Amp Control in a Compact Case

This unit uses an automatic 12V/24V DC output stage with a 7-stage charge profile and up to 300W input. Output is rated 20A on 12V systems and 10A on 24V systems for lead-acid battery types and 12V LiFePO4. The LCD displays charge voltage, output current, and charge status for in-use checks.

What the Modes Actually Do

Power comes from a 100–240V AC, 50/60Hz outlet and AC is converted internally and delivered to the battery via clamp leads. The charger detects battery system voltage (12V or 24V), then runs the programmed stages and transitions to a low-current maintain stage. Seasonal settings adjust charge control automatically based on internal temperature sensing. Pulse mode is intended for idle batteries reading above 0.3V.

Clamp, Select, Monitor, Disconnect

Attach the clamps to the battery posts with correct polarity, then select the battery chemistry and setting before starting. Place the unit on a stable surface with airflow clearance; the internal cooling fan runs during higher current operation. This charger is for charging sessions rather than permanent connection, and the clamps should be removed after the charge cycle ends.

Product Benefits:

  • Voltage Detection: Identifies 12V or 24V battery systems automatically before charging.
  • Charge Program: Uses a 7-stage charge sequence and then switches to a low-current maintain stage.
  • Output Rating: Delivers up to 20A on 12V systems or up to 10A on 24V systems, depending on the detected system voltage.
  • Display Readings: LCD shows charge voltage, output current, and charge status during operation.
  • Cooling Operation: Integrated fan runs during higher current operation and requires airflow clearance around the housing.

What I really appreciate is that it automatically switches between 10A and 20A depending on the battery size and state of charge. I use it on both my car and my boat and I don't have to fiddle with settings every time I switch between them.

DOES THE JOB.

I've charged several batteries with this and every single one came back to full without any drama. Simple, reliable, and the LCD is a nice touch.

Exactly what I needed for the garage.

had a cheap charger before this that would just dump a constant current into the battery with no regulation. this one actually adjusts the charge rate automatically and the LCD shows you exactly what's happening the whole time, so you always know it's doing the right thing.

solid charger, no complaints so far.

Love it 🔋!

Kept my battery topped up over the winter and it started first time in spring. Very pleased with that result.

it goes into a maintenance mode once the battery is full instead of just shutting off. noticed this when I left it connected overnight and the display showed it had switched over automatically. that kind of attention to battery health is exactly what I wanted.

Great little unit.

My last charger from a different brand would get so hot after an hour that I was genuinely afraid to leave it unattended. This one stays cool to the touch even after long charging sessions, which makes a huge difference when I'm charging overnight in the garage.

Bought one of these for my dad who drives an older truck. He was skeptical because he'd had a charger fry his battery before, but this one handles both 12v and 24v without any issues and he says it's been rock solid since he got it.

Works on my car and my ride-on mower without any issues. Glad I picked this one over the cheaper options.

decent quality for the price, feels sturdy and the clamps are nice and thick.

ok the automatic mode detection for 12v vs 24v is genuinely great. charged my car battery one day and then used it on my van the next and it just figured it out on its own. no manual switching, no digging through the manual.

Works perfectly.

Does exactly what it should. The display makes it easy to keep track of things and I never have to wonder if it's working properly.

I told my neighbor to grab one of these after she mentioned she was nervous about using a charger on her newer car with all the sensitive electronics. She's been using it for a while now and hasn't had a single problem, says it's gentle and controlled the whole way through.

Really happy with this.

The LCD display is honestly more useful than I expected. You can see the voltage, the charge percentage, and the current being delivered all at once, so there's no guessing about whether your battery is actually recovering or just sitting there.
