I ordered this as a backup of my regular power generator which can not be used in some campground in the night time. Besides the weight, this unit provide me all of the needed function. I am deeply satisfy with its performances. As a sponsor of this project, I also like to make some suggestions as following:1) consider to increase the amperage of 12 volt output. (Some 12 volt tire pressure pump needs more power to run);2) add a negative to ground switch for special events. (My Nissan Leaf electric car charger can not directly use this unit because it’s ground wire design, using a home made plug which connected ground to negative to one of four outlet won’t solve this problem since the other three outlets still considered as not properly grounded; u have to use a multiple outlet strip and plug my home made plug to overcome this problem so I can use these 2 KW to charge my electric car for emergency situation;3) when some other brand starts to add connection plug-wire to their unit so the user can add extra batteries for more power output (such as 1.5 KW extra batteries pack can piggy-back to their original 1.5 Kw unit and make it to 3 kw system), our unit should have similar capacity to do so.Overall, I am very please the performance of this unit.
