This is a nice light battery pack and for the amp-hour rating and price, is a better deal than some competing sites. I didn't do my research well enough and found that there isn't a practical way to charge this from a DC source without using an inverter so for my needs, it didn't work. However, the battery pack itself is nice and light, charges relatively quickly with the included AC charger, and comes in a nice carry case. I plugged my ResMed S9 into it using the ResMed 90 watt DC adapter and it powered up correctly.

CPAP machines are small but that doesn't do much good if the battery you have to lug around is big. This battery looks like a great choice. I haven't used it with my machine yet, but I can't wait to have a small battery for camping.
