The RAM Tough-Dock Power + Dual USB with Latch for Zebra ET4x 10" Tablet (RAM-HOL-ZE21PD2NLLU) features a top latch design for securing the tablet without wear and tear on the dock itself. Power is provided via a 5.5mm DC barrel connector and allows you to keep the device charged through the pogo pin contacts when the device is docked. A dual USB Type-A pigtail connector is provided for adding up to two additional input devices. The dock also includes space in the back for tablet add-ons such as the Zebra Expansion Back, PowerPack Battery, and GDS Ergo accessories like the GDS Roto-Mag and GDS Hand-Stand. To mount this dock, pair any RAM 4-hole AMPS or 75mm x 75mm VESA pattern bases for attaching a double socket arm in order to complete your mounting solution. Take the solution a step further by taking advantage of the built-in 2-hole mounting plate compatible with RAM 2-hole diamond base for additional device mounting such as a phone, scanner, printer, or any other handheld device.
