I Tested And Reviewed 8 Best Inverter Generator For Power Outage (2023)

I recently purchased the Grecell 2,000 Watt Power Station (Model 2001A) and I must say, I am thoroughly impressed with its performance. After conducting various tests and experiments, I can confidently say that this power station is a top-notch product that offers great value for its price.

One of the things that stood out to me right from the start was the exceptional packaging. The product arrived in double, heavy-duty corrugated boxes that were perfectly designed to protect the unit during transit. The unit itself was surrounded by pliable foam, ensuring that it reached me in pristine condition.

One of the standout features of the Grecell Power Station is its ability to function as a complete off-grid energy package. It comes equipped with an MPPT Charge Controller and an adapter for standard solar (MC4) connectors. This is a major advantage over some of its competitors, as it allows you to use standard solar panels instead of being limited to proprietary and more expensive options. I personally purchased a standard 425-watt LG panel with MC4 connectors and it worked seamlessly with the power station. Even on partly cloudy days, I was able to run a full-size refrigerator/freezer and still see an increase in the battery state of charge. The system efficiently manages simultaneous power input and output, making it highly reliable.

Another aspect that impressed me was the quick recharge time. When connected to an AC wall power source, the power station could be fully recharged in less than two hours. After complete discharge, it took just under one hour and forty-five minutes to reach a full charge. This is a huge advantage, especially in emergency situations when the grid is down. With a full charge, the power station was able to support essential appliances like refrigerators, freezers, and furnaces for at least 12 to 14 hours. In the worst-case scenario, where a generator is required for recharging, it would only need to run for a couple of hours a day. However, on sunny days following a night without power, the need for generator usage would be significantly reduced or eliminated altogether.

One notable feature of the Grecell Power Station is its quiet cooling fans. They rarely run unless the unit is being recharged using AC wall power. This ensures a peaceful environment, even during charging.

Finally, I was initially skeptical about the total output power of 2,000 watt hours as advertised. However, after conducting several tests with different loads, I can confirm that the power station lives up to its claims. It consistently delivers the expected power output, allowing you to power multiple devices without any issues.

I am absolutely thrilled with this portable power unit that offers multiple functions. While I own two Omnicharge 20 Plus batteries, the only difference with this unit is the absence of wireless charging, which is more of a convenience than a necessity. In my opinion, this unit is superior because it provides a wide range of input and output options, along with a massive capacity. Compared to Omnicharge units, this option is significantly more affordable.

First and foremost, it is crucial to read the manual thoroughly before using this unit. The manual emphasizes the importance of charging it to full capacity initially. As someone who deals with lithium-ion cells for my hobbies, I am aware of the protocols necessary to maximize their lifespan and performance. Lithium-ion cells undergo a break-in process where their capacity increases to its fullest potential after a couple of uses. If you plan on storing these cells without utilizing them, it is recommended to maintain their charge at around 50% or 3.7 volts. However, if you intend to use this unit frequently, keeping it fully charged is advisable. For long-term storage of a year or more, depleting the unit to approximately 60% charge is recommended.

Moving on to the input and output features, this portable battery offers a wide range of options. Personally, I frequently use a TS100 portable soldering iron that runs on approximately 19 volts DC. The AC power supply I utilize with the soldering iron is compatible with this battery, as it provides 18 volts at 2 amps. Conversely, I can also power my soldering iron using this battery, as it offers up to 120 volts through the AC outlet. Additionally, the Type C power delivery socket is capable of delivering up to 45 Watts, which is incredibly useful for compatible devices.

An additional feature that I appreciate about this unit is the use of standard 5.5 by 2.1 connectors for the DC ports. These connectors serve as both output and input for charging. Other portable batteries, such as Rockpals and Jackery, often have proprietary connectors for DC charging, making it confusing and inconvenient as you are required to use their specific accessories to charge and utilize the unit. However, with this unit, standard connectors can be used, allowing for compatibility with a wide range of charging options.

I purchased this generator recently and have been using it for a few days now. The manual recommended using a 10/w30 dinosaur oil, but I used a synthetic blend with 90% dinosaur oil and 10% synthetic oil. Following the manual instructions, I added a little motorkote in the cylinder to avoid a dry start. The generator started smoothly on the first pull, although it did sputter a bit until the motorkote burned out.

I connected a floor fan and a shop light to the generator on economy mode, and there were no issues. The generator has been running continuously for several hours without any problems. I also hooked up a small fridge and freezer, and they both kicked on without any trouble. When the compressors turned on, the generator RPM increased for about 30 seconds.

I have been monitoring the fuel consumption closely. Yesterday, I added 28oz of gas, and it ran out in 2 hours on minimum load. Today, I added 56oz of gas, and it has been running for 4 and a half hours. Based on my calculations, it should run for another 30 minutes on this amount of fuel. With a half load, I estimate it could run for around 8 hours, and at 75% load, it should last about 7 and a half hours. These numbers are satisfactory for my needs, especially considering I plan to connect an additional 2500 to it.

I believe in taking good care of internal combustion engines, and with proper maintenance and care, they can last a long time. While some may opt for a $1200 Honda generator, I find it more practical to purchase three of these generators for the same price.

I make sure not to leave gas sitting in the generator as ethanol absorbs water, which can lead to carburetor issues. Once water sinks to the bottom of the carburetor bowl and turns into a crusted mess, cleaning it becomes nearly impossible. Soaking it or using a rebuild kit won't help, and it's best to avoid this situation altogether by not leaving gas in the generator.

In terms of performance, the generator has been running consistently. It did start to sputter a little after 4 and a half hours of continuous use, which suggests it may run for a little while longer on the current amount of fuel. I will be monitoring this closely.

To provide an update, I recently filled the generator with gas and connected it to the window unit A/C in my shop. It ran from 12:30 pm to 10:30 pm without any issues. I'm unsure of how much gas is left in it, but I will find out tomorrow.

Living in South Alabama during hurricane season, I have been using this generator to power my freezer, small fridge, and shop A/C.
