The Guest ChargePro 28210 is a 12v 10 Amp 2-Bank waterproof industrial smart charger. The ChargePRO 5|5 is designed to recharge your batteries and extend battery life for applications where batteries are stored for long periods of time.

The ChargePro 5|5 is a 3-stage fully automatic smart charger designed to charge two 12v group 24 to 31 batteries. The 3-stage charging profile is designed to charge the batteries quickly without the danger of overcharging due to its integrated smart charging technology.

The Guest ChargePRO 5|5 is ideal for two 12-volt batteries such as a starting battery and a trolling motor battery.
