New startup Q Designs seeks to help solve a problem that many people have: we sometimes need to power our mobile electronic devices, but we don’t want to carry external battery packs or bulky charging cases. Q Designs’ solution, the QBracelet, looks like an ordinary bracelet, but it is actually a high-tech charger that can juice up your electronic device discreetly.

The QBracelet will work with iOS and Android devices at launch. No cord is needed, since inside the bracelet’s clasp there is a lightning adapter for Apple products and a micro-USB port for Android devices.

The QBracelet has a built-in rechargeable lithium-ion battery that will recharge most smart phones up to about 60%. Depending on the battery level of the phone it can take up to 60 minutes to fully recharge your device. The battery has a standby life of 30 days. Recharging the bracelet takes about 90 minutes with LEDs located above the connector to indicate the current charge level.

The bracelet’s exterior is made out of high-grade aluminum with an interior of polycarbonate plastic. This makes the bracelet very lightweight and durable. The bracelet is designed for men and women and comes in several finishes: brushed and matte black, polished and matte silver, and polished gold. It comes in three sizes small, medium and large.

Today the QBracelet is available for pre-order for $79. It will retail for $99 once it launches. Pre-orders will ship in time for the winter holidays.
