Power Draw; Listening To The Am Band; Connecting To An External Battery - Xantrex XPower 400R Owner's Manual

Operation

Power Draw

The AM/FM radio on the back panel is powered by the
internal battery in the XPower Powerpack 400R.
When turned on, the radio draws 30 mA, allowing you to use
the radio for more than one month when the XPower
Powerpack 400R is fully charged.

Listening to the AM Band

Due to signal interference, you cannot listen to the AM band
while using the XPower Powerpack 400R to operate an AC
appliance.

Connecting to an External Battery

You can extend battery operating times by connecting the
XPower Powerpack to a larger external battery.
For example, an external 60 Ah battery gives approximately
four times the operating time of the XPower Powerpack
internal 20 Ah battery.
WARNING: Fire hazard
Never allow jump-start cables' red and black clamps to touch each
other or another common metal conductor. This could cause
damage to the unit and/or create a sparking/explosion hazard.
Always disconnect the jump-start cables from the unit after use and
clip the plastic guard over the jump-start cable port.
WARNING: Fire hazard
Jump-start cable clamps must be connected positive to positive (red
clamp to battery "+") and negative to negative (black clamp to
battery "–"). A reverse polarity connection (positive to negative)
may cause damage to the unit and/or create a sparking/explosion
hazard.
