TelDaykemei c28 Bluetooth 5.0 Audio Adapter

The TelDaykemei c28 is a Bluetooth 5.0 adapter that adds wireless audio to any device with a 3.5 mm auxiliary port. It works as both a receiver and a transmitter for headphones, speakers or car stereos. The compact black unit suits listeners who want cable-free playback from phones, tablets or computers.

Sustained Bluetooth 5.0 streaming over 3.5 mm

Bluetooth 5.0 maintains a stable link up to 10 metres in open space during extended listening sessions. The adapter runs for about 4 hours on a single charge while continuously transmitting or receiving audio. A Micro USB port recharges the internal battery at 5 V and 0.5 A for the next session.

Low-power operation with Micro USB charging

The adapter draws minimal power while streaming, so it stays cool and silent during normal use. No fan or active cooling is required because the 5 V 0.5 A input keeps thermal output negligible. Charging is handled through the same Micro USB connection used for power.
