A method of providing power to a plurality of devices comprising:

• operating an uninterruptible power supply (UPS) in a first mode of operation to provide AC power derived from input AC power to a first device;
• inserting a battery into a UPS housing of the uninterruptible power supply;
• operating the uninterruptible power supply in a second mode of operation to provide AC power derived from DC power from the battery to the first device;
• removing the battery from the housing;
• and
• with the battery removed from the UPS housing, charging a mobile device using the battery,
• wherein the battery is configured to charge the mobile device when the battery housing of the battery is disposed within the UPS housing.

An uninterruptible power supply (UPS) comprising:

• a battery contained within a battery housing, the battery having at least one battery module within the battery housing and configured to provide battery power, the battery housing having a first connector mounted on the battery housing;
• a UPS housing having a battery compartment for removably containing the battery housing of the battery, the UPS housing having a second connector mounted within the battery compartment, the second connector being configured to mate with the first connector;
• a first input configured to receive input power from an AC power source;
• and
• at least one output configured to provide output AC power derived from the input power in a first mode of operation and configured to provide output power derived from the at least one battery module in a second mode of operation;
• wherein the battery includes means for charging a mobile device with the battery removed from the UPS housing, the battery being configured to charge the mobile device coupled to the third connector when the battery housing of the battery is disposed within the UPS housing and when the battery housing of the battery is removed from the battery compartment of the UPS housing.
