AnkerMagGo Power Bank for Apple Watch, Officially Certified, 10,000 mAh Compact Battery Pack with Built-in USB-C Cable, 35 W Max, for iPhone 15 Series, Samsung, iPad, AirPods and More

UPDATE: Anker reached out with top tier customer support. They helped me troubleshoot my slow charging speeds and it’s just that the watch itself is designed to charge at different rates depending on several different factors. They explained it very clearly and in a helpful way and it was enough for me to just keep using it in good faith. I can safely say this thing works pretty well especially by comparing it to other chargers. I tried to use other watch chargers with a wattage read and found they were the same as well with slow charging speeds. After taking this on multiple trips, it will definitely charge your watch in a pinch. I may have just had some errors in my first overnight charge but after putting it through its paces, I went a full 5 days just using this to charge my watch and even my phone once or twice and it saved me packing a two cables or fighting someone for an outlet. Is this worth the full price tag? I’m not exactly sure. I think I found my value out of it. Basically saves you from packing or buying a watch and usb c cable. Plus it has enough capacity to charge my watch several times over. Really no more complaints!Okay so two things here. I bought the other battery which has the same built in cable, but features a wall outlet plug in. Super useful when travelling. No fussing with a power brick or worrying about forgetting it plugged into the hotel wall, but whatever. Then I saw this. I was annoyed because if I had seen this one that has a watch charger built in, I would've scooped this up in a heartbeat! Against my better judgment, I bought this one too and gifted the other charger to my girlfriend. Sadly I did realize that this battery bank doesn't have a wall outlet charger. Not really this thing's fault, it doesn't advertise that it does, but man I just saw the same style battery and thought it did. Bummer. Not a big deal. What IS a big deal is that this thing comes with little circle stickers for you to put on the watch charge to help "stabilize" it. Usually a red flag when a product has a "fix" for an issue, but whatever. I love Anker products. I apply the sticker and plug my phone in. The phone charges at about 20w which I can see because of the neat little digital readout. Super cool. I have one of those cables that reads out the wattage and can confirm, I plugged it in to charge at 30w, battery confirms 30w, and even better yet, it gives an estimate to the battery being full. Very neat!Now for the terrible part. I popped my watch onto the charger....it charges at .8w. That's right. Not the max 5w, not 2w, not even 1w, just .8w. To give you an idea of how "fast" it charges, I put my watch on the charger at around 80%, went to sleep, woke up about 6 hours later to a 94% charged watch. Now I figured, maybe it's because my watch is nearly fully charged. Today I put my watch on there at 10%. Still .8w. I moved it around for a bit and I got up to 2w. Then it'd drop back down to .8w. I took the sticker off, no change, applied a new one, same result. Despite having some cool features, this is a return for me and off to find a replacement!

I am quite happy with this battery. The size is great for taking it with me wherever I am going. The fact that it can charge any usb-c device with the built-in cable and my Apple Watch make it quite useful. I love the screen. I’m a big fan of data, so I love being able to see charging rates and exact amount of battery remaining. It handles pass-through charging wonderfully. I have tried with my watch attached, having the built-in cable connected, and having the usb-c plug connected. It handles charging and pass-through whether the built-in cable was connected to power or being powered through the usb-c port. I’ve only had it for a couple of weeks. So far it is great. I will be able to see overall durability over time.

Game changer. I love that this has a built in Apple Watch charger. This is all you need when traveling. Chargers both the watch and phone with speed. The built in cable is superb convenient. The LED dip lay is useful to see outgoing watts and remaining battery.

This charges both my phone and watch at the same time quickly. I can probably charge both twice before needing to recharge it. It also recharges quickly so I have little down time. It stays at a cool temperature and doesn’t heat up. It also displays how much charge is in it and the display changes when flipping the watch charger out or leaving it folded in.The only drawback for me is the size and style. It seems like a small brick shape so it can be awkward to fit in small purses. However, this is still my go to charger when traveling so I don’t need to pack too many cords and chargers.

A bit pricy for a 10,000mAh battery but very versatile in its use. Perfect for charging your watch anywhere and everywhere. It also has a USB-C out that will charge devices at up to 30W don’t quote me on this. It does vary between devices. The battery also has a built-in display to show output of power and input of charge.Perfect companion for my Apple Watch as a standalone charger or on the go while on the road.

This review is for the A1657 model. Bought this to get an on-the-go charge for an iPhone and an Apple watch. Seems to work well. Charging rates similar to regular device chargers. The only thing I wish is that it could recharge itself faster (limited to 30W input) but two hours will get you a full recharge.

Love this product! Charged my devices super fast and I love that there is a watch charger included. This is an amazing charger for traveling! Will be buying more!

Very well made and I like the flexibility of how to set it up based on if I’m charging my watch or not. I like that the cord becomes a carrying loop as well. It’s well made, and I’ve used it and charged it several times and no issues. I really like the digital display showing how much charge is remaining - that’s something most don’t offer so it really helps knowing how much more charge I have before it needs to be charged. It’s small enough to put in a purse or bag for travel. I plan on using it for the year and then buying it for stocking stuffers if it holds up.
