Vvinca T-388 Walkie Talkies 3 Pack 22 CH 3KM Range

Three-pack UHF radios for children

The Vvinca T-388 set supplies three handheld two-way radios operating on 22 pre-set channels between 462.5625 MHz and 462.7125 MHz. Each unit weighs 0.249 kg and measures 6.1976 x 11.6078 x 15.0876 cm. The pack targets families with children aged 3 to 13 who want simple push-to-talk communication during outdoor play, camping or hiking. It is not suited for users who need programmable frequencies, repeater access or licensed-band operation.

Continuous reception and transmission

A built-in 600 mAh lithium cell powers each radio for up to 48 hours on a single charge when used intermittently. Voice-operated transmission activates the microphone without pressing a button, keeping the circuit active during extended conversations. The USB Type-C 3-in-1 cable recharges all three units from a single 6.5 V source in roughly two hours. Buyers who require field-swappable cells or multi-day operation without mains access should look elsewhere.

Thermals noise and power draw

The compact enclosure remains cool to the touch during typical receive and short transmit cycles because the low-power UHF circuitry draws minimal current from the 600 mAh pack. No internal fan is present, so operation is silent apart from the speaker audio. The integrated flashlight adds negligible load. The radios are water-resistant for splashes but not rated for immersion or heavy rain.
