A:AnswerYes, it does. I asked an employee while at the store and he said that although the box doesn't say, it came out before the 5 so it does indeed work on the 4 and 5.
A:AnswerIt's a USB cable that plugs into a USB port and accepts at most 5V. If you're most likely asking (or concerned) if it works in dual voltage USB chargers, either 120/240, then yes.
A:AnswerThank you for your inquiry! Even though the Insignia™ Magnetic Charging Cable officially lists support up to Apple Watch Series 8, Apple has historically maintained the same magnetic charging standard across all Apple Watch models, including the Series 10. So, while the cable may not support fast charging (which requires a USB-C charger and a compatible fast-charging puck), it should still charge your Series 10 at the standard rate without any issues.
A:AnswerThere is an app on the phone. I hated my Samsung watch as the apps are so hard to find (at least for me they were). Keep digging through the apps til you find the pair with phone. Samsung to Samsung should be fairly simple once you find the link of your phone. Be patient and keep trying.
A:AnswerI have the apple 8 watch and it works great. I'm not sure how that computes to the apple ultra. Maybe it will say on the box which watches it works with. I'm sorry I don't have the box it came in.
