I researched Jackery for a year before purchasing this. It works for everything I need and more. Portable- charges fast-

Very convenient for power during camping or modest backup at home. Study, functional and responsive customer service.

I tested this unit charging my cell phone and it seems to work great. Not really going to be able to put it through its paces until this weekend camping at Peach Fest.I will say though that Jackery's customer service is excellent. After buying the product, I noticed the price dropped a couple days before I received it. I contacted them through Amazon and they immediately gave me a refund for the discounted amount. They definitely won a fan of their products so far and I will be buying the solar panel soon to go with it.

I am a musician and I bought this to power a Bose L1 Pro8 portable sound system. I was able to play a 3-hour set at a noisy local brewery and had 71% battery left.If you want to power more items, like a mixing board, larger speakers or a guitar amp, I recommend getting a larger model but, for my Bose system, a full charge offers 10 hours of playing time.I highly recommend for buskers, solo musicians or if you just like playing music on the go.

Works great with Resmed Airsense 10 Autoset. I completed using the Jackery for day five and still have 38% power left - four days at 7-7.5 hours, one day at 9.5. My CPAP settings are 8-16 for the air pressure. So here are the tips for extended use. I tested one night using the normal electrical outlet plug and it drained 28% power in one night. This is very inefficient, because it has to convert DC to AC power, and then your Resmed adapter has to convert it back to DC. Avoid this by buying a car charger adapter made specifically for your resmed that plugs into the DC car charging port on the Jackery and then into the back of the Resmed. Resmed sells a version and it is quite expensive or you can buy a quality aftermarket like the KFD DC Adapter Car Charger for Resmed S10 available on Amazon. Other reviewers mentioned this charger and I can confirm it works well. Using the KFD and after recharging the battery again, I'm using around 11 % power for a typical 7-7.5 hour night. This is phenomenal. The second major tip, and one that enables this, I don't use a heated tube and humidifier. Resmed makes and you can buy an endcap that takes the humidifier out of the picture. Look up Resmed 37303 or 37335 end covers. I never use the humidifier and heated tube but if you do, you can temporarily choose not to use them when on battery power to maximize your battery use. Just remember to buy the end cover. Finally, you must remember to hit the switch next to the port to turn it off immediately when done or it will continue to bleed power whether you are using a powered device or not. The green light centered in the switch button next to the specific port should be off after using!!!! Overall, this feels like a quality unit. Time will tell whether it holds up. Another reviewer mentioned that they have used a somewhat new battery manufacturer for this particular unit, so the jury is still out on reliability but fingers crossed that Jackery hasn't jeopardized its stellar reputation by trying something new at a better price point that sacrifices quality and longevity. Ratings for this on Amazon have been high so far, so that is encouraging. I'll update if needed but I'm impressed so far! And never again will I have a horrible nights sleep without my CPAP.

Excelente el mejor producto, su autonomía es increíble

Glad I bought this very nice portable power bank

Alright, I've given a few reviews over time but this one is important to me. I've bought a few smaller battery recharging devices in the past. Mostly smaller objects that would give a phone or iPad a recharge. I bought one a couple years back for $60, the block which is the size of a paperback novel and weighing about half as much as the Jackery gave me 2-3 full recharges. About 3 hours of charge time before it would die. Living in the country, and a place rural enough that power outages can some times take hours on end before they are fixed, it's important to have backup options.But the last couple years that's been even more important as I was setup with a Cpap machine. We don't own a home generator, or any real backup system. So after hours of debating and reading reviews I chose to buy a Jackery even though there were some one star reviews, because for all the reviews they were above overwhelmingly positive.So here is my own review. I bought the Jackery 300 and it came to me with a 43% factory charge. I plugged it in and charged it up to 100%. I immediately tested the product that night using my Resmed AirSense 10. For anyone using a Cpap that's one of the newer models in the last couple years. Like a $999 Cpap. I set my humidity and heat both to off and tested it overnight. I also watched the Jackery display here and there. So my Cpap was stably drawing between 9-12 watts from the Jackery on an air pressure of 7-15. Effectively meaning the Jackery can run the Cpap for 24 hours or 3 nights of sleep before needing a recharge as long as it keeps at that watt usage.I have tested it as well with my Galaxy s10 cell phone. Just checking webpages and Facebook -while charging- it uses 3 watts. Using it for YouTube videos it runs 4-6 watts. Using it for Tiktok it ran up to 8 watts initially and then dropped down to 4-6 watts right after. This thing can run a cell phone for two days straight without dying by those standards, if not more. Though, I wouldn't let the charge go under 20% on the Jackery for healthy battery life.I'm going camping this week, going to be nice for the first time in awhile having a way to keep my cpap running away from home. As well having a way to charge a phone. So the applications for this are many, but the ones that will help my family the most is for camping trips, long car rides with my teens needing to keep their phones charged without relying on the car battery, and power outages to maintain both cpap for my health as well as cell phones/laptop for entertainment. Even a medium size fan on low runs 29 watts. So a nice way for sone air flow.I would recommend this product to anyone who camps, travels, deals with power outages, lives off grid, or has an rv and needs a backup option for electricity. I was concerned at the price, but now I'm glad I didn't hold back. Hope it's as helpful to you all and my review gave you some reassurance.

Live saver, light weight & i’m very satisfied with my purchase.

This is my 6th Jackery Explorer Battery.I currently use two 1000 watt Jackery Explorer batteries and one 300 watt Jackery Explorer battery.I retired my old batteries, a 1000 watt and a 160 watt after HEAVY HEAVY use for 3 years. I gotta say they have never let me down. EVER. They never shut off for no reason, they charge even on pooey solar days, they work when its 20 degrees out and when its hot. They have been EXTREMELY reliable.My 6th battery was the new model 2000 watt Jackery PRO. That one that was a royal pian. It shut off with stupid error codes every few hours. They changed the input on the 2000 Pro also. Now it's an 8mm 8020 instead of the original 7909. If you use their adapter, the plug will stick out 3 inches. Can we say "snap!? I'm a full time vanner and that just doesn't work for me. It was like growing roses. Thorns and all.So I'm so happy that they still make this particular 1000 watt model! They didn't change the input ports. They are still the original 7909 8mm inputs. The included Anderson splitter (1000 watt) is still the 7909 8mm also. The only useless thing I've seen so far is the stupid light on the side. If I'm going outside at night, I'm not hefting a 1000 watt battery with me. Geesh!So as I just got my new Jackery 1000s and the 300, I will update as time passes.PS - The solar panels are still junk! 2 dead with minimal use. Sudden deaths. Not reliable either.
