Unit is very small and portable and appears quite nice. I bought it to run my Philips Dreamstation CPAP thinking it might be enough without breaking the bank. It worked well, but the unit went from a full 100% charge to just 7% remaining in the morning when I woke up. No complaints (it "is what it is" as far as how much power my CPAP draws), just hoping to help others understand what the capability of the unit actually is.

Unlimited power. I can charge all my digital devices using the Jackery 300 with a Jackery solar panel. I have the 60w and 100w Solar Panels and while the 100w will help you maximize solar absorption while charging other devices, the 60w will get you by. If you get 80w from the sun with the 100w Panel, you will gret 40w from the 60w panel in the same sun. You will never get 100% efficiency rate with either panel. Most I’ve ever gotten with the 60w is 51w of solar so just keep that in your back pocket.Only giving 4 stars because of the complete lack of responses to my emails to hello@jackery.com. They claim to respond to this email but I have sent 3 positive emails at different times this year none of which were responded to.Also giving 4 stars for the lack of a DC extension cable for the solar panel and lack of a temperature controlled charging case/bag. Yes they sell a bag for storage but not one you can keep the battery in while cables are plugged in and it’s being charged or charging. Ironically the panel has to be in the sun but the battery itself should not be as it needs to stay cool or it might explode. A longer dc extension cable and charging case are two obvious solutions to this problem neither of which Jackery has seemed to invest in.I do like Jackery but there is definitely more “meat on the bone” that the company is currently not offering. They used to have smaller powerbanks as well that they no longer sell and that’s a real shame as it would just add to their solar battery charging system. In my picture I have a mophie battery, but I also have multiple Anker power banks I charge using the Jackery 300 and these are mainly what I use to keep my devices powered. I also have eneloop Rechargable AA and AAA that I also power with the Jackery 300. With my current setup I can offset most of my power needs to solar.I will be purchasing bigger batteries and bigger solar panels in the future and may continue to stick with Jackery. But if another company introduces a more well rounded Apple style charging system I will have to switch to that because it doesn’t seem like Jackery wants to interact with their customers other than share photos of people using their solar system on instagram (which just helps them advertise their products it doesn’t help their customers at all).But if you are reading this Jackery this is what I want:-Solar Panel DC Extension Cable-Jackery Temperature Controlled Charging Bag/Case-Revamped Jackery 100 (smaller like the Anker powerhouse 100)-Smaller Jackery Power Banks (10k, 20k, 30k)-Jackery Rechargeable AA , AAA, 9V batteries with chargers-More accessories (usb to dc cables, 12v to usb, 12v to dc, jackery breakout box)- A jackery charging guide that shows you what you should be able to charge with each unit rather than trusting their infographics which are hard to understandSome of these do not need to be first party but they do need to be at least recommended by Jackery or made to fit jackery. I just believe by having a wider expanse of accessories to fill more needs would help the Jackery company make more money while at the same time help move more people over into solar power for basic needs.

This is a great phone or laptop battery charger in an emergency, that’s about it. Don’t expect it to power a fridge or other larger appliances in an outage.

Good host of features for a self-contained little system. Highly recommend getting an MC4 adapter if you want to make use of solar panels that aren’t made specifically for this unit, but honestly I mostly just charge it from my car’s 12v outlet. Obviously the power bank isn’t huge, but this is the lowest capacity model, so you probably know what you’re signing up for off this is the model you’re looking at. I wouldn’t hook up a DC fridge for more than a few hours at a time, and forget about anything with a heating element (microwaves, hot plates, tea kettles), but this thing is great for changing phones and laptops, usb charged lights , running a mobile hotspot, and I might even hook up something like a gaming console for a while. Very good for plug and play right out of the box, good enough that I’d consider upgrading to a higher capacity model in the future if I have need of it

Very portable.Ran a 42 inch LG TV for about an hour with use of 70% charge.Auto vac wouldn't work.Charged phone and solar crank radio easily with very limited power usage.Obviously need something bigger; much bigger for appliances.

Purchased this item to power my 110vt A/C items requiring less than 300 watts during what seems to be ever increasing Utility power outages. This item easily powered my 50” LED T.V. for many hours. It can also power my internet Router at the same time. The construction is solid with an easy to read digital display that has a back light option. It comes with an A/C charger and a 12vt car type charger. I purchased this primary for the A/C plugs, however it has a dc plug along with a USB A, and C option. For emergency power or use while camping I highly recommend this product.

Keeps a full charge. Very easy to carry around. I can run most house hold goods or keep power if needed while in the outdoors

It’s very convenient and can charge or power most things. I’d wish its max watts was higher but I just didn’t want to spend so much more. Great for charging batteries and running little things while camping or working outside. I do wish it had another outlet but that hasn’t bothered me too much. Overall really like.

I really needed a portable power source during stops. I have a 300w mini heater to reduce cold &/or humidity to an uninsulated van without draining its battery. It arrived in 1 week from CA! Looks practically new, too! First time, it charged up to 99%. Then I tried charging it with a 100w Jackery solar panel infull northern sun (Sep). Incoming charging fluctuated btw 65-85w at roughly 10w, but increased rapidly as it neared 82%. I topped it off with 110v due to time contraints & it reached the full 100%. I will update this review after I try all the plugs. Thank you Amazon!!
