Note also it stores 270 watt hours of energy. A 270 watt hour battery would cost you about $54 and you can recharge it thousands of times. The hydropak costs you $20 for each 270 watt hours delivered to load. Or $74 per kWh. I can charge my battery for $0.07 per kWh. That is a factor of 1000 times more for the cost of the energy.
