FAQ
Q1: What devices can the Explorer 300 power?
A: The Explorer 300 can charge/power devices that operate at less than 300 watts and the total wattage of all connected devices should also be under 300 watts as well. If the power requirement exceeds this limit, the Explorer 300 will automatically shut off. Please check your device's specifications before making a purchase.
Q2: How can I know the working time for my device?
A: You can calculate the working time using the formula: Working time = 300Wh*0.85/operating power of your device. For example, if the power consumption of your device is 60W, the estimated working time would be approximately 4.3 hours. Please note that actual power consumption may vary based on different usage scenarios.
Q3: How long does it take to fully charge the Explorer 300 power station?
The Explorer 300 can be fully charged in approximately 4 hours via AC wall outlet. Alternatively, you have two other recharge options: around 4.5 hours from a car port and around 5.5 hours from a Jackery SolarSaga 100W solar panel (sold separately).
Q4: Can the Explorer 300 be charged while in use?
A: Yes, you can use the Explorer 300 to charge devices while it is being recharged at the same time.

The Jackery Explorer 300. What is it? Some know it as a power station, some know it as a solar generator, and some have no idea nor clue as to what the unit is or how to even utilize it. This review should shed some light on that and get you folks up to speed and in the know in regards to what there is to know about this new Jackery Explorer 300 power station / solar generator.
Portable power generation and storage. The new Jackery Explorer 300 released on September 1st, 2020 of this year is Jackery’s latest and greatest product to hit the off-grid power sector. Their products are used by campers, nomads, tailgaters, and preppers alike. The Jackery power stations are portable power solutions that can be powered or recharged via solar power, automotive 12v DC, AC 110v home / office outlet, or shore power connection from an available external power source at a camp site / RV Park.
Jackery Explorer 300 features the latest and greatest in tech with it’s modern USB-C PD output port, USB-A QC 3.0 output port, addition of a second 110v AC receptacle, and an all new MPPT charge controller built-in to the unit to allow for rapid and sustained high-speed charging, doubling that of the previous Jackery Explorer 160 and Explorer 240 models on the market. Weighing in at only 7lbs, this new Explorer 300 model is the pinnacle of lightweight and portable power! Paired with a Jackery Solar Saga 60 solar panel and you would be sustainable with unlimited green power whilst backpacking / hiking out in the wilderness for days on end.
Power Stations / Solar Generators like the Jackery line of products, specifically the Explorer 300 are perfect for van life nomads like myself whom are not into complicated DIY custom built setups and just want the convenience and robust nature of a simple all in one power station with built in I/O ports that the Jackery Explorer 300 offers. This solution is for the “grab and go” lifestyle and requires no thought or setup whatsoever as the Jackery Explorer 300 is dummy-proof in regards to deployment and using out in the field or in your vehicle.
The industry leading two years manufacturing warranty gives you a peace of mind knowing that Jackery stands behind their products and has you covered in the event you run into any issues. Jackery is based out of California, USA and has an award winning customer support staff on their team to answer any questions or provide you with any product support you may need. All of my interactions with Jackery customer service has been nothing but positive since day one as I am a longtime customer of theirs since 2019, purchasing and owning of their Explorer 500 power station and as well as their Solar Saga 60 solar panel. In fact, I own two of their Explorer 500 power stations, but that’s neither here nor there.
Devices I plan to power or recharge with this specific unit include, but are not limited to; iPhone XR, PlayStation Vita Slim, Nintendo Switch Hybrid v1.0, Razer Blade Stealth 13 | Late 2019 Ultrabook, Insignia 19” 720p TV, Opolar 9” rechargeable fan, Aukey touch lamp, Goal Zero Crush Lantern, HotLogic Mini 110v oven, Alpicool C15 12v compressor refrigerator.
Included in the package:
(1) Jackery Explorer 300 Power Station
(1) Soft zippered pouch to store power cables
(1) 110v AC wall / shore power adaptor
(1) 12v DC automotive power cable
(1) 2 year warranty miniature Jackery card
(1) User Manual / Quick-Start Guide
(1) Jackery product satisfaction tree flyer
Pros:
-Lightweight portable power solution at only 7lbs!
-USB-C PD output port at 60 Watts!
-USB-A QC 3.0 output port.
-DC 12v output is regulated at 13.3v
-Upgraded beefy 12v DC to 8mm power cable.
-300 Watt / 500 Watt Peak Pure Sine Wave inverter with two receptacles instead of one.
-MPPT charge controller built-in vs the PWM charge controller on Jackery’s older units as well as much cheaper power stations on the market. MPPT allows for significantly faster recharge times.
-Pass-Thru charging! The Jackery Explorer 300 can be recharged and discharged at the same time. Collecting solar power (solar panel sold separately) and using it to your hearts content!
-Robust backlit LCD that contains all pertinent data user may need to know in regards to device power usages, input, output, and operation. Included battery percentage, battery segment visual graph, as well as input and output wattages.
-High / Low temperature alarm indicators.
-Auto-Power off if left running for 12 hours without a significant load exceeding 10 Watts applied to the power station. This will save battery life and cycles.
-Low Battery Warning. LCD screen will flash ten times at 20% and 10% power remaining to signal to user that the power station needs to be recharged.
-Warranty! Industry leading 2 years manufacturing warranty with ability to extend 12 additional months via registering your product purchase on Jackery’s website!
-Lifetime Technical Support! Have any questions? Contact Jackery Customer Service Department. They are headquartered out of the United States in the State of California and they will get you taken care of.
Cons:
-No wide area light / lantern included on the back of the unit like some other power stations on the market in this class include.
-USB-C PD port is output only. Does not accept input for charging.
-No USB-C to USB-C cable included with the package
-DC 12v Automotive Port is only rated at 10A, and is unable to power a Slime 12v automotive tire air compressor.
Final thoughts:
The Jackery Explorer 300 is a robust piece of kit to own for your camper van / RV, vehicle of choice for tailgating, carry in your backpack for hiking, or store on a shelf at home for emergency preparedness in a grid down scenario. Despite the few shortcomings of the unit that could be addressed by Jackery in future revisions of their power stations, the advantages this lightweight and compact power station offers make it completely a worthwhile investment and I am quite happy with my purchase! I plan to use the Explorer 300 in my 2017 Ram ProMaster City camper van on a daily basis in conjunction with my Jackery Explorer 500 and my Jackery Solar Saga 60 solar panel. I hope to purchase a Jackery Solar Saga 100 solar panel one of these days to perform additional testing with the Explorer 300. I rate the Jackery Explorer 300 a 4.5 / 5 Stars (9/10) rating here on Amazon and I highly recommend purchase of this product should you find yourself wanting or needing off-grid power for whatever reasons you may have. You will not be disappointed. Jackery will guarantee it.

I have tested the E300 with several LED & CFL lights that can be used in table lamps and the best one is a 14W Grt Val 1500 Lum LED 'DayLight' bulb, It draws 20 Watts and the E300 will power it for 12-14 Hours from 100% to 10% battery charge levels. The fan will run part time and is very quite. I place the LED light bulb in a small table lamp and it can be moved as needed. You probably already have LED's in your table lights so just use one of them. I also tested a Philips 11 Watt 1000 Lumens LED light for 6 Hours and the E300 charge level decreased from 90% to 60%. I also tested a 5 Watt Onite 400 Lumens USB LED light for 9 Hours and the charge only changed from 90% to 75%. Any of these three choices are a big improvement over my LED lanterns that start out bright but quickly dim unless you run them on low power. As a result of purchasing the E300 I have retired several of my D-Cell LED lanterns that were being used for the power outages and replaced them with table lamps, rechargeable LED Lights and flashlights with rechargeable AA & AAA batteries.
I have a UPS to protect my desktop computer that gives me 20 minutes of runtime in a blackout but if I plug the UPS with the connected computer into my E300 I can extend the operating time at least two more hours. My internet also provides my telephone service and the U-Verse modem needs power or I lose telephone service. The Power Lift Chair can operate from the E300. The "Merlin@Home" Transmitter needs power to send pacemaker data and worked just fine when tested.
I like having more than one power station because I won't need extension cords for each device that I want to power and that also lets me place then in different parts of the house. The E300 has some new features that were not on the E240. The AC Inverter is now 300 Watts (pure sine wave), the 13.3 Volt regulated car port output has a nice cover and the USB output has 60W PD USB-C, QC3.0 USB-A, USB type A port (2.4A). The MPPT charger provides faster charge rates from solar (5.5H), AC (4.5H) and from a car port (5H).
An important feature of the Jackery Explorer 300 is the pass through charging can be used to supply power continuously to a critical load by charging the E300 from the DC Carport on another Jackery Explorer. If the load on the E300 is 75 Watts or less the E300 will stay almost fully charged. The Jackery (E1000, E500, E440, HLS290, E240 or E160) can supply power until their battery is exhausted. This method will allow you to keep the E300 in a critical place without the need to move it outside to recharge by a Solar Panel or Generator. The other Jackery Explorer unit can then be moved and recharged as needed. The DC charging cable you will need is supplied with the Jackery Explorer 300.
The E300 is much more useful than just for power outages and I am discovering more uses every day. The E300 provided power when the wife needed a heating pad while setting in a wheel chair a few days ago. I have a solid state Oscilloscope that the Jackery E300 can power for several hours and that makes one of my best pieces of test equipment truly portable. The E160 and the E300 are used to provide power for my Ham Radio equipment when operating at temporary locations.
Two things that would help with my Ham Radio Equipment is the addition of Anderson PowerPole connectors on the DC input and DC output. This would help when charging the E300 and powering my radio equipment from the E300. The ability to turn off the "Auto-power off feature when the draw is under 10 watts" would really be handy. This feature is great for saving the battery but not so good when powering tranceivers that are monitoring an emergency radio frequency. You just might miss your call.
For maximum battery power, charge Lithium-ion Batteries every 6 months to compensate for the self discharge and for longer life, charge before going below the 20% charge level.
The Jackery Explorer 300 is well worth the price and is expected to provide excellent service for many years.
Here are some photos of just a few of the items that the E300 can power.
Jackery Explorer 300 Waveform; Heating Pad on Wheelchair; AA & AAA Battery Chargers; Rechargeable lights; Ham Radio Equipment; Jackery Explorer 300 with accessories; AC, DC & USB fans; Solar Charging in Morning Sun; Power lift Chair; Oscilloscope; AC, DC & USB Powered Lights

You probably already have LED's in your table lights so just use one of them. I also tested a Philips 11 Watt 1000 Lumens LED light for 6 Hours and the E300 charge level decreased from 90% to 60%. I also tested a 5 Watt Onite 400 Lumens USB LED light for 9 Hours and the charge only changed from 90% to 75%. Any of these three choices are a big improvement over my LED lanterns that start out bright but quickly dim unless you run them on low power. As a result of purchasing the E300 I have retired several of my D-Cell LED lanterns that were being used for the power outages and replaced them with table lamps, rechargeable LED Lights and flashlights with rechargeable AA & AAA batteries.
I have a UPS to protect my desktop computer that gives me 20 minutes of runtime in a blackout but if I plug the UPS with the connected computer into my E300 I can extend the operating time at least two more hours. My internet also provides my telephone service and the U-Verse modem needs power or I lose telephone service. The Power Lift Chair can operate from the E300. The "Merlin@Home" Transmitter needs power to send pacemaker data and worked just fine when tested.
I like having more than one power station because I won't need extension cords for each device that I want to power and that also lets me place then in different parts of the house. The E300 has some new features that were not on the E240. The AC Inverter is now 300 Watts (pure sine wave), the 13.3 Volt regulated car port output has a nice cover and the USB output has 60W PD USB-C, QC3.0 USB-A, USB type A port (2.4A). The MPPT charger provides faster charge rates from solar (5.5H), AC (4.5H) and from a car port (5H).
An important feature of the Jackery Explorer 300 is the pass through charging can be used to supply power continuously to a critical load by charging the E300 from the DC Carport on another Jackery Explorer. If the load on the E300 is 75 Watts or less the E300 will stay almost fully charged. The Jackery (E1000, E500, E440, HLS290, E240 or E160) can supply power until their battery is exhausted. This method will allow you to keep the E300 in a critical place without the need to move it outside to recharge by a Solar Panel or Generator. The other Jackery Explorer unit can then be moved and recharged as needed. The DC charging cable you will need is supplied with the Jackery Explorer 300.
The E300 is much more useful than just for power outages and I am discovering more uses every day. The E300 provided power when the wife needed a heating pad while setting in a wheel chair a few days ago. I have a solid state Oscilloscope that the Jackery E300 can power for several hours and that makes one of my best pieces of test equipment truly portable. The E160 and the E300 are used to provide power for my Ham Radio equipment when operating at temporary locations.
Two things that would help with my Ham Radio Equipment is the addition of Anderson PowerPole connectors on the DC input and DC output. This would help when charging the E300 and powering my radio equipment from the E300. The ability to turn off the "Auto-power off feature when the draw is under 10 watts" would really be handy. This feature is great for saving the battery but not so good when powering tranceivers that are monitoring an emergency radio frequency. You just might miss your call.
For maximum battery power, charge Lithium-ion Batteries every 6 months to compensate for the self discharge and for longer life, charge before going below the 20% charge level.
The Jackery Explorer 300 is well worth the price and is expected to provide excellent service for many years.
Here are some photos of just a few of the items that the E300 can power.

Not only does this thing have so much battery capacity in it, it charges so fast from the included wall charger. Got a USB-C charger for a laptop? Plug it in, double it up with the wall charger and charge ever faster.
Rapid charging that fast is hard on any battery so I only use this feature if I really needed it quickly. Otherwise I just trickle charge it overnight from a regular USB phone cord.
I have two 40 watt solar panels that I have with a cigarette lighter port at one end so I can charge it up solar. The 12 V charger adaptor comes with this thing. It charges decently fast with solar.
The inverter is a little bit on the small side but it’ll power most regular things. If you’re thinking about this for an emergency, it’s not going to power a kettle for a fridge or toaster for that matter. It’ll power a CPAP machine and I found it powers a tiny personal slow cooker that I have.
To sum it up, I wholly recommend this thing. If your energy requirements are at a minimum and, you’re using this for recreation and not emergency use, this Jackery will fit the bill. This is a good starter system to get your toes wet in solar power stations.
