So I picked up a Jetboil Zip the other day. I've avoided the integrated setups since they showed up because the weights just didn't make sense. With the recent versions, they're much more interesting. Will and Janet's incredible series put me over the top and I decided to give it a try. While I can still get a couple ounces lighter with my Gnat and Ti pot, at some point simplicity and compactness become worth a little weight.
Played around with it a bit and I'm sold enough to give it a shot. It is more efficient for sure. Most of my test runs get about a pint per 4-5 grams of fuel. My Gnat (and Snow Peak Giga) use about 7-8 in ideal conditions.
A few things weren't working for me, however. 1) I didn't like the knob flame control. It's hard to adjust with big fingers, almost impossible with gloves. I like the wire adjustment on the Sol series, but at literally DOUBLE the price, not worth it. 2) The neoprene cozy reeks. Like toxic nauseating reeks. I washed it. Put it through the dishwasher. Still reeks. Worst of all, everything it touches reeks. I was glad to see Will and Janet's note that it didn't significantly improve efficiency. Gone. 3) Not a fan of the lid. Very plasticky – I'd never drink my coffee out of it because of the smell and feel. It could be lighter, too.
So, with those shortcomings, I decided to tinker a bit. First up was the lid. The Snowpeak 700 and GSI Minimalist lids fit perfectly. They're heavier than the stock, however, so they're out. On a whim, I stuck a Ziploc lid on top. The groove lines up perfectly with the lip. Weighs a fraction of the original, too. It doesn't lock on, but I actually found the stock one too tight and it required too much force to pry off to check on the boil. Solution found.
Next up was the knob. My plan was to drill a couple tiny holes in it and add a wire knob. As I was looking at my Gnat's wire knob to see the correct diameter, it struck me that the burner shafts were very close in size. A couple twists later I had my Gnat valve on the Jeboil burner. The threads match, but a word of warning – they are not as deep, so don't tighten the burner too much or you'll strip the threads. There is a tiny gap left at the bottom. A washer could be put there to prevent overtightening, but it's not really necessary. In this setup, the plastic shroud still works. It, too, will need a washer to get snug. It's possible to leave it off entirely and save half an ounce, but the convenience of having something to grab to untwist the pot while hot is probably worth it. Fired it up and it was just as efficient as the stock setup. I'll admit I was afraid to really turn it up though. It's MUCH more powerful than the throttled stock stove.
Still playing with it, but here are the changes so far:
Stock Setup – Zip pot, cozy, lid, burner: 10.7 ounces
Stripped Setup – Zip pot, Ziploc lid, Gnat valve, no cozy: 7.9 ounces
With Shroud – 8.5 ounces
Why do it? I don't care about the cold weather speed of the Sol burners. We rarely get that cold in the Northwest and according to Will and Janet's test SPEED is impacted quite a bit, but EFFICIENCY is not. I can always spare an extra couple minutes in the woods for my water to boil. I care only about efficiency. The stripped weights of the Sol setups are 7.5 and 9.2 ounces without lids according to W & J's testing. With this setup (assuming you have a Gnat or something else that works), you get a setup just as light or even lighter for HALF THE COST. Another $75 to save a couple minutes of time in only certain conditions? Makes no sense to me.
I think the stock Zip is undoubtedly the best VALUE in the Jetboil lineup already. With these simple (and completely reversible) hacks, it's a steal.
My questions for the stove gurus out there: Any life-threatening consequences to this? I don't – and won't – cook in a closed space so I could care less about the CO issues. My main concern is that larger valve on the Gnat can crank out a lot more heat than the Jetboil stock one. Any potential issues with a blowtorch under that pot that I'm missing?
Still tinkering. Next up are the washers to get everything snug and possibly an igniter just see if it can be done.
