The Lone Rock Concepts Military Can Overland Water Pump Adapter Kit converts any U.S. military-issue plastic water can (20L / 5-gallon) into an on-demand pressurized faucet. The kit centers on a USB-C rechargeable electric pump and a patented CNC-machined UHMWPE adapter (US Patent No. 12,474,000) that threads directly onto the military can opening — no drilling, no permanent modification. Rated for 30 gallons or 30 days per charge, whichever comes first. A 30-second auto-shutoff prevents accidental pump runoff and battery drain.
At camp the pump delivers consistent pressure regardless of how full the can is or whether it's on a shelf or in the truck bed. That's the practical difference from tipping a full 20-liter can: gravity-fed flow drops as the container empties; the pump doesn't. The 304 stainless steel spout is reversible for a drinking fountain orientation. USB-C charging means any power bank, vehicle outlet, or solar panel with a USB-C port keeps the pump charged — no wall outlet required.
Fits U.S. military-issue plastic water cans (20L / 5-gallon) marked "PROPERTY OF U.S. GOVERNMENT" — the rectangular HDPE cans in tan, green, and desert variants. Does not fit Scepter jugs (different thread pitch — use the Lone Rock Scepter Kit) or Wavian / metal NATO cans (different bung standard — use the Lone Rock Wavian Kit). No filtration — use pre-filtered water. Military can not included. Kit includes: electric pump, CNC adapter, USB-C charging cable, food-grade silicone hose, 304 stainless steel spout, storage pouch.
