Battery Capacity

The first thing to expect from a portable power station is its battery capacity. The Jackery Explorer series has different battery capacities for each solar generator in its product line. However, the Explorer 300 stands in the middle of the product line in terms of capacity at 293Wh.

Please note that some machines cannot work correctly on that volume. The good news is that there’s a lot you can power with this battery. Some of the devices that you can use include:

  • Digital Cameras
  • Smartphones
  • TVs
  • Lights
  • Mini-Fridges
  • Laptops
  • Fans
  • Drones

Each device listed above has its own charge times and run times depending on how many watts each device uses. For reference, a 5W light should last for close to 27 hours with the Jackery 300.

Noise Level

Portable power stations are known to be very quiet generators. With a silent power station, you can enjoy your time spent outdoors.

The only time a solar generator makes noise is when it is either cooling its battery down or powering power-intensive appliances or devices. Both of these scenarios involve cooling fans making the noise.

This is not a downside, however, because cooling fans are needed with all solar generators. The noise level will not be an issue if you’re powering your devices at or under the continuous rated output level of 300W.

Charging Ports

Jackery Explorer 300 recharging methods

There’s one thing that is common amongst nearly all portable power stations. This is the need to have charging ports that can charge its battery in several applications/formats.

Since this product’s primary use is for outdoor activities, versatility is a significant point to analyze.

Reviewing the Explorer 300’s charging options below, we can see that there are four ways of recharging the generator. One of those options is from another electric generator. This is by far the least common way of recharging the generator. The most common types of recharging are from solar panels and standard wall outlets.

Output Ports

There are six total output ports on the Explorer 300. They include three different USB outlets:

  • Standard USB-A
  • Quick Charge 3.0 USB-A
  • USB-C PD

Also on the generator are two AC outlets that run at 300W continuous and 500W surge. At 300W, you can charge several devices without an issue.

For example, the highest wattage a smartphone can charge at is 60W. Using the two AC ports to charge two phones at 60W equals 120W, which is less than half of what the AC outlets are capable of combined.

Lastly, there is a covered car port output capable of 120W (12V, 10A).

Size

Solar generators are not always portable. However, many brands produce mobile power stations; Jackery is one of those brands. The largest solar generator they make is the Explorer 1000 and that weighs 22 lbs.

Jackery seemed to have paid a reasonable level of attention to this department. For a 293Wh device, it’s a much smaller option than what other competitors offer.

Size matters a lot when picking power stations. 

For example, the Goal Zero YETI 200X weighs five pounds and has 187Wh of battery capacity. This is the smallest solar generator made by Goal Zero.

The Jackery Explorer 300 weighs 7.1 pounds and has 293Wh of capacity.

The capacity-to-weight ratio of the YETI 200X (187/5) equals 37.4Wh per pound. The ratio of the Explorer 300 (293/7.1) is 41.3Wh per pound. This shows that the Jackery 300 packs 9.5% more power per pound than the 200X.

Another comparison that is closer to the Explorer 300 in power and weight is against the Rockpals 300 solar generator.

The Rockpals 300 weighs 7.5 pounds and has 280Wh of battery capacity.

Once again, the Jackery 300 is 7.1 pounds and has a 293Wh capacity.

We already know the capacity-to-weight ratio of the Jackery is 41.3Wh per pound, now let’s take the Rockpals ratio by dividing 280 by 7.5 to get 37.3Wh per pound. The Explorer 300 has 9.6% more power per pound than the Rockpals 300.

Keep in mind that the Rockpals 300 is one of the best solar generators for its size, so having more power in their generator is an excellent achievement from Jackery.

The main reason why people buy systems like the Explorer 300 is because of its portability. Therefore, having a system that is light and powerful is crucial to choosing the ideal generator.

The size of the 300 is just a bit too large to carry on a backpacking or hiking trip. However, for camping out, this is an excellent generator because it can be carried short distances without a problem and is small enough to fit inside a tent without taking up too much room.

Cost 

The Explorer 300 retails for $299.99 on Amazon (affiliate link). Compared to the similar Rockpals 300, their system is priced at $269.99. Overall, the Rockpals 300 would be my personal primary choice. But this comes with a few downsides that may make or break your purchase decision.

  • The Rockpals 300 doesn’t have a USB-C port. It has four USB-A ports with two of them being quick charge 3.0 ports, but no USB-C, which is not ideal for fast-charging technology.
  • The Rockpals generator comes with an 18-month warranty, but Jackery’s warranty is for 24 months.
  • The Jackery 300 has a regulated 12V output and the Rockpals 300 does not
  • The Rockpals’ display screen does not tell you how much power is going into the system when charging it. The Explorer 300 does have this feature.

  • Fast Charging: If you’re familiar with the solar generator market, you should know that fast charging is a big deal. The Jackery Explorer 300 features an MPPT charge controller. This build encourages fast charging. With a solar panel, it reaches full charge in 5.5 hours (SolarSaga 100W solar panel).

Cons

  • Incompatible With Certain Appliances: The Jackery Explorer 300 doesn’t work correctly with all devices. Heavy devices like blenders, pressure cookers, and hair dryers are not compatible with this device. However, this is understandable due to its battery capacity.
  • High Price Point: The price of this generator is quite high compared to similar models. The solar generator market tends to have higher prices with companies that have established brands. Jackery is one of those brands and so is Goal Zero. Jackery’s generators are typically not very expensive, but the Explorer 300 is expensive for what it offers.
