Understanding Your Rexing Dash Cam’s Power Needs
When you think about a dash cam, it’s easy to assume it just runs on its internal battery. But here’s the thing: that’s not really how most dash cams, including Rexing, are designed to operate.
Why Power Matters for Dash Cams
Dash cams are all about continuous recording. They need a constant, stable power supply to function reliably. Imagine missing crucial footage because your battery died – that’s exactly what dash cams are built to prevent. Most Rexing dash cams, by design, need to be connected to a power source while recording. If you disconnect them from power, they’ll typically shut down within a few seconds, or maybe last 5-10 minutes if they have a small internal battery for emergencies.
Built-in Batteries vs. External Power
Many dash cams, Rexing included, come with a small internal battery or a supercapacitor. Now, don’t get me wrong, these aren’t there to power the device for hours on end like your phone battery. Instead, they serve a specific, critical purpose: they provide enough juice to safely save the last recording file and properly shut down the device if the main power source is suddenly cut off, like in an accident. Some models, especially newer ones, use supercapacitors, which are great for longevity and handling extreme temperatures, but they don’t hold a charge for long at all. So, if you’re ever wondering “how long does it take to charge a dash cam battery” for a Rexing, remember that its primary power comes from your car, not its tiny internal power reserve.

Decoding Rexing Dash Cam Chargers
Alright, let’s talk about the actual ways you can power your Rexing dash cam. You’ve got a few main options, each with its own pros and cons. Rexing M3 3 Channel: Your Ultimate Guide to a Safer Drive
The Standard Car Charger Cigarette Lighter Adapter
This is probably the most common and easiest way to get your Rexing dash cam running right out of the box. Most Rexing dash cams come with a 12V car power cable that plugs right into your car’s cigarette lighter or 12V DC power outlet.
How it works: You just plug one end into your car’s power socket and the mini-USB or Type-C end depending on your Rexing model into the dash cam itself. When your car turns on, the dash cam powers up and starts recording. When you turn your car off, the dash cam typically shuts down automatically after a few seconds.
Pros:
- Super simple installation: Literally plug and play.
- Included with most dash cams: You usually don’t need to buy anything extra to get started.
Cons:
- Occupies a power outlet: If you only have one, it might conflict with other devices you want to charge.
- No parking mode: Since the power cuts off with your car’s ignition, your dash cam won’t record while your car is parked and off. This is a big one if you’re looking for 24/7 surveillance.
- Visible wires: Unless you’re meticulous with cable routing, you might have a wire dangling across your dashboard, which can be a bit messy.
USB Cables: More Than Just Data
While many dash cams use a USB connection, it’s crucial to understand that it’s usually for power, not just data transfer. Rexing dash cams commonly use Mini-USB or, for newer models like the R4, L4, and RH2 series, a Type-C USB port for power. Your Ultimate Guide to the Rexing V3 Plus Dash Cam: Front and Cabin Coverage for Peace of Mind
Can you use any USB charger? This is a common question, and the answer is not always. Your dash cam needs a specific voltage usually 5V and amperage often 1.5A to 2A, sometimes 3A for Type-C models to operate correctly. Using an incompatible charger, especially one that doesn’t provide enough power, can cause issues like constant reboots, slow charging, or even prevent the dash cam from turning on at all. Rexing recommends using only manufacturer-approved chargers to prevent damage and ensure proper function.
Rexing dash cam cable types:
- Mini-USB: Common for many older Rexing models, like various V1 series.
- Type-C USB: Found on newer models, offering more robust power delivery and often faster charging.

- Is the car charger working? Try plugging another device into the car charger port. If that doesn’t work, the fuse in your car’s cigarette lighter might be blown, or the charger itself could be faulty.
- Is the USB cable damaged? Inspect the cable for any visible kinks, cuts, or bent pins.
- Try a different power source: If you’re using the car charger, try a wall-type phone charger or a fully charged power bank with the correct USB cable Mini-USB or Type-C. Laptops and in-car USB ports sometimes don’t supply enough power.
- Reset your dash cam: Most Rexing models have a small reset button often a tiny hole you’d push with a paperclip. This can sometimes clear minor software glitches.
- Internal battery issue: If your dash cam only turns on when plugged in but won’t auto-power on with the car, the internal battery might be depleted or failing. While the main battery is for emergencies, it does play a role in auto-on functionality. Replacing the internal battery is a potential DIY fix for experienced users.
Slow Charging or Battery Drain
Remember, Rexing dash cams are designed to run on continuous power, not primarily off their internal battery. So, “charging” typically refers to the small internal battery or supercapacitor getting topped up. If you notice your dash cam struggling to stay on or the internal battery draining quickly if it even holds a charge for a few minutes, here’s what could be happening:
- Inadequate power supply: The charger might not be providing enough amperage. For instance, if your dash cam needs 2A and the charger only provides 1A, it might not keep up.
