The woman who organized our trip to Peru suggested we buy this water purifying system so we could decrease the number of plastic water bottles filling landfills there. It seemed to work like a dream. The battery charge lasted for about 7 days (most of the water for 4 people); I didn’t re-charge it because in the Amazon they provided filtered water. But we liked it and it’s not heavy or bulky.
