JSD12-6L 12kW Portable Gas Water Heater: High-Capacity Off-Grid Series

Description

Key Features

• Massive 12kW / 6L/Min Thermal Output

  • What it is: A high-capacity gas burner and heat exchanger system capable of delivering 6 liters of heated water every minute.

  • Why it matters: Standard 3L/min camp showers are sufficient for basic rinsing, but washing thick mud, heavy grease, or long hair requires true residential-level water volume and heat penetration.

  • Customer benefit: Delivers an uncompromising, high-pressure shower experience that matches home plumbing, perfect for extended luxury expeditions.

• Autonomous 90-Minute Lithium Battery

  • What it is: A built-in 4500mAh rechargeable lithium power bank that drives the internal water pump and digital ignition system.

  • Why it matters: Eliminates the need to tether the unit to a running vehicle engine or haul bulky external 12V leisure batteries to the shower tent.

  • Customer benefit: Provides up to 1.5 hours of continuous hot water operation per charge, easily supporting a family of 4-6 people over a weekend camping trip without needing a recharge.

• Versatile Propane & Butane Compatibility

  • What it is: A flexible combustion architecture engineered to handle a 5000Pa gas supply pressure from both butane and propane sources.

  • Why it matters: Gas availability varies heavily by region and altitude. This unit guarantees functionality whether connected to standard BBQ propane tanks or high-performance overland butane canisters.

  • Customer benefit: Ensures global usability and reliable ignition for end-users, regardless of their geographic location or local fuel market.

• 65°C Maximum Temperature Safety Threshold

  • What it is: An intelligent heating core that safely pushes water temperatures up to 65°C (149°F).

  • Why it matters: While 40°C is perfect for showering, higher temperatures are absolutely critical for sanitary dishwashing and field equipment sterilization.

  • Customer benefit: Transforms the heater from a simple camp shower into a versatile field utility tool for cooking hygiene and heavy-duty gear cleaning.

• Rapid 12V DC Vehicle Charging

  • What it is: The system includes a DC 12V power adapter designed to recharge the 4500mAh battery from 0% to 100% in approximately 3 hours.

  • Why it matters: Overlanders move locations frequently; the ability to rapidly recharge the unit from a standard cigarette lighter plug during transit is vital.

  • Customer benefit: Keeps the off-grid water system fully operational indefinitely, leveraging the vehicle’s alternator during daily trail driving.

Application Scenarios

Heavy-Duty Overlanding & RV Retrofits

Vehicle builders outfitting expedition trucks and RVs require appliances that deliver maximum performance in a minimal footprint. At just 340x145x280mm, the JSD12-6L slides easily into custom slide-out kitchen drawers. When deployed beneath high-coverage vehicle awnings, the 6L/min flow rate provides a flawless dishwashing and showering station, making it the perfect upsell for customers purchasing large hard shell roof top tents for long-term off-grid living.

Mobile Pet Grooming & Equine Care

The 12kW heating capacity and high volume output make this an incredible B2B crossover product for the commercial animal care industry. Mobile pet groomers, dog show competitors, and equestrian riders use this portable platform to safely and comfortably wash large animals in remote fields or parking lots without relying on cold hoses.

Disaster Relief & Field Basecamps

In emergency situations where municipal water grids are compromised, NGOs and field worker crews need reliable sanitation immediately. The 90-minute internal battery and extreme 65°C temperature threshold allow disaster relief teams to pump hot water directly from river bladders or jerry cans to sterilize cooking equipment and maintain strict hygiene protocols for dozens of workers.

Why Choose This Product

• High-Margin Premium Retail Tier: By doubling the flow output of standard 3L/min models, distributors can position this 6L/min unit as a premium “pro” upgrade, significantly increasing cart value.

• Exceptional Power-to-Weight Ratio: Despite outputting a massive 12kW of heat, the entire chassis weighs only 7.25 kg, maintaining strict portability for space-conscious 4×4 owners.

• Completely Tether-Free: The internal 4500mAh battery completely separates the water heater from the vehicle’s starting battery, eliminating the risk of draining the car’s power grid while showering.

• Optimized B2B Logistics: The secure 512x460x225mm master carton sizing is engineered to stack perfectly on standard shipping pallets, drastically reducing maritime freight damages and lowering your landed cost per unit.

• Brand Identity & UI: Precision laser-etched logos on the metal chassis, custom dial colors, and bespoke warning/instructional decals.

• Chassis Finishes: Upgrade from standard paint to high-durability tactical powder coatings (such as Olive Drab, Gunmetal Grey, or Desert Tan) to match your existing overlanding catalog.

• Private Label Packaging: Tailored master cartons with custom SKU barcoding, shipping marks, and full-color retail graphics designed for immediate shelf display.

Frequently Asked Questions

What is the main difference between a 6kW (3L/min) and this 12kW (6L/min) model?

The 12kW model delivers twice the heating power and twice the water volume per minute. While a 3L/min model is excellent for basic camping showers and saving water, the 6L/min model provides a high-pressure, residential-style flow. It is heavily preferred by users who have long hair, families needing faster back-to-back showers, or commercial crews washing heavy equipment.

Can the 4500mAh battery be replaced or serviced over time?

Yes. Designed with long-term asset longevity in mind, the internal lithium battery pack is accessible via a secured service panel. B2B distributors can easily stock replacement battery modules to provide localized after-sales support to their retail customers over the years.

What is the maximum water temperature, and is there a safety shutoff?

The unit is capable of reaching a maximum temperature of 65°C (149°F), which is ideal for sanitizing dishes or gear. For user safety, the system is equipped with an integrated thermal cut-off switch that instantly kills the gas burner if the internal sensors detect temperatures exceeding the safe operational threshold, preventing severe scalding.

Do I need to keep the vehicle running to charge the water heater?

No. The unit’s internal 4500mAh battery allows it to run completely independently for 90 minutes. When it is time to recharge, you can plug the included 12V adapter into your vehicle’s cigarette lighter socket while driving to your next campsite. It reaches a 100% full charge in just 3 hours.
