Short answer: the JBL Charge 6, if you are buying new. The JBL Charge 4 ranks higher than the W-King D8 Mini (#63 vs #135 of 175 medium speakers) but is discontinued; its replacement, the JBL Charge 6, is rated 4.2/5 at $119.95 and is still sold new.
The JBL Charge 4 is the better-sounding, deeper-bass option. Doubles as a power bank for charging phones/tablets. Its bass reaches about 54Hz before falling 10dB, against 63Hz for the W-King D8 Mini. At 2.1 lbs (960 g) it weighs noticeably less than the W-King D8 Mini at 2.8 lbs (1.26 kg). Watch for: 1 Oval driver.
Why pick the W-King D8 Mini: 30W output with switchable indoor/outdoor EQ modes. It has an adjustable EQ, which the JBL Charge 4 lacks. It plays in stereo from a single unit, unlike the JBL Charge 4. Watch for: Recessed midrange, harsh treble.
Buy the JBL Charge 6, the replacement for the discontinued JBL Charge 4; it is rated higher for sound quality than the W-King D8 Mini.
