Power banks have come a long way in just a few short years. What used to be a way to get a quick top off on your phone has evolved into devices capable of charging multiple laptops at full speed. Thanks to USB-C and fast charging, many modern power banks can now deliver up to 140W, rivaling wall chargers in both power and efficiency while still being portable enough to carry in a bag. There are a few brands that are well respected and known for their high-quality power banks, so I wanted to see who made the best high-powered charger that could charge at least 100W, has a built-in cable, is TSA approved, and also provides some charging stats in real time. Here are the best ones I have tested so far!
