Review

Ever since I got my hands on the Infinity X1, it’s been a game‑changer. Holding this 12‑inch, aircraft‑grade aluminum beast is like wielding a serious tool. It survived a few accidental drops (1 m tested) and kept working, which is a testament to that rugged build.

Twisting the head gives that satisfying adjustable beam, from a tight 180 m (590 ft) throw to a wide, room-filling flood. The beam is smooth, no harsh hotspots, which is great for everything from hiking long-distance trails to lighting up close quarters.

Power-wise, it flexes between using the included 4,000 mAh USB‑C rechargeable cartridge and a 9-AA dry-cell backup. On rechargeable, you get up to 5 hours on medium, and about 2 hours on high. Switching to alkaline yields about 1,200 lumens and cuts beam distance roughly in half, but keeps you lit in a pinch.

There's a USB‑C IN port that can take a few hours to get a full charge, or use the flashlight as a powerbank through the USB‑C out port. Never thought I’d rely on a flashlight to power my phone, but here we are.

The button cycling through High → Medium → Low is intuitive. There’s also a heat-lock safety that cuts power when overheating, and a tail-cap power-lock prevents accidental turn-ons during storage.

One Consideration

Now, just to be fair the beam throw is super solid but not class-leading. Yes, the X1 reaches about 180 meters, but I’ve seen other flashlights in this price or weight class throw well past 200+ meters. If long-distance spotting is your top priority, that’s worth noting.

But here’s the thing: that doesn’t take away from what makes this light excellent. The construction is tank-solid, the light quality is beautifully even, and battery life (especially on medium) is impressive.

For real-world scenarios, like changing a tire at night, dealing with a rogue blackout, or just night hikes and camping, this flashlight keeps you lit, steady, and covered for hours. And that’s exactly what I need.

Conclusion

For a flashlight from Costco, the Infinity X1 proves its worth. It’s a solid, feature-packed powerhouse: insane brightness, flexible dual power, handy USB‑C, and rugged design. Whether you’re trailblazing, prepping for power failures, or just need a reliable backup, this light is worth every ounce of heft.

In summary: I love it, plain and simple.
