Review: Great for our camper - Good quality
Review: Under promise and over deliver - I purchased this in preparation for a camping trip abroad next year. It was delivered on time, in very nice packaging with a carry case included. Once delivered I fully charged to test with my Philips Dreamstation to see A) would it last a full night and if so B) How long would it last on a full charge. The battery indicator is in the form of 5 bars (so approxiately 20% per bar). I was amazed to see on waking up after the first night (7 hours & 22 mins use) that it still had all 5 bars showing and therefore I'm guessing had used less than 20%. Important to note that I don't use any heating or humidifier, which I would guess would increase consumption significantly. After night 2 (7 hours & 57 mins use) it had 3 bars remaining, so I risked a 3rd night (7 hours & 12 mins use) and it still had a bar indicating on the battery the next morning. I'm not going to risk a 4th night, mainly because I should have access to charge each day when I'm away, so have tested to a worst case scenario for me and happy to report it passed with flying colours. Over 22 and a half hours use, with charge still left in the device. I'm a big fan of companies that under promise and over deliver rather than the other way around and Easylonger fall in to this category based on this experience and will definitely look at other products. If you're a CPAP user who may have the odd night where you don't have access to power, this is a great bit of kit and will come in handy.

### ⭐⭐⭐⭐⭐ Small and convenient.
*by P***Y on 31 August 2025*

This powers my Resmed 10 Autoset cpap machine for 1 and a half nights sleeping for 8 hours a night. Easy to charge and relatively light to carry in luggage. A larger battery would be needed for a number of nights without charging if going off grid.
