SUNGZU 1000 Watt Portable Power Station Solar Generator 1000W(Peak 2000W) /1010Wh for Camping Home Outdoors CPAP Lithium Battery Solar Powered Generator with 2 110V AC Outlet 2 DC 4 USB

I purchased this sungzu 1000W solar generator back in mid September (2019) to be used in my minivan to power a small 1.7 CU,FT mini fridge. I have a job where i drive my personal vehicle between different stops, that can mean I'm out for up to 8hrs a day. Its nice to be able to keep food cold while out working, especially since my job is based around going to different grocery stores. I can buy what is on sale and not need to worry about how long I will be out for. I do plug into shore power when I'm at home but the fridge won't stay cold for a full 8hr day, specifically in the summer. I also have a small camper setup in the van for when I want to enjoy some time in nature, or the parking lot of the big "w" store. Lol! That means at times i have some additional power needs as well. In addition to the fridge i also have a 19" RCA TV, a standard LED lightbulb, a ROKU, and many chargers for phones, iPad, ect. When I'm out working i only plug in the refrigerator. However I did connect the main power plug to the sungzu and it handled it just fine. My fridge started right up, the TV and ROKU came on and all my other various small devices came on with no issue. I only let this run for about 5 minutes because this was just a test. I have not gone camping with this battery yet because it has been cold in my state. I will definitely update this review when i have a chance to use this battery while van camping. In fact, the way I've been using this battery I have not even drained it past 80% full. A full workday for me with the fridge plugged in all day, cycling on one off, does not even use 20% of this battery. (ambient temp outside 25*F- 55*F with heat on while driving.) As far as the DC output, I have only used it once with a small 12V air compressor to inflate my tires and it worked fine. The USB ports on the other hand, they work, but are not high powered. My iPad Pro 10.5 still drained while watching youtube with low brightness while plugged into the USB port. So for USB charging i'd recommend either plugging your device in with the AC adapter or using a DC car charger. The sungzu was delivered with about 40% charge and charged rather quickly (within the afternoon) from the included AC wall charger. I can't give an opinion on the solar performance because I only charge with the AC wall charger. Overall this is a well priced and high capacity power station. I personally was debating between the sungzu 1000W solar generator (1000 Wh battery 1000W inverter), the Maxoak Bluetti (1500Wh battery 1000W inverter), and the inergy apex (1100Wh battery 1500W inverter). Out of the three only the inergy apex will power a microwave or induction plate and none are recommended for a space heater. For my use this is perfect! It will run my refrigerator all day while i work and will power the rest of my camper van whenever i decide to have some fun. My only gripes with this power station are that the USB ports are underpowered, the status indicator is a 5 bar battery symbol, not an exact percentage, and the charging input is non-standard, limiting you to the sungzu wall charger and solar panels or forcing you to risk shorting something out by making your own connection. If you want the most capacity, go with the Bluetti, if you want the biggest inverter or expandability, go with the inegry apex, if you are a bit more budget conscious and are primarily going to be charging from the wall, not solar, than go with the sungzu.Also, because it has gotten colder in recent weeks I have been storing and charging this power station in the house. It is not recommended to store, use, or charged most lithium based solar generators in temperatures below 32*F. I will also likely be storing/ charging this power station in the house during the heat of summer also. It is not recommended to store most lithium based solar generators In extreme heat or cold unless actively being used at that very moment.EDIT Immediately after clicking post i looked for a 4pin to MC4 adapter (specifically i searched "sungzu input adapter") and found that sungzu themselves are selling them here on amazon and instantly ordered one just to have. So at this point i can fully recommend the sungzu to anyone looking for something of this spec to use with solar. :) I will probably order a solar panel in the spring now that I will have the ability to use any one I choose. There is still no good option if something happens to the wall charger though. Not even sungzu sells a stand alone AC wall charger, not even an over priced one.(Update 1, 5/14/20)The sungzu solar generator has been holding up well. I have been mostly using it for the fridge exclusively. (It has been a cold winter in my state, so not great camping weather.) I have still only managed to drain it to 60% (between 60% and 40%. There is no true way to tell because of the 5 segment charge indicator). I went on an overnight trip to a hotel. I used the fridge to keep food cold during drive, I shut down the battery, and in turn the fridge, after I got to the hotel and took the food out. The next morning, after checkout, I loaded up the fridge with food and powered it up for the drive home. The fridge was on about 12-14 hours between the two days and only drained the battery to 60% full. A typical work day will only drain the battery to about 80% full and sometimes won’t even drain enough to drop the charge indicator.( between 6-8.5 hours of the fridge cycling on and off with outside temperature being the obvious variable) I have also used it to power various small devices throughout the winter and it met all my needs. The most demanding thing I plugged into it, other than the fridge, was a rotary tool. It probably only draws a few hundred watts. As for solar, I had bought the MC4 adapter with intentions of buying 1 or 2 100W solar panels to charge up the sungzu in the event of a power outage or extended dry camping in the van. I personally have not been able to find a combination of solar panels, or a single residential panel (higher voltage) that meets the input voltage of this solar generator. It is either a few volts under or over the rated 32 - 45 volts. Because of this I am thinking about just buying the solar panel made by Sungzu, however that panel has mixed reviews with one user even saying that it “has trouble with absorption” which is not even the right terminology for a lithium battery but translates to it will have a hard time past 80% state of charge. That same reviewer also stated that the panel only reached 29.9V which is barely enough to turn on the charge controller. This has made me rethink the choice of purchasing the Sungzu ska 1000 over the maxoak bluetti. It is fine for the way I primarily use it, which is like a power bank, not a solar system. I charge it on shore power, use it through the day as I drive, then connect back to shore power at night when I park. I will be installing an inverter in the van, connected to the starting battery and alternator to be able to recharge the Sungzu while the van is running if I need to, mostly for camping or long road trip purposes. If you intend to charge this off of an inverter, be aware that the wall charger draws about 450W from the wall, so I would recommend a properly installed 700W or higher inverter to charge the Sungzu off of a running vehicle. At this point I most likely will hold off on solar until I purchase a different solar generator. Even if I do end up buying a different solar generator for the van I will definitely keep the Sungzu as a backup for home use in the event of a power outage. My original opinion still stands. If you are going to use this device as a power bank that is recharged on shore power or by a gas generator the Sungzu is a good option. The fast AC wall charger will even be beneficial to generator users because you won’t have to run your generator as long and will burn less fuel. If you want something to reliably use on solar for extended periods of time I’d still recommend the maxoak bluetti, either size, or the ecoflow delta. The inergy Kodiak and apex have both been discontinued and there is a new product called the inegry flex that will be coming to market at some point.Just to be clear on exactly how I use this product. When I connect to shore power I also connect the fridge directly to shore power. I turn off the inverter output and I only charge the Sungzu until it reaches 100%. After it is fully charged I disconnect the Sungzu charger and leave the fridge on shore power until I need the battery again. I do not let the fridge run through the Sungzu battery plugged into shore power.

Overall, this is a good solar generator. I will go over the pros and cons.Pros:Portable- This by no means is super light, but it is light enough to be portable. Other solar generators out there are super heavy.Durable- I’m not sure what material they use on the outside casing, but it is high quality. This device is built to handle the outside use (setting it down on the ground, ect). It even has rubber on the edges which doesn’t seem like a big deal at first, but it is just incase if you are caring it into your car, or something lie this, if it hits something the rubber will protect the device and car. There are covering on the outlets which is nice.Potentially a regulated DC 12v- I didn’t test this with a wattage meter, but I used a 12v electric blanket in a camping situation and even when the solar generator was at 20% the 12v electric blanket still worked and still put out plenty of heat. Again, not an actual test, but I believe their 12v input is regulated. This means, when the power gets low in the solar generator, the voltage out put doesn't get low, which will make it where a person will not be able to run 12v devices while the battery is at a low charge, if it did this, this would be unregulated.Accessible fuses- This is a BIG DEAL. If you were to blow a fuse, Sungzu allows you to replace the refuse. They even include 4 extra fuses. This is a big deal because other companies have built in fuses that are hard to get to and you may void your warranty if opening up the device. Because of this, if you blow a fuse with other companies, you’ll have to ship it back to them to get it fixed. Sungzu was brilliant in having easy access to fuses just in case a fuse blow.Super Charger- Yes, that’s right, they have included a power brick super charger. They really don’t advertise this that well but for me this was a big deal when using this device. The power prick AC to DC adapter charger is 240 watts an hour!!! And the power brick has its own COOLING FAN!!! This is genius! The power brick never got hot when in use. Sungzu is very modest when saying that it will take 5.5-7 hours to charge. It takes me under 5 hours to charge the device by wall outlet. So good job Sungzu with this! I wish other companies would follow suit, who wants a toasty power brick while charging their device?MPPT Charge controller- They truly have a MPPT charge controller built in. With two 50w panels connected in series, I was able to get 75 watts at solar noon. This is above average when compared to other companies that are well known. Some well-known companies don’t even have a MPPT charge controller, which will make for slow charge times when using solar.Cooling fan- Fan is pretty quiet. It turns on with the power brick while it is charging, it’ll turn on to manage temperature if in a hot condition. It’ll turn on if you reach a certain wattage on the DC or AC outlets.Display- They display the temperature!! Like, this is a big deal! Why don’t other companies do this?! You need to know what temperature your lithium battery is at to prevent damage. Thankfully Sungzu has built in safety features to cool down the battery if in hot conditions with their cooling fan. I’m not sure if they have cold protection which will shut down the unit of the battery gets too cold. Lithium batteries must operate in a certain temperature setting or it could be damaged. Having the displayed temperature of the battery something that all solar generator companies should be doing. Sungzu sets the bar high.Amazing customer service- This is not joke. Sungzu will answer same day when sending them a email. They were very good at communicating and answering any questions. Honestly, there are many solar generator companies out there, that are no name companies and I was afraid to try out Sungzu, but in all reality they are a reputable company that has been manufacturing solar generators for years18 month warranty and 30 day returns- This shows how confident they are in their product. Other well-known companies will only offer a 12 month warranty. Why is that? Sungzu stands behind their product and offers an 18 month warranty and a 30 day return period.Cons:May not be pure sine wave- I didn’t have a sine wave measurement device, but I did do a poor man’s sine wave test by using a regular household box fan on high settings while plugged up to a regular house AC wall outlet and then I plugged up the fan to the solar generator. When plugged up to the solar generator on high settings, the fan blades did not spin as fast as it did when plugged up to a regular household wall outlet on high settings. Pure sine solar generators would have produced the same fan speed from my wall outlet. The household fan was rated for only 160 watts. Again, Not an actual scientific test, but I believe the AC output for the solar generator is not pure sine wave. But the AC outlets still work very well. I hooked up my TV to the AC outlet and it powered it up fine, and it could charge my portable devices by AC fine. At this affordable price point, I think the AC outlets on the device work good enough.Display- I wish it would display how much watts is being used and how much watts is being input into the battery. Quiet honestly, I don’t care about the voltage at all. I want to know how much wattage I am getting each hour. I hope in the future, they change the voltage meter to a wattage meter. To know how much watts you are producing via solar you have to buy a watt meter. They have a MC4 watt meter on amazon, and Sungzu sells a MC4 adapter.MPPT charge controller- 75watts out of 100 watts is good, and when compared to other well known solar generator companies, it is above average. But there are MPPT controllers out there that can push 85 watts or more from solar panels that equal 100watts. But at this price point, I think this is good. But if you are really depending on solar energy, you may have to spend a little extra and build a custom solar station or buy a more expensive brand with a better MPPT controller so you can get the most out of your panels. For reference, I was using two 50 watt panels in series with Sun Power solar cells.32v minimum- This was one of the frustrating parts about this solar generator. You are required to have at least 32v minimum of input. In reality you can get away with 29 volts. So is there any solar panels out there that output 32v minimum? Yes, one I found on amazon, Sunzu’s 100 watt panel. If you are not going to use their panel, then you will have to find at least 18v panels and hook them up in series to get 36v. The battery management system (BMS) will down voltage and manage the amperature of the panels to protect the solar generator, so you will be around 30 to 31 volts on a good day. But having such a high requirement of voltage input does make it mandatory to where you have to buy at least 2 solar panels that are not the standard 12v output, but has to be higher than that, and the next tier I could find on amazon is 18v panels. Sungzu sells a MC4 adapter so you can connect the solar generator to MC4 compatible solar panels.Overall this is a great solar generator. I hope my review helps someone!

Fuse panel cover only stays in place when fuses are not installed. Fan is loud.
