1. A portable power supply comprising:
an internal power source, the internal power source enclosed within a housing of the portable power supply;
an alternating current (AC) power output;
a direct current (DC) power output;
an input unit configured to receive power from a first external source;
a first power conversion unit configured to convert the power received from the first external source to a first DC power used for charging the internal power source;
an AC power conversion unit configured to convert power output by the internal power source to an AC power used for powering a first peripheral device connected to the AC power output;
a DC power conversion unit configured to convert power output by the internal power source to a second DC power used for powering a second peripheral device connected to the DC power output;
a wireless communication circuit configured to communicate with an external device; and
a controller including an electronic processor configured to receive, via the wireless communication circuit, a value for setting at least one of a charge cutoff threshold and discharge cutoff threshold for the internal power source.
