CAMPLUX Nano 3 Portable Gas Water Heater with Pump

The CAMPLUX Nano 3 is a portable gas water heater with an integrated pump, listed at 3 LPM for camping and other outdoor hot-water tasks. The listing describes battery-powered ignition and a pump that needs a separate 12V supply, so plan for both the required D batteries and pump power source.

Pros and cons

Pros

A pump kit, water hoses and shower head are listed as included, reducing the need to assemble those items separately.
Battery ignition is described for use without mains electricity, while the pump has separate 12V powering options.
A 3 LPM listed capacity and portable mounting designation suit modest outdoor hot-water tasks such as a shower, washing pets or cleaning.

Cons

At 3 LPM, the listed flow is aimed at modest-use outdoor tasks rather than high-volume hot-water demand.
The pump needs a separate 12V power source, and ignition needs 2×D batteries, neither of which is included.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the dimensions appear as 17W x 36.8H centimetres in the specifications but 17×40×36.8 cm in the feature text. The title and main details describe a gas heater, while the details also list Battery Powered, 3 Volts (DC) and 6 KW without clarifying how these power claims relate to gas heating and battery ignition. Check the selected listing for the applicable dimensions and power configuration. The feature text says a gas canister, 2×D batteries and a 12V pump power source are required and not included.

Who is it for?

A good fit for

Campers and vanlife users wanting a portable, low-flow hot-water setup with a pump kit.
Outdoor users washing pets, dishes or equipment who can provide a compatible gas canister and separate power for ignition and pumping.

Less suited to

Buyers needing high-flow hot water or a setup that works without arranging fuel, D batteries and a 12V pump power source.

Aggregate ratings are mostly five-star, with some four-star ratings and a small two-star share. That indicates generally favourable ratings in this limited sample, but the figures do not explain what customers liked or disliked, so they cannot establish how well the pump, heating or setup performs in practice.
