Review on 🔌 KOOSLA Pure Sine Wave Inverter: 300W Power Inverter with 60W PD USB-C, Car DC 12V to AC 110V Car Plug Adapter Outlet by Michael Skerving

Firstly, the fan does not turn on. I only had a 90w TV, the case got too hot to touch after 2 hours of use, the fan and overheat protection didn't seem to work. Stay away from this inverter, safety is a priority. This inverter does not work well with LIFEPO4 lithium batteries because it is picky about the battery voltage. LIFEPO4 batteries have a voltage of more than 13V when fully charged, and this inverter cannot provide a stable output voltage of 13VDC to 115VAC. I have tested this with my drill drawing from 0 to 280 watts and the drill is not stable (it is only stable with 11 to 12 volts DC input). It works great with lead acid batteries as they typically stay between 11 and 12 volts. I made my own XT60 10awg cable and thought the cable, spade lugs or screws had a bad connection after spending so much time researching only to find out that the inverter didn't work well with LifePO4 batteries . You get what you pay for, in my case I got burned.
