The Undeniable ExpertPower Alpha2700 – An In-Depth Review

5.0 rating

The importance of having a backup for electrical power can never be exaggerated – not only for establishments but also for private properties.

This is often recommended, especially when a person has limited methods to stop the shortage of electrical power. 

During cases of a power outage, we, as humans, find the need for a power supply imperative.

Yet we most often lack access to a power supply to run the most essential appliances, household furnishings, and so on. Hence, the necessity of alternative means of having power.

One such source is a solar generator. In this article, we will be reviewing a lesser-known type of solar generator: The ExpertPower Alpha2700. 

The ExpertPower Alpha2700 is a large solar-powered generator rated at 2694Wh of battery capacity. The unit is capable of running multiple devices at 2000W continuously and has a peak/surge power rated at 4000W. This product is approved to CE and FCC standards.

If you prefer a brief overview, you can jump to the summary section of this post, which is located towards the bottom of this article. 

So, without any further ado, let’s get right into it!

ExpertPower Alpha2700 – Battery & InverterExpertPower Alpha2700 front view

ExpertPower Alpha2700 contains a nicely-sized 2694 watt-hour lithium-ion battery.

The ExpertPower Alpha2700 makes use of LG batteries – usually considered to be powerful and long-lasting.

That being said, you can trust the battery to power multiple devices/appliances simultaneously once the sun has gone to rest. 

The ExpertPower Alpha2700 has proven to offer usage to an extensive range of items.

Items that are commonly used with this solar generator include TVs, laptop chargers, phone chargers, CPAP machines, freezers, fridges, fans, air conditioners, and so on.

Of course, how you use these items can also play a pivotal role in determining how long this solar generator will last. Most importantly, it is portable and easy to store.

The ExpertPower Alpha2700 also contains a 2000-watt AC inverter. This is sufficient for a wide range of applications, including microwaves, washing machines, power tools, mini-fridges, window AC units, and a variety of others.

As long as the power consumption from the appliance is less than 2000W, the battery in the generator will be able to continuously run.

In addition, a 2000W inverter is hard to come by in solar generators of this size. This means that the Alpha2700 can run more power-hungry devices/electronics/appliances than others in the same class of generators.

Some solar generators use modified sine wave technology because it’s usually cheaper to produce at the manufacturing level. However, the Alpha2700 uses a pure sine wave inverter and allows the solar generator to run all household items normally.

The inverter and the battery are high-quality products in themselves. With these factors in place, you may be wondering if the quality of the generator reflects in its pricing.

In terms of price, the ExpertPower Alpha2700 is expensive but is at a lower price point when compared to other solar generators of similar size. 

Finally, you should also know that the peak power offered by the ExpertPower Alpha2700 inverter is 4000W. Note that running this amount of power will only last you (on average) a couple of minutes at best due to the battery overheating. This is standard with solar generators, as the peak (or surge) capacity is not meant for extended use.

Solar Input

The second criterion we will be basing our review on is the solar input of the device. 

Overall, the ExpertPower Alpha2700 offers up to 720W(36V/20A) of solar panels for charging. And, of course, this is great! Why? Let’s break that down…

With 720 watts from the panels coupled with a battery of 2694 watt-hours, under ideal conditions, such solar panels can charge the battery from zero to fully-charged in a matter of about five hours.

And, coupled with the battery, you can be sure of having a fully charged ExpertPower Alpha2700 while still running important household items such as freezer, fridge, computer, and whatever other items that you choose to power.

ExpertPower Alpha2700 battery applications


Another essential criterion to rate the Alpha2700 is its lifecycle.

This solar generator is rated to 1000+ cycles. This implies that if you make use of your ExpertPower Alpha2700 daily and properly charge and discharge it, you will be able to do so a thousand times before the battery starts losing its capacity. This does not mean that the battery is dead, it means that the battery will not be as efficient as it was for the first 1000 cycles. So you can still use it for a longer duration after the 1000 cycles if you wish. You can prolong the life of your battery by making sure to take care of it and use it properly.

ExpertPower Alpha2700 specifications

Battery Discharge

Inarguably, a better percentage of users of solar generators do not have a full understanding of important parameters and elements, such as volts, watts, amps, solar, loads, and so on. And, to this end, we have seen several companies exploit this to their advantages. Honestly, this is not right and should be discouraged.  

Basically, the ExpertPower Alpha2700 has a 2694 watt-hour battery, plus a 2000-watt inverter. The combination of these two can make use of 2000 watts before the battery goes dead. The rate at which you are pulling power from a battery is called the discharge rate. It is essential to know this due to certain reasons that will be explained in the following paragraphs: 

For instance, the Inergy Apex features a 1500-watt inverter, plus an 1100 watt-hour battery. However, the continuous discharge rate of such a battery is just 550 watts. This means that it can run on 550W for about two hours before the battery is used up completely. However, if you pull anything above 550W, this dramatically reduces the battery life for that one charge. In a video demonstration from Will Prowse, he runs the Inergy Apex battery at about 1,300 watts for just over three minutes before the battery shuts off due to overheating. In essence, this means that if you were to use more than 550W of power on this generator, the battery would only be able to work for a limited period of time before it overheats and shuts off.

This is an example of a solar generator that does not make use of batteries that are entirely compatible with its inverter – i.e., the inverter is operationally larger than the battery. And, when this happens, it results in a situation whereby the battery cannot run continuously at the inverter wattage that the inverter is rated at. 

Several companies understand that most consumers do not know this, and, therefore, make use of it to their advantage. It is all shades of wrong, nonetheless, and more often than not, eventually results in buyers’ remorse. 

Evidently, from analysis and reviews, we can safely say that the ExpertPower Alpha2700 is not caught in this web. Their battery is the exact “better half” of the inverter designed with it. This translates that, with the ExpertPower Alpha2700, you do not find yourself paying for a feature you can’t or won’t use to its entirety.

Powering Up

As a new user of an ExpertPower Alpha2700, you may find it tricky to power up at first. Just pressing the power button does not actually power up the solar generator. Instead, you need to hold the button down for approximately two to three seconds to get it started.

The ExpertPower Alpha2700 is designed with three buttons located at the front. These buttons are the DC Power, AC Power, and Power buttons. The LCD display shows your battery status, screen info, and input power.

However, another thing to note is that holding down the power button to start the generator does not translate that power will flow into the plugs. Instead, if you want to power the plugs, you need to consider them individually. That is, for the DC plugs, you hold down the DC power button for about two to three seconds. The same applies to the AC plugs.

Don’t worry, in case you are confused. We trust that this will be more explanatory when you have the product in front of you.

Car Charging

The ExpertPower Alpha2700 doesn’t have a car charger. We can assuredly say that this is the biggest downside of this solar generator. For instance, its portability infers that it is mobile, and can, therefore, be transferred conveniently from one point to another, regardless of the distance.

Now, should you find yourself on a camping trip, you may find it impossible to top off your solar generator unit before arriving at your location. This may appear insignificant until you find yourself in such a situation where you need the extra power. 

Nevertheless, there are ways to get around this. One of the simplest means is buying a car DC inverter. With a car DC inverter, all you need to do is to plug the wall outlet into it. As much as this is an easy solution, it is still saddening that the ExpertPower Alpha2700 can’t be charged normally from a car.

Plugs and Ports

Next are plus and ports. For this product, the plugs and ports used are quite simple. Generally, the ports and plugs included in this solar generator are:

  • 110/120v AC plugs at the back
  • Four 5V USB ports
  • One USB-C 45W port
  • One DC cigarette lighter style port

The charging port is rated at 10amps and 60volts. 

However, as nice as the included ports may appear to be, we think it would have been better if two or more 110/120v AC ports were added. We say this because, over time, we have discovered that most people do not make use of USB per se and would prefer more AC plugs.

Also, you will notice that the ExpertPower Alpha2700 does not have a 30amp RV plug. And this is too bad, as the availability of this plug inarguably makes it a valuable solution for the RV community.

ExpertPower Alpha2700 dimensions

Weight and Size

Again, the weight and size of this product are consequential to its usage and, therefore, demands to be analyzed, too.

As much as the Alpha2700 is portable, you may be surprised to find that it is quite hefty for some people. The unit weighs 59.5lbs, which is obviously a significant heft for most people. However, it is fairly light compared to solar generators of similar size. For example, the Yeti 3000 Lithium has a slightly larger battery and weighs about 77lbs with its roll cart. 

The ExpertPower Alpha2700 weighs 59.5lbs. With its roll cart, it has a height of 20.5”, is 10” wide, and 12” long.

Rating: 7/10

Shelf Life

The ExpertPower Alpha2700  should be used and charged about every three months. However, even when not used, but left at 100%, you can be sure of it meeting your requirements. It will remain in excellent condition and maintain close to a full battery as you have left it. So, considering all these, it is safe to say that the ExpertPower Alpha2700 has a long shelf life due to its lithium battery.

Rating: 8.5/10


Finally, the last criteria for which we will be reviewing the ExpertPower Alpha2700 is its warranty. The  Alpha2700 comes with a one-year manufacturer’s warranty. And, logically, this is nice and reasonable. At least this allows enough time to ensure that users make use of the device all-year-round – subjecting it to different conditions.
