Review on 🔌 Optimized Belkin USB-C Car Charger with Integrated USB-C Cable (4ft/1.2m / 15 Watt) for Samsung Galaxy S10, S10+, S10e, Google Pixel 3, Nintendo Switch and Additional Devices by Chris Horton

I bought this charger to charge my Galaxy S10. When I first plugged it in, it showed "Fast charging" for a few seconds and then switched to slow charging. This happened to all three of my Galaxy S10s in my house as well as my old Galaxy S8. I called Belkin support and they suggested I request a replacement from Revain. However, the replacement behaved the same way, leading me to conclude that the charger wasn't capable of maintaining the constant current needed to quickly charge the Galaxy S phone.
