*writing from Canada - Bought lowest power option as I am primarily using for laptop/cellphones/lights I come from a background of just using powerbanks for phone chargers, but really hated how they take hours and hours to charge, or die off when it drops below freezing. I seeked out Jackery simply because it was mentioned over and over again in car camping/campervan conversion forums as the #1 go to. Things I like: 1. Durable quality parts - It feels high quality, not cheap. It's much lighter then I thought, the grab handle is awesome and kudos for adding a rubberized bottom for grip so it doesn't fall over, very smart. 2. Resists cold - I've used this in -18 celcius (0 Fahrenheit) and the charge does not remotely get affected, doesn't deviate at all. Most powerbanks lose charge fast at those temperatures, not this one!

I was a bit reluctant to get this battery due to the fact that I knew Resmed charges $1200 for their AirSense 10 battery, so I wasn't sure whether this unit would do a comparable job, given it is a fraction of the cost. I got the Explorer 240 in hopes that it will provide sufficient power to my CPAP Airsense 10 (no humification, no heated tube) for 2 nights camping with the family recently. I have bad sleep apnea so I have needed regular CPAP for over 12 years now. The last couple of times camping without it have resulted in very poor sleep for me and annoyance for my family with the incessant snoring. My kids did not really look forward to a repeat performance, so I thought I would try to mitigate the eventual complaining by picking up the Jackery battery. It was really through online reviews that purchasing this product became compelling. It was received quickly by Canada Post and packaged very professionally and it was delivered to me a day or so before my camping trip.

This is very impressive power station. It's very light, small but the power is really more than you expect. I bought a rocksolar powerstation thats even higher wattage but it won't power our portable cooler but this Jackery give power till the last remaining power even 1%. Definitely will buy again in the future ill stick now to Jackery in terms of power station.

Picked this up before going on an 11 day camping road trip through Oregon and am super glad I did! It has enough punch to power the majority of laptops out there and can easily charge a handful of devices at once. We used my phone as a GPS and music/podcast player for the entire trip, simply kept it plugged in the Jackery and never had to worry about my phone being at low battery or dead once we arrived at our destination. Being able to charge the Jackery with the provided car adapter made it for the perfect solution. We kept it in the back seat and ran an extension cable to the front, we where able to charge our two phones and a macbook air all from the comfort of the front seat. I would highly recommend Jackery products to anyone looking for a solid, reliable portable power solution. The 240 is perfect for us as we mostly use it to power phones, laptops, tablets, and Nintendo Switch but they offer many different sizes to accommodate more power hungry applications. Worth the price.

Read several reviews indicating the device can run a CPAP for 2 nights but not in my first attempt. The device is small and compact and appears good quality. It is user friendly with and LCD display indicating battery charge using bars and %. I rec’d this this week and fully charged it and used it the same night with a Resmed 11 CPAP. Went to sleep around 11 pm and awakened 06:15 with 3 percent remaining. Im suspect a persons respiratory rate may affect the pump and cause it to work harder and drain a little more battery if you have a higher rate then other but it shouldn’t be dramatic. I hope this helps anyone else looking to purchase this for any reason. Follow up: I have used my Jackery on my CPAP again but turned off the Humidification and tube warmer and just used it dry. After 7 hrs and waking in the am I checked the charge on my Jackery and it was at 74% (only used 26% of the charge). my guess is the other CPAP features use much more power.
