First, let me assure you we are not sponsored by this brand (I’m sure they have never heard of us) despite this being the second review we have done for this brand of CPAP batteries lol. We bought the Easylonger ES720 Backpacking CPAP Battery with our own money in our search to find a battery bank that will power Jerry’s CPAP while backpacking.
Anyway, I came across the Easylonger brand, and it seemed promising. The first one we tested was way too big and way too heavy (coming in at 6 pounds), but did power his CPAP for 9 nights. That one, however, would be great for car camping, multi-night motorcycle rides, or overlanding.
I noticed they had a smaller version that weighed 3 pounds less and would make more sense for backpacking. It comes in at 3 lbs 5 oz on my scale. Yes, it is still “heavy” but way lighter than other options. It also gave him 5 nights of 8-hour run times for a total of 40 hours (actually almost 40 1/2 hours).

Testing Conditions
We tested this out at home for our first test (our real-world test will be next month when we do the Greenbrier River Trail). He used his ResMed Air Mini on a pressure setting of 9 with a full face mask and non-heated hose.
What We Liked
40 hours of run time – We were pretty impressed that the Easylonger ES720 Backpacking CPAP Battery gave him five solid nights of use, perfect for long trails where you will stop in town every 4-5 days to recharge and resupply. You could actually make it every six days since you get five nights of use.
Multiple ports – It has a USB, (2) USB-C, DC, and 12V ports to charge many devices (not just CPAPs) in the event you want to use it for something else when you aren’t backpacking.
Multiple Ways to Recharge – I love that it can be recharged via solar panel, standard USB-C cable, or via the wall with the DC adapter.
Pass thru charging – We were able to recharge the Easylonger ES720 Backpacking CPAP Battery while using the CPAP and changing a phone. We plugged it in at bedtime, plugged the CPAP and phone into the battery bank, and by the time we woke up 8 hours later, the battery bank was fully charged as well as the phone. This is great because that means we won’t need to bring the CPAP wall charger, therefore saving some weight.
What Needs Improvement
First let me assure you that the following features on the Easylonger ES720 Backpacking CPAP Battery work very well, however, since we are using this strictly as a CPAP battery, we find them unnecessary and extra weight (something you don’t want when you are backpacking).
Get rid of the light – There is no reason for the light (most people carry a headlamp anyway) and it causes the battery to weigh more. Some weight could be saved by removing this as a feature.
Wireless Charging – While this is great for those who will be using this to also charge their phone it causes unnecessary weight just like the light.
Overall Impression
We are super happy with the performance of the Easylonger ES720 Backpacking CPAP Battery and how long it lasted. While it does weigh three pounds, the fact that you can get 5 full nights out of it is pretty impressive and in my opinion, is the best option for CPAP users who backpack and cannot be without their CPAP. We love the fact that it has pass-through charging which allows us to ditch the wall plug for the CPAP on trips therefore saving more weight.
We do wish that they would get rid of the wireless charger feature and LED light as this would allow some weight savings and isn’t necessary if you are using it strictly for a CPAP battery. But overall, this is (so far) the best option for a long-distance backpacking trip.
They do have a 40000 mAh one as well that we would like to test out. We have reached out to the company in hopes they would be willing to send it to us. We estimate we could get 3 nights with it and according to them it weighs only 1.3 pounds, so stay tuned!
