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 the Duracell® Powerpack 300, 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 
Duracell® Powerpack 300. 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 store the clamps in the appropriate holder on each side of 
the Duracell® Powerpack after use.
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.
WARNING: Limitations on use
Do not use this product in connection with life support systems or 
other medical equipment or devices.
