The Bosch GAA18V-24N 18V Portable Power Adapter helps users quickly power up their other most important tool – their cellphone – anywhere on the jobsite using an 18V Bosch battery. The adapter works with all Bosch 18V Li-ion batteries to deliver power to any 5V USB or 12V DC device(s), and it is capable of charging two devices simultaneously. It is designed to withstand jobsite conditions and keep charging. The output on this charger is 2.4 Amps, to get phones ready to use in a hurry. If users simultaneously charge two devices, each output is 1.2 Amps. The adapter has a port compatible with Bosch heated jackets, so users can power their jackets with 18V Lithium-ion batteries to greatly increase the heating zones' runtime. It includes a metal belt clip for additional user convenience. It prevents overcharging by going into sleep mode after charging a device. The charger adapts to the device being charged, allowing for the optimal charging current to the device. It has a power on button to activate the charger for each charging session, and to begin powering the heated jacket.

Awesome accessory, a must have!!!
Just purchased this recently and glad that I did. I had in mind to use exclusively at jobsite for charging my phone and tablet. After using it for a few weeks I keep it in my truck and use it not just for work and personal use as well. Works great with heated jacket and keeping phone charged in the deer stand. Really is a perfect addition to my 18v lineup. thanks bosch
