A pressure-activated flotation device for use with an electronic device includes an attachment feature, chemicals, a container, a removable cap, an inflatable tube, and a pressure-activated valve. The inflatable tube is fluidly connected to the container and is configured to inflate with the expanding gas when the chemicals are exposed to a liquid. The pressure-activated valve leads from the outer surface of the container to the inner volume of the container and includes a one-way valve that opens to allow liquid to flow to the inner volume of the container when the pressure-activated flotation device is submerged in the liquid to a depth where the pressure applied against the pressure-activated valve by the liquid is greater than an actuation pressure. The one-way valve also closes when the expanding gas generates a gas pressure inside the inflatable tube that exceeds a threshold.

Self-inflating device

A self-inflating device can include a container configured to receive a chemical compound, a one-way valve covering an opening leading to an inner volume of the container, and an inflatable portion fluidly connected to the inner volume of the container and configured to inflate with gas produced when the chemical compound is exposed to water. The inflatable portion can be configured to inflate when a gas pressure inside the self-inflating device exceeds a water pressure outside the self-inflating device. As the inflatable portion inflates with gas produced by the chemical reaction of the chemical compound, the inflatable portion can increase in volume and can displace water in a body of water. Consequently, the overall buoyancy of the self-inflating device can increase, causing the self-inflating device to rise in the water column toward the surface of the body of water where a user can easily retrieve the self-inflating device, as well as any object that is attached to the self-inflating device.
