    • Hot Showers again!
My water heater died and is costly to replace, tired of taking cold showers so I looked into portable water heaters, wanted on with small propane tank and rechargeable battery. Coleman unit fit the bill. I read the mixed reviews, watched the youtube videos and purchased. The only negative thing I can say it that it did not come with and ac adapter to charge/run at home. I was able to source one but I also found that the Coleman Powerchill ac adapter works as well, just a 120V to 12V cigarette type adapter for home. Used 4 times out of the box since I had no way to charge it without driving around for several hours. It will deliver scalding water so be careful. There is a trick to get it started just like a regular gas water heater, you have to hold the button down in the pilot position for a few seconds after it ignites to allow the element to get hot enough to keep the pilot from going out. I use a 14 gallon storage container for water, the 5 gallon jug that came with the unit was a bit light for my shower time. Shower hose is a little short but usable, Can't speak to longevity but I am happy to have hot water again. I do use indoors with exhaust fan on and a CO2 detector nearby, obviously despite warnings that is outdoor use only. Bottom line it works, wish I had one when I was a boy scout and camping ... show more

    • NEVER AGAIN
Either mine is defective or this product is the WORST hot water heater I've ever used. Its battery dies after about an hour of total use and though it offers a manual (electric free) lighting option, this is worthless if the pump cannot run due to a dead battery. It is not capable of being turned up to its hottest temperature otherwise it immediately shuts off. The only way to keep any continuous stream of LUKE WARM water is keep it turned so low that id have better luck using my body heat. Didn't get the opportunity to use it until the return date had expired so now im down several hundred dollars...... Wouldn't even give this one star. ... show more

    • Buy an extra battery
This was an amazing find for my camping supplies... Its designed to be very similar to the water heater you would find in your house... Fits easily into my camping gear... Works good but i would buy an extra battery if i was you cuz they dont last long if you have as many kids as i do... Water gets nice and hot... ... show more

    • A muat have prep
Easy to use and works great for emergency hot water or put it with a 55 gallon water drum, also was able to power it with battery pack since the heat is propane the electric draw is not very much so great for off grid, would have liked the pump to be a bit stronger and the water jug thing that comes with it is junk, but overall a great addition to any prep. ... show more

    • Test before going!
Was excited to have a hot shower while out moose hunting for 2 weeks, opened and assembled before we left, made sure pilot light came on but didn’t run water through it. Got in the field and it would not ignite the heating element! Pilot lite came on fine but unable to switch to heating. Also didn’t like that the only way to charge was a cigarette lighter. Went to Coleman’s website to buy the wall charger and apparently they don’t sell it, despite the manual saying they do. If it had worked, it claims one charge will heat 40 gallons which would be impressive. The water bag it comes with is flimsy and as water leaves the bag it will fall off whatever you have it set on to gravity feed into the “heater”. Finally used a chair with a restraint to keep it from falling, but never could get the heater to work. Looks like standard threads so could probably use a different “tank”. Should have actually ran water through it before leaving but with a trusted name like Coleman we figured if the pilot lit it would be good to go. They could improve the design by recessing the on/off switch. Ours got bumped in transit and was dead when we arrived. On the plus side, it’s lightweight, if it works it would be efficient with heating/pumping 40 gallons on one pump charge. Really wanted to like this product. Returning it. ... show more

    • Better than I thought
I have used this water heater for about three months now serval times a week and it is a good product, the 1 pound gas bottle will last for 10 or more showers depending on the amount of water used per shower the battery will last for a few showers don't know the real number because I usually charge it after every shower but the problem is you can't tell the state of charge of the battery so if you don't stay on top of chagrining every time you use it you can be $hit out of luck. Plus it does not seem to work while charging the battery. this should be fixed. Plus the instructions say the light will flash when charging but it only will flash four times and the goes steady even though it is still charging you don't know when its fully charged and how much of a charge it has so charge it every time or you will probably regret it. ... show more

    • A disappointment
I really wanted this to work. The design looks great. I loved the handle and carry case unit. Unfortunately mine was defective. When it arrived the box appeared to have been previously opened but all parts were there. When I used the unit at camp, the pilot did not light using the button that ticks and is supposed to light it. The on/off switch runs the water pump and if you shut it off to soap up, the propane flame goes out so the water is cold again. I had 3 cold water showers in mid October. I returned the unit. It is very disappointing because I wanted to pay extra for a convenient easy to use unit that works. It did not work or my unit did not work. ... show more
