Review on 💪 Powerful 220V/240V to 110V/120V Step Down Converter and Travel Adapter Combo for Hair Styling Tools, CPAP Machines, Electronics - Use your USA Devices Anywhere! by Ken Perry

Spent a week in France. It was very helpful. I bought a couple of dual voltage plug adapters that we brought. I have this for single voltage cells and a phone charger in one case. Worked great. I was able to simultaneously charge a portable battery, 2 cell phones, one with fast charging, and run the CPAP machine. At one point I tried to pull too many amps. There were too many of the above devices plus my laptop and the device was no longer providing stable power to the outlets. All I did was unplug the laptop and turn off the power for a few seconds and it worked fine again. Definitely recommend!
