Review on Versatile Portable Clip-on Fan: 12000mAh Quiet Small Desk Fan with LED Lights, Hooks, & 60 Hours Battery Life - Perfect for Camping, Stroller, Tent, & Home Use! by Joe Pettigrew

This tool was used on a 5 day hunt in freezing temperatures as low as 23 degrees below zero. At camp it was used constantly to circulate heat in our Seek Outside 4 person wood stove tent. Only had to be used at low speed as it worked better than we expected. During the excursion times, the tent and equipment were lowered to the outside temperature. Leave the heating on when you return and the fan had no cold issues. The battery lasted almost the entire trip. One charge of the battery and there were no problems with it. In the end she exceeded our expectations and two other members of the group also order her for their tents and boat. Good product. highly recommended.
