ROCKPALS Power Station 1000W

First off, I do NOT recommend anyone buy Rockpals... I bought this unit end of last year from Amazon. Didnt get a chance to use it until this last month, so anything mentioned below that could have been solved by sending it back to Amazon is not possible and it is my fault, especially if I ended up with a klunker unit and maybe this is not typical results, but there are my results as they could be your results as well. 1. This unit says it has 1048 Watt Hours, I have yet to get more than 750wh Capacity using a 100 watt device and let it go with a timer to find out the total hours available with this unit is nearly always 7 and a half hours regardless (6 hours 55 minutes for AC, vs DC is 7 hours 35-40 minutes) using 100 watts with my kilowatt device because the screen on this unit wont tell you anything. that's the next issue.. the screen is USELESS 2. The display does not give you any actual useable information. Here is what I mean, it just says what is turned on. It doesnt even tell you if anything turned on is actually being used. Like it will say AC and DC or USB and that's it, on an LCD screen, like graphics display.. as if you need this. Not sure why there is a screen at all.. this Info is no different than a RED LED Light next to USB or AC.. etc on or off for those things. So the screen power usage is a waste. 3. When you have something plugged in if the power draw drops down far enough the unit will randomly decide to turn it self off, which you might think is a good thing, but not always.. for example with USB, I would want to set my phone on the wireless pad plugged into a USB port, turn on USB, and after 100% full charge on the phone the wireless pad will go dormant for 30 minutes or an hour and then try to come back to see if it needs to top off the phone again, but this battery unit is now shut off and will not come back on unless someone manually presses a button somewhere. 4. The Solar Charge Port on the front is a typical Anderson small 10 amp, fits my Solar panels just fine. I have two panels, tried in parallel for higher current which according to my volt meter hits 20volts if there is any sunlight in view.. this is problem with this unit as it REQUIRES more than 24 volts to charge using Solar.. but there is no label for that... typical Anderson port your thinking I plug my panel directly there because there is no charge controler or MPPT involved and those are almost always 12volt.. not 24 or 36 unless there is a charge controller involved. even with these two 100 watt renegy panels in series it will NOT charge, and it's like it DRAINS the batteries to have it connected to 200 watts of Solar. Left it plugged into these two panels for an entire day full sun and come back and find I only have 2 bars out of 6 when I started with 4 bars. Then when you take it in the house and plug it in and its like it starts all over with a totally dead battery and takes another 24 hours to charge back up. This makes no sense when I started with 4 bars, charged in solar for 8 hours, now with 2 bars and plug it into the wall with its included Brick and it just blinks and charges for a full day to get it back above 4 bars. Not sure where the power went? into the solar panel or just went up in invisible smoke? 5. When you plug something into this unit which is more than 500ish watts, it Immediately Blinks out and shuts off, no reset, no nothing, to get it back on is manual press and hold a tiny button. The design is like they jammed a bunch of 18650 batteries in here, looped them together in a couple of 12 gauge 10amp wires and stated total power based on if all those 18650s where pushing full power, but did not really plan much for current and efficiency "through" all of those. I have a tiny 600 watt (killowat tells me the max watt usage of this guy is at 612watts) ceramic heater that sits under my desk. When I plug that in this unit resets within 2 seconds, same with my 800 watt microwave or my 800 watt mini fridge. Either I got a Klunker or this unit is JUNK. If I did get a Klunker, I will not try to ship this 100lb thing to someplace in the hopes of getting it fixed and based on other reviews RockPals likely will not send me a shipping label.. so now its a giant door weight that can power sub 500 watt Stuff like a router, laptop, cell phone charger, or desk lamp. 6. Picking this thing up and moving it around is really tough. Im 6.2' 220 and above average build at least in my area.. and although I can pick up this unit with one hand it's just barely and you wont go very far with it this way. Grab with Two hands pull to your chest and you can carry it out to the yard or to get it into your vehicle, but you wont be carrying anything else at the same time, or going very far at all. as it is Very heavy. feels like its filled with Concrete and not Lithium... deinfately NOT lithium Phosphate.
