this old toll has and old AGM battery inside
none made last this long ever, and if not kept then internal battery charged it will go bad in 6 months due to sulfation. !

The battery is finito, dead replace it.

Most likely the battery in your device is worn out , This can happen a number of ways depending upon the type of battery . Standard lead acid batteries as used in automobiles fail this way when they are discharged completely too many times . Lithium and some other types of batteries can be sensitive to being left on the charger too long or NOt being discharged completely before being charged . In any case you need new batteries

Sure, you can find it on amazon... here: Amazon com Husky jump start adapter . I hope I have helped. Cheers

Hi, I bought a new Black & Decker one of these and when I got it home and charged it, it acted the same way. I assume it has an internal battery. These gel-cell spill-proof lead acid batteries will dry out and one cell will loose power for a load, but will indicate "full". 99% of these batteries have replacements available on line under S L A (spill-proof lead acid) batteries, or if you have a friend with a WW GRAINGER account, they stock them.

There are two possibilites: the first is the over 400W power draw, the other is how you have the inverter connected. Do you have the inverter connected directly to the battery terminals (the clips) not the outlet plug (cigaretter lighter)? This is needed for any load over 80W and under 400W. (the inverter can handle a load demand over the 400W limit but only for short periods (800W).)

What is the load that your PC pulls (Is it a laptop or a desktop)? The laptop in my home has either a 65W or a 90W load (depending on the battery and the AC adapter we are using). Desktops take much more power (usually).

I hope this helps.

I went to the Black & Decker site and downloaded the pdf manual of the electromate 400. It says you're supposed to charge it until you have one red light, one yellow light, and one green light. I expect that 2 red lights and a green light means it's not fully charged. The manual also said you can't overcharge using the 120 V. method. Good luck.

First, you should be aware that the exact inverter is available for under 40 dollars all over the US. Your model is sold under several names - check out http://search.harborfreight.com/cpisearch/web/search.do?keyword=inverter .

I suspect that your INPUT power level is not adequate for the inverter to put out the 200W that the 150W charger needs. If you have low current and low voltage - then the inverter can only put out a proportionally smaller AC wattage level. You may also have a faulty voltage sensor....at the input. Once the inverter sees a low level (even momentarily), it alarms and shuts down the output until the unit is reset (turned off/back on)

change batteries, your charger should indicate wheather you battery is good or noot on the pause inbetween blinks.

From the manual:

"Attach the barrel tip of the AC Charging Adapter to the AC Charging port of the POWER TO GO® and plug the standard two-prong plug into an appropriate, functioning 120 volt AC outlet. The red Battery Status LED indicator will flash, indicating a proper connection has been made and the unit is charging. The green Battery Status LED indicators will gradually light as the charge level rises. The POWER TO GO® must be charged for approximately 11-17 hours prior to first use. All Battery Status LED indicators will be lit solid (the red indicator will stop flashing) when the unit is fully charged.
