Verdict: The JBL Charge 5 outperforms the Bose SoundLink Flex in raw power (30 W vs 5 W) and battery life (20 h vs 12 h) according to RTINGS, while the Bose offers a lighter, more portable package at a lower price (per CNET). However, the Charge 5’s bulk and lack of a companion app may deter users seeking a sleek travel speaker (per Wirecutter). Overall, JBL is the stronger choice for outdoor, long‑duration use, whereas Bose excels for on‑the‑go listening.
Bose SoundLink Flex lists at $149 while JBL Charge 5 lists at $179 — Bose SoundLink Flex undercuts JBL Charge 5 by $30 (20%).
