Everything I've tested.

A jet lighter that feels far more powerful and burns straight through the board quickly.

Filtered very dirty, muddy and algae-filled water into drinkable water, tasting poor but keeping him safe, and could change many lives.

Impressive and it works, but the use case is too niche for him to keep it.

Claims 30 watts, but in the test it could not get a dead iPhone to boot and he would not keep it.

Pedalling for 30 minutes failed to get a dead iPhone to boot, so he wouldn't keep it.

An interesting hybrid, but less convenient than a cheap lighter and awkward for starting a real fire.

Genuinely keep feet dry and protected; pricey but a standout he called a lifesaver.

A rechargeable plasma lighter with built-in fire-starting putty that he found the best lighter and kept over the matches.

Shown briefly while buying, with a quip about just using the tap.

A tiny multi-tool pump that does many things but is not powerful enough to inflate the tent, so he passed on it.

A watch with a built-in fishing reel that he mocked but did not test.

A simple, smooth thermal camera that easily found a hidden person in dark woods and was insanely fun to use.

Cheap zip-tie stitches that close small wounds without skill and were kept for minor cuts.

A striking, sturdy inflatable tent that survived the night and would make the cut for an extreme trip.

Absurdly bright and overkill for nearly everyone, but it does what it claims and he wanted to keep it.

A powerful, clean magic-wand fire starter that he liked, but it needs mains power and suits a home barbecue rather than an expedition.

Matches that stay lit when wet and are great for the price, though they were dropped in favour of the Pyro Putty lighter.

A better-thought-out portable satellite dish than expected, giving fast enough internet for HD Netflix in the middle of nowhere.

Removes about 98% of the mud from pond water; not perfectly clear, but he'd keep it as a potential lifesaver.

The traditional lighter done right and the most reliable flame, but not nearly as good value as the plasma arc lighter.

Joked about for its huge number of tools but not tested.

A smart, nearly smokeless fire pit with a built-in fan and power bank that he loved and would take with him despite its bulk.

Generated so little power it couldn't even boot a dead iPhone, so he wouldn't rely on it.

Compact and clever, but too much of a gamble on sunlight and the food came out chewy, so it didn't make the inventory.
