    My TopShak, 2200Wh capacity, arrived at my doorstep a few days later than originally predicted, but it passed my brief quality test easily. I began by connecting it to the 110 V AC to 24 V DC charger provided, and then I charged it up from 25% to 80% in 5 hours. Then I used it to power a 110 V AC 1500 W microwave oven for 2 minutes on a cup of water. It heated the water almost to boiling and so passed my quick test. Eventually I plan to use this TopShak as a virtual "AC battery" and to charge it with 24 V solar panels. It seems to me that there is an enormous amount of useful electrical energy stored i this compact device.

    Just received today. Am currently bringing it up to a full charge with the included ac charger. The charger does seem to get rather warm, Almost hot. I will update my review at a later time.
