A few years ago, I posted a review of my Esbit Pocket Stove, a small metal box that weighs 3 oz and burns a single Esbit hexamine tablet.
In culling 14 years of backpacking equipment, I came across my Esbit Titanium Folding Stove ($12.28 at Amazon), which weighs a mere 0.40 ounces (on a very accurate electronic scale); less than 1/2 ounce (11.3 grams). The esbit fuel tablet that powers it weighs 0.45. Together, they add up to a mere 0.85 of 1oz (24 grams)! Does it actually work? I thought I would do a 2013 re-test for you super ultra lighters who like their trail food hot.
I fired up the tiny Esbit, added one cup of water (enough for a single serving of oatmeal or a cup tea or coffee) and got a rolling boil in about 3 1/2 minutes. A neat feature: you can blow out the flame and save what’s left of the fuel tablet for another meal. This test left more than a half tablet.
For two cups of water (enough for your oatmeal AND tea or coffee), it took about 8 minutes and used about 3/4ths of one fuel tab. Note: these tests were done at sea level.
If you are rehydrating food with water for dinner, you can figure 3 tablets per day (2 for dinner and one for breakfast). That adds up to 9 tablets for a three-night trip. Tablet weight: 4.5 ounces (9 @ 0.45); stove weight: 0.4. Total for three days: 4.9 ounces. Add a couple of more tabs for backup (less than 1 oz). You can buy a box of 12 Esbit 1400 Degree Smokeless Solid Fuel Cubes for just $4.99.
Be light. Be safe. Be one with the pack.
