Verified Purchase

Medical Equipment Needs This Backup

Perfect emergency backup for my wife's oxygen concentrator. Utility power failed 4 times in one day, scrambling to switch to a oxygen cylinder each time. Never have to rely on the power grid plus it can recharge with the included solar panels.

Extreme power with every possibility

This is my second unit, the first one I gave to my son in need. I have been using to power our 35' while charging through EcoFlow 90 alternator generator connected to 2 Battleborn LIFe4 batteries charging with 800 watt solar panels in pass through mode. Loving the freedom to travel on our own power.
