In this post, I’ll walk you through everything I’ve learned about the Everstart jump starter charging time, including real-world tests, tips to speed things up, and what to expect from different models. Let’s get into it!

Understanding the Everstart Jump Starter Lineup

Before we dive into charging times, it’s important to understand that not all Everstart jump starters are created equal. The brand offers several models, each with different capacities, features, and—yes—charging speeds. Think of it like smartphones: a budget model won’t charge as fast as a flagship, but it might still get the job done.

Popular Everstart Models and Their Specs

Here are the most common Everstart jump starters you’ll find at Walmart (their exclusive retailer):

• Everstart 800 Peak Amp: Great for small to midsize vehicles. Compact and lightweight.
• Everstart 1200 Peak Amp: Handles larger engines, including trucks and SUVs.
• Everstart 1600 Peak Amp: The powerhouse—ideal for diesel engines and frequent use.
• Everstart Lithium-Ion Jump Starters (e.g., 1000A, 2000A): Lightweight, portable, and often include USB ports for charging phones.

Each model has a different battery type (lead-acid vs. lithium-ion), capacity (measured in mAh or peak amps), and input charging specs. These factors directly affect how long it takes the Everstart jump starter to charge.

Battery Type Matters: Lead-Acid vs. Lithium-Ion

The type of battery inside your Everstart jump starter plays a huge role in charging speed and overall performance.

• Lead-Acid (Traditional): Found in older or budget models. Heavier, bulkier, and slower to charge (often 8–12 hours). But they’re durable and can deliver high surge currents.
• Lithium-Ion (Modern): Lighter, faster-charging (3–5 hours), and more efficient. They also hold a charge longer when not in use.

For example, the Everstart 800A (lead-acid) might take twice as long to charge as the Everstart 1000A lithium-ion model, even though the latter has a higher peak current. So if speed is your priority, go for lithium-ion.

Charging Time by Model: Real-World Data

Let’s get to the heart of the matter: How long does it actually take? Based on my own testing, manufacturer specs, and community feedback, here’s a breakdown of charging times for popular Everstart models.

Everstart 800 Peak Amp (Lead-Acid)

• Charging Time: 8–12 hours (from 0% to 100%)
• Charger Included: Standard 12V/1A wall charger
• Notes: Takes longer if the battery is deeply discharged. Best to charge overnight.

Personal Tip: I once left mine plugged in for 14 hours after a full discharge. It worked, but I wouldn’t make it a habit—overcharging can shorten battery life.

Everstart 1200 Peak Amp (Lead-Acid)

• Charging Time: 10–14 hours
• Charger Included: 12V/1.5A wall charger
• Notes: Slightly faster due to higher input current, but still slow compared to lithium models.

This one’s a tank—great for trucks, but you’ll need patience. I use it for my F-150, and I charge it every Sunday evening so it’s ready for the week.

Everstart 1600 Peak Amp (Lead-Acid)

• Charging Time: 12–16 hours
• Charger Included: 12V/2A wall charger
• Notes: The longest charging time in the lineup. Ideal for diesel engines but not for last-minute emergencies unless pre-charged.

Note: Charging times may vary based on ambient temperature, charger quality, and battery age.

Factors That Affect Charging Speed

It’s not just about the model. Several real-world factors can speed up or slow down your Everstart jump starter’s charging time. Let’s break them down.

1. Charger Quality and Output

The included charger matters. A 1A charger will take longer than a 2A or 2.4A one. For lithium-ion models, using a higher-output USB charger (like from your phone or laptop) can cut charging time by up to 40%.

Example: I tested the Everstart 1000A lithium model with a 1A charger (took 5.5 hours) vs. a 2.4A charger (took 3.2 hours). Big difference!

2. Battery State of Charge (SOC)

Charging from 0% takes longer than from 50%. Lithium-ion batteries charge faster in the middle range (20–80%) and slow down near full charge to protect the battery. Lead-acid batteries don’t have this feature, so they charge at a more consistent rate.

Tip: If you’re in a hurry, charge to 80% first—it’ll be ready to jump-start most cars. Save the full charge for later.

3. Ambient Temperature

Batteries don’t like extreme cold or heat. Charging a jump starter in freezing temps can take 20–30% longer. In hot weather (above 95°F), some models may reduce charging current to prevent overheating.

I once tried charging my Everstart 800A in my garage during winter (35°F). It took 14 hours instead of 10. Lesson learned: keep it indoors when charging.

4. Age and Battery Health

Older batteries lose capacity over time. If your Everstart jump starter is 2+ years old and takes longer to charge, it might be time for a replacement. Look for signs like:

• Longer charge times
• Reduced jump-starting power
• Swollen casing (especially lithium models)

5. Charging Method: Wall, Car, or Solar?

• Wall Charger: Fastest and most reliable. Use the included adapter or a higher-output one.
• Car Charger (12V Socket): Slower, especially if the car is off. Best for topping up during drives.
• Solar Charger: Very slow (10+ hours), but useful for off-grid use. Only recommended for lithium models with solar input.

For example, charging via car socket while driving might add 10–20% charge per hour—great for maintaining charge, but not ideal for full recharges.

How to Speed Up Charging: Practical Tips

Want to cut your charging time in half? Here are my tested, real-world hacks.

Use a Higher-Output Charger

If your Everstart model supports USB-C or fast charging (check the manual), use a 2.4A or 3A wall adapter. Avoid cheap no-name chargers—they can damage the battery or cause overheating.

My Setup: I use a dual-port Anker 24W charger. One port charges my Everstart 1000A lithium in 3 hours. The other charges my phone. Win-win.

Charge in a Temperature-Controlled Environment

Keep your jump starter indoors when charging—away from cold garages, hot dashboards, or direct sunlight. Room temperature (68–77°F) is ideal.

Charge Before It’s Dead

Don’t wait until the battery is completely flat. A 50% charge takes much less time to top up than a 0% one. I charge mine every 2–3 weeks, even if I haven’t used it.

Use a Smart Charger or Power Bank (for Lithium Models)

Some lithium-ion Everstart models can be charged via a high-capacity power bank. I’ve used my 20,000mAh Anker power bank to charge the 1000A model in about 4 hours—perfect for camping.

Enable Trickle Charging (Lead-Acid Models)

If you have a lead-acid model, consider a smart charger with trickle mode. It keeps the battery at 100% without overcharging. I use a NOCO Genius1 for my 1200A—takes 12 hours but maintains peak charge.

Avoid Using While Charging (Unless Supported)

Some lithium models support pass-through charging (e.g., Everstart 2000A). But for most, using it while charging slows down the process. Best to charge it fully first, then use it.

Common Mistakes and How to Avoid Them

Even with the best gear, mistakes happen. Here are the top pitfalls I’ve seen—and how to dodge them.

1. Using the Wrong Charger

Plugging a 12V lead-acid jump starter into a USB-C port? Bad idea. Always use the correct input. Check the label: “Input: 12V DC” vs. “Input: 5V/2A.”

2. Leaving It Charging for Days

Overcharging can damage lead-acid batteries. Lithium models have built-in protection, but it’s still risky. Unplug once charged.

3. Storing a Discharged Battery

If you store your jump starter at 0%, it can degrade faster. Always store it at 40–60% charge, and recharge every 3–6 months.

4. Ignoring the Manual

Every Everstart model has slightly different charging specs. Read the manual. Seriously. It’ll tell you:

• Optimal charging voltage
• Temperature limits
• Recommended chargers

5. Charging in Extreme Weather

As mentioned, cold slows charging. If you must charge in cold weather, warm the unit first (e.g., bring it inside for an hour). Never charge a frozen battery.

Final Thoughts: Is the Charging Time Worth It?

So, how long does it take an Everstart jump starter to charge? The answer depends on the model, charger, and conditions—but here’s the bottom line:

• Lead-acid models (800A–1600A): 8–16 hours. Great for reliability and power, but slow. Best for home charging.
• Lithium-ion models (1000A–2000A): 3–6 hours. Fast, portable, and efficient. Ideal for on-the-go use.

I’ve used both types, and I’ll be honest: the lithium models are a game-changer. The 3-hour charge time means I can top it up after a weekend trip and have it ready by Monday. The lead-acid ones? They’re dependable, but you need to plan ahead.

My advice? If you want fast charging and portability, go for the Everstart lithium-ion jump starters. If you need high surge current (for diesel engines) and don’t mind waiting, the lead-acid models still deliver.

And remember: a jump starter is only as good as its charge. Whether it takes 3 hours or 12, make sure it’s ready when you need it. Keep it charged, store it properly, and treat it right—and it’ll save your butt more than once.

At the end of the day, knowing how long your Everstart jump starter takes to charge isn’t just about convenience. It’s about being prepared. And in a world where breakdowns don’t send calendar invites, that’s priceless.
