Mine has standard mains sockets on the front, but it looks like the one you are thinking about has IEC sockets on the back, which it a bit inconvenient, as you will have to chage the plug as you say.
This would be a better one, as its the same design as mine.
I have the APC Back-UPS ES 550 UPS AC 230 V 330 Watt 550 VA 8 Output Connector(s)
Hi, Thanks for the info have found a few of these so will look into it more. Would you recommend what some other guys have done with these ? Where they connect up two marine batts instead of the two small internal batts ? I have not really got the space at the moment but just wondered for future upgrade purposes. Cameron
I would not recommend this, as the unit is not designed to operate for a long time, and may overheat.
It would also invalidate any guarantee.
