H777 Civil Walkie Talkie UHF 400-470MHz Single Band Black Two Way Radio

This H777 civil walkie talkie is a compact two way radio for short-range voice communication where mobile networks may be weak or where instant push-to-talk contact is useful. It operates on a single band and single frequency in the UHF 400-470MHz range. The rated voltage is 3.7V DC, output power is below 5W, and it uses a 1000mAh Li-ion battery. Antenna impedance is 50Ω. The working temperature range is -30 to +60°C, covering cold and hot conditions. It is black, measures 60×33×115mm excluding the antenna, and weighs 180g. Plug options are EU, UK or US, and pack choices are 1, 2, 3 or 4 pieces.

Features and Construction

The H777 uses a simple single band, single frequency UHF design. The stated 50Ω antenna impedance and sub-5W output power are part of its core radio specification. A 1000mAh Li-ion battery provides the power source, and the 3.7V DC rated voltage matches that battery type. The black casing keeps the unit discreet, while the 180g weight and 60×33×115mm body make it easy to carry.

Material and Build

The radio is supplied in black and powered by a Li-ion battery with a stated 1000mAh capacity. The antenna is specified at 50Ω impedance. Rated voltage is 3.7V DC. Output power is below 5W. No waterproof rating, impact rating or housing material beyond colour is given in the source data, so those details are not claimed here. The plug type is chosen at purchase from EU, UK or US options.

Size and Practical Fit

Dimensions are 60×33×115mm (L×W×H) not including the antenna, and the unit weighs 180g. That makes it a pocketable or belt-friendly size for carrying during a shift or event. Packing size is 185×110×95mm. No belt clip, holster or lanyard is stated in the source data, so those are not included in the description.

Uses and Placement

With UHF 400-470MHz single band operation and a -30 to +60°C working range, this radio suits short-range coordination in a variety of indoor and outdoor settings. It is not a long-range or multi-channel system based on the source data. The black colour and 180g weight support handheld use. Plug choice depends on the region where it will be charged.

Event or Professional Use

For events, site work or venue coordination, a simple single frequency radio can be enough when all users are on the same channel. The stated UHF 400-470MHz range and below-5W output power are the relevant specifications. No range in kilometres, channel count, privacy codes or headset compatibility is given, so those should not be assumed. The 1000mAh Li-ion battery is the stated power source.

Everyday Home Use

At home, this walkie talkie can be used for short-distance contact around a property, campsite or local area where mobile signal is poor. The 60×33×115mm size and 180g weight make it easy to store and carry. Working temperature -30 to +60°C means it can be kept in cold or hot conditions within that range. No weatherproofing is stated, so it should be kept away from heavy rain or standing water.

Benefits and Buying Value

The main practical benefit is straightforward single band UHF communication with a rechargeable 1000mAh Li-ion battery and a wide stated working temperature range. Multiple pack options allow a set to be bought for a small team or family. Colour is black. Plug type is selected to suit the region. No pricing, savings or competitor comparisons are claimed because the source data does not provide them.

Reuse and Low Maintenance

The Li-ion battery is rechargeable, so routine use does not require disposable batteries. Charging time and battery lifespan are not stated in the source data, so no claims are made about those. The 50Ω antenna impedance and 3.7V DC rating are fixed specifications. Keep the unit within the -30 to +60°C working range. No specific cleaning or servicing instructions are given.

Why Choose This Product

Choose this H777 civil walkie talkie if you need a single band, single frequency UHF radio in the 400-470MHz range with a stated 1000mAh Li-ion battery, 180g weight and 60×33×115mm body. It is available in black with EU, UK or US plug options and in 1, 2, 3 or 4 piece packs. It does not include waterproofing, long-range or multi-channel features in the source data, so it suits simple short-range voice coordination rather than complex radio systems.
