"An increadible unreliable piece of equipment."1.0 starson by IvanNavarro
Pros: Charging 2 units at the same time is great. Had the XP4000 that used 12 VAC charger, more universal.
Cons: This unit (for the price) is a real NO GO!!! unit broke in 7 days. Didn't keep it's charge. When charging red light stays on and nothing happens.
Summary: With so many reliable companies making these power packs UPC and others, this one is to stay away.
