Jackery Portable Power Station Explorer 300, 293Wh Backup Lithium Battery, Solar Generator for Outdoors Camping Travel Hunting Blackout (Solar Panel Optional)ClimatePartner certified

I purchased a Jackery Explorer 300 Portable Power Station on 9-1-2020 and it arrived a few days later via FedEX. My decision to purchase the E300 was based on the results of my previous experience with a Jackery E160, E500 and a Jackery E1000. I found the Jackery Power Station to be very useful, easy to use and easy to charge with the Jackery SolarSaga 100W Solar Panel, AC Charger or the Car Port. I use the E300 to power my small electrical devices during the power outages that often occur after storms or traffic accidents in my area. The E1000 will take care of powering my Maytag Refrigerator/Freezer but I needed another power station and I chose one with more capacity than the E160 for some of the longer power outages.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

This is a great little portable power bank that is perfect for car camping. It's small and lightweight enough to easy to work with from a minivan or teardrop camper. I also own a Jackery Explorer 500--and I PREFER the 300 most of the time when camping.Pros:•durable•functional for most of what you need when car camping--running lights or fans, charging up phones, drones, cameras or your laptop•300W inverter•charges in less than ~3 hours from your wall outlet, USB-C, solar panels or car outlet. If you charge it with a USB-C + wall charger, you can charge it in 2 hours•has 1 USB-C slot, 2 USB-A slots, 1 12V slot and *2* AC outlets--*can charge 6 things at the same time!*•affordable•can charge itself AND be used to run things at the same time (flow through charging)•quiet•love that you can run two large fans off of it for hours due to having two AC outlets!Cons:•Not powerful enough to run high intensity things like an induction cooktop or a blender

I've been using Jackery products for over 5 years. They offer absolutely one of the best power banks on the market today. So when my previous Jackery started (finally) wearing out (it took 5 yrs of abuse to do that!) , I knew I would replace it with another Jackery.If you are boondocking, nomading, overlanding, this power station definitely is robust enough to go anywhere you want. I've used it for months at a time - every single day - on the road, above 8k altitude, at the beach, in the rain, the blazing sun, wretched humidity and brutally cold weather.If you're looking for a backup power supply for your home, boat, RV, or in the garage, Jackery should be your first and only choice. It always works, always charges, always delivers. It is one of the most reliable pieces of equipment I've had the pleasure to own. I am so convinced of its unblinking reliability I started giving Jackery power stations as gifts - because I knew every single person I gift with a Jackery would be completely and totally satisfied with the product's performance. Yes, it's that good.Jackery the company is also 100%. I had a reason to contact Jackery about a particular delivery issue with an order and was ASTOUNDED by their customer service. When was the last time you had a seller on Amazon contact you personally, yes a real human over the phone. They quickly and efficiently remedied my problem with no questions asked. I was absolutely blown away by how professional, friendly and prompt all of the personnel were at Jackery.My opinion is that you will never have to contact Jackery about a problem with their products. They ALWAYS WORK. But now I know (personally!) that this company stands behind every aspect of their product's performance, beginning with the delivery itself. Their attention to my issue was so stand-up, it is the main reason I'm writing this review.Believing in a Jackery product is pretty standard, but believing and TRUSTING in the company behind that product is exceedingly rare in these current times. Jackery deserves its 5-star review from me, has earned it and more importantly, has earned my trust.100% Highly recommend this product and this company.

Great product! Have used it for work and for camping for 2+ years now and I still rely on it. Really useful having all the different ports for different products. Convenient size and lite weight. For what I use it for the 300 watt capacity is good enough - fan in van will run all night at 50% - recharges my bluetooth speaker, runs the led lights, and still have some left over power in the morning. Recharge the Zackery when we're running during the day. I can't remember how long it takes but I think it is less than 4 hours.
