Review on 🏕️ The Ultimate Coleman OneSource Rechargeable Camping System: Unleash Adventure-Ready Power! by Kerri Houston

Not only does it work with many air mattresses, it's a good little battery if you only need one battery when you're camping or on a trip. It slides out of the pump easily and is slightly larger than a small LED flashlight. The battery itself is 4500 mAh. So many phones will be fully charged once, some will not be fully charged, but others, like the iPhone SE2020, need to be fully charged twice, with an additional cost. Another reason this product deserves 5 stars is that while it charges faster, it at least charges via USB-C. The cable that comes with it is also of good quality. The ports are also covered with small flaps to keep dust and moisture out. If you just want the battery there are better options with more capacity, but if you also want the functionality of the pump accessory then having the battery available as a standalone product is a nice bonus.
