Review on 🔋 Powerful Vertiv Liebert PSI5 1500VA Lithium-Ion UPS: Reliable 13500W 120V Mini Tower Line Interactive AVR with UPS Lithium Battery Backup - Single Phase (PSI5-1500MT120LI) by Matt Simpson

Very heavy despite its thin appearance. Arrived damaged, bent, main switch fell apart. Only $100 returned. Ask the seller to use the correct shipping service! Please pay attention to the AC input plug before purchase, it is NEMA L50-30P(R), if you plan to use in residential areas, you need an adapter. Do not connect to the dryer socket, it is 240 V! There may be an issue with proper cooling, for some reason a rear fan isn't installed at all.
