Query: Would not hold a charge

Bought this item to bring on a camping trip to power a cd player and patio lights. Before leaving, we charged the Powerpack for nearly 72 hours, more than the 48 hours suggested by the instruction. The first thing we tried to use was the cd player - the Powerpack worked for 20 minutes then died. We then recharged the Powerpack by plugging into our vehicle's power source and driving around for a few hours sightseeing. The Powerpack green light came on indicating it was fully charged. That night, we waited until it was dark to try the patio lights (1 strand), the lights & Powerpack died after 20 minutes. We weren't expecting to light the area all night, just 2-3 hours which was what the Powerpack should have done. No option for zero stars, so had to pick 1 star.
