Just Add Water Here is a waterproof, battery-powered portable shower that can serve multiple purposes indoors or out. By drawing water from virtually any bucket, basin or sink, the Ivation portable shower system turns a pool of water into a gentle shower-like stream on demand. This level of mobility and shower-anywhere capability is great for many uses such as on-the-go showering for campers and hikers; accessible poolside or beach showering; gentle bathtub showering for toddlers/babies, eliminating the need to use the strong overheard shower stream; an easy, portable water stream for home car washers; outdoor horse cleaning, and even house-pet washing in the bathtub. Rechargeable via USB For a true go-anywhere shower, a built-in rechargeable 2200mAh lithium battery powers the Ivation portable shower for up to 60 minutes on a single charge. Charging is easy via USB connection to a computer or laptop, or with a 12v car adapter (Not Included). Couple that with the included suction cup and hanging hook, and you've got a shower ready when you are. The suction cup works on most flat surfaces, and allows parents to use both hands when showering their children. Use the S-shaped hook when camping to hang the lightweight, 1.4-pound Ivation showerhead on any nearby branch, and voila! You've got yourself a modern "crying tree." Get clean. With cleaner water. The Ivation portable shower features a built-in water filtration system that cleans the water while the shower is in use. This does not affect the flow of water, which runs through the 6.5-foot hose at a consistent 2.5i/minute. For the camper or hiker, the filtration system in a brilliant innovation, turning lake or pool water into clean shower water.
