Leave the laptop at home
Use the WeCAi cable to connect a DDJ-WeGO or DDJ-ERGO to your iTunes library on a mobile device running Algorridim's djay 2 app. Or get to grips with video mixing using Algorridim's vjay app.
USB power supply
The WeCAi includes a USB connection for supplying power to the WeGO/ERGO via a standard USB power adaptor or a USB mobile battery, so you can play out even where traditional power sources cannot reach.
