At least one aspect is directed to an uninterruptible power supply including an I/O and an output in electrical communication with the I/O. The UPS also includes electronic circuitry which is adapted to, in a first mode of operation, receive power from the I/O and convert the AC power to DC power. The electronic circuitry is also adapted to, in a second mode of operation, receive DC power and to provide AC power to the I/O. The electronic circuit is further adapted to, in the first mode of operation, convert the DC power to AC power and to provide the AC power at the output.
