HEYSONG REVERB BT138P portable speaker

The HEYSONG REVERB BT138P is a Bluetooth 5.0 portable speaker built for outdoor and indoor listening. It carries an IPX7 waterproof rating and floats, making it suitable for pool, beach, shower or camping use. A 5000 mAh battery delivers up to 40 hours of playback on a single charge. Rainbow LED lights pulse in time with the music for added atmosphere.

Bluetooth 5.0, AUX-IN and TF card connectivity

Bluetooth 5.0 provides a stable wireless link to phones, laptops, MP3 players, projectors and other Bluetooth devices. A 3.5 mm AUX-IN jack allows wired playback from non-Bluetooth sources. The built-in TF card slot lets you play music directly from a memory card without a paired device. An integrated microphone supports hands-free calls when connected to a smartphone.

Upgrade from non-waterproof or shorter-life speakers

This speaker replaces units that lack IPX7 protection or offer fewer playback hours. The jump is worth it when you need a floating, dust-resistant design that survives full immersion and keeps playing through a full weekend trip. It is not for buyers who require multi-room audio synchronisation, Wi-Fi streaming or a built-in voice assistant beyond phone-based Alexa access.

Questions about this item

How long can the BT138P run at maximum volume before the 5000 mAh battery needs recharging?

Playback time is rated up to 40 hours; actual duration shortens at higher volume levels and with the LED light show active.

Does the speaker become hot or the cooling fan loud during an all-day 40-hour session?

The unit has no cooling fan and relies on passive heat dissipation; the enclosure stays warm but not hot during continuous play.

Which charger must I already own to replenish the 5000 mAh cell?

A standard USB power adapter with a USB-A output is required; the box supplies only the charging cable.
