Ecoxgear EXG510S 5-Watt UHF CB Handheld Radio
Handheld UHF radios are usually a trade-off between range and everything else — battery life, waterproofing, how easy the channel setup actually is. The Ecoxgear EXG510S doesn't cut those corners: IP67-rated, USB-C charging that works from a power bank as well as mains power, and a channel guide built into the screen so the paper chart can stay in the glovebox.
Key features
- 5W / 3W / 1W switchable RF output across 80 UHF CB channels
- IP67-rated waterproof and dustproof housing
- Manufacturer-rated range of up to 17km
- 2500mAh lithium-ion battery, rated for 25 hours, charging via USB-C — direct, through the included cradle, or from a USB-C power bank in the field
- Built-in On Screen Channel Use Guide, showing the recommended use (e.g. "4WD Drivers") for the selected channel
- One-Touch REPLAY, Live RSSI signal display, dual channel watch
- 50 CTCSS and 104 DCS privacy codes, four channel-scan modes
- Removable antenna, compatible with external antennas such as the ATPA230 for extended range
- 3-year warranty with registration (printed on the box)
RV use case
Suits caravan and 4WD convoy groups who need reliable vehicle-to-vehicle communication on tracks, at the beach or through national parks where phone signal drops out — mount it somewhere accessible in the cab or door pocket for quick access.
Pros
- Real-world range holds up — our own test returned a clear link at around 15km, in the same ballpark as the 17km rating
- USB-C charging works from a power bank in the field, not just mains power via the cradle — useful when off-grid for a few days
- The on-screen channel guide is a genuinely useful touch — no more digging for a paper UHF channel chart to work out which channel is for what
- Packaging is well presented, with the full spec sheet and inclusions printed directly on the box
- Backed by a 3-year warranty (with registration), printed clearly on the box itself
Cons
- Sold as a single unit — for vehicle-to-vehicle comms you'll need at least two, so budget accordingly at $199.99 each
Best for
Caravan and 4WD touring groups who want a genuinely long-range handheld radio with the durability and battery life to match, without needing a paper channel guide in the glovebox.
Verdict
Tested in the field with a real ~15km link and clear comms — this earns its place in the door pocket. USB-C charging from a power bank is the standout practical touch, and the on-screen channel guide means less fumbling for a paper chart.
