Another excellent Anker product
Color: Black
I always start my peripheral search with Anker. As all my Anker equipment are, it’s solid, compact and works as promised. If I get really picky, when I have my Air Pods charging, the band of my Apple Watch takes some extra effort to tuck in above it (a little more height would be appreciated, although it would work against its compactness). That’s a really minor gripe. I love that the magnet is strong and that the orientation can be changed from landscape to portrait without removing it from the mount. It will fit into a suitcase easily and the AC adapter is small. I couldn’t be happier with it!

The only MagSafe charger you’ll ever need..!!
Color: Black
Yet another AWESOME charger from Anker..!! Unlike cheaper MagSafe chargers, this one almost reaches out and grabs your phone when you’re attaching it for charging.. Holds your phone securely for bedside mode at night and there’s no need for a 25W charger that’s more expensive.. Just a perfect size and works well… looks no further…. This is the bedside charger to get..!!

Actual, honest-to-goodness fast charging
Color: Black
After unsuccessfully buying two different so-called "fast" chargers that completely lied about their charging ability, specifically for the Apple watch, I finally bought this one. What a world of difference! I have an Apple watch ultra, which is fantastic on battery life, and I appreciate that I can actually wear it while I sleep. I have to charge it about every day and a half, which means that sometimes I need to top it up while I'm at work. (Alternatively, I could be a slave about charging it every day at home, but part of the reason I switched to the Ultra is to not have to be that obsessive about charging.) Anyway, I needed a good charger at work. I ordered one that claimed to be 5W watch charging, and it blatantly lied. It took over an hour to get about 20% of a charge. I ordered another, similar results. This one is night and day different. My watch will fully charge at the posted speeds Apple boasts about with fast chargers. If it's running a little low during the day, I can pop it on the charger for 20-30 minutes and have enough juice to last through my hour+ swim workout, no problem. The phone charger is fast, too, and if you use a magsafe case, it has a very firm hold. Without a magsafe case, your phone may drop off the charger (mine did), which is frustrating. Since I have another magsafe charger at home, I just bought a new case (they're cheap) and now I'm super happy with this. The contact charger on the back will work to charge your phone (or a second phone) or earbuds, too. Very happy with this purchase. It's a bit pricier than the cheapo other brands, but it actually freaking works and charges quickly. It's worth the money.

Secure Mount With Premium Feel
This phone mount feels incredibly sturdy once installed. No shaking or movement while driving, even on rough roads. The design looks clean and factory installed instead of bulky like a lot of other mounts. It holds the phone securely and keeps it easy to access for navigation.
