I am pleased with it.
This battery did the job. I went on a backpacking trip and it was light enough and compact enough to bring along to help with my nightly CPAP needs. It has a nice LED light on the end and worked as well as I needed it to.
Looking for a CPAP powerbank for an upcoming trip, I elected to go with the EXP48 Pro to.meet the need of an 9 hrs. red-eye flight. The battery is functioning as expected. I was a little surprise at it came at about twice the size and the weight expected, but it will come in handy for future offroad trips.
Glad to know I can use CPAP even if my home's power fails.
Awesome product with great customer service and support.
