A 5v USB "squirrel cage" blower fan. Dimensions: 52x40x10mm. The total wire length is about 40 inches in length. Asst USB cable colors. I am Willing to shorten leads on request. These have shown to be effective and compact cooling & ventilation fans for mascot/fursuit heads or other cosplay outfits. Simply attach to any USB power pack and go. The output is in the flat 52 mm edge. I have used them on dollar store acquired 2xAA to 5v USB packs (ask in message if you would like to acquire one/where to get). Running them on bargain batteries they have run 6+ hours. They should run much longer on name-brand batteries. [SPECIAL] this batch coems with a pocket juice 2000mah pack
I originally made rigs like this for myself and a few others. I use set ups like this myself. They are very effective and quiet for their size. These are typically quiet enough to run non-stop while in costume without making it harder to hear your surroundings. They are low vibration, so you don't get that irritating 'face buzz' some fans cause. The focused output makes them put out faster and cooler air. The focused stream seems to deliver cooler fresh air right to you more effectively than fans of similar size and output (and some larger output fans I have experimented with). These can also be installed as exhaust fans to shed heat and draw cooler air in form other locations. They can easily be tucked under the jaw sets in many fursuit heads. This makes them out of sight and out of the way. Several have found the cable length handy to hang the battery on a tail belt (fur suits) under suit or hidden in a pocket while in partial or other costume.
Install them with the cable also attached around/behind the heat shrink joint to protect the smaller wires and connections of the fan from accidental damage.
