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 purchased this as a fan for car camping to move the air around and it works beautifully for this purpose. It's not noisy and does hold a charge very well.

Has some weight and feels like a solidly made fan. A little beefier than what I want for backpacking but perfect for car camping. Fairly quiet and pushes good air. Downside is that it has a microUSB port. Otherwise, good product.

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

Fan is excellent, small smooth and powerful, however, the fan doesn’t hold positions, they didn’t design the strap right. Product incomplete but very good fan!!

Love this fan. Rechargeable, small light weight, with clip to hang is you want. We use it camping.

This was the perfect addition to our Oklahoma camping trip. It's whisper quiet and lasted on low the entire night! GREAT PURCHASE!

Great fan. Loved everything about it. But who cares about that if it only lasts 6 months.6 months of normal home usage, and it just makes noise now.I want a new one. We’ll see if that happens.
