Please choose options for all selected products I bought this unit in April 2014 so have had it for five months. I've used all of its functions BUT jump-starting and I'm happy with it. It does everything I expected it to do. To repeat what others have said, it did not come with an instruction book, and it doesn't come with any AC power cord--you plug the female end of an extension cord onto a sort of male plug flush with the panel. User reviews alerted me to these issues. I don't have a problem with its not having its own cord. I have a BIG problem with its not having an instruction book and that's why I only gave it four stars. I couldn't even find a way to download it from the Black & Decker site; when I contacted customer service they were able to locate and email me a PDF. Nothing in the instruction book gives a rated watt-hour capacity, but some guidelines on the outside of the box suggest it is roughly 240 watt-hours, and some informal tests I made--plugging a lamp into the AC outlets--confirm this. I didn't hover over it with a stopwatch, but it powered a 60-watt floor lamp ABOUT 4 hours, and a 7-watt incandescent nightlight for over 20 hours at which point I got tired of running the test. The big thing I want to add to what others have said is that, as with many rechargeable battery devices, the state-of-charge indications are not very accurate and can lead to an impression that the battery is not holding a charge well when, in fact, it is. There are two red lights and a green light. The manual says, a little vaguely, "Two red and one green battery status indicator lights indicate a full battery. Only one red battery status indicator lights indicates that the unit needs to be recharged." a) During charging, I am almost certain that when the green light first comes on, the battery is NOT yet fully charged. It would take a lot of long experiments to prove this. Since the manual says that the battery cannot be damaged by overcharging from AC, to be sure of a full charge I believe it is wise to charge for as long as convenient--for several hours after the green light comes on, anyway. b) IMMEDIATELY after charging, the green light DOES go on when the test button is pressed. But sitting idle, unused, just a few hours later, it will not. I only get the two red lights. As nearly as I can tell, as long as there are two red lights, the battery is still fully charged or very close to it. The fact that you don't see the green light does not mean the battery is losing charge, or not much anyway. c) When you use it to power a device, it drops QUICKLY to one right light. At a rough estimate, using 10% or 15% of its full capacity can drop it to one red light. For example, charging an electronic device through a USB port overnight (2.5 watts, 25 watt-hours) drops the indication to one red light. One red light does NOT mean "almost discharged." It should be read as meaning merely "no longer 100% charged." This is all frustrating and means you don't really know where you stand when you are using it--you almost always see one red light. One red light can mean almost discharged, one red light can mean >80% charged. My experience, though, is that this sort of behavior is typical of charge indicators for lead-acid gel cells. The instruction book notes that the USB ports supply "5 volts/500mA DC power to an external USB-powered device." This is low-power and similar to what the ports on a computer supplies. It means that, just as with a computer USB port, electronic devices like our iPad and Kindle do charge--but very slowly, and maybe not to a full 100%. If your gadget comes with an AC-powered "fast charger" you should experiment to see whether you are better off using the fast charger plugged into the inverter port. The main reason I bought the unit was to have a backup for my CPAP machine. I have a rechargeable battery unit specially designed for my CPAP machine that I bought from the manufacturer for $350. I never needed to use the Black & Decker unit "for real" as backup, but I eventually did a test run and it powered my CPAP machine overnight with no problems. Oh, and I did use it to inflate my car tires, because I just wanted to add a couple of pounds and I thought it would be a good opportunity to test the device and it worked. The pressure gauge works but is no substitute for an accurate gauge. It took about 1-2 minutes per pound of pressure added on my small car's tires. In short, the unit works as expected, seems well-designed and well-thought out. I won't know for a few years how durable it really is (though all previous experience with lead-acid gel-cells has been pretty good). How long does a BLACK& DECKER power Station last?A standard charge will last about 30 days. A battery status light in the front of the unit tells the amount of charge ranging from high to low. I have used the unit on low to jump start a mid size truck with no issues.
Can you replace the battery in a Black & Decker portable power station?You have to install your replacement batteries in the same original configuration they came out and are required to use your existing Black & Decker PS400JRB Power Station Portable Jump Starter hardware and cables to reconnect the replacement batteries when applicable.
How long does it take to charge a Black and Decker portable power station?Typically as a general rule 24 - 48 hours immediately after purchase and after every use. It is also recommended to recharge every 30 - 60 days for approximately 12 hours or until the battery status indicators show full when the product is not in use.
How do you use a Black and Decker portable power station?Simply connect the clamps to the battery, turn on the switch and start your vehicle. The reverse polarity alarm will alert you when there is an improper connection. The built-in USB port comes in handy to charge your phone and electronic devices.
