8KW Diesel Heater, 6L Portable Diesel Air Heater All in One 110V/12/24V with App Control, Wireless Temperature Sensing and Altitude Mode for RV Garage Camper 2025 Toolbox 2s

I purchased the HCALORY Toolbox 2 Diesel Heater earlier this year, and I’m extremely impressed with its performance and portability. The compact design makes it easy to move and set up wherever needed, and it’s well-built for outdoor and camper use. I tested it during a trip where nighttime temperatures dropped to -5 degrees, and it kept my camper warm and comfortable all night without any issues. The heating output is consistent and efficient, making it perfect for cold-weather adventures. I made a small modification by extending the wiring for the control panel so I could mount it inside my camper. This allowed me to use the thermostat and temperature control mode conveniently from indoors, which worked flawlessly. Overall, this heater delivers excellent value for its price. Reliable, powerful, and portable—highly recommended for anyone needing dependable heat in harsh conditions.

At first I was worried after reading all the reviews on diesel heaters and hearing the horror stories some people have had. The unit came well packaged, all parts were as advertised. After unpacking I inspected the unit and it looks sound and well built. Like most, the directions are not the best, but if you take your time you can figure it out. The few things you have to put together are easy to figure out via the pictures. The directions on the App are easier and better to understand. I set it up, primed it and turned it on. System came up first time. The fan and pump do make noise but it's nothing annoying. Love the heat it pumps out. I'm using this in a 6'X12' box trailer camper conversion and it will keep it at 60 degrees on level 1 when it's in the low 20s at night. All three input options work, the front panel, keychain and app. I am extremely happy with this purchase. ***Update*** Have been using the heater all winter without any problems, I've never let it run out of file and it always comes on when needed. The timers are nice but the thermostat function is +- 6 so that is a huge swing and useless to me. I have five timers set for the night, it will come on to the level it was last on, I have it on two and run it for 30 minutes. Warms up the camper and with them spread out I'm never cold. This heater has gone above and beyond even with the few issues it has. Will buy another if ever needed.

Still workin Like a champ. I have been using this heater when I’m in my tent in cold weather. Truly a game changer, once it’s warmed up and running for a bit, the only thing u hear is the heater not the fuel pump. I also use this in my shop to heat my work space when I’m doing projects or truck maintenance. This heater really cranks out the heat and is VERY efficient on diesel fuel. I have put together a small “pelican” case for the accessories the heater uses to run. I do wish there was a way to stow all those parts within the main body of the case. Still super happy with this purchase.

The product as shipped is very good, however I chose to upgrade and enhance the original design. I changed out some parts and introduced others, all for a more efficient, functional user experience. I replaced the fuel line with what I deem, a better one. I installed a water displacing fuel filter and a fuel line shut-off valve for safety. I replaced the poor quality hose clamps with stronger ones. I sealed the exhaust connection with a high temperature silicone sealant. Incorporated a high-temp silicone 3-1/2 to 4 inch elbow to guide hot air output. I routed a slot in the case cover, allowing me to monitor the fuel level inside the fuel tank without having to open the case. These were all performed with further safety in mind as well as improving this units usability. Once I accomplished all the above enhancements, I then fired up the unit for a successful first run. The unit performed well - as expected. It’s a good design overall, functional and transportable. With the ability to control this unit by way of onboard display as well as a (included) remote and simple (Bluetooth) software for your phone, monitoring and controlling this unit is super easy. The app is very simple, however it provides essential information like altitude, internal body temperature, ambient temperature and input voltage. It allows you to control fan speeds, thermostat and altitude settings. Some things to be aware of: • The fuel tank should be inspected for manufacturing debris. Mine needed to be removed, washed out and let to dry. There were chunks of various things left in there from manufacturing. • The unit begins its process slowly on start up. It heats the glow plug, then begins pumping the fuel. The fuel line is circuitous and it may take a couple “pumping sessions” to finally get fuel to the combustion chamber. • The unit requires the most electricity at this start-up phase (at least 120 watts). While running at full speed, the unit used only 35 watts to maintain heat. • The pump clicks consecutively and somewhat loudly. It quiets down while running at full speed and becomes hardly noticeable. The overall noise level of this device is fairly loud (air flow mostly). • As mentioned, the opening where the hot air comes out is 3-1/2 inches in diameter. The manufacturer provides an expandable tube that fits this port, however it is rather short. • The plastic case, although similar to a Pelican brand case, is not of that quality. The walls of the case are structurally reinforced, but the density of the plastic is nowhere near that of a Pelican brand case.
