The NEW PopUp WiFi Beast Mach 3 packs two of all the essentials, because "two is one; one is none". Two battery ports double the run-time and allow you to hot-swap, so there's no down time when you're adding fresh batteries during your show. Run your whole network off battery power, or just add a battery as a UPS for instant seamless failover in case of a generator glitch. The whole PopUp WiFi event internet range is compatible with the super-popular Milwaukee M18 and Dewalt XR batteries, so you can easily get your hands on the right battery types from your shed, your buddy's toolbox, or your local Home Depot! #eventinternet #productionprofessionals #eventnetwork #bondedcellular #battery
