Query: Great Long lasting product

This product has lots of power, whether used for jumping your car/truck, powering a cell phone charger, TV, lights, about almost anything. One thing I use it for is when my power goes out I take it into the basement and with the DC to AC converter built in I power my sub pump so my basement doesn't flood. Usually when the power goes out it is raining or snowing so you def. need your sub pump. Overall works great, keeps its charge a long time and you can keep it charging constanty without worrying about reducing the life of te battery. If you need more power you can also hook the jumper cables up to another battery and there you go more battery power. A++ 28aH battery with AC-DC converter, small light and AM/FM radio built in.
