When it comes to outdoor adventures and backcountry camping, cleanliness can be a luxury. However, with the Coleman Hot Water on Demand H2Oasis Portable Water Heater, cleanliness is no longer a luxury but a convenience.
Introduction
Being a seasoned camper, I’ve tried everything from baby wipes to solar showers to keep clean on the go. But nothing has come close to the comfort and convenience of a hot shower. That’s where the Coleman H2Oasis comes in.
What is the Coleman H2Oasis Portable Water Heater?
Imagine a tankless water heater that you can take with you anywhere. That’s what the Coleman H2Oasis is. This Portable Water Heater is a propane-powered device that can deliver hot water up to 125°F on demand. It’s like having a mini water heater in your camping gear.
Understanding the Coleman Hot Water on Demand H2Oasis Portable Water Heater
The Coleman H2Oasis Portable Water Heater operates similarly to a tankless water heater you might have in your home. It uses propane to heat water rapidly, with the ability to reach a maximum temperature of 125°F.

Quick Disconnect Hoses
This portable water heater is simple to set up. All you need to do is connect the two 6ft silicon hoses, attach the pump to the 5-gallon water jug, connect a 16.4 oz propane tank, ignite it, and adjust the temperature to your liking. The built-in lithium-ion battery, which powers the electric pump, can be charged using the included 12V car charger.
The Coleman H2Oasis is perfect for a variety of outdoor uses including washing dishes, making hot drinks, and, of course, taking a hot shower after a long day of hiking or sitting around the campfire.
How does it work?
Operating the Coleman H2Oasis is pretty straightforward. Connect the two silicon hoses, attach the pump to the 5-gallon water jug, attach your propane tank, ignite, and adjust the temperature. It’s that simple! And did I mention it heats up the water really fast?

Steamy Hot Water
Battery Life
One thing to note is that the Coleman H2Oasis requires a charge to power the electric pump. It comes with a built-in lithium-ion battery that can be charged using the 12V car charger.
Experience with the Coleman H2Oasis Portable Water Heater
I’ve found the Coleman H2Oasis to be an excellent addition to my camping gear. Its straightforward operation (once you’ve read the instructions) and ability to provide hot water quickly have made my outdoor adventures much more comfortable.
In terms of portability, the Coleman H2Oasis is lightweight and easy to move around, making it ideal for camping trips. Despite its compact size, it’s quite rugged and can easily withstand the rigors of outdoor use.
One of the features I appreciate the most about the H2Oasis is its pressure. I was pleasantly surprised to discover that the pressure is quite strong, allowing me to rinse of food from camp dishes with ease.

Spray Distance
However, like any product, the Coleman H2Oasis is not without its drawbacks. It needs to be charged for a full 6 hours before the first use. It comes with a standard 12v male socket for charging, but a wall charger must be purchased separately.
Another downside is that the water cannot be shut off while in use. This means that you either have to turn the unit off and restart it or you could continuously cycle the showerhead back in the water if you happened to be using a bucket or tub of water to prevent wasting water.

Pump can also be submerged in a bucket or tub of water for use.
Despite these minor inconveniences, I believe that the Coleman H2Oasis is a worthwhile investment for anyone who enjoys camping and outdoor adventures. It’s almost perfect and offers a lot of convenience and comfort for a reasonable price.
