Well worth the price in exchange for convenience

I charge my laptop while on the road and this product has paid for itself over and over again. All you do is plug it into your Socket in the car and turn the switch on and with it's automatic fan. It never gets too hot and shuts down and has a lengthy cord to stretch about the car. I love this product!

solid product

The BESTEK 300W Car Power Inverter is a reliable, compact DC-to-AC converter that makes powering devices from your vehicle easy. It delivers up to 300 W continuous power with a 700 W peak, and includes two AC sockets and dual USB ports for charging phones, tablets, and small electronics on the go. Built-in safety protections and a smart cooling fan add peace of mind, and its lightweight design is great for travel or emergencies. While it's a good product overall, I personally prefer a 65 W USB-C port over the standard 30 W for faster charging.
