Product is solid. My only issue was that it took a very long time to show up after my credit card was charged. After a call to customer service, an injury was initiated. Seems that the item was out of stock even though the web indicated otherwise. Item arrived today. Start to finish, plus one phone call was 14 days. Overall, not as fast as I had hope for, but it did arrive. As represented. So, only 3 stars as the order process failed. To their credit, customer service did solve the problem. But only because i inquired. Charging my credit card and not shipping is not right.

The biggest problem with the battery pack was lack of having the owner manual link. Once I received the link it works great. The other item to realize, which might be intuitive but wasn’t to me, is you use your CPAP power cord in conjunction with the adapter to charge your battery. Loved this for RV’ng without having power.

I was wary of paying the listed price for an adapter, which I assumed would be like other ones around the house. In fact, this is a robust and hefty unit which is probably worth the money. It certainly will not fit in a purse or handbag. It is a simple matter to get a deep-cycle battery or two and a perpetual charger and have a system which will run at least all night and maybe longer. Our longest outage so far has been three days, and that is what I planned for, with two batteries. I bought a small NOCO charger from another vendor. AT ALL TIMES AVOID ACCIDENTALLY CROSSING THE BATTERY TERMINALS. This warning should be more prominent in association with this wiring set.
