I use a couple of the POWERWARE (Now EATON) RM5125 SMALL UPS UNITS in connection with my Emergency Radio OPS when on WX and other ALERTS using my OFF-ROAD POPUP trailer setup. My computers are LAPTOPs but do have WIFI printers and other 120VAC items on all the time when we are activated.
These produce 1500WATTS of real clean looking 120VAC and has internal batteries. When these were new they would last 4-5 hours but now I'm lucky to get 45 minutes ouot of them...
They do have external BATTERY CONNECTION PLUG on them but I never looked into what DC VOLTAGE they would need.
The items I have plugged into these units continue to operate when the shore power is disrupted and then when I get my INVERTER system up and going then they still continue to provide 120VAC from the 120VAC INverter side and recharge the internal batteries. They also beep alot as described above haha...
It does keep me on the air with my radio while I get things setup again when the shore power goes down...
