The lightweight 1200 watt I purchased for a recent primitive cabin retreat... I hooked mine up with 2 160 watt solar panels each morning and afternoon to recharge to 75% or better on a very clear sunny day. Amplification: The lightweight portability is a big plus as other brands 1200 watt power supplies are bulkier and at least 5 pounds heavier. During my 4 day cabin retreat it supported a LED lamp, a small USB fan, a USB LED small ambient globe and a AirSense11 CPAP. Served me well every night of uninterrupted stand alone power, as well as brewing 2 cups of coffee and 1 hour of news radio every morning.
