Think of this as a friendly chat over a cup of coffee, where I share what I’ve learned from charging, testing, and using my own Everstart 750A over the past year.

What Makes the Everstart 750A Special?

The Everstart 750A is a lithium-ion-powered jump starter designed for 12V vehicles, including cars, trucks, SUVs, and even small boats. With 750 peak amps, it can handle most gas engines up to 6.0L and diesel engines up to 3.0L. But beyond its jump-starting power, it’s packed with features: a built-in LED flashlight, USB charging ports (perfect for topping up your phone), and a compact design that fits easily in your trunk or glove box.

One of the best things? It doesn’t require another vehicle to recharge—unlike traditional jumper cables. That means you can charge it at home, at work, or even in a parking lot. But here’s the catch: if you don’t charge it correctly or leave it sitting for months, its performance can degrade. That’s why understanding how to charge the Everstart Jump Starter 750A is crucial. Let’s dive into the details.

Charging Basics: What You Need to Know

Before plugging anything in, it’s important to understand how your Everstart 750A charges and what tools you’ll need. Unlike your phone, which can be charged with just about any USB cable, the Everstart requires a specific setup. But don’t worry—it’s simple once you know the steps.

What Charging Equipment Comes in the Box?

When you open your Everstart 750A package, you’ll typically find:

• The jump starter unit (with built-in battery)
• A wall charger (AC adapter)—usually 12V/1A or 12V/2A
• A 12V car charger (cigarette lighter plug)
• A smart charging cable with built-in safety features (this connects the charger to the jump starter)
• Jumper clamps (with reverse polarity protection)
• A user manual (keep this handy!)

The key here is the smart charging cable. It’s not just a regular cable—it has circuitry that prevents overcharging, overheating, and short circuits. Never use a third-party cable. I once tried with a generic USB-C cable (don’t ask why), and the jump starter wouldn’t accept the charge. Lesson learned: always use the original cable.

Understanding the Charging Port and LED Indicators

On the side of the Everstart 750A, you’ll find a small, round charging port. It looks like a DC barrel jack (similar to laptop chargers). Plug the smart cable into this port, then connect the other end to either the wall charger or the car charger.

Once connected, the LED indicators on the front will light up to show the charging status:

• Flashing red light: Charging in progress
• Solid green light: Fully charged
• Red and green alternating: Error (e.g., overheating, bad connection)
• No light: No power or faulty connection

I remember the first time I charged mine, I thought it was broken because the red light kept flashing. Turns out, that’s normal! It took about 3 hours to go from 20% to 100%. The manual says a full charge takes 3–5 hours, which matches my experience.

Step-by-Step Guide: How to Charge the Everstart 750A

Now let’s get into the actual process. Charging your Everstart 750A is straightforward, but following the right order prevents mistakes. Here’s how to do it safely and effectively.

Step 1: Find a Safe, Dry Location

Start by choosing a spot that’s:

• Indoors or under cover (avoid rain or snow)
• Well-ventilated (don’t charge it in a sealed trunk or closet)
• Free from flammable materials
• On a flat, stable surface (to prevent it from falling)

I keep mine on a shelf in my garage, away from tools and liquids. Once, I left it charging on the back seat of my car during a summer heatwave. The temperature inside reached over 100°F, and the jump starter shut off automatically due to overheating. The safety feature worked—but I learned to avoid extreme temps.

Step 2: Connect the Smart Cable to the Jump Starter

Take the smart charging cable and plug it into the DC port on the side of the Everstart 750A. You’ll feel a slight click—this means it’s secure. Make sure the connection is tight. A loose cable can cause intermittent charging or no charging at all.

Tip: If the cable feels stiff, don’t force it. Wiggle it gently until it seats properly. I once pushed too hard and bent the pin inside—had to get a replacement cable from Walmart (where I bought it).

Step 3: Choose Your Charging Method (Wall or Car)

You have two options:

Option A: Wall Charging (Recommended)
Plug the AC adapter into a standard wall outlet (110–120V). Then connect the smart cable to the adapter. This is the fastest and most reliable method. The wall charger typically delivers 12V/2A, which means a full charge in about 3–4 hours.

Option B: 12V Car Charging
If you’re on the go, use the cigarette lighter plug. Plug it into your car’s 12V socket (make sure the car is turned on or the socket is always live). This method is slower—usually takes 5–7 hours—and isn’t ideal if your car battery is weak.

I use wall charging at home and the car charger only when I forget to charge it overnight. Once, I tried charging it in my car while parked at a rest stop. After two hours, it only went from 10% to 35%. Not great, but better than nothing.

Step 4: Monitor the Charging Process

Once connected, the red LED will flash. This means charging is active. Here’s what to do:

• Check the LED every 30 minutes for the first hour.
• If the light alternates red/green, unplug immediately and check the connections.
• Do not cover the unit—heat builds up during charging.
• Never leave it unattended for more than 6 hours (even if fully charged).

The Everstart has an auto-shutoff feature, but I still unplug it once the green light comes on. Better safe than sorry. I once left it charging overnight, and the next morning, the green light was on—perfect. But I still unplugged it right away.

Step 5: Unplug and Store Properly

When the solid green light appears, unplug the cable from the wall or car first, then disconnect it from the jump starter. Store the unit in a cool, dry place. Avoid extreme temperatures—don’t leave it in your car during winter or summer.

I keep mine in its original box with the accessories. It’s easy to grab in an emergency, and the box protects it from dust and moisture.

How Often Should You Charge Your Everstart 750A?

This is a common question: “Do I need to charge it after every use?” Not necessarily. But here’s the rule of thumb I follow—and it’s backed by the manufacturer.

After Every Jump Start

If you use the Everstart to jump-start a vehicle, recharge it as soon as possible. A single jump can drain 20–30% of the battery. If you don’t recharge it, the next time you need it, it might not have enough power.

I learned this the hard way. I used mine to help a neighbor last winter. I didn’t recharge it for two weeks. When I tested it, it only delivered 400 amps—below the 750A rating. Once I charged it fully, performance returned to normal.

Monthly Top-Up (Even If Not Used)

Lithium-ion batteries degrade if left uncharged for long periods. Everstart recommends charging every 30–60 days, even if you haven’t used it.

I set a monthly reminder on my phone. On the first weekend of each month, I plug it in for 2–3 hours. It usually goes from 70% to 100%. This keeps the battery healthy and ready.

Before Long-Term Storage

If you’re not going to use your jump starter for more than 3 months (e.g., storing it in a vacation home), charge it to 50–60% before storing. Full charge or deep discharge can shorten battery life.

I once stored mine fully charged in a cabin for 5 months. When I returned, the battery wouldn’t hold a charge. The service center said it was due to overcharging stress. Now, I charge it to 50%, store it in a cool place, and recharge fully when I need it.

Common Charging Problems and How to Fix Them

Even with the best care, issues can happen. Here are the most common problems I’ve faced—and how to solve them.

Problem 1: No LED Lights Come On

Symptoms: Plug in the charger—nothing happens. No flashing, no lights.

• Check the wall outlet with another device (e.g., phone charger).
• Inspect the smart cable for damage (frayed wires, bent pins).
• Try the car charger instead—if it works, the wall adapter might be faulty.
• Let the jump starter sit for 10 minutes—sometimes it needs to reset.

I once had a dead outlet in my garage. I thought the jump starter was broken. Switched outlets, and it charged fine.

Problem 2: Red/Green Flashing Light

Symptoms: The lights alternate red and green—this is an error code.

• Unplug immediately to prevent damage.
• Check for overheating—feel the unit. If it’s hot, let it cool for 30 minutes.
• Inspect the clamps—if they’re connected to the unit, disconnect them.
• Clean the charging port with a dry cloth or compressed air.

This happened to me when I accidentally left the clamps attached while charging. The internal circuit detected a short. Disconnecting them fixed it.

Problem 3: Slow Charging

Symptoms: It takes much longer than 3–5 hours to charge.

• Use the wall charger—car charging is always slower.
• Check the cable and adapter—older ones may not deliver full power.
• Charge at room temperature—cold or hot environments reduce charging speed.

During winter, I noticed it took 6 hours instead of 3. Once I moved it inside, charging returned to normal.

Pro Tips for Maintaining Your Everstart 750A

Charging is just one part of the puzzle. To keep your Everstart 750A in top shape, follow these pro tips from my experience.

Keep It Clean and Dry

Dust, moisture, and dirt can damage the charging port and internal components. After use, wipe it down with a dry, soft cloth. If it gets wet, dry it immediately and let it air out for 24 hours before charging.

I keep a microfiber cloth in the storage box. It only takes 30 seconds to wipe it down after a jump start.

Test It Every 3 Months

Don’t wait for an emergency to find out it’s not working. Every 3 months, turn it on and check:

• The LED display (if it has one)
• The flashlight
• The USB ports (plug in a phone)
• The battery level (should show 80–100%)

I do this on a Sunday morning. It’s become part of my routine.

Store It with the Clamps Disconnected

Always remove the jumper clamps before storing. Leaving them connected can drain the battery slowly over time.

I once stored mine with the clamps attached. After a month, it was at 40%. Now I always disconnect them.

Replace the Battery When Needed

The lithium-ion battery lasts 3–5 years with proper care. If you notice:

• It won’t hold a charge
• It takes much longer to charge
• It delivers weak jumps

It might be time for a replacement. Contact Everstart customer service or check with the retailer.

Below is a quick reference table for charging and maintenance:

Action	Frequency	Notes
Full charge after jump start	After every use	Prevents low power during next use
Monthly top-up	Every 30–60 days	Even if not used
Storage charge	Before long-term storage	Charge to 50–60% only
Test all features	Every 3 months	Flashlight, USB, battery level
Clean unit	After every use	Wipe with dry cloth

Your Everstart Jump Starter 750A is more than a tool—it’s a lifeline when you’re stranded. But it only works if it’s charged and maintained properly. By following this guide, you’ll ensure it’s always ready to jump your car, charge your phone, or light up a dark roadside.

Remember: charge it after every use, top it up monthly, and store it correctly. Use the original charger and cable. Watch the LEDs. And don’t forget to test it regularly. It only takes a few minutes—but it could save you hours of frustration (and a tow truck bill).

I’ve used mine in freezing snow, scorching heat, and even to power my phone during a camping trip. It’s never let me down—because I take care of it. Now that you know how to charge the Everstart Jump Starter 750A the right way, you can do the same. Keep it charged, keep it safe, and stay ready for anything the road throws at you.
