Review on 🔌 Kinverch 750W Power Inverter: DC 12V to 110V Car Converter with 2 AC Outlets and USB Port - Reliable Power Supply for Your On-the-Go Needs by Hesham Peltier

I really like it so far. I haven't pushed it to the limit since I bought it a little bigger for my app to avoid this, but the app works great for turning it on and off and monitoring power usage and battery voltage. Bluetooth seems to have a good range. It consumes around 12W in standby mode (turned on but not charging) but I usually just leave it in BT mode which only consumes around 1-2W and use the app to turn it on when needed. The app even has an "auto-off" feature, so you can just leave it on for as long as you like, and then automatically turn it off for you - just in case you tend to forget - and don't waste those 10. 11 watts in simple.
