No leaks even when moving it!!!

The biggest dislike I have had for other portable diesel heaters is that they leak like a sieve when moving them. I was concerned about moving this one since it fills laying flat then the wheels make it travel standing upright, but there was no leaking whatsoever!!! It did a great job of warming up my extra large cabin tent even in 20 degree F weather!!! It starts up quick, the phone app is intuitive and easy, and it runs well off either a 12v battery or with the included 110v adapter.

I'm seriously impressed!

I have been looking for something like this for two reasons: heat my garage while I work on my hobbies and as a backup way to heat the house during power outage or furnace failure.
This thing REALLY puts out a massive amount of heat and an impressive volume of hot air- I had NO idea something so small could do this. I will install an exhaust port in the wall of the garage and have no doubt this will bring it up to a reasonable temperature. In the even of a power outage I can easily run this from my solar power system and batteries since it runs on 12V. I may even get another one to use for preheating my airplane engine.
As of yet, I have not installed the app but will give that a shot. The included AC adapter was how I initially powered this for testing, but there's also an AC port on the side which isn't mentioned in the instructions- so not sure why they included the AC/DC adapter if it can take a direct AC plug... but no mention of it at all.
The only caveats- it has no ducting or anything, so if you need to direct the air into a vehicle or RV etc you will need some 3" ductwork. Also, the exhaust tube gets blazing hot- I measured it at 369 degrees Fahrenheit. If you happen to even brush against it, it WILL burn you or melt anything it touches. Be careful with something that hot. When you shut down, it runs the fan and quickly cools itself down. The fuel tube inside is longer than it needs to be, and it seemed to cause a delay in getting up and running as fuel had to travel through a long loop. I'm going to make a direct short run for it.
In summary- I'm super impressed with this! I had no idea something so small could put out that much heat! HIGHLY recommend this heater!

5L tank diesel heater.

Husband says it performs just as well as the diesel heaters in the cabs of his equipment at work.
You can operate this with the manual screen, remote, or via Bluetooth app. The app does not collect any data if that is something that may concern you. The instructions are well written and not broken English. Comes with a 120v AC to 12v DC power supply and 2 of flexible stainless exhaust tubing with a muffler.
I like how the case easy comes apart for inspection and to clean up any possible spills. The case is well thought out and has metal around the exhaust port. Has an inline fuse for the positive side. Outlet is 3 OD if you want to get a tube to direct the heat.
Only downfall is when the tank is full the bracket sags and allows the cap of the fuel tank to rest on the case opening. Not worth a star reduction but is worth mentioning since it can be difficult to get the cap back on after filling up.
The case really makes this a portable heater.

Highly impressed!
