Battery is exactly as described. It lasts about 30 to 40 minutes with semi-constant use. It also recharges quickly with the rapid charger. I have not had it that long, so I cannot say if it will continue to hold a full charge or not.
The inverter will serve the purpose/convenieince of charging devices and powering a simple table fan at our farmer's market booth. Perhaps this will supply a bit more power than would be necessary for a simple fan & charging devices while at a remote location yet this inverter would be not much use re: power outage of home as it only supplies 300 watts and will not power a small appliance such as an electric tea kettle or fry pan, (which would be useful during a power outage) and much higher wattage demands.

Hello GWuser,
Thank you for taking the time to share your experience with this product. We are concerned to read that you are feeling let down and that the unit has not fully met your expectations. As this is a 300W inverter, it is ideal for powering small items such as televisions, lights, fans, speakers, coffee makers, small appliances, laptops, tablets, cell phones, headphones, and more! The electrical requirements vary between items; it is important to know what the equipment requires. Here are a few important facts to keep in mind with this inverter. 1) This product outputs a modified sine wave (filtered). In a pure sine wave inverter, the polarity switches smoothly, with gentle curves. With a modified sine wave the polarity change is abrupt. This type of waveform is suitable for most AC loads, including linear and switching power supplies used in electronic equipment, transformers, and motors but there are some exceptions. 2) This is only a 300W inverter. To calculate what your equipment requires, have a look at the manual, plug, or tag. There should be the volt and amp rating. Multiply these figures to determine the number of Watts the product requires before attempting to use it with an inverter. For further troubleshooting and assistance, please contact Greenworks Pro toll-free helpline at 1-855-345-3934. We are always happy to help.
I bought one of these when I bought my mower a year ago. Just bought another on this year. I like to mulch and it takes two of the extended batteries to get the whole yard done
This big honker more than doubles the run time on both my regular chainsaw and pole saw. It's exactly what you expect. It's big, heavy, about 1.5 times the length of the 2ah battery. Charges really fast! 30-40 minutes for a full charge. Very happy with the performance.

I so far only own the lawn mower tool, more in the future. I have two batteries a 4 and a 2 and as 80v batteries they are pretty physically large. I got the inverter for power outages and to charge my phone in an outage, haven't needed it so far but knowing it's available is comforting. I wasn't thinking about powering my laptop or tablets but 300 watts will power my Asus Rog 14" gaming laptop and my samsung tablets easily. Best case scenario you want a pure sine wave inverter for a computer but when you're in the situation you use what you have at hand for sure. You may run into a few picky power supplies that will not work with it on very high draw, high spec gaming laptops all you can do is try it. People have also asked about items such as cpap medical equipment, it "should" also run those however those items are also electronic and have internal computers so I would run those items on this with caution as this is not a pure sign wave unit (using the original power supply for the item should help smooth out any irregularities in the AC being supplied).
