Zealot S78 Portable Bluetooth Speaker — 120 W Party Power

The Zealot S78 is built for users who want loud, bass-forward sound without sacrificing battery life. You get a 120 W RMS output from two 120 mm woofers and two 42 mm tweeters, spanning a frequency response from 20 Hz to 20 kHz. The 24,000 mAh battery offers up to 40 hours of playback. Thanks to its IPX6-rated housing, you can use it confidently at the pool or beach. For easy transport, it ships with both a shoulder strap and an integrated handle—perfect for barbecues, camping weekends, or indoor gatherings.

Built-In Power Bank and Customizable EQ

What stands out is the dual-role design: a USB-A output turns the internal battery into a phone charger, so you don’t need a separate power bank. Users can switch between three EQ modes—balanced, bass boost, and treble—to tailor the sound to any environment. RGB lighting around the passive radiators even syncs to your music’s beat for visual flair.

Connectivity and Audio Specifications

Bluetooth 5.2 gives you a stable wireless link with roughly 10 m of range. The speaker also supports playback through a 3.5 mm AUX jack, USB flash drive, or TF card slot. Charging is handled by USB-C, and a second USB-A port supports both media playback and reverse-charging for external devices.
