CAUTION
Do not expose the XPower Powerpack to temperatures over 104 °F
(40 °C).

WARNING: Explosion hazard
Do not use this product where there are flammable fumes or gases,
such as in the bilge of a gasoline- powered boat, or near propane
tanks. Do not use this product in an enclosure containing
automotive-type lead acid batteries. These batteries, unlike the
sealed AGM battery in XPower Powerpack, vent explosive
hydrogen gas which can be ignited by sparks from electrical
connections.
When working on electrical equipment, always ensure someone is
nearby to help you in an emergency.
WARNING: Heated surface
Ensure at least 2" (5 cm) air space is maintained on all sides of the
XPower Powerpack. During operation, keep away from materials
that may be affected by high temperatures such as blankets, pillows
and sleeping bags.
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.
