I am trying to find a battery power source to run my CPAP machine? I need to be able to plug into a standard 110 outlet to power my machine for use during the night. Then I will need to recharge the battery power supply during the day. Will the Universal 120VAC UPS Battery backup satisfy my needs? I have researched the power demands of the CPAP machine that I use and the information is sketchy. This is what the manual says: Supply Voltage 110-115; Current Input 1.27 A (1.43A Max) and Rated Supply Freq. 50-60 Hz/400 Hz.
