Here's what to skip:

• Overpriced travel pour-over kits – Often just a dripper in a case. You can do the same with a rubber band and a mug.
• Electric kettles that can't boil – If you're outdoors, you need a stove or a 12V car kettle that actually reaches 205°F.
• Gadgets that promise perfect pours – Flow restrictors and fancy spouts won't fix bad grind.
• Buying gear before testing your current setup – Try a 1:16 ratio and a 30-second bloom first.

Also, don't overcomplicate your brew. In cold wind, your coffee will cool faster, so preheat your mug. That's free.

One-line takeaway: Avoid gadgets that solve problems you don't have.
