Why This Matters / Understanding the Problem

Let’s be honest—there’s nothing worse than being stranded with a dead battery, only to find your Everstart Maxx 700A jump starter is also out of juice. You bought it for peace of mind, but if you don’t know how to charge Everstart Maxx 700A jump starter fast and safely, that peace can vanish fast.

I learned this the hard way. Last winter, I was stuck in a grocery store parking lot at 9 PM, my car silent despite multiple attempts. My trusty Everstart Maxx 700A? Dead. I’d left it in my trunk for months without checking the charge. Sound familiar?

Jump starters like the Everstart Maxx 700A are powerful tools—but they’re not “set it and forget it.” They need proper charging habits to stay ready when you need them most. Whether you’re a daily driver, a weekend warrior, or just want to avoid that panic moment, knowing how to charge it correctly saves time, money, and stress.

This guide walks you through how to charge Everstart Maxx 700A jump starter fast and safely, with real-world tips, common mistakes to avoid, and answers to the questions I wish I’d known earlier. No fluff. No jargon. Just what works.

What You Need

Before you plug anything in, let’s make sure you have the right tools. The good news? You probably already own most of them.

• The Everstart Maxx 700A jump starter unit (obviously)
• Original AC wall charger (included in the box—don’t lose it!)
• 12V DC car charger (optional)—great for recharging on the go
• Clean microfiber cloth—to wipe dust or grime from ports
• Stable, dry surface—like a table or garage shelf
• Access to a wall outlet or 12V car socket
• Your vehicle (optional, for DC charging)

Pro Tip: Always use the original charger. Third-party cables or adapters may not deliver the correct voltage or current, which can damage the battery or slow down charging. I once tried using a random USB-C cable—don’t make that mistake. It didn’t work, and I wasted 20 minutes.

The Everstart Maxx 700A uses a lithium-ion battery, so it’s smart about charging. But it still needs the right conditions to charge fast and safely. That means no extreme temps, no damp areas, and no cheap knockoff chargers.

Step-by-Step Guide to How to Charge Everstart Maxx 700A Jump Starter Fast and Safely

Step 1: Power Off and Cool Down the Unit

Before you plug anything in, make sure the jump starter is completely powered off. Even if you just used it, give it a few minutes to cool down.

Lithium-ion batteries heat up during use. Charging a warm battery is inefficient and can shorten its lifespan. I learned this after charging mine right after a jump—took forever, and the unit felt hot. Not ideal.

• Press and hold the power button until the LED display shuts off.
• Wait 5–10 minutes if the unit feels warm to the touch.
• Place it on a flat, non-flammable surface—never on a couch, bed, or carpet.

Warning: Never charge a jump starter that’s been dropped, damaged, or is leaking. If the casing is cracked or you smell something odd, stop immediately and contact support. Safety first.

Step 2: Connect the AC Wall Charger (Recommended for Fast Charging)

The AC charger is your best bet for fast and safe charging. It delivers consistent power and is designed specifically for the Everstart Maxx 700A.

• Take the original AC charger and plug it into a standard 110V wall outlet.
• Locate the DC input port on the side of the jump starter—it’s usually labeled “DC IN” or has a small icon.
• Firmly insert the charger’s plug into the port. You should feel a slight click or snug fit.

Once connected, the LED display will light up and show the current battery level. A full charge typically takes 4–6 hours, depending on how low the battery was.

Pro Tip: Plug it in overnight once a month, even if you don’t think you need it. This keeps the battery healthy and ready. I keep mine near my garage outlet so it’s easy to grab and plug in.

Step 3: Monitor the Charging Process

You don’t need to babysit it, but it’s smart to check in occasionally—especially if you’re charging for the first time or after long storage.

• The LED screen will show a percentage or battery icon filling up.
• You’ll see a “Charging” indicator light (usually orange or red).
• When fully charged, the light turns green, and the display shows “100%” or “Full.”

The Everstart Maxx 700A has built-in overcharge protection, so it won’t keep charging once full. That’s a big plus for safety. Still, it’s best to unplug it within an hour of reaching 100% to prevent unnecessary wear.

Personal Insight: I once left it plugged in for 24 hours “just in case.” No damage, but the manual says it’s not needed. Now I set a phone reminder to unplug after 6 hours. Works great.

Step 4: Optional—Use the 12V Car Charger for On-the-Go Charging

Need a quick top-up while driving? The 12V DC car charger is perfect for that.

• Plug the car charger into your vehicle’s 12V socket (cigarette lighter).
• Connect the other end to the jump starter’s DC IN port.
• Make sure your car’s engine is running—charging won’t work well (or at all) if the car is off.

Charging via car is slower—expect 6–8 hours for a full charge—but it’s great for emergencies or long road trips. I used this once during a cross-country drive when my jump starter dipped to 40%. By the time I reached my destination, it was back to 85%.

Warning: Don’t charge while driving long distances if you’re using the jump starter’s USB ports to charge phones or tablets. The combined load can overheat the unit. Use one function at a time.

Step 5: Disconnect and Store Properly

Once charged, disconnect the charger and store the jump starter correctly.

• Unplug the charger from the wall or car first, then remove it from the jump starter.
• Wipe down the unit with a dry microfiber cloth to remove dust or fingerprints.
• Store in a cool, dry place—avoid attics, garages with extreme temps, or near water sources.

I keep mine in a padded case in my trunk, away from direct sunlight. It’s protected, easy to access, and stays at a stable temperature.

Pro Tip: Check the charge level every 3–4 months. Lithium-ion batteries self-discharge over time. If it drops below 20%, give it a quick charge. This prevents deep discharge, which can harm the battery.

Step 6: Test the Unit (Optional but Recommended)

After charging, it’s smart to do a quick test—especially if you haven’t used it in a while.

• Turn it on and check that all LED indicators work.
• Try charging your phone via the USB port to confirm power output.
• If you’re feeling bold, do a dry test jump (without connecting to a car) to see if the clamps spark and the unit powers up.

Don’t worry—this won’t hurt the jump starter. It just confirms everything is working. I do this every few months, and it gives me peace of mind.

Pro Tips & Common Mistakes to Avoid

Now that you know the steps, let’s talk about the real-world hacks and pitfalls most people miss. These come from years of using my Everstart Maxx 700A—and a few “oops” moments.

✅ Pro Tip 1: Use a Smart Power Strip

I use a smart power strip that cuts power when devices are fully charged. It’s a game-changer. No more worrying about leaving it plugged in too long. It’s especially useful if you charge multiple devices in the garage.

❌ Mistake 1: Charging in Extreme Temperatures

Don’t charge your jump starter in a freezing garage or a hot trunk. Lithium-ion batteries hate extremes. Below 32°F or above 113°F? Wait until it’s back to room temp. I once tried charging mine after leaving it in my car overnight in winter. It took twice as long and barely held a charge. Lesson learned.

✅ Pro Tip 2: Label Your Charger

I used to lose chargers all the time. Now I put a bright label on the Everstart charger that says “JUMP STARTER – DO NOT LOSE.” It’s silly, but it works. No more digging through drawers.

❌ Mistake 2: Using Damaged Cables

Frayed wires? Bent connectors? Don’t risk it. I once used a charger with a bent tip. It sparked and shut off. The unit was fine, but it could’ve been worse. Always inspect cables before use.

✅ Pro Tip 3: Keep It Charged Between 40%–80% for Long-Term Storage

If you’re storing it for months (like during summer if you don’t drive much), aim for 50% charge. This reduces battery stress and extends lifespan. I use the “half-charge method” every spring and fall.

❌ Mistake 3: Forgetting to Check the Manual

Yes, the manual is boring. But it has specs you won’t guess—like max charging current and port types. I ignored it once and tried using a 2A adapter. It worked, but slower than the 5A original. Now I keep the manual in the case.

✅ Pro Tip 4: Use the USB Ports to Keep It “Topped Off”

If you charge your phone or tablet from the jump starter regularly, you’re actually helping it stay charged. Just don’t drain it below 20%. It’s like a mini maintenance cycle.

Personal Insight: I keep my jump starter on my desk at work and use it to charge my phone. It stays at 60–80% all the time. When I need it, it’s ready. Win-win.

FAQs About How to Charge Everstart Maxx 700A Jump Starter Fast and Safely

Q1: How long does it take to fully charge the Everstart Maxx 700A?

With the original AC charger, it takes about 4–6 hours for a full charge from 0%. If you’re using the 12V car charger, expect 6–8 hours. The exact time depends on the battery’s starting level and ambient temperature.

I’ve charged mine in 5 hours flat when it was at 10%. In cold weather, it took closer to 7. So patience helps.

Q2: Can I leave it plugged in overnight?

Yes, but not for days. The unit has overcharge protection, so it stops charging at 100%. Leaving it plugged in for 8–12 hours is safe. But don’t leave it connected for a week. It’s unnecessary and can stress the charger.

I do this once a month—charge it overnight, unplug in the morning. Works perfectly.

Q3: What if the charger gets lost or damaged?

Contact Walmart support (Everstart is a Walmart brand). They can replace the charger. In the meantime, you can use a universal 12V DC adapter with 5A output and the correct plug size (5.5mm x 2.1mm, center positive). But I’d still recommend the original for fast and safe charging.

I ordered a replacement from Walmart.com. It arrived in 3 days and worked like new.

Q4: Can I charge it while using the USB ports?

Technically, yes—but I don’t recommend it. Charging while powering devices increases heat and slows down the charging process. It’s not dangerous, but it’s inefficient.

For fast and safe charging, disconnect all USB devices. Save the multitasking for when it’s fully charged.

Q5: Why is my jump starter charging slowly?

Common causes:

• Using a low-amp charger (under 2A)
• Extreme temperatures (too hot or cold)
• Damaged cable or port
• Charging while using USB ports

I once had slow charging because the DC port was dusty. A quick wipe with a dry cloth fixed it. Simple, but easy to miss.

Q6: How often should I charge it?

Charge it:

• After every use
• Every 3–4 months if not used
• Before long trips or winter

Think of it like your phone. Even if you don’t use it, it loses charge over time. Regular top-ups keep it healthy.

Q7: Is it safe to charge in a garage?

Yes, as long as:

• The area is dry and well-ventilated
• No flammable materials are nearby
• The temperature is between 32°F and 113°F

My garage stays around 65°F in winter and 80°F in summer—perfect. If yours gets hotter or colder, bring it inside.
