“I've been doing some extensive testing on some inverters on the market comparing high end (expensive) to midrange and even non reputable brand names, this inverter comes reasonably in the mid-range that definitely can provide continuous 1200w supply. It would have been 5 stars, except for that they sent me a review request and in that showed a 25% cheaper price to what I paid a month ago. So while its $299 its an even better deal, pity I paid the $399 price!”
