Poor design
3 months ago
I bought this but it’s not well designed. The base of the burner is a polycarbonate plastic. The burner ONLY fits the jetboil pot and you cannot use it to heat anything else - so no cooking pasta or rice or anything else in another pot. You need to take a second burner into the mountains to do this. There is no air vent in the design to allow heat to release if you use anything other than the jetboil pot. The plastic base of the burner melted and now it does not slide into the pot. It’s rather stupid to have a system that can only be used for one purpose - boiling water. It should be multipurpose if you carrying all your own kit on your back deep into the wild. I should not have to pack a second burner. I feel it would be easy to adapt the design to allow this and I would not make a burner from polycarb. It should all be a lightweight metal alloy

Thank you for your review. We are sorry to hear of your experience with the "Flash" model! Any of the Jetboil "Precision Cooking" series (MiniMO, MicroMo, MightyMo or SUMO) are the way to go if you need a more versatile stove capable of simmering. These models also include a Pot Support for elevating flat bottom pans safely above the burner to prevent any melting of the plastic burner shroud. Original Jetboil designs or their descendants such as the "Flash" are intended specifically for boiling water for hot drinks or reconstituting freeze-dried or dehydrated trail foods. For boiling water in a flat bottom vessel (non-original to the system), the Pot Support is offered separately. Polycarbonate material is very lightweight and has been used since the original Jetboil PCS & GCS models were introduced in 2003. The polycarb offers a means to adjust a lit unit without contacting hot metal parts. Properly used, a burner will last decades without any melt issues. For support with your particular unit, please contact Customer Service at 1-800-572-8822 M-F between 8am and 4:30pm EST

[This review was collected as part of a promotion.] As an old school camper I’ve always used a percolator to make my coffee. It wasn’t the best but it did the job. Wanting to step my game I found the Jetboil Java kit. After researching it for a while I decided to pull the trigger. What a game changer. This is my first Jetboil product and I’m very pleased with it. Within a couple minutes I have a hot cup of coffee with no grounds floating around. It packs away nice and neat so it takes up minimal space. Definitely worth it.
Yes , I recommend this product

DO YOU need offgrid coffee available in 5 minutes or less? This is your product. The water boils in less than 2 minutes, then the French press steeps for 3 minutes, press the plunger down and you have 2 delicious cups of coffee. This packs sooo small and light! Even if we weren't offgrid I'd still use this as my camping coffee solution. I am a little confused how the conventional jetboil cooking attachments work with this setup but I'm sure it's easy enough to figure out. VERY happy with this purchase.

boils a liter in about 3 mins It is the best method to boil water quickly if you are just making a meal or making coffee. I use it for my backpacking adventures and even camping with the family. the new model is great because the flame dial (or whatever its called) it a great improvement over the previous generation. Will continue to use the product for years to come.

Extremely easy to use, very stable with the included base, and boils water for my coffee in no time flat. The included press makes brewing my coffee a snap and I can get away from the coffee singles that make flavorless brown water.

Ease of use and speed while on a week long motor camping trip. No issues even in the rain. Igniter lit it every time and the coffee press was a great addition. Glad I made the choice I did in purchasing this!

Great product. Although a slight bit heavier then my other set up, the super fast boil time makes it well worth it.
