DETAILS
Overview
Uniden's smallest UHF radio, now with USB-C
A single UH45 Max walkie talkie in grey, with 80 UHF CB channels and Kid-Zone Plus. Use it on its own or add it to an existing UH45 set.
It's small enough for a pocket or belt clip, with a built-in LED torch and up to 20+ hours of operating time on 3 x AAA batteries. Kid-Zone Plus locks the radio to a private code and voice scramble, so kids only hear the family. Need more radios? The UH45-2 Max Twin Pack pairs straight up.

Frequently asked questions
How far will they reach?
Uniden quotes a typical range of 3+km, line of sight. Hills, trees and buildings cut that down. In duplex mode the radios can talk through a UHF CB repeater for more distance, depending on where the repeater is and the terrain.
What batteries do they use?
Each radio takes 3 x AAA batteries, which are not included. Use standard alkaline or NiMH rechargeables. The USB-C cable only charges NiMH rechargeables, and you need a USB wall adaptor (not included). Charge new rechargeables for 6 to 7 hours before first use.
How does Kid-Zone Plus work?
Press the KID-Z key and the radio locks to CTCSS code 10 and voice Scramble 2. Radios set the same way hear each other, and other users on the channel are blocked out. It's on by default.
Will it talk to my other UHF CB radios?
Yes, it uses the standard 80 UHF CB channels. With Kid-Zone Plus on it only hears radios set to CTCSS 10 and Scramble 2, so turn Kid-Zone off to talk to other radios on an open channel. It pairs easily with a UH45-2 Max Twin Pack.
Are they waterproof?
No. Uniden says not to expose the UH45 Max to rain or moisture.
