RLN6433A Vehicle Travel Car Charger for Portable Radios - Reliable

In this review the RLN6433A vehicular travel charger is assessed for users who rely on two-way radios in vehicles and need a dependable charging solution. The charger is a direct replacement for several OEM car chargers and is aimed at technicians, fleet drivers, and first responders who want a compact charging base that plugs into a vehicle cigarette lighter and provides regulated charging on the go. The single biggest reason to buy is simple: it converts a vehicle power outlet into a fast, protected charger that accepts a range of compatible batteries and radio models with a clear front LED status indicator.

Key Features

• Vehicle plug and cord: The charger plugs directly into the vehicle cigarette lighter so radios can be charged without changing vehicle wiring or removing the battery.
• Regulated charging: Built-in voltage regulation and microprocessor control help protect batteries from overcharge and provide consistent charge rates for Ni-CD, Ni-MH and Li-ion cells.
• Rapid charge capability: The unit supports a charging rate up to 1000mAh per hour which reduces downtime for commonly used batteries.
• Complete mounting kit: It ships with a custom RLN6433A base, mounting bracket, screws and coil cord so the charger can be secured inside a vehicle for repeated daily use.
• Broad compatibility: Works with multiple radio lines and battery models such as PMNN4077, PMNN4409 and APX4000 or XPR series radios, making it useful across mixed fleets.

Who It's For

The RLN6433A is best for professionals who need a permanent or semi-permanent in-vehicle charging point for portable radios, including service vehicles, patrol cars, delivery vans and utility trucks. It suits organizations that already use compatible batteries like PMNN4066 or PMNN4409 and want a rugged, regulated solution that avoids relying on handheld chargers.

It is less suitable for users who rarely use radios in vehicles or who prefer multi-bay desktop chargers for simultaneous charging of several batteries. Home users who only charge at a desk may find a standard AC charger more convenient.

Pros & Cons

Pros

• Direct cigarette lighter connection makes installation quick and non-invasive for most vehicles.
• Included mounting bracket and coil cord let the unit be secured and positioned for regular use.
• Microprocessor charge control and LED status indicator provide safer, visible charging progress.
• Wide radio and battery compatibility reduces the need for multiple vehicle chargers.

Cons

• Designed for a single radio/battery at a time, so fleets needing simultaneous multi-battery charging will need additional units.
