We did research for a portable power station and are comfortable with our decision. The customer service is excellent and informed the shipment status well. Their emails are in a very polite manner. We just received the unit, so not ready to review its performance, but so far, we are happy with the solar panels' light weight and the design. The unit is heavy, but the size is compact enough, and the built-in carrier is convenient. But it IS too heavy for a woman in 50s to lift. Since we live in NH, solar charging is not exactly the most efficient, and we did not anticipate the unit to charge quickly like it would do in the south/ south west. We are in fall now, and it took us 2 full days (the total sun exposure was about 12 hours) to charge the unit to 100%. We hope it will be better in summer. The best feature of this unit we think is the fact that it can recharge and discharge at the same time. We are hopeful it will perform well, but I intend to write another review when we test the unit for some appliances.
