Use bike battery as power socket

[cwah]

hello,

I'd like to use my battery to power things. I'd like to have the most reliable and compact inverter for 48v+ battery.

The best I've found is this:
http://www.ebay.co.uk/itm/Pure-Sine-Wave-power-Inverter-300W-12V-24V-48V-DC-to-AC-120V-230V-solar-system-/112151153179?hash=item1a1cbaca1b:g:s1cAAOSwaEhZJ~oD

Anyone know anything better before I purchase?

actually this one is 650g only:

does it worth it?
