you can monitor the charge. There is also a geen indicator on the screen that flashes while taking a chrge and then goes solid when done (along with the LED showing 100 percent). The fan folds up and doesnt take up much space and then provides several ways to have it set up. Another unique feature is the included lanyard that clips on so this fan can be used hanging around ones neck while on the go or working around the house. It took a bit to figure out how the lanyard attaches and I finally figured out that the ends have to be positioned sideways to slip into their attachment slots. No mention of this fact in the manual. It could be easy to break off the attachment points if forced in the wrong position! Pay attention! Last cool thing: There is a USB-A port on the opposite side from the USB-C charging port. Why?? Because this fan can also function as an emergency power bank! I believe the battery is only 5000Mah one, but in a pinch, that would give most phones enough of a charge to make a dead phone able to call out, or to recharge earphones, etc. As I said to begin with, this fan has some very unique features and is well worth the cost, IMHO!

I like this fan a great deal. It is pretty quiet, even at the highest speed. The head tilts back 180 degrees and stays in the position where you put it. This makes it easy to hang from your neck as well as put it on its belly on the table. It has 6 speeds and the last 2 are very definitely moving a lot of air. There is not much difference in air movement between the 5th and 6th speeds, but there is still a little bit. Hanging it around your neck angling the head back so it points at your head, the 5th and 6th speeds might be a bit much for some folks. The lanyard is soft and comfortable, not sure how long it will last, though. It is also a little tricky on connecting it to the fan cage. The stem for the plastic pins is flat on one side and narrower than on the other side. So, be sure it is in the narrow position when connecting it to the fan. The cage has a slot on each side for the plastic pin to fit. The little rim of copper trim is nice. Te display will flash the speed for a second or two, then goes to the battery charge. When charging, there is a green lightning bold on the side of the display to let you know it is charging. Mine came with a 68% charge. I have not used it as a power bank. The power bank uses a regular USB connector. The charging connector is a USB C and it does come with a charging cable (USB to USB C). This should be very nice to have when the summer starts heating up.

Blows a good amount of air for how small this is. Mine did not come with a lanyard, unfortunately. The built in USB A port for charging is a nice bonus for emergency charging. The battery life is displayed in percent, which is quite nice. A lot more information than a few leds most other battery powered devices use.

Best portable fan Ive had and Ive bought a lot in the past. Battery lasts a long time. Build quality is good. Different fan speeds are great.

For the price I wasnt expecting much....but I am SOOOO happy with this little personal fan. It can fold where I can place on my work desk and have it blow right on me. I traveled with this and just tucked it into my carry on. It is very sturdy...NOT cheap plastic as I anticipated. I am very happy I purchased this fan.

I didnt know how much I really needed this little rechargeable fan until I actually had it! This is a small, lightweight fan that is great to carry around on hot, humid days to give you a little relief from the heat. Nice powerful air and easy to flip and tuck in your purse or manuever for comfort

This fan is versatile with many modes: handheld, neck, or mini desk fan. It is also very compact and portable, making it useful for indoor and outdoor use. Secured and off to the side of the dashboard, it makes a great replacement for the kaput car AC. I did wonder about how loud this unit may be, but found that its barely audible even on the highest speed setting, making it perfect for use in quiet environments or settling into bed. The battery charges quickly (charge level displayed conveniently as a percentage), but also drains fairly quickly at the higher setting. Keeping it at a 3 out of the 6 settings really works best for personal use. The compact and sleek design makes it easy to pack or toss in a bag or backpack and take along. The neckstrap situation may be a bit questionable - doesnt seem super-secure, and do you really want a fan in your face and hanging around your neck? All things considered, pretty happy with this model and pretty much a fan.

It came with about 23% battery life out of the box. The first time I tried to charge it, it would not charge at all. I tried a different cable to see if the cable it came with was deficient, but it still would not charge. Waste of money.

This is so what Im looking for, Im yet to use it for a long time but I love it already, will update after use
