Frequently Asked Questions
Always reference the Product Instruction Manual for detailed instructions.
Q: Does the FatMax come charged?
A: Yes. You will receive your FatMax in a partially charged state. Ideally, we suggest that you charge your FatMax when you receive it, after each use, and every 30 to 60 days to maintain the battery capacity.
Q: How long does it take to charge the FatMax?
A: Charging time for the FatMax depends on the level of discharge. If the FatMax is deeply discharged, it can take up to 12-14 hours to completely recharge. The LED indicators will let you know when the charge is complete.
Q: How often do I need to recharge my FatMax?
A: As a general rule, you should charge your FatMax 24 to 48 hours immediately after you receive it as well as after every use. Periodically recharging the FatMax will maximize the efficiency of the internal battery and ensure that it's always ready when you need it. To be prudent, when FatMax is not in use, we recommend that you recharge it every 30 to 60 days for about 12 hours or until the battery status indicators show full.
Q: How do I recharge my jump starter/power station?
A: The FatMax comes with a 22"L charging extension cord. Plug the FatMax into any standard wall outlet using this cord until the green charging LED illuminates solid or flashes.
Q: How do I know when my FatMax is fully charged?
A: Your FatMax has a battery status indicator. When all of the LED lights illuminate and the green LED lights/flashes, the unit is fully charged.
Q: How long will my FatMax keep a lamp on in a power outage?
A: The FatMax can keep a 120-Watt bulb in a lamp on for up to 2 hours.
Q: What is the output of the unit for my auto and home appliances?
A: The peak output of the jump starter is 1000 amps. The Professional Power Station output is 500 watts, which is appropriate to run home electronics.
Q: What happens if I connect my jump starter backwards or in reverse?
A: It is very important to review the safety warnings and instruction manual before you use your FatMax. Be advised that your FatMax must be turned OFF when connecting to any battery. Reversing the polarity of a jump starter that is in the ON position upon connection may cause irreparable damage and will void the product warranty.
For your safety, the FatMax has a reverse polarity alarm. This will give you an audible alarm and visual indication if you connect the cables in reverse. If you connect the cables in reverse, you must disconnect them immediately and connect in the correct fashion.
Q: How large of a car/truck can I jump with the FatMax?
A: The jump starter output of the FatMax is 500 amps, so it is rated for personal autos, trucks, and vans.
Q: What is the difference between a jump starter and a battery charger?
A: A jump starter is a product with an internal portable battery with jumper cables attached. It must be recharged and can boost a vehicle without the need of another vehicle or being plugged into household AC power.
A battery charger has no battery and must be plugged into household AC power to function. Battery chargers are designed to charge automotive batteries or for maintaining a charge.
Q: Why don't the LED indicators illuminate when I press the battery status button?
A: The battery status button may need to be pressed and held for several seconds to get battery status indication. If your FatMax was not properly maintained and is completely depleted, the indicator lights may not illuminate.
Q: Why is there no output to the clamps?
A: The power switch must be turned ON. The FatMax has a safety feature that prevents sparking and arching until a proper connection is established.
