The majority of us are dependent on energy in some way or another. Aside from supplying power to our homes, we also use electricity to take pleasure in a variety of life’s occasions. However, this luxury can become a source of additional stress when it is not available, whether because of a power outage or because you are in a location that does not have access to energy.
To our great relief, thanks to the contributions of science and technology, portable sources of power are rapidly expanding their market share. The Jackery Explorer 300 was designed specifically for situations like this one. After putting it through its paces and analysing the results, we can now advise you on whether or not you should put your hard-earned money into this power plant.

Jackery Explorer 300: Design

The Explorer 300 stays true to the Jackery brand by maintaining the same general outline and colour scheme as its more powerful relatives. The sturdy black plastic enclosure has dimensions of 23 centimetres by 13 centimetres by 20 centimetres. The presence of four pads on the underside eliminates the possibility of sliding.
The 3.2 kilogramme generator has an integrated handle that makes it easy to transport it to the location where it is required. The lithium-ion NMC technology used in the battery allows for at least 500 charge cycles before it needs to be replaced.
Operation, Features and Compatibility
Simply plug in the desired input to the terminal, and the screen will illuminate to indicate its current power status. In contrast to the Aukey PowerStudio 300, which features a USB-PD charging connector, this one can only serve as an output.
The process of drawing energy from the battery begins with selecting an output bank. You can choose between USB, AC, and 12V DC with the press of a button. With these toggle switches, you may reduce the Explorer 300’s power consumption while less than all of its outputs are in operation. When you select air conditioning, a fan will turn on; however, this is noticeably quieter than it was on the Explorer 1000, and my tests revealed that this battery also utilises the fan far less frequently.

Jackery Explorer 300: Installation and Setup

The Jackery Explorer 300 was delivered in a sturdy box with protective foam lining. When we pressed the button that activated the LCD screen after setting it down on my desk, the percentage shown was 38%. Next, we read the guide, and we have to give Jackery some credit: This guidebook is far superior than the vast majority of device manuals I’ve had to read in order to write reviews.
Battery Performance and Capacity
The three USB ports are the first thing you’ll notice. USB Type-C (with PD) can supply up to 60 watts of power through the top connector. Powerful Type-C devices can be charged, and many laptops allow for playback even while charging. The next port is a USB Type-A with Quick Charge 3.0 support. This provides the fastest possible charging for an iPhone, 18 watts. The third USB Type-A port provides the final 12 watts of power.
This is not a slow charger; it provides standard USB power, the kind you’d get in a computer. The 12-volt DC outlet operates similarly to the one in your car, making it simple to grasp. There still needs to be additional information concerning the air conditioning outlets. In North America, the standard voltage is 110 volts. However, the maximum wattage is just 300, as opposed to the 1,500 or more watts available from a standard wall outlet.
Final Words
The Explorer 300’s best feature continues to be how small it is. The size of the battery is amazing for that volume. You would expect high-quality construction from Jackery, and that’s what you get with the Explorer 300. We also liked that it could be charged through a USB port. It’s easy to use because the user interface is simple and there are a lot of output sockets. By no means is it perfect. The AC power measurement could be better, and the Explorer 300 doesn’t have a built-in torch, which is useful when the power goes out.

FAQS
A SolarSaga 100W solar panel can quickly charge the Explorer 300 from the sun in 5.5 hours. Easy to carry and strong: The Explorer 300 compact power station is light, stylish, and easy to carry because it is easy to use, small, and has a strong handle.
There are lithium batteries in every Jackery portable power plant. Lithium-ion batteries are usually good for 500 full charge cycles or 2 to 3 years, whichever comes first. At that point, your battery will have about 80% of its full power, and it will slowly lose power after that.
