JBL Gray Portable Bluetooth Speaker with 10W Output and Built-In Battery

Pros

• · Built-in 1200–2000mAh rechargeable battery charged over USB, so no separate power source is needed.
• · Bluetooth 5.0 connection with 10W rated output from a single driver.
• · Catalog ratings of 100Hz–20kHz frequency response and signal-to-noise ratio of at least 75dB.
• · Two finish options (black, white) with store three-guarantee after-sales service.
• · Light 0.9 kg net weight in a 220 × 106 × 105 mm body, listed as standard size.

Cons

• · IPX2 water resistance is splash-level; the IP67 rating cited for JBL's Flip line does not apply here.
• · Independent reports on JBL portables describe battery failures within months and runtime shorter than advertised at higher volume — the claims on file cover the Charge and Flip lines, not this model, so they say nothing verified about this unit.
• · The feature block lists brand CXW while the title says JBL; confirm branding and model with the seller before ordering.

Fit notes

One size, listed as standard: a 220 × 106 × 105 mm body at 0.9 kg net. That's one-hand portable and shelf-friendly, not pocket-sized. Single driver, so plan for mono playback rather than stereo separation.

Buy if

You want a 0.9 kg, 10W mono speaker for casual indoor listening or dry outdoor use, with Bluetooth 5.0, USB charging, and a built-in battery, and you're fine confirming brand and battery details with the seller before ordering.

Skip if

You need waterproofing for pool or rain exposure — the catalog lists IPX2, splash-level only — or you want documented runtime figures before buying. Also skip if you expect stereo; the listing specifies one driver.
