Review on 🔌 500W LVYUAN Car Power Inverter – 12V to 110V with 2 US Sockets, 2 USB Ports, LED Display by David Carmody

For the most part, the inverter worked well. I connected it to a 12V LiFePO4 battery and it provides AC power to my network devices when needed. Good - The voltage display is handy to know the remaining battery capacity - The inverter goes into fault mode when the voltage gets too low. - The design seems good for the most part - As far as I can tell, the design looks ok, but I'm no expert. - There are internal fuses. - The included clips are decent wire size. Bad - iPhone will not charge. I think the diagram for the D- / D+ USB pins was wrong. I see an attempt to do this, but the positives and negatives seem mixed up. Again not 100% expert but as far as I can tell this is the problem. (attached image) - The fan is quite noisy. This is a 12V fan that is tied to the input voltage. When operating on battery voltage, which can be as high as 14.6V+ on some batteries/systems, the 12V fan is overloaded. I feel like there's limited variability, I can hear it speeding up and slowing down a bit, but the difference isn't huge. I think the biggest problem with noise is that the aluminum case amplifies the fan vibration noise. Hoping to solve this problem with the rubber o-rings I ordered. Other important points. It would be better if many of the wires had internal shrink tubing to improve security.
