RinseKit Cube Electric Portable Shower
RinseKit Cube Electric Portable Shower
The RinseKit Cube is a 4-gallon battery-pressurized portable shower. Pour in water, hit the power button, and an onboard pump pushes a real 50 psi spray through a 7-foot hose — no hand pumping, no foot pumping, no hanging a gravity bag in a tree. That pressure is the whole point: it actually blasts caked mud and grit off gear, not just trickles over it.
The tank holds 4 gallons. That runs about 4.5 minutes on the full shower setting and up to 28 minutes on mist, so one fill covers a rinse-down or a quick camp shower with margin to spare. Pressure is strongest on the first few gallons and tapers toward the bottom of the tank — plan your wash order accordingly. The 5-setting nozzle steps from a tight jet for stuck-on muck to a soft shower spray for skin.
The 12V 5Ah AGM battery holds its charge for months between trips, so it's ready when you grab it. Recharge it off the included AC wall charger, the 12V vehicle cord, or USB-C, and use the onboard USB output to top off a phone or headlamp. The IP65 control panel reads out water temperature and battery level. The body is UV-protected HDPE with stainless tie-down points so it rides without rattling loose. It weighs about 15 lb empty, roughly 47 lb full.

Use cases
Built for cleanup away from plumbing. Overlanders and truck-campers run it as a bed-mounted water source, charging it off the vehicle between stops. Mountain bikers and dirt-bike riders use the 50 psi jet to strip trail mud off frames and themselves. It doubles as a dog-rinse, a dish station, and a kayak/cooler wash — anywhere a pressurized stream beats a gravity bag.

Does the Cube heat water, or is it cold only?
There is no built-in heater. The control panel shows the current water temperature, so you know what you're getting. For a warm rinse, fill it with warm water before you head out, or add the HyperHeater 2.0 accessory (sold separately), which heats water to about 120°F.
How long does a full tank spray for?
Four gallons runs roughly 4.5 minutes on the full shower setting and up to about 28 minutes on the mist setting. The first few gallons spray strongest; pressure tapers as the tank empties, so the last gallon is more of a stream than a full spray.
Can I charge it in my vehicle while driving?
Yes. The Cube ships with both an AC wall charger and a 12V vehicle charger, so you can top it off on the road. The AGM battery holds its charge for months between uses, so it's ready when you grab it.
How heavy is it, and how do I keep it from sliding around?
It weighs about 15 lb empty and roughly 47 lb full. The body has stainless steel tie-down points so you can strap it down in a truck bed or cargo area and keep it from shifting on rough roads.
Can I leave it outside in winter?
Keep it above freezing while there's water in it — freezing can damage the internal pump. Before cold storage, drain the tank and run the pump dry for about 30 seconds to clear any remaining water from the system.
