Solar generators have become convenient energy solutions for outdoor power requirements in recent years. These portable devices can be used anywhere to provide off-grid power instantly. You can charge all of your electric devices including cell phones, cameras, flashlights, laptops, drones, and other outdoor electronics. Their energy generation capacity is only limited by the strength of the inverter integrated into these generators.

Jackery is the industry leader in manufacturing high-quality solar products. Jackery power stations are very popular among a wide range of users. One of their entry-level products is the pure sine wave Jackery 240 Solar Generator. Even though it is an entry-level product, it doesn’t fail to impress you. In this article, we have reviewed the features that this product has to offer. If you are new to solar generators or haven’t bought one before, this guide is going to provide you with all the essential information on these devices.

Features of Jackery 240 Power System

Following is the list of some key features offered by Jackery 240. Let’s take a look and find out if it really is one of the best products currently listed on the market.


An inverter is an integral element of any solar station. It converts solar energy (DC) into electrical energy (AC). The efficiency of this energy conversion depends upon the strength of the inverter. Remember that a solar generator can work without an inverter. This is because you can charge it using an AC wall outlet as well.

The Jackery 240 solar power system is equipped with a 200W pure sine wave inverter with a surge capacity of 400W. This range indicates that this product is primarily built for charging small appliances such as mobile phones, laptops, flashlights, etc. Here, we must mention that solar power systems should be matched against their energy requirement before their purchase. “More is better” is not necessarily true in this case. If you are looking to power up the above-mentioned electronics, Jackery 240 is just the right product for you.

To run this inverter at its optimum capacity, you’ll need a highly efficient solar panel with at least 60W capacity. This wattage is to ensure that the panel produces enough power to be converted and transmitted by the inverter. Any solar panel with a lower capacity will slow down the entire charging process. You have to keep in mind that not all of the solar energy is stored in the battery. The inverter will consume some power for its operation as well. Therefore, you have to investigate the capacity of the solar panel accordingly.


The battery is the most essential element in a power station. Without a battery, a solar generator will literally hold no value. The power generated by the inverter is stored in a battery allowing you to carry it anywhere and attain an AC output to charge your electrical devices without the need of being around a mains supply. This is why most of the high-end manufacturers provide a lithium-ion battery pack along with their solar generators.

Jackery Explorer 240 portable power station has a built-in 240Wh lithium-ion battery. It is roughly equal to 67000 mAh which is an extensive capacity for simultaneous charging of multiple devices. Jackery uses lithium-ion batteries in these systems because they have an incredible power-to-weight ratio. These battery types are highly efficient at storing and transmitting constant levels of energy. Also, these are safe and user-friendly posing no threat of any electrical malfunction.

An AC wall outlet will fully charge these batteries in 7 hours while a 12V car adaptor will take nearly 6.5 hours. Jackery SolarSaga 60W Solar Panel is sold separately with the Jackery Explorer 240 solar system, thus making it a complete power station package. This solar panel can fully charge the battery pack in 7 hours. This showcases the operational effectiveness of all three components – the battery, the inverter, and the solar panel.

Let’s take a quick look at the estimated recharge cycles for a few products using Jackery 240. The recharging time varies in different products. Following devices have been tested to verify the performance of the battery pack.

  • Drone 60W: 4 Recharges
  • Electric Blanket 55W: 4 Hours
  • Laptop (Macbook Pro 13): 3.5 Recharges
  • Fan 15W: 15 Hours
  • Camera 10W: 11 Recharges
  • Phone (iPhone 8): 24 Recharges
  • TV 60W: 3 Hours
  • Light 5W: 40 Hours

Fast Charging

The performance of any device with a battery is measured by its ability to charge fast. In the case of a high-quality solar power station, it should not only charge other devices quickly but also its built-in battery.

Not all devices have similar fast charging standards, and therefore, different wattages of currents are required. In the case of the Jackery Explorer 240 power station, you will get fast charging from the AC port at a general rate of 200W and a surge capacity of 400W. It will consistently provide this wattage of current regardless of the receiving capacity. This means that the charge controller in the receiving devices and their charging adaptors will regulate the required wattage of current for fast charging.

Connections and Outlets

Most manufacturers in the solar generator segment differentiate their products by integrating features that improve their user experience. One such feature is the availability of multiple connections and outlets. A diverse range of input and output ports are available in solar generators that allow you to connect them with many electric devices.

This Jackery solar generator is equipped with one 110V AC adapter port, 2 USB Type-A ports, and a DC car charging port. These variable port types allow you to connect a wide variety of electrical devices while transmitting consistent currents. As this is an entry-level product with minimum power applications, Jackery has refrained from integrating additional ports. This product is designed according to its utilization and, therefore, has all the basic outlets to let you charge your small-sized electric appliances, rather than being designed to power your home, or larger appliances like the refrigerator, or even air conditioner.

Wall and Car Charging

As we have earlier discussed, these devices can be charged through both AC and DC currents. This feature relates to the recharging of a solar generator through an AC outlet as well as solar panels. Wall and car chargers are used as alternatives if you don’t have access to sunlight for a solar charge. You can quickly charge your portable power station through a conventional AC outlet.

Jackery Explorer 240 can be charged with both an AC outlet and car charger at effective speeds. Using the wall outlet for recharging will take 7 hours and the car outlet will take 6.5 hours. However, it is advisable to use these options only if you have no access to direct sunlight. For instance, you can charge your portable power station through a car charger while you are traveling. But regularly charging it through a car charger will cost you a lot of money and therefore is not economical.

Weight and Dimensions

Portability is another feature is solar generators that you cannot overlook. Most users prefer small, compact, and lightweight power stations so they can easily carry them anywhere. Providing high power in a small size is a challenging task for most manufacturers. Therefore, this feature can be one of the primary differentiating factors between high and low-quality solar systems.

The Jackery Explorer 240 portable power station weighs only 6.6lbs while its dimensions are 9.05 x 5.24 x 7.87 inches. This small size and light weight allow you to stow it even in small spaces, like the top of your car dashboard, quite effortlessly. A solid handle is built into the design of this generator for a reliable grip.


A warranty is provided to safeguard your investments. Popular brands provide warranty to build trust and offer their after-sale services. It is a feature that is highly valued by a lot of customers. In the case of power stations, a warranty is critical as these devices, just like their solar panels, are expected to have a life span of 25-30 years.

Jackery Explorer 240 portable power station comes with a 24-month warranty. Jackery ensures that all of its customers experience the highest quality of customer service. The entire process of claiming a warranty on this product is smooth and convenient. However, we suggest that if you find any discrepancy in your product, avoid performing the repairs right away. You should contact the supplier first to ensure that you can claim your warranty without any dispute.


Expandability refers to testing a power station beyond its limitations. For instance, a turbo boost is needed if you are looking to attain a higher level of energy output for heavy-duty electronics. The expandability feature will thus increase the usage capacity of solar power stations. However, these features are incredibly rare and only found in high-end generators.

Jackery 240’s inverter does come with a surge capacity of 400W over the general capacity of 200W. Apart from this, you won’t get any more expandability features in this product. The reason for limited expandability is that it is a low-powered entry-level product catering to small-sized gadgets. It would make no sense to test it against heavy-duty electric appliances such as microwaves, fridges, and air conditioners.


X-factors are additional perks and features through which the manufacturers improve the quality, performance, and user experience of their products. You’ll find more unique features in high-end solar generators as you move up the price ladder. Jackery 240 power system, though not high-end, is coupled with some X-factors. These are mentioned below:

MPPT Controller

A built-in MPPT controller is integrated into the solar power system that controls the overflow of voltage from the solar panel into the inverter thus preventing it from any damage.

LCD Screen

The LCD display on the Jackery 240 generator is used to control the device and measure the energy input and output. As you’ll be connecting multiple devices simultaneously, it’ll be difficult to manually track the output of the current. The LCD solves this issue by indicating all the necessary information you need to identify the performance of the power generator.

Battery Maintenance System

The battery maintenance system prevents damage to the solar generator from multiple hazards. It provides protection through short circuit prevention, voltage control, and temperature control. Not only the battery life is prolonged due to this feature but improves overall maintenance.

Indicator lights

To assist you during the charging process, the main switch is equipped with indicator lights that glow and confirm the outflow of current from output ports. You can thus quickly identify if your device is operating or not.


Jackery 240 lithium power station is built for the mass market and therefore offered at a very affordable price. It is an entry-level power generator but loaded with all the specs of a high-end product. It is frequently bought with Jackery SolarSaga 60W Solar Panel in an economical price package.


Jackery has truly built a brand in the solar generators category. All of Jackery’s power stations are highly reliable products. They score the best user ratings on all platforms including Amazon.

Jackery 240 portable power station is no exception either. It is a small-sized high-performance product. It is trusted by thousands who test its limits in extreme conditions.

It has everything that justifies its tag as the best portable power station in an entry-level price range.

We highly recommend this product for a great experience. However, you should be careful while matching its power capacity with your energy requirements.


How can you choose the right power options for solar generators?

To choose the right power option, you’ll have to recognize your power requirements. You’ll have to check the battery capacity of each electronic device that you are going to charge. If you need to charge smaller devices such as mobile phones, cameras, drones, and flashlights, an entry-level solar system is all you need. In such a case, buying a more powerful power station is not going to be useful. Charging and carrying it around will not be a great experience for you either.

What is the best choice for charging a portable power station?

Solar power stations, as their name suggests, are primarily built for converting solar power into electrical power. An inverter is integrated into each product for this purpose. Therefore, the best choice for charging them is solar recharging. If, however, you don’t have access to this power source, you can still charge them through conventional grid power sources.

Should you maintain and repair your solar stations yourself?

A power station is designed and built compactly. These devices have complex mechanical properties. You shouldn’t try to repair it yourself as it may result in damaging the device along with immediate revoking any warranty. You can, however, maintain it but still, you must know how to do it properly. This is to ensure that your power generator has an optimal useful life.

Should you buy Jackery SolarSaga 60W solar panels along with the Jackery 240 solar station?

Buying solar panels with the right wattage can be a challenging task especially if you don’t know much about voltage compatibilities. Jackery is a trusted brand for manufacturing high-quality solar products. Their SolarSaga 60W solar panel is also a highly rated product that is sold separately from Jackery 240 solar station.
