The first step in troubleshooting battery drain issues is to gain an understanding of how much power your gadgets are actually drawing from your car’s electrical system. While using 12-volt outlets is generally safe in moderation, larger devices can tax your battery beyond its charging capabilities.

Some common electrical gadgets and their average power draws:

  • Cell phone chargers – 5-10 watts
  • Tablets – 10-20 watts
  • Laptop computer chargers – 45-60 watts
  • Small portable fridges/coolers – 50-100 watts
  • Medium-sized powered speakers – 200-400 watts

As you can see, something as small as a laptop charger draws significantly more power than a USB-powered smartphone. Hooking up an entire sound system or a large cooler can draw hundreds of watts, quickly depleting a typical 50-60 Ah lead-acid car battery.

Understanding your devices’ energy demands gives you a better picture of what’s safe to power in your Hyundai for short periods versus what may require additional precautions.

Using 12-Volt Outlets Safely

Hyundai vehicles come equipped with at least one 12-volt power outlet to conveniently charge and power electronics on the go. These cigarette lighter-style ports provide an easy way to hook up small gadgets, but you’ll need to take some basic steps to avoid excessive battery drain when utilizing them:

  • Always keep the engine running – The vehicle’s alternator is required to replenish the battery when external devices are drawing current. Never use 12-volt outlets with the engine off for more than a brief period.
  • Stick to low-power devices – As illustrated above, today’s smartphones, tablets, and other USB-charged gadgets typically pose little threat to your battery. But hooking up more power-hungry electronics can quickly overwhelm the charging system.
  • Avoid long charging sessions – Try to limit your use of 12-volt outlets to relatively short stretches of time. The longer they’re used continuously, the greater the strain on the battery. Take breaks from charging when possible.
  • Check connections – Faulty connections that provide resistance can generate excess heat that saps battery power. Make sure plugs are making solid contact in the ports. Wiggle and adjust as needed.
  • Alternate outlets – If equipped with multiple 12-volt ports, consider switching periodically between them during long drives. This helps spread the electrical load more evenly.

In order to avoid being left with a car that won’t start, it’s important to recognize the telltale signs that your battery is being drained faster than it can recharge:

  • Difficulty starting the engine
  • Dimming or flickering headlights
  • Sluggish electrical component performance
  • Reduced power from the radio/infotainment system
  • Battery indicator light coming on

Any of these symptoms can indicate that plugged-in devices are pulling more power than the alternator can keep up with. Discontinue use of the outlets and allow the car to run for a period to recharge the battery.

You may also notice these effects mainly after the engine has been switched off, as the battery has been depleted by gadgets still drawing current in the absence of the alternator.

Constantly observing your car’s performance and electrical operation can help detect battery drain issues before you’re left with a completely dead battery.

Using a Power Inverter as an Alternative

For powering high-draw electronics like laptops, small TVs, or gaming consoles, a DC-to-AC inverter can provide an alternative to directly using your Hyundai’s 12-volt outlets.

Inverters convert the DC current from your car’s electrical system into standard 120-volt AC current that can safely accommodate just about any device. While pricier inverters can handle outputs up to 300 watts, even an inexpensive 100-150 watt inverter can power most electronics without putting your battery at risk.

Some tips for successfully using an inverter in your vehicle:

  • Select an inverter with sufficient wattage for your devices
  • Use the direct 12-volt connection for best performance
  • Avoid extremely long runtimes to prevent battery drain
  • Start the engine periodically to recharge, if needed
  • Mount the inverter securely so it doesn’t shift while driving

For full-time high power draws, upgrading to an additional auxiliary battery that’s isolated from your starting battery can provide reliable performance without compromising your ability to start the car. But for most purposes, an inverter paired with smart power management is an affordable way to expand your electronics capabilities.

Maintaining Your Hyundai’s Battery
