Let’s dive in!
Why Every Driver Needs a Dash Cam
Dash cams are no longer just an extra accessory—they are an essential security tool for modern drivers.
1. Dash Cams Provide Clear Evidence in Accidents
Without video footage, accident disputes can turn into stressful “he said, she said” situations. A high-quality dash cam ensures that you have clear proof of what happened, which can be crucial when dealing with other drivers or authorities.
2. Protect Your Car from Theft & Vandalism
A dash cam with parking mode records even when the car is off, capturing suspicious activity such as break-ins or hit-and-run accidents. However, to run parking mode without draining your car battery, you need a dash cam external battery pack.
3. Ideal for Rideshare & Teen Drivers
- Rideshare drivers: Protect yourself from false claims and ensure passenger safety.
- Parents of teen drivers: Monitor your teen’s driving habits and keep an eye on their vehicle when parked.
Why BlackVue is the Best Dash Cam Brand
At Bankstown Sound, we trust BlackVue dash cams for their advanced technology and reliability. Here’s why:
1. Superior Video Quality
With Full HD and 4K Ultra HD options, BlackVue dash cams capture crisp, clear footage in any lighting condition—perfect for identifying license plates and road signs.
2. Cloud Connectivity for Remote Access
With BlackVue Cloud, you can remotely access footage, receive alerts, and even live-stream from your camera. However, this feature requires additional parts and a subscription.
3. Reliable & Discreet Design
BlackVue dash cams are small, sleek, and discreet, making them ideal for both personal and professional use.
Why You Need a Dash Cam External Battery
While a dash cam is a great investment, it needs continuous power to work at its best—especially for parking mode and long recording sessions. That’s where an external battery pack comes in.
1. Keeps Parking Mode Running Without Draining Your Car Battery
If your dash cam is hardwired to your car battery, it can:
❌ Drain your battery overnight
❌ Trigger low-battery warnings
❌ Reduce your battery’s lifespan
A dedicated external battery eliminates these issues, keeping your dash cam powered without affecting your vehicle’s electrical system.
2. Extends Recording Time
A car battery alone can only support a dash cam for a few hours when the engine is off. However, with an external dash cam battery pack, you can get:
✅ 12+ hours of recording with standard batteries
✅ 24+ hours of recording with high-capacity models
This is ideal for:
- Overnight parking at home or in unfamiliar areas
- Long-term airport parking
- Fleet and rideshare vehicles that need continuous surveillance
3. Protects Your Car’s Electrical System
Modern cars have sensitive electrical systems, and continuously drawing power from the main battery can lead to wear and electrical issues. Using an external battery ensures your car’s main power supply remains untouched.
How to Choose the Best Dash Cam Battery Pack
When selecting an external battery for your dash cam, consider the following:
1. Battery Capacity & Runtime
Choose a battery with enough capacity to support at least 10-12 hours of parking mode recording. Some high-end models offer 24+ hours.
2. Fast Charging & Efficiency
Fast-charging batteries are useful for short trips but long parking durations.
3. Compatibility with Your Dash Cam
Ensure the battery is compatible with your dash cam model, especially if you use BlackVue dash cams.
