This charger is exactly what my daughter needed. She's in her second year of college and has several devices she carries pretty regularly. In an effort to cut down on the number of separate charges she was carrying, I decided to get this charger. Her Surface Book 3 has the highest charging requirements out of all the devices. This charger handles it with ease.
I do recommend that you buy one of the Anker charging cables rated for higher watt charging. There were a couple of times she thought the charger wasn't working, but it was due to faulty charging cable or cable that couldn't supply the advertised wattage. Anker cables have performed flawlessly.
