The are excellent chargers with the convenience of USB A and USB C ports. Using the 2 ports individually is still giving ample power to charge devices. However, using both ports at the same time is going to result in slower than ideal charging. I would suggest using this as a universal charger that can use either size port, just not at the same time. Comes in two pack though so it’s still an excellent value, especially with 2 USB C to USB C cables included.
