Boombox
The best boombox size battery powered speaker with a SD card slot is the Zealot ZE41: $219.95 Aliexpress Amazon
Pros: The absolute best value for the bass performance, play time and max volume in the boombox class.
Cons: The heaviest and biggest boombox speaker around. A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding.

Party
The best party size big party battery powered speaker with USB stick playback is the JBL Partybox 330: $629.95 Amazon Bhphotovideo
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
