Duracell DPP-600HD great !

got it at 99.00 and free ship. the unit does what it says it will. great to take to campsite or for a short power outage to run a pc, tv, lamp and fan for 3+hours. it takes a long time to charge from the ac adaptor unit at only 1 amp output( 35 hours if dead) but car cord is much faster. nice unit that worked well and at a fair price.
