CAMPLUX Nano 3 Pro 1 lb Propane Portable Water Heater, Table Top Camp Water Heater & Shower Pump w/Built-in Battery, Compact Outdoor Camping Hot Showers

UPDATED REVIEW: This is an update to my earlier comments regarding the Camplux Nano 3 water heater. To make a long story short, the fine folks at Camplux reached out to me regarding my review. After multiple emails, we came to the conclusion that one of their other units would be better suited to my needs. They provided me with a BW158 water heater at no cost. The BW158 has more than met my needs and has exceeded my expectations. I find it to be a durable, well built unit that is superior to its competitors in build quality and performance. I’ve been using it for about two months now. Once the temperature is dialed in, it remains steady/constant. There have been a few breezy days when I have used it and the flame stays lit, providing me with more than enough hot water for my shower. One thing I have noticed - the digital readout is not very bright and I have to cup it with my hand in order to read it. However, that’s a minor detail. I consider my set-up to be semi permanent which is why the BW158 fits my needs to a “T”. The Nano 3 is more for off grid or remote use where there is no access to a dedicated water line. I really appreciate that Camplux contacted me and we were able to get a better understanding of which unit would work best for me. If you’re considering a BW158, buy with confidence. Their superior customer service and quality product has won me over. Original review I did a lot of research into this unit before purchasing. Imagine my disappointment when it came and there was no way to charge except via a car. If I wanted to charge from my house, I would have had to spend more money for a different adapter. Supposedly it can be hooked up to a hose, but it seems as if the design favors getting water from a creek, river, lake, etc. Again, more $ for an adapter. No thanks.

Works great, happy with the performance after having had it a month. I do have a complaint. The only charger that’s provided is the cigarette plug style. The manual says don’t use a AC to DC adapter. I don’t understand why they engineered it in a way that would eliminate the possibility of AC charging. So your left with having to use your car, generator or power station. Not a problem for a lot of people but it also is a problem for a lot of people. Would be nice to be able to charge it in your house. Very disappointed with the shallow thinking of that design. Update 5/13/26 After 3-4 months of use the unit now runs for a few seconds, overheats & shuts off. Maybe my well water caused the passages to be restricted idk, my water runs clear but there can still be mineral build up. My shower setup now consists of a 5 quart pale which I fill with 2.5 quarts of cold water & my GSI 1 quart stainless kettle which I use to boil 1 quart of water & mix with the other 2.5 quarts of cold water & dip it out with a cup. If I’m being honest I’m done spending money on all these gadgets. There’s nothing to fail on a kettle & bucket. That’s my recommendation.

There seems to be a quality issue with the Nano 3 Pro. I had to return mine 2 times because the units wouldn't charge right out of the box. Initially the display shows that it is charging but after a few minutes it shuts down and won't charge anymore and the charge display never got above one bar. Amazon customer service was great and they refunded the money and advised me to purchase a unit from a different manufacturer. I decided to go with a Fogatti portable gas hot water heater and I will review it when it comes, hopefully it will work.🙂

Solid tankless hot water heater. I did test it with water that was cool tot he touch and it didnt heat the water as good. Temp was just around 78 degrees out the spicket. Once I used warmer water (80 deg) it heated the water to 120 degrees. Not sure this is normal, but I now know not to use cool water.

We take this camping and it provides really nice hot showers! Love it a lot. It's very convenient that you can use the smaller propane tanks on it and I get about 8 showers out of a tank. This was a great buy and we've really enjoyed being able to take hot showers on demand. I am giving this 5 stars because the product really is great but I am going to list out some cons for people to be aware of. The cons: The power button is on the bottom, so to turn the unit on and off you have to pick up the end. Really odd place to put it. The manual is beyond terrible. The only charger that comes with the unit is for a cigarette lighter. Not only do not all cars have cigarette lighters anymore but you have to drive around forever to get it charged. You can purchase a plug to charge the unit but the manual doesn't tell you what you have to buy. You have to call customer service to get the information you need. Overall, once you get this set up it's very easy to use and gives a great shower. Lightweight and you can take a really nice long shower with just 3-5gallons of water.

I really wanted to love this. It was exactly what I was looking for but the first unit would overheat with the temp knob all the way on low. We returned that unit and got a slightly better one. It was still super finicky about the temp. We knocked it over and broke it after one trip and I gave up on it because it was past the return window. After my initial review Camplux reached out to discuss the issues and they have reworked the temp control on the next round of units. Even though we were past the return window they shipped us a replacement product and we are back in business. Honestly, may be the best customer service experience we have had. They really did offer to do anything and everything they could to make it right, and they listened to our feedback on the issues we had. Definitely have brand loyalty from us now.

UPDATE: The first one I received did not work at all. It had a faulty igniter. I contacted the seller via Amazon, and they immediately shipped a replacement. I have since used the replacement three separate times, and it works great!!! As long as that continues, I will be very happy, as I love the way this system works and packs down. So far their customer service to fix their problems has been great. I changed my review to 4 stars based on these factors. ORIGINAL: I purchased this before an off-grid camping trip. The directions are good and simple, but, just like other reviews, it did not work. I got the error code E3 and could not get the heater to ignite the propane. I am currently in the process of sending it back and getting a replacement. I will update you once I get it. Unfortunately, I did not have a hot water solution for my trip. They should fix their product to work every time.

i purchased the Nano 3 in April, charged the batter and tested and stored item for less that 90 days. the battery no longer had a charge and the battery will no longer charge. Good idea bad execution, trying to reach out to vendor for support. A $300 item should work as advertised.

Worked well for about 2 trips but then stopped igniting. I tried different regulators and attachments relating to propane but same this, it’s something internal. Won’t allow propane to ignite. Pretty upsetting…. *update, they sent me a replacement after a quick troubleshoot. I am happy with this product*

This was a complete waste of time and money to order worked for 5mins then stopped pumping water pump runs but cannot pump water through unit. Don't recommend buying this unit.

This unit is a game changer for us - no more bathing in a cold lake. We love this hot shower unit. We communicated with the Camplux support team a few times regarding operating the unit and an issue with the regulator, and found the team extremely attentive and helpful. We are very satisfied with our hot shower unit and recommend Camplux without hesitation.

Purchased the Nano 3 Pro and it functions fine but the temperature of the water is not very hot. On the max temperature setting it’s still very cool. If you test the water temp directly as it exits the shower head it’s warmish but to have a shower with the head further than a foot or two away from you the water feels mild to cool. Otherwise it’s an ok unit. Wish it was warmer. Possible solution that I have found. If the water is cool to start with then I’m simply running the heated water from the unit back into the bucket which brings it up to a better starting temperature. Essentially heating the source water a little.
