TL;DR: Enjoy pocket-ready illumination with this keychain flashlight that delivers up to 1,000 lumens of light. Grab it on sale for $14.99 for a limited time.

The flashlight built into your smartphone is undoubtedly useful — but only to a certain extent. Whip it out when you need to locate your seat in a dimly-lit cinema or when you’re attempting to find the other pair of earrings you dropped in your living room. But for things like overnight camping, emergency repairs on the side of the road, or rifling through your stuff in the basement, you would need more illumination than what your phone provides. In that case, you’d need something like the COB Mini Keychain Multi-Function Flashlight, now on sale for $14.99 (reg. $21) as part of our Back-to-School event.

Don’t knock it ’til you try it. This portable flashlight may be tiny, but it doesn’t play when it comes to lighting. Thanks to its powerful LEDs, it can deliver up to 1,000 lumens of brightness, making it ideal for use on your outdoor adventures. It’s also powered by COB technology (chip-on-board LED), which means it’s a reliable source of light, shining a wider and brighter beam, all while consuming less power.

With seven different light modes, which include strobe and SOS, you can easily control the brightness depending on what the situation demands. It also doesn’t require any battery, as it’s designed to charge via USB.

Instead of frantically searching for triple-A batteries when it runs out of power, all you need to do is connect it to your existing power bank just as you do to your smartphone. The best part? It’s as portable as they come. You can attach it to your keys or backpack zipper to have constant access to it. It’s also waterproof, has built-in screwdrivers, and can endure just about any weather or terrain.

During our Back-to-School sale, you can get the COB Mini Keychain Multi-Function Flashlight for only $14.99 (reg. $21) for a limited time. Check out this deal and others included in the Back-to-School Collection, ending August 13 at 11:59 p.m. PT.
