Portable 2.4 GHz Wireless Tour Guide System

The BFKK T130 is a complete live sound wireless system with one transmitter and fifteen receivers for group communication. It operates on the 2.4 GHz ISM band and provides ninety-nine selectable channels to avoid crosstalk. A single transmitter can cover a range of 50-60m for guided tours, translation, or assistive listening.

Charging Case and Battery Life

The set includes a charging case with DC 5V 1A USB input for all units. The transmitter uses a 900mAh battery lasting 12h, while each receiver uses a 600mAh battery lasting 18h. LCD screens show status, and automatic or manual ID pairing simplifies setup for many receivers. An AUX input on the transmitter connects external audio sources.

Single-sided Ear-hook Design for Hands-free Use

Each receiver comes with a single-sided ear-hook earphone and lavalier microphone on a long lanyard for hands-free, hygienic wear. Users may also plug in their own 3.5 mm headphones. This kit suits guides, teachers, or interpreters managing groups up to fifteen listeners. It does not suit applications needing two-way talkback, stereo monitoring, or more than fifteen receivers per transmitter.

Questions about this item

How long will the 900mAh transmitter battery and 600mAh receiver batteries last before needing replacement?

The transmitter runs for 12 hours and each receiver for 18 hours per charge; both use built-in lithium cells that are recharged via the supplied USB dock.

Which limit appears first during continuous operation — the 99-channel capacity or the 50-60m range?

The 50-60 metre working range is the practical boundary; you can add many receivers on any of the 99 channels, but signal drops off beyond that distance.

How much heat or fan noise does the charging case produce when all 15 receivers and the transmitter charge overnight?

The case uses simple 5V 1A USB charging with no active cooling, so it stays silent and only mildly warm during a full charge cycle.
