The media could not be loaded. I have been on the fence about buying one of these, for a while now. After researching several different brands, I decided to purchase the Wintemp model GPT3U. One feature I like, is the push button temperature control vs the dial style, as I think it's a more stable heat setting. I have only seen this control style on one other brand's updated model. The 4000 mAh internal battery makes it easy to place the unit anywhere you want. However, if it runs out of power, there's still the option to plug the car or wall charger into your vehicle or other power source. The GPT3U is super simple to set up. Just connect the regulator & propane cannister, hoses, put the pump into a water source and within 5 seconds, you have hot water! Some usage tips : I recommend keeping the blue cap that comes on the end of the shower hose (red) If you store the hose detached from the nozzle, you may lose the small white washer in the end of the hose. Screwing the blue cap back on keeps this from happening. Also, make sure you drain the water from the unit, after using. Detach both hoses and tip the unit forward, so that all of the water drains out of the ports. One other thing to note... if your water source is very cold, you may need to cycle the water through again to get your desired temperature , as the device will only be able to increase the temperature by 45° F. Lastly, the company has excellent customer service and communication, which is very important, as well as a great product!

Bought this unit in June 2025, when I first got it I plugged in the house charging unit and it worked as did the unit itself. I tried charging it the second time needing it for camping but the household charger isn’t working now. Tried going on their website and can’t find anything to contact them. Very disappointing you would think that they would have someway of contacting for parts. Definitely do not recommend this company. UPDATE since this review company has gotten ahold of me finally and I was able to get a new household charger just to along time for a response from them.

The media could not be loaded. I bought this for camping and for emergency situations where the power is out and my tankless water heater might not work. All, it's great, I bought an adapter to hook it directly into a large tank of propane. I used the water out of the bucket and he heated it up to about 117° which is warmer than most people would want. It only took about 5 seconds to get going so you shouldn't waste a lot of water. After the initial warm-up, the handle has a switch to turn the water on and off, which is great because you will need to work out of the bucket of this one. When you turn the water on and off the water will dip down to 90° or so and then take a couple seconds to get back up to where you originally had it. It's not shockingly cold but it's also not very warm. I don't really think this is a downside. I think it's a natural result of having it on demand camp water heater. I think the thing functions great. If there was one thing that I would change, it would be include a hose hookup for the water inlet. Since my plan is to use this in emergency situations, I could definitely see a time when I would want this hooked up directly to a main water supply. With that said, it's not really deal-breaker, it just means that everybody gets one 5 gallon bucket of water to take a shower and an emergency which is a lot better than the alternative. The actual box is very portable, reasonably lightweight, but there are a lot of accessories that you need to drag along. That you will need to run the unit anyways. It would have been great if it came with a collapsible bag/ portable water bucket so that everything could be contained into one single container. It's not a super cheap proposition, but I think the value is there if you want a warm shower when you're in the middle of nowhere, or a backup plan if you're in a place where the power goes out often.

It came out of the box flashing and EC error which means display malfunction. I'm still giving it 2 stars because I feel like it would be a good one looking at how well it was made. I'm sure this was something that happened with transporting it.
