Battery-Powered Backpack Sprayer

Depending on battery-pack voltage and pump-generated spray force, the Battery-Powered Backpack Sprayer reportedly allows one to spray for up to 10 hours on a single charge. Most makes/models eliminate the need to continually pump up the sprayer for steady spray force. Most also feature piston pumps, long spray wands, multiple spray settings, and carrying harnesses.

Cost: $150-$400, depending on battery system, capacity, accessories, etc.
