What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: dimensions are also given as 13cm x 9cm x 7cm and (140x90x65.5)mm, while the listed 5.7-inch screen differs from the feature text's 5.7 * 2.69 Inches display dimensions. The connectivity field lists AUX despite Bluetooth claims, and the alarm-clock field says No despite alarm and snooze instructions. Confirm the exact dimensions, controls and functions for the selected listing.

Who is it for?

A good fit for

Bedside users wanting a clock, Bluetooth speaker, FM radio and phone charging in one tabletop device.
People who want a display with adjustable brightness and a claimed battery backup for use away from its power cable.

Less suited to

Buyers who need consistently quiet low-light display settings or strong speaker volume, given customer reports of brightness and volume concerns.
Anyone relying on dependable wireless charging, straightforward setup or Bluetooth pairing without first weighing the reported mixed experiences.

Customer feedback is mixed on whether the clock works as expected, how easy it is to programme, and the sound, charging and Bluetooth performance. Some find the sound acceptable and setup easy, while others report weak volume, charging failures, pairing problems and unhelpful instructions. Some appreciate the display, but others find even its low setting too bright. These concerns matter for a bedside device whose appeal depends on convenient charging, reliable controls and comfortable overnight brightness.

Frequently asked questions

Does the BT508 have Bluetooth and FM radio?

The listing claims Bluetooth V5.0, FM radio, AUX and TF-card playback. Customer feedback includes concerns about Bluetooth connectivity, so pairing reliability is not assured by the listing.

Can it charge a phone wirelessly?

The listing describes Qi wireless charging and says to connect the clock's Type-C input cable while charging. Customer feedback reports mixed compatibility and some wireless charging failures.

How long does the battery last?

The listing claims up to 10 hours of working time at medium volume from its built-in 2000mAh battery. Treat this as a manufacturer claim rather than a verified runtime.

Can the display be dimmed or turned off?

The listing describes three brightness levels and says a long press can switch the LED display off or on. Customers also report that the lowest setting may still be too bright.
