About Us

Chargerless was founded in 2025 to build the first all-day wearable for everybody.

Our first product, Ray, is a self-sustaining bracelet that does everything we expect from a fitness tracker without any of the hassle of charging. Oh, and it's the lightest and smallest fitness tracker out there.

We're putting the finishing touches now, and excited to get it on the wrists of users like you. We're anticipating shipping in Fall 2026 and you can preorder now on our store.

Why'd you make this?

Hi, my name is Andy, I'm the founder of Chargerless. I've been wearing a fitness tracker for most of my life, and I think they're the best way to track my health, sleep, and exercise goals. But recently, it's just started getting annoying: it's dead when I want to see it, I need to remember to plug it in every other night, and it's big and ugly on my wrist.

My background is in engineering, so I started making my own wearable to solve these problems. My ideal tracker is so tiny and lightweight that I wouldn't notice I was wearing it, and minimal enough to go with any outfit. Even then, I didn't want to give up any quality — my device would need world-class health sensors just like the other devices I was used to: heart rate, HRV, sleep, body temperature, and much more. But why hadn't anyone done this before?

Today's wearables are big, and I realized they all shared something that made them big: the battery. Because these wearables couldn't charge themselves, they needed to carry all their power with them like a big backpack. But if we could add a way for our wearable to collect power on its own, like a small solar panel, then we could shrink the battery and keep all the features we care about. This inspired me to start Chargerless.

When can I get one?

We've started the manufacturing process for the Ray, and estimate shipping in Fall 2026. If you'd like a device earlier, find some way to contact Andy and he may add you to the beta tester list!
