Your phone’s flashlight works fine until you’re elbow-deep in a car engine bay or fumbling with tent poles in the dark. Then you realize the limitation: you need both hands free, you need the light exactly where you’re working, and you need it to stay there without propping your $1,200 device against something greasy or precarious. The NanoB10 from Gadget On lives in that gap between “good enough” and “actually useful.”
This 3cm titanium flashlight attaches magnetically to your watch strap and rotates 360 degrees once mounted. Nine lighting modes cover everything from finding your keys to emergency signaling, while the dual-magnet system means it sticks to any metal surface at the angle you actually need. The whole package weighs about 24 grams and charges via USB-C. Sometimes the best tool isn’t the most powerful one in your house, it’s the one that’s already on your wrist when you need it.

24 grams puts this roughly in the same territory as a couple of quarters or precisely 2 AirTags, which means it disappears until you remember it’s there. Anything heavier starts pulling on your watch strap in ways that make you constantly aware something’s hanging off your wrist, which defeats the whole point of EDC gear that’s supposed to integrate into your daily carry without becoming a burden. The dimensions work out to 30mm x 27mm x 13mm, slightly larger than a nickel but thinner than you’d expect given what’s packed inside. Gadget On clearly spent time solving the density problem, cramming a 60mAh rechargeable battery, nine distinct LED modes, and two separate magnet systems into a volume that fits comfortably on a NATO strap without looking like you strapped a bottle cap to your wrist.
Two separate magnets handle different mounting scenarios, and the separation between them solves a problem most magnetic lights never address. One magnet lives in the body itself, letting you slap the flashlight directly onto any ferrous metal surface like a car hood, tool chest, or steel beam. The second magnet sits in the detachable clip, and this is where the 360-degree rotation becomes useful rather than just a spec sheet number. You dock the flashlight onto the clip magnetically, then spin it to whatever angle you need while the clip itself stays fixed to your watch strap, shirt pocket, or backpack strap. You’re no longer stuck with whatever angle the metal surface happens to be at, which is the usual limitation of magnetic work lights that just stick flat against whatever you attach them to.
Most keychain lights give you one brightness level and maybe a strobe if you’re lucky. The NanoB10 delivers four white LED modes at 1 lumen for night-light use, 35 lumens for low tasks, 100 lumens for medium work, and 200 lumens when you need actual throw. Add a white strobe for emergencies, two red LED modes at 2W and 3W for preserving night vision, a red SOS mode, and a 3W UV light at 365nm that’s actually useful for spotting fluid leaks or checking security features. Runtime on the 1-lumen night-light mode hits 15 hours, which becomes relevant when you’re trying to navigate a dark campsite without waking everyone up or need sustained low-level light for reading maps without killing the battery. The 200-lumen high mode obviously drains faster, but you’re using that in short bursts anyway.
Grade 5 titanium costs more than aluminum or plastic alternatives, but you can drop this thing, step on it, or leave it rattling around in a toolbox without worrying about cracked housings or stripped threads. IPX6 water resistance covers rain and splashes but stops short of submersion, which feels like the right tradeoff for something this compact. You’re not taking this diving, but you can use it in a downpour without killing it. The stonewashed titanium finish looks substantially better than the polished options in my opinion, though that’s entirely subjective. What’s objective is that titanium doesn’t corrode, doesn’t scratch as easily as aluminum, and develops a patina over time that actually improves the appearance rather than making it look beat up.
GADGET ON debuted the NanoB9 just last year, and managed to gather consumer feedback and knock out their next variant in just months. The base got redesigned for better magnetic hold and stability, machining tolerances tightened up across the body, and they added three more finish options based on user feedback from the previous version. That’s smart evolution because the core concept already worked, it just needed polish. The one-button control includes mode memory, so the light turns on to whatever setting you used last instead of forcing you to cycle through all nine modes every single time you need the flashlight. That small detail prevents the kind of annoying behavior that makes people abandon multi-mode lights entirely.
USB-C charging completes a full cycle in approximately 30 minutes, which aligns with the small 60mAh battery capacity. You’re trading extended runtime for size, but the math works when you consider that 15 hours on low gets you through most realistic use cases before you’re near a USB port again. The charging port sits under a small rubber cover to maintain the IPX6 rating, which adds one more thing to keep track of but beats the alternative of a corroded port that stops working after six months of exposure. The cover is tethered to the body, so at least you won’t lose it immediately.
The NanoB10 comes in five finish options: Wave (blue anodized with wave pattern), Matrix (green anodized), Stone (stonewashed bare titanium), Desert (gold anodized), and Slate (natural titanium). Pricing starts at £54 for the Stone or Slate single-color versions and £66 for the anodized color options, which translates to roughly $70-85 USD depending on current exchange rates. Shipping is estimated to begin in June 2026, with the flashlight and magnetic clip sold as separate items so you can add extra mounting options if needed.
