The Olight imini 2 is a keychain-sized flashlight now selling for $11.99 at Amazon, a 40% discount from its usual $19.99 price. The source notes that is just $2 above the product's all-time low. At 2.17 x 0.59 inches and 0.69 ounces, it is roughly the size of a USB flash drive and designed to live on a keychain.
For PC builders, the appeal is the magnetic base, which lets the light stick to a metal case, car hood, or fuse box for hands-free illumination. The flashlight has no physical button; detaching it from its magnetic cap turns it on. It outputs 50 lumens with an 80-degree beam, which the article describes as more of a floodlight than a focused flashlight.
The imini 2 is powered by an 80mAh 10180 lithium battery and charges through a built-in USB-A plug, eliminating the need for a separate cable. The source claims up to 60 hours of continuous use per charge and rates the USB plug for 10,000 insertion cycles. The aluminum body is rated for drops up to five feet and carries an IPX6 water-resistance rating. This is a deal write-up rather than a hands-on review, so those endurance figures come from the product's stated specs rather than independent testing.
