Bernzomatic JT850 Self-Igniting 20,000 BTU Outdoor Torch - High Output

In this review the Bernzomatic JT850 Self-Igniting 20,000 BTU Outdoor Torch is examined for gardeners, campers and homeowners who need a simple, high-output flame for outdoor tasks. The bottom line: it delivers a large, controllable flame with one-handed trigger start and a 36-in reach, making it best for weed control, firestarting and melting ice where a strong, instantly available flame is useful. The review focuses on real-world usability, flame control and fuel flexibility to help decide if this torch fits regular outdoor chore needs.

Key Features

• High output: Produces a large flame useful for burning weeds, starting barbecues and clearing moth nests in trees where more heat is needed.
• Adjustable flame control: The valve allows the user to size the flame for delicate tasks or full output and to extinguish the torch when finished.
• Trigger-start ignition: The integrated trigger-start mechanism provides quick ignition so the torch lights reliably without separate lighters.
• 36-in reach: The extended length helps access low or awkward spots with less bending or crouching, improving safety and comfort.
• Fuel versatility: Burns propane or MAPP Gas, giving flexibility depending on availability and desired heat output.
• Made in USA: Manufactured in the United States, which can be a quality and supply-chain consideration for some buyers.

Who It's For

The JT850 is ideal for homeowners and DIYers who need a powerful, handheld torch for outdoor chores like weed control, melting ice, starting firepits or barbecues, and small asphalt patch work. Its one-handed trigger start and flame control make it approachable for weekend use and lighter professional tasks.

It is less appropriate for precision indoor soldering, fine metalwork or industrial welding applications that require regulated welding torches and specialized tips. Users who need a torch for continuous heavy-duty professional welding should look at dedicated welding equipment instead.

Pros & Cons

Pros

• Large, consistent flame output that handles weed burning and firestarting effectively.
• Easy one-handed trigger-start ignition and a simple flame control valve for quick use.
• Long 36-in reach reduces bending and improves safety when treating low ground or clearing snow and ice.
• Compatible with common gases (propane or MAPP Gas) so fuel is easy to source.

Cons

• Not intended for precision indoor tasks or professional welding; flame is large and less suited to fine work.
• As a high-output torch it requires caution and safety gear during prolonged use to avoid accidental burns or property damage.
