I bought a 10 foot DC extension cord for my 140 watt inverter. $5 from Walmart - was cheaper than the one on amazon. It works well!
For $4, I also went to a thrift store and picked up some used AC to DC chargers for my various appliances. I got ones with different sized plugs. I am putting all my DC items in a cloth bag and keeping them to use in my car, until I get a nice deep cycle battery for my home.
