The product itself is absolutely pretty amazing actually the only downfall is something's make the battery die much faster than other things but a full charge last up to 18 hours depending on what you was in it for I actually plugged in a battery charger and then hook the battery charger to to congruent batteries when I'm positive when a negative and it literally ran my entire camper for 12 hours I haven't really got to try it with the solar panels just yet but it is pretty portable it's very heavy especially for me though cuz I'm disabled but it's very handy you can plug it into your car to charge you can plug it in the wall to charge you can put solar panels up in charge it and you can use it for so many different things there's actually I believe a 210 plug there's like four 110s there's several USB Outlets and I believe you can buy a adapter to charge your car battery with it like to start your cars it's pretty neat in the way it hooks up to your phone you can control it from your phone it's pretty cool as long as it has Wi-Fi and Bluetooth connection it is a really good thing to have when you're trying to live off grid or if you camp a lot if you have a lot of ATVs or boating really nice to have
