The slider module is battery operated, but if AC power is available, the AC/DC adapter will work better. It takes power from the car when used outside. You don't have to worry about running out of battery, so you can rest assured.
I recently received SliderPLUS v5 Long & Slide Module v3. I can honestly say these are the BEST in the business. Super excited and extremely satisfied. Next I'm going for the Focus Module and HeadPLUS or HeadPLUS PRO So I can create my own filming when I don't have an extra hand. Ps EDELKRONE support is phenomenal. The SliderPLUS v5 Long is a manual ball bearing slider, but it supports the optional Slide Module v3 attachment for motion control, and other edelkrone motorized add-ons can be incorporated for fully synchronized multi-axis motion control operated via a single iOS/Android app. When paired with the Slide Module v3, the SliderPLUS v5 Long can be mounted on a tripod at an incline of up to 22.5° with up to 5.5 lb loads.
The attention to detail and feel of quality on all of edelkrones products is very impressive. The interchangeable plug system for the AC adaptor is really clever and allows easy swap outs of your kit when travelling.
I love the interchangeable plug connections for the different countries. They allow reliable power-supply.
The equipment works very well. It is intuitive and easy to use. I am looking forward to playing with it in different environments.
