Odoland 10000mAh Camping Rechargeable Fan with Hanging Hook Carabiner, Portable Battery Operated Tent Fan, Quiet Strong Airflow, Outdoor Small USB Desk Fan for Picnic Travel Barbecue Fishing

UPDATE:This great little fan is still going strong after 6 months of 24/7 use! Great little trouper—durable and well made. I use high capacity USB battery packs to keep it going in my small outdoor greenhouse. Its own battery has significantly shorter battery life after 6 months though, which I see if I forget to swap out the battery packs. When new, its internal battery would operate for 12+ hours on highest fan speed , but now, after 6 months, it can run the fan for more like 8 hours.——————————————————————————————————————————————————-Wow—for me this little fan is worth its weight in gold! Very well constructed and well made, its air output is just incredible for its size—truly impressive. I use it inside my very small (3’ x 2’ x 60”) outdoor “shade shack”, where I grow orchids. The shack gets covered at night with a custom poly cover that fits like an envelope, and velcros tight. I use this fan mounted right over (about 5” above) a very small outdoor space heater that is pointed straight up and set on low heat. This fan is connected to a 50000mAh USB power bank, and its rear inlet sucks up all of the heat from the heater directly below it and sends the warm air out over the interior of the covered shack. It works great and keeps my orchids comfortably at 58F-60F during our California nights (lows occasionally in the mid 30’s)I have to set this fan on low, speed 1, as anything higher causes too much circulation and too much heat rises to the top of the shack. Also the higher speeds tend to pummel the more delicate plant leaves, even though its output is directed away from direct contact with any plant! This from a tiny 4” fan blade!The one caveat, drawback (and I read this in other reviews), is that the way it hangs is unjust-able. You have to work around its one direction fixed hanging position—though you can angle the fan head up or down. For my shack I had to wrap wire kitty corner within one corner my structure so that the fan could blow diagonally across the cross apex of the shack. Other fans I tried were much more easily adjustable with mounting, but had abysmal air flow output compared to this fast blowing monster, even with it only on low speed 1.The battery is as advertised, and when not connected to the USB power bank, in my testing it went for over 8 hours on speed 2; it even has power left, so I think the advertised 8-12 hour battery life is quite accurate, maybe even longer on the lowest speed 1.I can see this being very powerful and beneficial (probably on speed 3, high) for small enclosed spaces like tents or hunting blinds (and of course, mini greenhouses). Highly recommend!

I hang these in my little chicken coops at night and charge them during the day. Been going strong for a year now. They run all night and keep my girls from overheating in the hot, humid south Texas nights.

These put out a good amount of air, and did a decent job of keeping me cool at night. Make no mistake. These are power eaters. If you want to run them all night you do need a good battery bank to plug them into. A 10k mah one worked for one of them all night, about 9pm to 6am, and then about another hour more, so about 10 hours total use on high.

They are very small. It took me some time to figure out the best way to hang them in my small SUV daily driver. I have these elastic bungees that are about three feet long each, they hold the fans pretty steady and keep them close to the ceiling. If I use the loop/pull on the fans, they'd be bouncing a lot when I drive. Also, I have them connected to small solar panels on my front windshield so they are always charged up.For my Suburban camper, I use much larger fans.

I bought this to put on outside screen of my pet carrier, was best idea and product for flights with my dog.

The description AND instructions mention an indicator light. Mine does not have this, anywhere. Works okay, but no way to tell if charging, low battery, etc.

I don't think I'll ever need to go above "low" .. I almost wish it could go lower! It lasted at least 8 hours until I shut it off in the morning. About 38 dB from 6 inches off to the side on low. About 40 on medium, 42 on high.I got a 2 pack and both work great.I have read some folks on get 1 that works, not my case.Took one apart to confirm real capacity: 10,000 mah is a strong claim. It is quite plausible it has 10k mah, or close. There are four long cells in a 2x2 arrangement.

Purchases in January and one is dead and not turning on. I’ve left it on the charger for a few days using different cables, cubes and outlets but it won’t charge unfortunately. It’s dead after 3 months. Hope the manufacturer does right but who knows
