SwanScout 303G - Power Bank per orologio Google

Charges my watch quickly.

portable and convenient. Very helpful for charging my watch away from an outlet, and especially in the refrigerator (which speeds of charge times in my experiences) . charges a little more than 2 full charges on it's tiny battery.

I actually never used this, I gifted this to my kids. They have told me it’s been working well for them- they use it for their pixel watch and they stated it works well and charges fast! No issues with this item so far, no damages to the item when shipped either! Based on their reviews, this would be a recommendation!

I think I use this the opposite of the way it is intended but it works for me. I take my little puck when traveling unless I am going somewhere I don't expect to have easy access to an outlet. I prefer this charger at home because it is much more stable, unlike the little puck that often loses contact with the watch if jostled. I do wish it started charging when not plugged in without pressing the "on" switch but at least it does start automatically when it is plugged in. It is lightweight when I do take it somewhere.

I'm very pleased with almost everything about this charger. Solid magnetic connection, charges as fast as the OEM cable, decent size battery for multiple charges (6 full charges?), solid build for travel.

Two small problems leave me wanting more, though:

1. I have to remember to press the power button to begin charging, which is different from the cable setup. I realize why, but I prefer setting-and-forgetting.
2. It's really big compared to other chargers, some of which clip onto a keychain. This is the size of your watch band. For hotel travel, not an issue. But in a backpack on a hike, every ounce and square millimetre counts. Now if I could reverse-charge a phone (obviously just an emergency charge) I might be able to leave a power bank at home. But this doesn't do that. It's much larger that what I find for Apple Watch chargers.

So...great for a week-long Caribbean vacation. But for cord-free trips in the woods, it's bigger than I'd want. A bit expensive but worth it if you want to leave your charging cable at home or need portable power.
