The Bosch GAX 18 V-30 offers you the option of charging batteries with differing voltages and configurations in the same charger. In addition, it features a USB port with which you can charge your phone, tablet or other devices at the same time.
The GAX 18 V-30 is a multi-functional charger; it takes both Bosch 10.8V and 18V professional Li-ion batteries. The GAX 18 V-30 charges sequentially, meaning the unit charges the first battery you insert before beginning to charge the second. An indicator flashes when the battery is at 80% full. The USB port is available at any time.
Having a dual battery charger saves carrying two different chargers if you are on the move, while the wall-mounting bracket (included) saves you space in the workshop.
