Abstract
A portable power supply including a housing, a circuit, a battery power source, and an electronic-ink display. The housing supports a battery power source and a power outlet. The circuit is supported by the housing and includes a power input from the battery power source, a power output on the power outlet, and an inverter electrically connected between the power input and the power output. The battery power source includes a battery cell electrically connectable to the power input. Power is transferrable from the battery cell to the circuit to be output through the power output. The electronic-ink display is configured to display one or more parameters associated with the portable power source.
Claims18
A portable power source comprising:
- a housing supporting a battery power source and a power outlet;
- a circuit supported by the housing and including:
- a power input from the battery power source,
- a power output on the power outlet, and
- an inverter electrically connected between the power input and the power output, the battery power source including:
- a battery cell electrically connectable to the power input, wherein power is transferrable from the battery cell to the circuit to be output through the power output;
- and
- an electronic-ink display configured to display one or more parameters associated with the portable power source,
- wherein a controller is configured to automatically adjust a contrast ratio or color of the electronic-ink display based on a time of day,
- wherein the electronic-ink display includes an electronic gauge having a refresh rate of more than 3 seconds, and
- wherein the electronic-ink display includes a multi-segment display.
A portable power source comprising:
- a housing supporting a battery power source and a power outlet;
