I have a Google Pixel 3. It takes about 40 minutes to charge from completely empty to 100% with a Google fast charger. I wasn't expecting it to charge that fast, but basically it will charge all day? Give me a break! BTW I only use the shortest charger with two longer ones, I think it will last about a month. I connected my phone at 30% about 2.5 hours ago and now at 41%. Using the handle would charge faster. I agreed with the company when in doubt and asked for a replacement, thinking maybe I just got an unreliable one. No, it's the same. Too bad I didn't trust other "reviews".
