Giant offers two EnergyPak battery charger options—Smart Charger and Fast Charger. The Smart Charger is the most powerful way to charge your battery, while the more compact Fast Charger is easier to pack and carry. Here’s a look at each.

Smart Charger

The Smart charger is the fastest way to charge your EnergyPak and is compatible with our newest systems. It takes 2.2 hours to charge 80 percent with an EnergyPak Smart 625. The Smart charger also helps extend battery life. When the EnergyPak is charged more than 500 cycles, this charger uses a lower voltage, so the cells are used in a less energetic way. Battery life is extended while total charging times becomes slightly longer. Switching between full charge and 60% storage mode can be done with the simple press of a button.

Fast Charger

The 4A charger helps you charge your E-bike with greater ease. It’s small and lightweight, so it’s easy to carry, and it lets you charge your EnergyPak on or off the bike.
