They do what there supposed to do.

Good value for the money.

Because the S21 Ultra doesn't come with a charger it was a pain to research to get the right one. If you see the 45w charger AVOID IT AT ALL COSTS! The phone will limit it to be slower than the base (slowest) charger. The perfect charger is 25-30w. This will fast charge your phone so fast WITHOUT ruining the battery life. Go from death to fully charged in around 15 min and if you're using your phone normally it will last well over 8 hours. If you set the phone for performance & use a lot of draining apps like gaming of video heavy things, it will drain a lot faster but it's still reasonable & the charger is so fast even if you only have a few minutes to get a charge it will be a significant charge. Plus you get 2 in a pack! This charger is literally perfect.

Works great

Took a bit more than an hour to fully charge a Galaxy S21. One for home and one for office.
