Designed to be the most versatile Jobsite Radio Charger on the market. The unit is able to run off and charge all DEWALT slide pack battery packs including 12V, 20V and FLEXVOLT packs at 3 AMPs when plugged into an AC outlet. The unit is designed to include woofers, tweeters and air ports to provide clear and rich sound at all volume levels. An over sized device storage box protects devices from worksite conditions and includes an Aux and 2.1 AMP USB charging port for convenient device charging. 2 AC Power outlets on the side of the unit allows you to plug in additional tools or chargers without occupying additional outlets on the wall. AVRCP (Audio Visual Remote Control Protocol) allows you to control your device from the radio interface so you can keep the device in a safe place and skip to the next song or hit replay on the radio interface.
