Charger Check! MillerTech's Dark Speed vs Dual Output

MillerTech’s New Dark Speed Charger vs. The Classic Dual Output

Whether you’re tournament fishing or just grinding on your local honey hole, your batteries are the heartbeat of your boat. If they aren’t charging fast—or correctly—your day is done before it even starts.

Today, we’re breaking down the "old reliable" versus the new heavy hitter from MillerTech.

1. The Tried and True: MillerTech Dual Output

We’ve rigged tons of boats with the Dual Output 12V/36V Charger. It’s been our go-to for years because it’s honest. When MillerTech says it outputs 10 Amps to your cranking battery, it actually delivers 10 Amps. No fluff, just consistent power.

2. The Upgraded Beast: The "Dark Speed" Marine Charger

MillerTech just dropped the Dark Speed, and the name isn't just marketing. They’ve bumped the cranking side output from 10 Amps to 15 Amps.

Why does those 5 extra Amps matter? Let’s look at the math:

If you’re running a standard 135Ah battery and you've drained it to 50%...

BFE Pro-Tip: Cutting your charge time by 2.5 hours is the difference between getting a full night's sleep before a tourney or waking up to a half-dead battery.

The Game Changer: On-the-Go Charging

The real "secret sauce" of the Dark Speed is the DC-to-DC charging indicator.

This charger talks to your outboard's alternator. When you’re running down the lake, an indicator light lets you know that your alternator is now topping off your trolling motor batteries while simultaneously charging your cranking battery.

It’s an all-in-one system that ensures you’re never "running on empty" when you finally drop the trolling motor at your next spot.

The Bottom Line

If you’re looking for a rock-solid, budget-friendly charger, the Dual Output is still a winner. But if you want the fastest recovery time and the ability to charge your 36V system while you’re running the big motor, the Dark Speed is the way to go.
