A life-saving pillow bracelet with which you can not be afraid to drown

A group of designers from the United States created an unusual bracelet, endowing it with the functions of a life buoy. In the event of an emergency, just a click of a button is enough to allow the gadget to stay on the water

American craftsmen launched a fundraiser for a new gadget that will ensure the safety of swimmers. The device is called KINGII and is, in fact, a lifeline that is worn on the arm and works on the principle of inflatable armrest pads for small children.

KINGII is now at the stage of the crowdfunding campaign. The company operates only a few days and during this time managed to collect already 30% of the required investment. Fundraising will last another month and a half, and there is reason to believe that the campaign will end with success.

KINGII looks like an ordinary bracelet. It is this feature that is fundamental in the mechanics of the device. At the touch of a button, a rescue pillow is inflated, which is able to keep afloat a person weighing up to 125 kg. This is quite enough to save not only the child, but also a sufficiently strong man.

KINGII is useful to everyone who likes to swim. The bracelet of an inflatable rescue pillow is easily adjustable for a hand with any diameter. An air cushion is inflated in 0.5 seconds with an electric pump that runs on battery power. The whole system is absolutely waterproof.

KINGII costs only 10 dollars. You can buy a set of several pillows.

Armed with personal safety equipment on the water, you can safely go on vacation. To relax at sea, you can think about buying a surfboard. If you can’t stand on the waves, a surfboard will help, which does not need either waves or wind.
