Part of a system that powers outdoor gear, the Coleman OneSource 4-Person Camping Dome Tent with Airflow System & LED Lighting lets you enjoy time outdoors with friends and family comfortably. An integrated fan refreshes the air in the tent 6 times per hour to reduce humidity, and LED lighting offers warm diffused light throughout the tent. The lithium-ion battery can be conveniently recharged from wall outlets, vehicles, universal power packs, or other OneSource batteries with the included USB cord. Bonus? The OneSource battery helps eliminate the need for multiple power sources by letting you charge external devices, like smartphones or tablets (not included), through a USB port, even while powering gear. One system, one source, power anywhere!
