Giant offers two EnergyPak Charger options; the Smart Charger and the Fast Charger.

Smart Charger

Charge Smart

The Smart charger is compatible with our newest systems, and charging performance is 2.20 hours to charge 80 percent with an EnergyPak Smart 500. 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 time remains the same. Switching between full charge and 60% storage mode can be done by the simple press of a button.

Fast Charger

Charge with Ease

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.
