Caught mention of this on another forum, thought I'd post it here.
If you are in the market for a good deal on a Pure Sine Wave inverter check out the Zamps at Lowes. I only looked at the 300w before posting. $37 at Lowes, same model on Amazon is $133.
Compared to https://www.amazon.com/Zamp-solar-ZP.../dp/B00O5C6EOK
No idea if all the Zamps at Lowes are similar or how long this will last, hopefully it's not just a typo at Lowes. If I hadn't just installed a 1000w I'd grab one.
Just checked the 600w, $50 vs $200!!! Hope it's not a case of too good to be true.
