What Is the Stanley FatMax 700 Jump Starter?

Overview of Features and Specifications

The Stanley FatMax 700 is more than just a jump starter—it’s a portable power station with a few clever tricks up its sleeve. At its core, it’s designed to deliver up to 700 peak amps and 350 cranking amps, which is more than enough to jump-start most cars, SUVs, trucks, and even small boats. But it doesn’t stop there. This unit also includes a built-in 120 PSI air compressor (perfect for inflating tires), a 12V DC outlet, a USB charging port, and an LED work light. It’s like having a mini roadside toolkit in one compact device.

One of the standout features is its reverse polarity protection. If you accidentally connect the clamps backward—something that happens more often than you’d think—the unit won’t spark or damage your vehicle’s electrical system. Instead, it gives you a clear warning light and sound, letting you know to fix the connection. That’s a huge win for safety, especially if you’re using it in the dark or under pressure.

Who Is This Jump Starter For?

The Stanley FatMax 700 is ideal for everyday drivers, weekend adventurers, and even professionals who need reliable power on the go. I’ve used mine for jump-starting my sedan, inflating a flat tire on my mountain bike, and charging my phone during a camping trip. It’s especially great for people who:

• Live in areas with extreme temperatures (batteries die faster in cold or heat)
• Own older vehicles with weaker batteries
• Frequently drive long distances where help might not be nearby
• Want a backup power source for emergencies or outdoor activities

It’s also a solid choice for those who want to avoid relying on jumper cables and another car. No more asking strangers for help or waiting for AAA. With the Stanley FatMax 700 jump starter instructions in hand, you’re in control.

What’s in the Box?

When you unbox your Stanley FatMax 700, you’ll find:

• The jump starter unit with built-in battery
• Heavy-duty jumper cables with clamps
• Air hose with pressure gauge and multiple inflation nozzles
• AC wall charger (for recharging the unit)
• DC car charger (for charging on the go)
• User manual (your go-to for Stanley FatMax 700 jump starter instructions)

Everything fits neatly into the included storage bag, which is a small but thoughtful touch. I keep mine in the trunk with a microfiber cloth to keep it clean and ready.

How to Use the Stanley FatMax 700 Jump Starter: Step-by-Step

Step 1: Check the Charge Level

Before you even think about jumping a car, check how much juice your jump starter has. The Stanley FatMax 700 has a simple battery level indicator on the front—usually four LEDs. Green means it’s charged, yellow is medium, and red means it needs charging. I learned this the hard way once. I tried to jump-start my car after leaving the jump starter in my garage for three months, and the battery was nearly dead. The car barely cranked. Now, I make it a habit to charge it every 2–3 months, even if I haven’t used it.

Tip: If the battery is below 50%, plug it in for at least 4–6 hours using the AC charger. A full charge takes about 12–14 hours, but you don’t need 100% to get the job done—60% or more is usually sufficient for a single jump.

Step 2: Prepare the Vehicle

Turn off the car completely—no radio, no lights, no accessories. Remove the keys from the ignition. This ensures no electrical surge occurs when you connect the clamps. I once left my phone charger plugged in, and the jump starter made a loud beep. Not a big deal, but it’s a good reminder to double-check.

Next, pop the hood and locate the battery. If it’s covered by a plastic shield, remove it carefully. Look for the positive (+) and negative (−) terminals. They’re usually marked, but if not, the positive is typically larger and has a red cap or cable.

Step 3: Connect the Clamps (The Right Way)

This is where the Stanley FatMax 700 jump starter instructions really shine. Here’s the golden rule: **Red to Positive, Black to Ground.**

• Attach the red clamp to the positive terminal of the dead battery.
• Attach the black clamp to an unpainted metal surface on the engine block or chassis—never to the negative terminal of the battery. Why? Because batteries can emit hydrogen gas, and connecting to the negative terminal could cause a spark and explosion. (Yes, it’s rare, but why risk it?)

Pro tip: I use a bolt or bracket on the engine block that’s away from moving parts and belts. It’s safer and gives a better ground connection.

Step 4: Power On and Wait

Once the clamps are secure, press the power button on the jump starter. The unit will beep and light up. Wait about 30 seconds. This allows the internal circuitry to stabilize and deliver a strong, consistent current. I used to skip this step and jump right in—big mistake. One time, the car didn’t start, and I realized I hadn’t waited. After waiting, it started on the second try.

Step 5: Start the Engine

Now, get in the car and try to start it. If it starts right up—great! If it cranks slowly or doesn’t start, wait another 30 seconds and try again. The Stanley FatMax 700 can typically deliver 2–3 jump attempts on a single charge, depending on the battery condition.

Important: If the engine doesn’t start after three tries, stop. There may be a deeper issue—like a bad starter motor or alternator. Continuing to jump could damage the jump starter or the vehicle.

Step 6: Disconnect and Store

Once the car is running, disconnect in reverse order:

1. Turn off the jump starter.
2. Remove the black clamp first.
3. Remove the red clamp.
4. Let the car run for at least 15–20 minutes to recharge the battery.
5. Recharge your jump starter as soon as possible.

I always wipe down the clamps and coil the cables neatly. It keeps them from tangling and makes the next use much smoother.

Using the Air Compressor and Other Features

Inflating Tires and Other Items

The built-in 120 PSI air compressor is a game-changer. I’ve used it to inflate car tires, bike tires, air mattresses, and even a kid’s pool float. The process is simple:

1. Attach the air hose to the compressor outlet on the jump starter.
2. Choose the right nozzle (included for Schrader valves, Presta valves, and inflatables).
3. Connect to the tire or item.
4. Press the air button and monitor the pressure gauge.

The gauge is analog, so you’ll need to watch it closely. It doesn’t shut off automatically, so don’t walk away. I usually inflate to about 5 PSI below the recommended pressure and then check with a digital gauge for accuracy.

Example: My car recommends 32 PSI. I set the jump starter to 27 PSI, then use a handheld gauge to top it off. It saves battery life and gives me peace of mind.

USB Charging and DC Power

The USB port (5V/2.1A) is perfect for charging phones, tablets, and GPS devices. I’ve used it during road trips when my car charger failed. It’s not as fast as a wall charger, but it’s reliable in a pinch.

The 12V DC outlet can power small appliances like coolers, fans, or even a portable air compressor. Just plug in your device, and you’re good to go. I’ve powered a 12V coffee maker at a campsite—total overkill, but it worked!

LED Work Light

The built-in LED light is surprisingly bright and useful. It has a steady mode and a flashing mode (great for emergencies). I’ve used it to change a tire at night, and it lit up the entire undercarriage. It’s not a flashlight, but it’s more than enough for basic visibility.

Tip: The light drains the battery faster than you think. Use it sparingly, and recharge the unit afterward.

Charging and Maintaining Your Jump Starter

How to Recharge the Battery

The Stanley FatMax 700 uses a sealed lead-acid (SLA) battery, which is durable but requires proper care. Here’s how to charge it:

• Use the included AC charger. Plug it into a wall outlet and connect to the unit.
• For on-the-go charging, use the DC car charger. Plug it into your car’s 12V outlet (cigarette lighter).
• Charge until all four battery LEDs are lit. This usually takes 12–14 hours.

Important: Don’t overcharge. The unit has an auto-shutoff feature, but it’s best to unplug it once fully charged. I once left it plugged in for two days, and the battery degraded faster than usual.

Storage Tips

To keep your jump starter in top shape:

• Store in a cool, dry place (not the trunk in summer—heat kills batteries).
• Recharge every 2–3 months, even if not used.
• Keep the unit clean and dry. Wipe it down after use, especially if it gets dirty or wet.
• Avoid dropping or exposing it to extreme temperatures.

I keep mine in a small insulated bag in the back of my trunk. It’s protected from heat and easy to grab.

Signs of Battery Deterioration

Like all batteries, the SLA in the Stanley FatMax 700 will degrade over time. Watch for these signs:

• Longer charging times
• Reduced jump-starting power (car cranks slowly)
• Air compressor runs slower
• Battery won’t hold a charge

If you notice these, it might be time for a replacement. The battery is not user-replaceable, so you’d need to buy a new unit. Most units last 3–5 years with proper care.

Common Issues and Troubleshooting

Jump Starter Won’t Power On

If the unit doesn’t turn on, check:

• Is it charged? Plug it in and wait 10 minutes.
• Are the clamps connected? Disconnect them first.
• Is the power button stuck? Gently press it multiple times.

I once thought mine was dead, but it just needed a full charge. Don’t panic—try the basics first.

Reverse Polarity Warning

If the red and black clamps are reversed, the unit will beep and flash a red light. Simply disconnect and reconnect properly. The Stanley FatMax 700 won’t let you proceed until it’s fixed.

Air Compressor Not Working

Check:

• Is the hose securely connected?
• Is the nozzle the right size?
• Is the battery low? The compressor needs at least 50% charge to run well.

I once tried to inflate a tire with a nearly dead unit. The compressor sputtered and quit. A quick recharge fixed it.

USB Port Not Charging

Try a different cable or device. The port can get dirty over time. I use a small brush to clean it every few months.
