Key Features and Specifications

The Everstart Maxx 800A is a lithium-ion jump starter with a peak current of 800 amps, making it powerful enough to jump-start most cars, trucks, and SUVs (including those with diesel engines). It also includes:

A built-in LED flashlight with multiple modes (steady, SOS, strobe)
USB ports for charging phones, tablets, and other small electronics
Reverse polarity protection to prevent damage if clamps are connected incorrectly
Smart safety features like over-charge, over-discharge, and short-circuit protection

The battery capacity is around 18,000 mAh (milliamp hours), which translates to roughly 6-8 jump starts on a full charge, depending on the vehicle and conditions. But here’s the thing: All that power comes from a rechargeable lithium-ion battery, which means proper charging is essential for longevity and performance.

Why Proper Charging Matters

Think of your Everstart Maxx 800A like a smartphone. If you leave it plugged in for days or charge it in extreme temperatures, the battery will degrade faster. The same goes for your jump starter. Improper charging can lead to:

Reduced battery lifespan
Inconsistent performance during jump starts
Longer recharge times
Potential safety risks (though rare, lithium-ion batteries can overheat if mishandled)

So, while the Everstart Maxx 800A is built to be durable, treating it with care—especially during charging—will ensure it’s always ready when you need it.

Step-by-Step Guide to Charging Your Everstart Maxx 800A

Now that we’ve covered the basics, let’s get into the nitty-gritty: How to charge your Everstart Maxx 800A jump starter the right way. Whether you’re at home, in the garage, or on the go, these steps will help you get the most out of your device.

1. Use the Right Charging Cable and Adapter

The Everstart Maxx 800A comes with a dedicated charging cable—usually a micro-USB or USB-C to DC barrel plug, depending on the model. Always use the original cable and wall adapter that came in the box. Why? Because third-party chargers might not deliver the correct voltage or current, which can damage the battery over time.

For example, I once tried using a random USB-C cable I had lying around, only to notice the charging process was painfully slow. Turns out, the cable wasn’t rated for high-current charging. Stick to the manufacturer’s recommendations, and you’ll avoid unnecessary headaches.

2. Plug Into a Stable Power Source

Charge your jump starter using a standard 120V wall outlet. Avoid using extension cords, power strips with faulty wiring, or outlets that feel loose—these can cause inconsistent charging or even pose a fire risk. If you’re charging in a garage, make sure the outlet is dry and well-ventilated.

Pro tip: If you’re charging overnight, consider using a smart power strip that cuts off power once the device is fully charged. This prevents overcharging, which can stress the battery.

3. Monitor the Charging Indicators

The Everstart Maxx 800A has a built-in LED display or indicator lights (depending on the model) that show the battery level and charging status. Here’s what to look for:

Red light or “Charging” indicator: The device is actively charging.
Green light or “Full” indicator: Charging is complete.
Flashing lights or error codes: Could signal a problem (more on troubleshooting later).

For example, when I charge mine, I usually see the red light for about 3-4 hours before it turns green. If it’s taking significantly longer, that might be a sign of a faulty charger or battery.

4. Avoid Charging in Extreme Temperatures

Lithium-ion batteries don’t like extreme heat or cold. The ideal charging temperature for your Everstart Maxx 800A is between 32°F (0°C) and 104°F (40°C). Charging in a freezing garage or a scorching car trunk can reduce efficiency and harm the battery.

I learned this the hard way during a winter camping trip. I left my jump starter in the car overnight, and when I tried to charge it the next day, the battery barely budged. It took almost twice as long to reach full capacity because the cold had drained its efficiency. Now, I always store it in a temperature-controlled space.

5. Fully Charge Before First Use

If your Everstart Maxx 800A is brand new, charge it to 100% before your first jump start. This ensures the battery is properly conditioned and delivers maximum power. The manual usually recommends a full charge for the first cycle, so don’t skip this step.

Pro Tips to Charge Faster and More Efficiently

Want to cut down charging time or make the process more convenient? These pro tips will help you get the most out of your Everstart Maxx 800A without sacrificing battery health.

Charge in Short Bursts (If Needed)

Sometimes, you don’t need a full charge—just enough to get through an emergency. For example, if your battery is at 20% and you need to jump-start a car, charging for 30-60 minutes can boost it to 50-60%, which is often enough for one or two attempts. This is a great way to save time when you’re in a hurry.

Just remember: Frequent partial charging (like charging to 50% every time) is actually better for lithium-ion batteries than always draining them to 0% and charging to 100%. So don’t feel guilty about topping it off!

Use a Fast-Charging Adapter (If Compatible)

Some models of the Everstart Maxx 800A support fast charging via a higher-amp wall adapter (like a 2.4A or 3A USB charger). If your manual mentions this feature, you can reduce charging time by 20-30%. For instance, a standard 1A charger might take 4 hours, while a 2.4A adapter could do it in 3.

But here’s the catch: Not all Everstart models support fast charging, so check your user manual first. Using a high-amp charger on an incompatible device can cause overheating or damage.

Keep the Charging Port Clean

Dust, lint, or debris in the charging port can slow down charging or cause connection issues. I once had a jump starter that wouldn’t charge properly, and it turned out a tiny piece of pocket lint was blocking the port. A quick clean with a toothpick or compressed air fixed the problem.

Pro tip: Store your Everstart Maxx 800A in a clean, dry place (like a small bag or case) to protect the ports.

Charge Before Long-Term Storage

If you’re not using your jump starter for a while (like during summer if you live in a cold climate), charge it to about 50-60% before storing it. This prevents the battery from degrading during idle periods. Check the battery level every 2-3 months and top it off if needed.

Troubleshooting Common Charging Issues

Even with the best care, you might run into charging problems. Here’s how to diagnose and fix the most common issues with your Everstart Maxx 800A.

Jump Starter Not Charging

If your device won’t charge at all, try these steps:

Check the cable and adapter: Test them with another device to ensure they’re working.
Inspect the charging port: Look for damage, bent pins, or debris.
Try a different outlet: Rule out power issues.
Let it sit: If the battery was completely drained, it might need 10-15 minutes of charging before the indicator lights turn on.

I once thought my jump starter was broken because it wouldn’t charge. After troubleshooting, I realized the outlet I was using had tripped a breaker. A simple fix!

Charging Too Slowly

Slow charging can be caused by:

A low-amp charger (upgrade to a 2.4A or 3A adapter if compatible)
Using a damaged or low-quality cable
Charging in extreme temperatures
Battery wear (if the device is older than 2-3 years, the battery may degrade)

If none of these fixes work, it might be time to contact Everstart support.

Overheating During Charging

While the Everstart Maxx 800A has built-in safety features, the device might get warm during charging—especially in hot environments. If it’s too hot to touch, unplug it immediately and let it cool down. Avoid charging near flammable materials.

Error Codes or Flashing Lights

Some models display error codes (like “E1” or “E2”) for specific issues. Refer to your manual for a full list, but common causes include:

Reverse polarity (if the clamps were connected incorrectly)
Overvoltage or undervoltage
Internal battery failure

If you see an error code you can’t resolve, don’t panic—Everstart’s customer service is usually helpful with diagnostics.

Best Practices for Long-Term Battery Health

Your Everstart Maxx 800A is an investment, and like any battery-powered device, it needs care to last. Here are the best practices to extend its lifespan.

Follow the 20-80 Rule

Lithium-ion batteries last longer when kept between 20% and 80% charge. Avoid draining it to 0% or charging to 100% every time. For example, if you use it once a month, charge it to 80% and store it. Before a jump start, top it off to 100%.

Store in a Cool, Dry Place

Heat is the enemy of battery life. Store your jump starter in a temperature-controlled area (like your home or garage) rather than the car trunk, especially in summer or winter.

Charge Every 3-6 Months

Even if you don’t use your Everstart Maxx 800A often, charge it every few months to prevent the battery from going into “deep discharge,” which can cause permanent damage.

Keep It Clean and Protected

Wipe it down with a dry cloth occasionally, and store it in a case or bag to protect it from dust, moisture, and accidental drops.
