Price and quality are awesome, glad I purchased. For convenience, I keep it on my side table for easy access to charge-up my cell phone, earbuds, tablet, etc. I did notice the usb charging is fast. You won't be disappointed.

Convenient and works great; spaced out enough to use all ports, and charging is better than expected.

This was listed as a 6Ah battery for Milwaukee tools, but what I received was one labeled as "9.0Ah output". I have had Milwaukee tools for many years, but have never tried an off brand battery like this one. The size of it is like that of the newer 8.0Ah High Output batteries. I DO have an older style 9.0Ah OEM Milwaukee, so I tried comparing it to that. First of all, it is shorter and more squat, as mentioned, but it also weighs about 4oz less too. Interesting. I expected that there would be a break in time to get the battery up to full capacity the first few uses, and I hope that is the case. I have done 2 full charge/discharges with it, coupled with doing the same thing with my old 9Ah. I spent a lot of time cutting weeds with the string trimmer and it didn't last as long as my old 9. I have also used it on my 6.5" circular saw and, again, didn't think it lasted as long as my 9. Here is my opinion. I don't know what IS in the battery, but it felt to me like it almost had the power of a High Output Milwaukee, but the lasting power was closer to that of a 5Ah. With the string trimmer, it seemed to be just a little less powerful, I think, but it didn't die as soon as a 5.0 would have. Sure felt like it lost some power at the end instead of holding pretty steady then just stopping. ALL OF THIS might be because it is new and only been cycled a few times, but the lighter weight, inaccurate listing and such makes me wonder. That said, it was like $50, so that compensates for a lot in my opinion. At this price, I would recommend giving it a try and take the chance like I did. Time will tell how long it lasts, but I just had a OEM 8Ah die on me in less than a year at twice the price, so perhaps it's all a gamble.

More and more items I am purchasing are just coming with a USB cord. This is very useful for having multiple different cords.

This was specifically purchased for cruise trip. For this purpose, it is absolutely perfect. It does not have surge protection, which is a no-no for the ship. Otherwise they will confiscate. It is small/compact.
