We believe that just about every driver should use a dash cam.

They can help protect drivers in the case of an accident, traffic violation, fraud scheme, and more.

There are a couple different types of dash cams on the market, with two of the main categories being battery powered and capacitor powered.

Today, we’re going to look at the best capacitor dash cam options to help you find the right one for you.

But before we do that, let’s explain more about capacitor dashboard cameras, and how they work!

Dash Cam: Battery vs Capacitor

Almost all dash cameras draw their power from your car’s battery, usually through the cigarette lighter or another dashboard power source.

With that said, these devices do need a small amount of built-in power, in order to properly save footage once your car shuts off.

So, all dash cams have a power source built in – either a battery or a capacitor.

In the dash cam world, there has been a long debate over the benefits of battery vs capacitor dash cams.

In the end, each type has pros and cons, but overall, capacitor dash cams are better than battery-powered cams. Here’s why:

  • Capacitors are more reliable than batteries, in general
  • Capacitors are more heat-resistant than batteries (particularly important if you live in a warm climate and in need of dash cam for hot weather)
  • Capacitors are typically used in higher-quality cameras(such as 4k dash cam), while batteries are often used to power cheap dash cams

The only real downside is that capacitors are a bit more expensive than batteries.

As a result, the best capacitor dash cam might be a bit more pricey than the best battery powered dash cam – but the cost will be worth it for improved durability and reliability.
