By my request, I’m breaking down the battery backup systems I actually use at real events—specifically Jackery—and why batteries have become a “super important” part of DJing going into 2025, 2026, 2027 and beyond. Power isn’t something most DJs think about until it’s too late, and with the grid getting tighter and peak-demand warnings becoming more common, having a battery plan is just smart business. In this video I walk through the exact Jackery units we keep at Fusion, what each size is good for, and how I decide what to bring to weddings, ceremonies, and corporate gigs. I start with the Jackery 300 (and the older 240s) that I’ve been using for years on ceremony rigs—simple math: watts in vs hours out. I also show you how I measure real-world power draw with a Kill A Watt meter, because speakers can vary and you need to be conservative. Then I get into the Jackery 1000/2000 class for “save the event” situations—like the corporate event where the venue lost power and we kept audio, mics, and even a projector running long enough to play a must-see video. Finally, I cover the big boy: the Jackery 5000. This thing is heavy, but it’s a monster for UPS-style backup, outdoor “no generator noise” setups with solar, and even acting like a power buffer so you don’t trip breakers when subs hit hard. If you’re serious about events, you need battery options in your kit.
